Rose is a light-loving plant, but too strong light is not conducive to bud development, but grows in places with insufficient sunshine and slender branches. It takes about 45 days from germination to flowering, and the optimum growth temperature is 15-25℃. In this temperature range, the flowers are large and beautiful, but they grow slowly at 30℃, and the flowers that bloom above 30℃ become smaller and lighter in color. When seedlings are planted in pots for 2-3 years, they should be pruned, and old roots should be cut off to promote new roots, but pruning should not be too heavy. Pay attention to root stretching when planting. Spring, summer and autumn should be placed in a sunny, well-ventilated and stagnant place.
After Tomb-Sweeping Day, the Chinese rose was carefully pruned when it came out of the cellar. Choose the robust branches of Chinese rose to stay, and cut off other transverse branches, weak branches, cross branches and over-dense branches. The selected branches should have 3-5 bud holes from the base, and all the above branches should be cut off, so that the plants can absorb a lot of nutrients from the soil and supply the long-term growth needs of leaf buds and flower buds left after pruning. Remember to prune after germination. Pruning will affect the first flowering, and the growth height should be consistent. Each plant can retain 3-5 main branches, with a maximum of 7 branches.
Potted roses are not dried and watered, but watered thoroughly. In summer, the weather is hot and the evaporation is large, so potted plants should be watered more, especially at night, which is 1 times. When the temperature exceeds 30℃, roses will grow poorly and bloom less. Some people think that it is a bad thing to topdress more fertilizer because of insufficient fertility. In midsummer, topdressing is generally not needed, and only thin fertilizer is applied to the vigorous branches, twice a week1-. If we can shade properly after 1 1 in the morning and bask in the sun after 4 pm to avoid the high temperature at noon, we can also resist the weak sunshine before noon and afternoon, which is beneficial to photosynthesis and accumulate nutrients for the next crop. After pruning, it can be fertilized and mixed with 50% human excrement and 2% calcium superphosphate. In mid-February, 3% human excrement or 1% urea can be used as topdressing, and urea can also be sprayed before and after the rain. Fertilization is not suitable when the new buds are red. At this time, fertilization will cause young roots to be injured, so that plants will wither or stop growing, so special attention should be paid.
Mid-term pruning of Chinese rose is needed, which mainly includes cutting off the budding branches of grafted seedlings, cutting off residual flowers and redundant buds after flowering, cutting off delicate flower branches from the base after the first flowering, and cutting off the remaining robust flower branches under 2-3 leaves of residual flowers. The second flowering can still be pruned by thinning the weak branches, leaving strong branches and strong buds.
Rose still needs pruning 1 time before overwintering, but not too early. When pruning Chinese roses, we should not only choose strong branches, but also pay attention to the consistency between master and slave. Large-flowered varieties should have 4-6 strong branches, and each branch should choose one side of 30-40 cm to grow strong buds, and the upper branches should be cut off. For vines and vine varieties, remove old branches, weak branches and pests and diseases.
2. Knowledge about Chinese rose flowers
1. Soil quality requirements: flower beds and flower beds should be selected in a good position with flat terrain, convenient drainage and sunny ventilation.
The best soil is loose and slightly acidic soil (about PH 6.5), and the soil with high alkalinity can be treated with ferrous sulfate. Before planting, apply sufficient base fertilizer (both organic fertilizer and inorganic fertilizer), dig deep into the soil and rake the flat surface, preferably in a sunny seedbed. Pot is mixed with 30% garden soil, 30% pond mud, 30% humus soil and 10% fine cinder, and it is best to apply a pinch of fine cake fertilizer at the bottom of the pot when planting.
Second, water fertilization: water should be dry and warm. After the big and small seedlings are buried, they should be rooted before planting trees. The physiological activity of rooting needs sufficient oxygen and proper moisture, while the growing trees need sufficient moisture and proper oxygen. Generally, it is rainy and windy in spring, so water the seedlings and then loosen the soil. In the future, we should master the wet and dry conditions of the soil, the size of the seedlings and the amount of rain.
In summer, when the sun is hot and the soil temperature is too high, water it after 5 pm (the sudden cooling of the soil affects the growth of seedlings). It rains heavily in autumn, so pay attention to drainage.
Roses are drought-tolerant and afraid of water accumulation, so try to reduce the number of watering according to the specific situation. To overwinter in the open air, it is necessary to apply fertilizer once after reasonable pruning in the early stage of hibernation and pour enough water. Always pay attention to maintain good drainage, ventilation, water and fertilizer conservation performance.
In order to accelerate the growth of seedlings and cultivate ideal tree types and beautiful flowers, topdressing should be done in time. Rose likes fertilizer, and the requirements are not strict. Depending on the growth of seedlings, topdressing under roots or foliar spraying (urea, potassium dihydrogen phosphate, high-quality fertilizer, ferrous sulfate) can be used.
According to the weather temperature, apply less and apply more to avoid premature and fierce application, resulting in fertilizer damage. Third, rose pests and diseases: common diseases of roses include black spot disease and powdery mildew, which are unavoidable for ordinary flower farmers and individuals. Therefore, we should pay special attention to the early management of seedlings and keep the plants strong, which in itself resists the invasion of natural foreign bacteria.
Big and small seedlings should be dipped in the roots with bactericidal drugs before they are buried in the soil (500 times carbendazim and thiophanate can be used). Spraying mancozeb, chlorothalonil, carbendazim and thiophanate-methyl every 7- 1000 days in spring (Bordeaux mixture and sulfur mixture are also acceptable). It was found that 40% dimethoate emulsion and metronidazole 1000 times solution can be used for spiders and aphids, and they can be mixed with fungicides.
Huangmei and autumn rain are the peak periods of black spot disease, and the incidence of wet, hot and rainy in summer is also very strong. During this period, the interval of application should be shortened (once every 7 days). Precautions for spraying: generally 8: 00 am 8:00- 10/0, 4: 00 pm-7: 00 pm.
It is best to spray when there is no wind on a sunny day. 4. Pruning requirements: After the seedlings are cultivated in spring, all the buds in the first and second stages should be pulled out (the next leaf of the bud should be cut off) to save nutrition and promote the growth of branches, and the residual flowers on the big trees should also be cut off. Grafted seedlings should be removed from the rootstock in time, and residual flowers should be cut off after summer flowers.
Cut off long branches, cross branches, overlapping branches, long branches, layering, etc. Make preparations for watching movies during Christmas, New Year's Day and Spring Festival.
In winter, the whole plant should be pruned, that is, each plant has 3-5 branches and each branch has 3-5 buds, so that the rose is a positive tree species and prefers light to shade. The suitable temperature for most varieties is 15-26℃ during the day and 10- 15℃ at night. In winter, the temperature goes to sleep at five degrees Celsius.
It can withstand the low temperature of MINUS 15 degrees Celsius, but it is most afraid of the cold wind. In summer, it enters a semi-dormant state at 35 degrees Celsius.
In areas where there is a big difference between day and night, flowers are more beautiful in pattern, color and fragrance. After years of exploration and practice, we have a systematic experience in the cultivation and management of Chinese rose. The survival rate of cutting and grafting is constantly improving, and plants grow rapidly, which makes Xinwei a better place than Miao Zhuang.
1. Soil quality requirements: the garden should be located well, with flat terrain, convenient drainage and sunny ventilation. The best soil is loose and slightly acidic soil (about PH 6.5).
Before planting, apply sufficient base fertilizer (both organic fertilizer and inorganic fertilizer), dig deep into the soil and rake the flat surface, preferably planting in the sunny border. Pot is mixed with 30% garden soil, 30% pond mud and 30% fine cinder, and it is best to put a pinch of fine cake fertilizer at the bottom of the pot when planting.
2. Water fertilization: Water should be irrigated dry and drained wet. After the big and small seedlings are buried, Mr. Root, and then plant trees. Rooting requires sufficient water and proper oxygen. Generally, it is rainy and windy in spring, so you should water the seedlings after planting and loosen the soil after watering.
There is heavy rainfall in autumn, so pay attention to timely drainage. After wintering in winter, after reasonable pruning, apply fertilizer once and pour enough water.
Always pay attention to maintaining good drainage, ventilation and fertilizer conservation performance. Rose likes fertilizer. In order to accelerate the growth of seedlings and cultivate ideal plant types and flowers, topdressing should be done in time.
Top dressing under roots or foliar spraying (urea, phosphoric acid, potassium dihydrogen, high-quality fertilizer, ferrous sulfate, etc.). ). Don't apply it too early and violently, causing fat damage.
3. Pest control: The common diseases of rose are black spot and powdery mildew. If the seedlings are well managed in the initial stage and the plants are kept strong, they will resist the invasion of natural foreign bacteria. Before burying the seedlings, the roots should be soaked with fungicides (carbendazim, thiophanate 500 times). In spring, mancozeb is sprayed alternately every 7- 10 day for 500-800 times. Carbendazim and thiophanate are used once each (bordo solution and sulfur mixture can also be used). It is found that spiders and aphids can use 40% dimethoate emulsion and metronidazole 1000 times, which can be mixed with fungicides. Meiyu period and autumn rainy season are the peak periods of black spot disease, and warm rain is also very strong in summer. During this period, the interval of application should be shortened (once every 7 days). 4: 00 pm 4- 10/0. It is best to spray when there is no wind on a sunny day. 4. Pruning requirements: After the seedlings are cultivated in spring, all the buds in the first and second stages should be removed (the next leaf of the bud should be cut off) to save nutrition and promote the growth of branches. The grafted seedlings should be cut off in time, and the residual flowers should be cut off after the summer flowers, and the long branches, horizontal branches and overlapping branches should be cut off.

Green and white roses indicate innocence, frugality or childlike innocence. Two-color roses indicate more contradictions or interests.
Three-color roses show erudition and affection. Ecological Habits of Rose Rose is a deciduous plant native to temperate zone, which has certain cold tolerance. When planted in most parts of northern China, it is necessary to bury the ground to protect the winter. In other areas, you can overwinter naturally in the open air, and there is no strict requirement on the length of sunshine. You can continue to bloom, stop growing in midsummer, and bloom less.
If you enter the high-temperature greenhouse in winter, it will be evergreen and continue to bloom, but it is not good for the growth in the coming year. Not strict with soil, like loam and clay loam with good neutral drainage, weak alkali resistance, poor growth in sandy soil and acidic soil, strong fertilizer resistance, and need to be supplemented frequently to continue flowering.
2. Propagation methods of flowers in Ji Dan The propagation of Chinese rose is mainly asexual propagation, which can be done by cutting, grafting, dividing plants and layering. The most widely used are cutting and grafting. 2. 1 rose cutting propagation, the hotbed of cutting should be prepared first. We should fill the hotbed with hot things, such as horse manure or leaves, and water and compact it, which will produce a certain amount of heat.
Cut semi-lignified inverted branches from the mother plant of Chinese rose, and the length is about 10 cm. Generally, a branch has three bud eyes. All the leaves at the lower part of the cuttings should be cut off, leaving only the upper two leaves for photosynthesis. Don't leave too many leaves, it will consume nutrients and evaporate a lot of water from the stem. The bottom of the cuttings should be cut into horseshoes and placed in a clear water basin to prevent air drying. Cut in time. The most suitable temperature for Chinese rose to take root is 20-25℃, and generally it can take root above 8℃.
If the ground temperature is lower than 8℃ in winter, it is difficult to take root after cutting. When the temperature rises in spring, besides paying attention to the spraying on the bed surface, the moisture in the bed can not be ignored, otherwise the cuttings will wither due to lack of water, and even the rooted seedlings will die.
The method of checking the matrix is to insert the soil into the depth of 8- 10 cm by hand and take out a little. If you knead it by hand, it means that the water is suitable; if you don't knead it, it means that the soil is short of water. First, make a hole with a wooden stick, and then press the cuttings in the Chacon by hand. The insertion depth is 1/3 of the cutting, and the time interval when the leaves are not together is appropriate. After insertion, water it with a fine watering can in time, and cover it with plastic film after laying the bed sand. Shading 1 week, spraying leaves 1-2 times a day. When transplanting, the roots should be sticky with mud and planted while digging. Adding 1%-2% copper sulfate and 0.50% urea into the mud can not only prevent root rot, but also promote the growth and survival of seedlings.
Before planting, put the broken tiles on the drain of the flowerpot, add the mixed soil, then put the seedlings in a pot filled with soil, treat them in layers and compact them, water them 1 time after planting, put them in the shade for 7- 10 days, move them to a ventilated sunny place, and water them 1 time every day after planting. 2.2 Grafting propagation Grafting is the main means of rose propagation. The choice of rootstock is very important when grafting.
Cuttings are rich, easy to take root, can adapt to local climate conditions, and have good affinity with scions. At present, the commonly used rootstock in China is rose. Grafting usually takes place in dormant period, and branch grafting is adopted before leaf buds germinate in spring.
Bud grafting is commonly used in growing period. 3. Cultivation management of rose The cultivation of rose is divided into protected cultivation and open cultivation.
3. 1 protected cultivation (potted) Chinese rose is a light-loving plant, but too strong light is not conducive to the development of buds, but grows in places with insufficient sunshine and slender branches. It takes about 45 days from germination to flowering, and the optimum growth temperature is 15-25℃. In this temperature range, the flowers are large and beautiful, but they grow slowly at 30℃, and the flowers that bloom above 30℃ become smaller and lighter in color. When seedlings are planted in pots for 2-3 years, they should be pruned, and old roots should be cut off to promote new roots, but pruning should not be too heavy. Pay attention to root stretching when planting.
Spring, summer and autumn should be placed in a sunny, well-ventilated and stagnant place. After Tomb-Sweeping Day, the Chinese rose was carefully pruned when it came out of the cellar.

6. Who can tell me everything about Chinese rose?
Roses like an ecological environment with plenty of sunshine, good air circulation, good drainage and shelter from the wind. It needs proper shade when it is hot in midsummer.
The optimum temperature of most varieties is 15-26℃ during the day and 10- 15℃ at night, which is relatively cold-resistant, but if the temperature is lower than 5℃ in winter, they will enter a dormant state. In summer, if the high temperature above 30℃ continues, the flowering period will be reduced, the quality will be reduced and it will enter a semi-dormant state.
In winter, common varieties can tolerate the low temperature of-15℃, and cold-tolerant varieties can tolerate the low temperature of -30℃. Perfume rose likes warmth, but its cold resistance is worse than that of hybrid perfume rose.
Rose likes fertilizer and should be planted in fertile, loose, humus-rich, slightly acidic to neutral soil with PH value of 6-7, but it has wide adaptability to soil. The relative humidity of air is 75%-80%, but it can grow normally in a slightly dry or humid environment.
It has the characteristics of continuous flowering. If you prune properly after each flowering, water and fertilize, you can bloom endless flowers. Need a clean atmosphere. To prevent pollution (smoke, toxic gas and acid rain, etc.). ) will hinder its normal growth and development.

8. What should I pay attention to when raising Chinese rose flowers?
Rose has an irreplaceable position in history. Rose originated in China and has a long history of cultivation. Known as the "Queen of Flowers". I like a warm and sunny environment. It is cold-resistant and adaptable. Natural flowering is continuous, elegant, colorful, full of fragrance, special flowering period and wide adaptability. It is one of the most important cut flowers and potted flowers in the world. How to plant Chinese rose flowers?
The dark appearance of Chinese rose flowers makes the owner more spiritual. Usually dark things give people a sense of color impact. Imagine if you go home and face four walls, all white, and the furniture you see is light and lifeless. If you suddenly see a thriving Chinese rose next to the TV, the whole person will be refreshed immediately. Because of the sudden change of vision, a person's spirit will be suddenly enlightened, life will become particularly lively and feel particularly special.
Below, we will talk about the maintenance of Chinese rose from several aspects.
1, it takes money to blossom.
(1) The sunshine must be long. The place where Chinese roses are planted should be ventilated and have sunshine for more than half a day. This is the first condition for it to bloom like a flower. If it is placed in a semi-cloudy and semi-sunny place or in a shady place with insufficient light, it can only bloom in spring and autumn at most. Therefore, families whose living conditions can't meet the requirements of lighting, it is best not to plant Chinese rose flowers, but to plant shade-loving flowers and plants.
(2) Prune frequently. Although the sunshine conditions are good, roses will not grow well if they are not pruned for a long time. The method of pruning is. Prune the Chinese rose once a year after 12 months when the leaves fall. The height of the remaining branches is about 15 cm, and the pruning position is about 1 cm above the outward leaf buds. The lateral branches, diseased branches and concentric branches should be pruned at the same time. After May, after each flowering, 2/3 or 1/2 of the flowering branches will be pruned, so that there will be more opportunities to regenerate flower buds. If you want to make the flowers bloom, you can also pick some when the buds are long, which can not only concentrate nutrition, but also achieve the purpose of prolonging the flowering period and opening in batches.
(3) Fertilization should be done frequently and in time. Generally, newly planted or transplanted potted Chinese rose can be cultivated with humus and loose loess, and it is best to add 1/4 rice husk ash or a little bean husk, bean cake or chicken pigeon manure, so that Chinese rose can continuously absorb various nutrients such as nitrogen, phosphorus and potassium from the soil.
(4) change the pot. There is no need to change the pan every year. If you change the small pot into a big pot, it can be done all year round.
2, the maintenance of rose, we should pay attention to the prevention and treatment of diseases. There are several kinds of disease prevention:
(1) Fungal infection:
Black spot disease: mainly affects leaves, petioles and tender shoots. When the leaves are first developed, purple-brown to brown spots appear on the front, and most of them are round or amorphous black-brown spots after expansion. Can spray carbendazim, thiophanate methyl, dyclonine and other drugs.
Powdery mildew: invades young leaves and white powder appears on both sides. Early symptoms are not obvious. After 3-5 days, the leaves are waterlogged and gradually turn green and yellow, which will cause the leaves to fall off in severe cases. Carbendazim and triadimefon can be sprayed during the onset, but Guoguang Naying has the best effect.
Leaf blight: most leaf tips or edges invade, which is yellow spots at first, and then quickly expands inward into irregular large spots. The severely damaged whole leaves withered by 2/3, and the affected parts turned green and yellow, and brown withered and fell off. In order to prevent and control the above diseases, in addition to strengthening fertilizer and water management, diseased branches and leaves should be cut off in winter, and underground leaves should be removed to reduce the initial invasion source. Comprehensive prevention and treatment should be taken when the disease occurs, and fungicides such as carbendazim and thiophanate-methyl should be sprayed.
