Kale, also known as headless cabbage and sea cabbage, originated in southern Europe. Kale is novel and beautiful in appearance and rich in nutrition. There are green leaves and kale in red, purple, yellow, white, flowers and other colors for viewing.
Chinese cabbage is a kind of green leafy vegetable with comprehensive nutrition. The content of mineral elements such as vitamin C, carotene, iron, calcium and potassium is more than three times that of ordinary Chinese cabbage. It is the first choice for treating children's night blindness and supplementing calcium. It is low in calories and is an ideal food for bodybuilding and weight loss.
The edible part of kale is its wrinkled tender leaves, which can be peeled off from a plant and grow new tender leaves. The young leaves of kale can be eaten in many ways, such as fried meat, fried vegetable, pickled with sweet and sour seasoning and so on. Western food is often used to make salads.
Safe drug use of flowers
First, observe the rules for the safe use of pesticides.
In flower planting, banned pesticides include methamidophos, methyl parathion, parathion, monocrotophos, ammonium phosphate, bhc, DDT, toxaphene, dibromochloropropane, chlordimeform, dibromoethane, herbicide, aldrin, dieldrin, mercury preparation, arsenic, lead, dichlorvos, fluoroacetamide, phos and tetramine.
Second, take safety protection measures
The applicator must take prescribed safety protection measures to prevent poisoning. The rest of the liquid medicine and the cleaning liquid of the applicator should be treated safely, and it is not allowed to be spilled at will. Empty containers are not allowed to be reused. Empty containers should be properly collected and disposed of, marked as safe storage or centralized treatment.
Abandoned and expired pesticides must be disposed of according to the relevant provisions of the state, and cannot be discarded casually, so as not to cause phytotoxicity to flowers or poisoning to people and animals.
Third, planting scientifically and reducing drug use.
Through farming measures, some pests and diseases can be eliminated, and conditions that are not conducive to the occurrence of pests and diseases can be formed. At the same time, it is necessary to improve the ability of flowers to resist pests and diseases, such as garden cleaning, treatment of sick and disabled people, reducing the source of pests and diseases, rational close planting, increasing ventilation and light transmission in greenhouse, timely removing waterlogging, reducing field humidity, scientifically formulating fertilizers, etc., so as to make flowers grow healthily and improve their ability to resist pests and diseases.
Fourth, strengthen physical prevention and control.
In order to avoid the emergence of drug resistance of pests and diseases, physical control should be chosen as far as possible. For example, yellow stick insects can be used to trap and kill aphids and leaf miners, and silver-gray films can be sprinkled in the fields to drive away aphids, which can also improve the light intensity. Using the phototaxis of many nocturnal insects, we can use light trapping, bait trapping and other methods to eliminate pests, and we can also use insect nets to reduce the probability of pests.
Verb (abbreviation of verb) biological control
Biological control is also a measure to reduce drug use and avoid drug resistance of flowers.
One is to use bacteria, fungi, viruses or their metabolites that can cause the disease and death of pests to control pests. Usually, the harmful microorganisms of pests are artificially cultivated, then made into powder and sprayed to kill pests. For example, Bacillus thuringiensis in bacterial preparations is extremely toxic to the larvae of LEPIDOPTERA insects and has excellent killing effect. The experimental results show that the effect of killing insects with fungi is also very good. If Beauveria bassiana parasitizes insects and snails such as Lepidoptera and Coleoptera, it can kill pests very effectively. Trichophyton chrysosporium is highly pathogenic to whitefly. Great progress has also been made in the research and application of using viruses to control insects, and nuclear polyhedrosis virus is the most widely used one. Insect virus has strong specialization, strong pathogenicity and lasting effect. In practical application, virus preparations are often made into aqua, platinum agent, wettable powder and so on. , sprayed or applied to the soil to control pests.
Secondly, the growth, development and even death of pathogenic microorganisms in flowers are inhibited by antagonism between microorganisms and metabolites of some microorganisms. This substance is an antibiotic. For example, the flower bacterial fertilizer code 5406 can control some fungal diseases, bacterial diseases and mosaic virus diseases of flowers.
The third is to control pests by using the biological chain, food chain relationship or parasitic relationship in nature. For example, using solar bees to control cotton aphids; Use dragonflies and mantises to prey on pests and so on.
The effective components in plant immunity and plant juice can also be used to control pests and diseases. For example, the aqueous solution of garlic juice can prevent and control many kinds of germs. Using plant physiological active substances to control pests and diseases is a hot research topic at home and abroad, and it is one of the most promising methods. In addition, using bioengineering methods to control pests and diseases is also a new development trend, such as transgenic technology.
Sixth, prescribe the right medicine.
The prevention and control of flower diseases and insect pests should first understand the causes, infection cycle and ecological environment of diseases and insect pests, and master the laws of time, place and scope of their occurrence, so as to prescribe the right medicine.
1. The middle part of the upper leaves of plants burned by non-communicable diseases drugs (1) is reddish, but there is no mildew in the affected area after the rain. (2) Water damage will lead to rotten roots and easy lodging. The leaf edge of frost-damaged seedlings was first scorched and wrinkled, and there was no mildew in the affected area after rain, and the stem skin was damaged. (3) The upper and middle leaves are wrinkled and drooping due to drought. (4) Pollution causes the leaves to be dirty and easy to wipe. Fertilization leads to bud withering and stagnation. (5) The plant grows slowly, the leaves are deformed and dull, and the leaves fall off from bottom to top along the stem.
Knowledge of flower protection
Which flowers are not suitable for spraying water on leaves? For example, flowers with fluff on their leaves often cause leaf rot because water drops on them are not easy to evaporate. Such as: African violet (Zizhumei), buttercup begonia, Erythrina macrophylla and so on.
Pseudobulb, among the leaves of Clivia, is also afraid that water, especially in bud stage, will affect the drawing of arrows.
The tubers, leaf buds and flower buds of cyclamen will rot when exposed to water.
For flowering plants, it is also necessary to avoid spraying a lot of water on the leaves, which will lead to mildew of petals, affect fertilization and reduce the flowering and fruiting rate.
2. How to disinfect the soil?
Disinfectant can be disinfected with commonly used 84 disinfectant, and the concentration should not be too high, generally 2% ~ 3%. Use a sprayer during disinfection to achieve uniformity. Spraying and turning over the soil.
3. What water should I use to water the flowers?
According to salt content, water can be divided into soft water and hard water. Hard water contains a variety of salts. If it is used for watering flowers for a long time, it will cause brown spots on the leaves of flowers and affect the ornamental value. Therefore, it is ideal to use soft water. In addition, you can choose mild water sources, such as lake water, river water and pond water.
Now, with the improvement of living standards, tap water is more convenient for us to use. Because tap water itself contains a lot of chlorine gas, the water temperature is relatively low, which is not suitable for direct watering of flowers. It needs to be left for 1-2 days before it can be used. Or use a container with a relatively large opening and put it indoors for one day and one night.
Fish water also contains certain nutrients, which is also good for watering flowers.
In addition, there is another method of watering flowers with cold water, which is also effective. You can try.
Finally, I would like to remind you that watering flowers must not use water containing soap or washing powder, and it must not contain oil stains, which is extremely harmful!
Miscellaneous talk on flowers and plants feng shui
People are greatly influenced by the environment, what they see with their eyes, what they hear with their ears and what they eat with their mouths. Smell and think, the areas that must be paid attention to in feng shui of urban life.

The original purpose of geomantic omen is to strengthen the connection between man and nature, and flowers and the endless natural gas it produces constitute an important bridge. They can prevent the gas from sinking gradually in dark corners, and can also smooth the gas that just flows through the cloister and fluctuates greatly.
Under special circumstances, flowers will produce unusual energy to match the environmental conditions at that time.

Therefore, when flowers are placed in a special way, they will be an important source of qi.
Healthy and lush flowers are important promoters of qi, and they can bring endless energy to the family. Flowers, especially blooming flowers, represent luck, because if their bright colors are combined with the correct five elements, they can promote the achievement of eight desires such as wealth, love, career, marriage and making friends.
Artificial flowers can produce less curative effect, but there is still some if they can be kept clean and tidy for a long time. In the field of geomantic omen, flowers have other functions. For example, they help to stimulate the stagnant qi in the corner and make it active, softening the yang generated by sharp, sharp and angular objects.
In addition, placing flowers in areas that lack enough energy can make the orientation active and make the room look wider. When the bookcase is covered with curtains and office equipment is placed in the corner, flowers still have the function of neutralizing and decomposing toxins.
Many geomantic omen have symbolic meanings, because things in the environment are thought to emit some form of energy, some representing good and some representing bad. The gas emitted by flowers is considered to be suitable for special feng shui norms, such as eight diagrams and five elements. By combining them, we can balance the energy of a place through the interaction of the five elements.
Flowers are alive and will change.

Oriental flowers represent family and health, belonging to the wooden line in the five elements; Will be placed in the southeast, representing wealth and success, belonging to the wooden line in the five elements; Putting flowers in the south indicates fame and knowledge, and the five elements belong to fire; Putting flowers in the north means having a career and belongs to the waterline of the five elements. However, because the wood line will destroy the center, similar to the gold line, flowers should be avoided in the southwest, northeast and central areas. Of course, we should also avoid putting it in the direction of gold and silver, such as the west and northwest.
Flowers can not only enhance the eight desires of life, but also increase oxygen content, improve humidity and strive for powerful space energy. Flowers are one of the most effective feng shui methods, which help to balance and coordinate energy, make the room full of fragrance and beautify the visual effect.
Flowers can cure diseases, nourish the mind, make the family prosperous, the population prosperous, coordinate the biological field at home, and obtain good feng shui.
