India and Brazil are the main growing countries. Castor oil is used as lubricating oil and laxative. In the tropics, this plant can reach 10? 13m (30？ 40 feet). In temperate climate, only 1.5? 2.4 million annual plants. Ricinus communis is only one kind of castor, but there are hundreds of natural types and many horticultural varieties.

An annual or perennial herb of Ricinus of Euphorbiaceae. Originated in East Africa, it was introduced to America through Asia and then to Europe. Ricinus communis from China was introduced from India and distributed from Hainan to the south of 49 north latitude of Heilongjiang.

Is castor in the north of China?

Yuquanshan Ricinus communis

Deep ploughing before winter, applying organic fertilizer to ripen the soil, and planting in pieces. In the south, gaps are used for planting. Seed development does not need high temperature, and seedlings can tolerate it. 0℃? Left and right low temperatures. Direct seeding or seedling transplanting can be carried out. Spring sowing in the north should be early, and sowing can be carried out when the temperature is stable at 65438 00℃, so as to prolong the growth period and increase the yield. Perennial castor can be planted with perennial roots. Before overwintering, the aboveground parts should be cut off and covered with heat preservation and antifreeze. Harvest when most capsules are dark brown or yellowish brown and cracks begin to appear. Is the main pest Fusarium wilt? Leaf blight? , bacterial spot disease and cutworm, cotton bollworm, thorn moth, castor silkworm moth.

The oil content of castor seeds is about 50%. Castor oil is an important industrial oil, which can be used to make surfactants. , fatty acid glyceride? , aliphatic diol, drying oil? , sebacic acid, polymerization stabilizer and plasticizer, foamed plastics and elastic rubber, etc. And it is a high-grade lubricating oil raw material? . Can I also take medicine? It has a laxative effect. Cake powder is rich in nitrogen, phosphorus and potassium, which is a good organic fertilizer and can be used as feed after detoxification at high temperature. Stem bark is rich in fiber and is the raw material for papermaking and rayon.

Morphology and characteristics? There are two kinds of cultivated species: oil and oil and medicine. There are many cultivated varieties in China, including medium-sized seeds with thorns, medium-sized seeds without thorns, small seeds with red stems, small seeds with white stems and small seeds with wax leaves. Everyone likes to resist high temperature and freezing, but they are resistant to alkali and acid and have strong adaptability. However, it is not tolerant to low temperature at seedling stage and will freeze to death at-1℃. Seed propagation. The flowering period is long, and pollen is released when flowering, mainly by wind and insect pollination. Ricinus communis has a well-developed root system with a depth of 2-4 meters, and its lateral roots extend horizontally for about 2 meters. The stem is soft and tough, hollow, and branches from section to section. The number of branches per plant is related to variety and planting density. Perennial castor has thick stems, lush branches and leaves, more than 5 meters high, and the stem circumference is 15 ~ 20 cm. The stems and leaves are green or purplish red. The plants are covered with white wax powder, which is smooth and hairless. Leaves are palm-shaped, and some are chicken feet-shaped. Flowers unisexual, racemose panicle, female flowers in the upper part of panicle axis, red style, male flowers in the lower part. Occasionally, plants have mixed bisexual flowers or only a single female flower. Capsule with thorns, sparse without thorns, 3 rooms, each room 1 seed. The leather shell is smooth, hard and brittle, red to dark brown, with light patterns on it. The oil content of seeds is about 50%. The optimum growth temperature is 20 ~ 28℃. The accumulated temperature from emergence to maturity needs 2000 ~ 3500℃. When the average temperature is lower than 20℃, the growth and development are slow, and the yield and oil content are affected.

Euphorbiaceae? (Euphorbiaceae) Ricinus communis is an annual or perennial herb. Castor oil is an important industrial oil.

Castor (castor? communis)

History and communication? Ricinus communis originated in East Africa, and then spread to America and Europe through Asia. Ricinus communis in China was introduced from India, and it has been cultivated and utilized for over 300 years. It was recorded in Tang Herbal Medicine (AD 639). For a long time, sporadic planting, mostly in fields, low slopes, houses or roadside gaps. The harvested castor seeds can be used for oil extraction, with high viscosity, low freezing point, cold and high temperature resistance, no freezing at -8 ~- 10℃, no solidification and denaturation at 500 ~ 600℃, and incomparable characteristics of other oils. It is an important raw material for chemical industry, light industry, metallurgy, electromechanical, textile, printing, dyes and other industries and medicines. Oil meal can be used as fertilizer, feed and raw material of activated carbon and film. Since the 20th century, the production of castor oil has developed rapidly because modern industry needs a lot of high-grade lubricating oil.

Castor oil is inedible. It has high economic value and is a medicinal laxative. In textile, chemical and light industry, castor oil is used as dyeing auxiliary, lubricant, plasticizer, emulsifier and raw material for making coatings, paints, soaps and inks. ?

Castor oil was treated with concentrated sulfuric acid to obtain sulfate with good surface activity (commonly known as Turkish red oil). Castor oil can be dehydrated to obtain dry oil with double bond of yoke. A variety of products can be obtained by treating castor oil under different hydrogenation conditions, so castor oil is widely used in various industrial sectors. Castor oil is the closest to pure complex triglyceride, and only olive oil (containing about 80% oleic acid), safflower oil (containing more than 70% linoleic acid) and tung oil (containing about 85% eleostearic acid) have this characteristic. ?

The content of unsaponifiable matter in castor oil is less than 65438 0%. The vitamin content is low (about 0.05). ?

Castor seeds have high oil content. Because of the different uses of oil, the methods of oil extraction are also different. Medicinal castor oil is cooled by hydraulic press. Squeeze, the temperature does not exceed 50℃, otherwise some impurities will be dissolved in oil and cannot be used as medicine. The oil obtained by cold pressing is called castor oil 1. After the cake meal is crushed, it is squeezed or leached again to prepare No.3 castor oil (No.2) for industrial use. Castor oil extracted by direct pressing or pre-pressing with screw oil press can only be used as industrial oil.

China is located in the south of 49 north latitude from Hainan to Heilongjiang. North China and Northeast China have the largest output, followed by Northwest China and East China, and most other places are planted sporadically. There are semi-wild perennial castor beans in the tropics.

Cultivation? Castor is a deep-rooted crop. In the large-scale planting areas in northern China, deep ploughing and soil weathering are often carried out before winter to improve the performance of water storage and fertilizer conservation. The south uses gaps to sow seeds. I like temperature, but seeds don't need high temperature to germinate. Seeds with hard shells and slow water absorption should be sown in early spring and can be sown when the temperature is stable at 65438 00℃. Seedlings can also be transplanted. Seedlings can tolerate low temperatures around zero. Early sowing castor in the north can prolong the growth period and increase the yield. Perennial castor can also be planted with perennial roots. Before overwintering, cut off the aboveground parts and cover them with soil or farmyard manure. Straw or film can also be used to prevent freezing and keep warm. The plant spacing should be 65 ~ 100 cm. When 1 ~ 6 leaves are true, the terminal buds of the main stem are removed to promote the growth and development of the lateral branches. ? When most capsules are dark brown or yellowish brown and cracks begin to appear, they can also be harvested by stages. Perennial castor can be harvested continuously for about 10 years. The main diseases are Fusarium wilt, leaf blight and bacterial spot disease. The main pests are cutworms, cotton bollworm, stickleback moth and castor silkworm moth.
