It has about 1,400 years history that transmitted from India to China. India is the most yield country of castor oil plant seed, the next is China，Brazil and Thailand. After 1990s, the yield of costor-oil plant increase in times because of the arising of hybrid varieties, and the benefit is improved gradually from 300 yuan to more than 1000 yuan. Predict according to the expert, after several years, the regular varieties of castor oil plant will be replaced by hybrid varieties completely. Castor oil plant production will be growing to well-breed, large scale, high efficiency, industrialization. The planting of castor oil plant is a more reliable program. According to the statistic, it can be make a basic balance of produce and sale that the annual output of castor oil seeds in China is about 400,000 tons. Now, the annual produce of castor oil seeds in China is no more than 200,000 tons, the shortage is more than a half. There are about 20 big and middle size castor oil processing factories in China now, and only there are 8 factories among of them that can process more than 10,000 tons per year. Because of the shortage of raw material of ricinus, the most enterprises are bothered and in lack of the raw material. So, ricinus planting never have the problem to sell.
