1. The role of castor
Ricinus communis was often used as lubricating oil and emollient in the former countryside, but its seeds contained ricin. However, with the passage of time, its name was gradually forgotten, and it was easy for livestock to eat by mistake, so people paid no attention to this plant.
Moreover, the current rural environment is not as good as before, and the places where it can be planted are basically occupied by other crops. However, castor can treat diseases such as ear, nose, mouth and facial nerve paralysis, and it has obvious effects in relieving swelling and pain, diminishing inflammation and treating constipation. After manual processing and packaging, it is also a drug with great demand.
2. The market of castor
In the global market, the demand for castor oil is still very large, because the role in industrial use is very large, and the oil output is quite high, and China is also a big country that needs castor oil, so it provides a good market environment for planting castor oil in a large area.
Moreover, Ricinus communis is a very drought-tolerant and easy-to-survive plant, and the state also has supporting policies. Generally speaking, Ricinus communis is a plant with low investment and considerable income, and it is a plant that is very suitable for extensive cultivation in rural areas.
However, little is known about this plant in rural areas. There is not a full understanding of its planting methods and market conditions, and most of the things planted in rural areas are mainly rice, wheat and corn, and there is no clear place to buy castor, so few people take this step.
Therefore, it is normal that castor bean, which was common in rural areas when I was a child, was rare in most rural areas. Because of the lack of understanding of castor bean, few people planted it. In addition, nowadays young people cultivate less land and most of the land is contracted, so it is difficult to see this plant again.
