What Are Oil Crops?
Oil crops are a type of crops that contain a large amount of fat in the seeds and are used to extract oil for food or as industrial and medical raw materials. There are mainly soybeans, peanuts, rapeseed, sesame, castor, sunflower, perilla, and oil beans. The oil content of the seeds can reach 20-60%. Fiber crops, such as cotton, flax, hemp and other seeds also contain a large amount of oil, which is an important raw material for the oil industry. Among the perennial woody oil plants are coconut, camellia, oil palm, walnut and so on. The oil meal left over from the press contains a large amount of protein and other nutrients, which can be used to produce non-staple food as well as a good refined feed and fertilizer. [1]

- In order to develop oil crop production, in addition to grasping several large-scale oil crops, new sources of oil crops should be developed, such as the development of woody oil crops such as camellia, walnuts, olive oil, tung oil, and sassafras. Woody oilseeds have strong adaptability, high yield, good oil quality, low investment, high efficiency, and do not occupy cultivated land. At the same time, a variety of herbal oils and a variety of woody oils should be implemented simultaneously. Oils are used for many purposes. Except for people's consumption, they are widely used in industry, medicine and national defense. Oil cake is a good feed and fertilizer. Therefore, we must pay attention to the development of oil crops while focusing on the development of grain and cotton.
- The cooking oils people use to cook are extracted from the fruits or seeds of some oily crops with high oil content. Common oil crops are mainly oil palm, peanut, soybean, sesame, rape, sunflower and so on. Peanut beans and some dried fruit kernels are good oils. The more widely planted oil crops in China include peanuts, soybeans, and rape.
