I hope to know the planting and harvesting time of rape.

Rapeseed is sown in autumn and winter, and in late September and early June. 10. It is usually harvested in May. When mature, seeds are cracked and sown, purple-black, yellow.

Rapeseed oil content is 35~50%, which can be used for oil extraction or feed. The extracted oil is what we usually call vegetable oil. In China, rape is mainly concentrated in Wuyuan, Jiangxi, 10,000 mu terraces in Hanzhong Basin and Jiangling, Luoping Plain in Yunnan and Menyuan Plateau in Qinghai.

Extended data:

The development of rape industry in China Rapeseed is the most important oil crop in China, and its oil content is 33% ~ 50%. Since 1995, the perennial planting area is100000 mu, and the annual output of rapeseed is nearly1000000 tons, accounting for 40% ~ 45% of the total output of oil crops (excluding soybeans); At the same time, it also produces about 6 million tons of rapeseed cakes.

The protein content of the cake is as high as 40%. The amino acid composition of rapeseed protein is reasonable, and the lysine content is equivalent to that of soybean, while the sulfur-containing amino acids such as lysine and methionine are higher than that of soybean protein, which is the largest source of high-quality feed protein to be developed and utilized in China. Rape is not only used to extract edible oil and feed.

In the food industry, margarine and artificial protein can also be made. It is also widely used in metallurgy, machinery, rubber, chemical industry, paint, textile, soap making, paper making, leather, medicine and other industries, and has important economic value.
