The best sowing date of winter rape

The best sowing date of winter rape is from September to 10.

Winter rape planting time can be selected from September to June at 65438+1October, middle and late-maturing varieties can be selected from late September to mid-June at 65438+1October, and early-maturing varieties can be selected from mid-June at 65438+1October. Different regions have different climates, and the planting time is slightly different. The planting time can be selected according to the local climate.

Winter rape is usually planted in September-65438+10. Because it is a winter crop, it needs to go through a low temperature dormancy period to blossom and bear seeds. If you want to plant rape in March, you can choose spring rape varieties. Their sowing time is very flexible, and they can sow in spring and harvest in summer or harvest in autumn. However, you should pay attention to the difference between spring rape and winter rape. Spring rape seeds are smaller, have lower oil content, and have higher requirements for soil, water and fertilizer.

Introduction of rapeseed

Rape, also known as Brassica napus, is the seed of cruciferous crops. Rape has long pods and full seeds. The oil content of rapeseed is 37.5%-46.3%. According to different types of rape, its oil content is also slightly different. It is one of the main oil crops and honey crops in China, and its seeds are one of the main varieties of oil-pressing raw materials.

Rape is cultivated all over China, which can be divided into winter rape and spring rape. Its planting area accounts for more than 40% of the total area of oil crops in China, and its output accounts for more than 30% of the total oil production in China, ranking first in the world. According to botanical morphological characteristics and agronomic characters, rape can be divided into four categories: Brassica napus, Brassica napus, Brassica juncea and Brassica juncea. The latter has a small planting area, and most countries in the world only grow the first three kinds of rapeseed.
