Rapeseed is usually planted in what month. What should I pay attention to when planting rape?

Rape is one of the main raw materials of oil crops in China, and it is widely planted in many places in China. Rapeseed is planted in March and April in spring and August and September in autumn every year. Different regions and climates have different planting times. There are differences between north and south in China.

Pay attention to when planting rape:

? First, the choice of seeds: First, we should choose rape seeds with good quality and full grains. The selected seeds can be dried in a sunny place, which can sterilize and improve the germination rate. Soaking in salt water or warm water can also play a role in sterilization and germination. Secondly, varieties should be selected according to natural conditions such as topography and climate in planting areas, such as high yield, lodging resistance and disease resistance.

2. Soil preparation and fertilization: 1. It is necessary to select and arrange seedbeds, and choose dry land or vegetable garden soil with loose and fertile soil, convenient irrigation and drainage, flat terrain and no rape planted for more than 2 years as seedbeds, and apply sufficient fertilizer. Keep the humidity and irrigate in time to ensure the emergence rate. When it is long enough for transplanting, transplant it to the field in time. 2. Live broadcast. Plowing, fertilizing, adjusting the moisture content of ridges and choosing the spacing are just like planting wheat. After long-term emergence, it is necessary to intersperse seedlings, remove over-dense seedlings, weak seedlings and diseased seedlings, leave good seedlings and supplement sparse seedlings. Spawning can be eaten by people.

Third, weeding, pest control, fertilization and watering during the growth period: weeds should be removed in time during the growth period of rapeseed. The common diseases and pests of rape are Sclerotinia sclerotiorum, downy mildew, aphids, caterpillars and so on. According to different diseases and insect pests, choose the corresponding pesticides for prevention and control. Rape needs a lot of water and fertilizer when it grows and develops, so it should be watered and fertilized in time to ensure the normal growth of rape. Although rape likes wet, it is not tolerant to waterlogging, so it needs to drain excess water in time.
