Requirements of direct seeding rape on crops in the first season

The first stubble of rapeseed is mainly rice. Due to the limitation of its mature harvest time, direct seeding rape has a late sowing time and a short vegetative growth period, which affects the increase of yield. Direct seeding rape should be sown at the right time, and the selection of varieties in the previous crop is very important. Generally speaking, early or middle maturing rice varieties should be selected, which not only have high yield and good quality, but also meet the sowing date requirements of direct seeding rape. At the same time, because rape is a dry field crop and is not resistant to waterlogging, the previous rice should sun up the field early to prevent it from drying too late and affect the growth of rape root system.
