What are the requirements of direct-seeded rapeseed for the preceding crop?

(Agricultural Wealth Network) The previous crop of rapeseed is mostly rice, and direct-seeded rapeseed is limited by its maturity and harvest period, so sowing is relatively late and the vegetative growth period is short, which affects the increase in yield. Direct-seeded rapeseed must be sown at the appropriate time, and the choice of variety for the preceding crop is very important. Generally, early-maturing or early-to-mid-maturing rice varieties should be chosen that are both high-yielding and high-quality and that meet the sowing period requirements of direct-seeded rapeseed. At the same time, because rapeseed is a dryland crop and is not tolerant of waterlogging, the preceding rice should be drained and dried in the field appropriately early to prevent the field drying from being too late and affecting the growth of the rapeseed root system.
