Rape winter seedlings must not only have larger seedlings, strong seedlings, but also have a strong ability to resist cold. How much winter rape seedlings are appropriate should be determined according to local production conditions and cultivation levels. The following criteria are generally used as the criteria for winter seedlings in rape: Winter seedlings should have 11 to 12 green leaves in the winter, with a root neck thickness of more than 1.5 cm. Winter seedlings should have 8 to 10 green leaves in winter, with a root neck of more than 1 cm. Weak seedlings have only 6 green leaves below the winter, and the root neck is less than 1 cm thick. On the cultivation and management of the winter hair seedlings, it is necessary to timely and appropriately supplement the wax fertilizer or the moss fertilizer, and to strengthen prevention and treatment. In addition to the size of seedlings to measure the advantages of overwintering seedlings, they can also be identified from leaf color, root weight, and plant sugar content. For example, the winter and strong seedlings in the Yangtze River basin should be green and purplish in the leaves, and the middle head should be divided into normal colors.
