What should rapeseed seedlings pay attention to?

What should rapeseed seedlings pay attention to? Please guide rape because of its small seeds and high emergence rate, it is easy to appear large sowing rate, dense emergence, crowded seedlings, deterioration of nutrition, poor growth and high weak feet of seedlings in the later stage. After transplanting to the field, such rape seedlings have poor stress resistance, slow turning green, many dead seedlings, easy lodging in the later stage and low yield. Therefore, rape seedlings, we must control the amount of sowing per unit area, sparse sowing, uniform sowing as far as possible. For rape seedlings, the ratio of seedbed area to field area is generally controlled at about 1:5, that is, the seedbed area per mu of field should be about 0.2mu (two parts of land). The seeding amount per mu of seedling bed is generally controlled at about 0.5 kg, that is, only 0.1 kg (100 g) of seeds need to be purchased per mu of field. In the actual sowing, the sowing amount can be adjusted according to the specific conditions, such as small seeds, early sowing, high bud rate, high soil preparation quality, suitable soil moisture, fine management, less insect pests in the seedling stage, and less sowing, otherwise, it should be sowed a little more. however, the sowing amount per mu of seedling bed should not exceed 0.6 kg. In order to ensure uniform sowing, seeds should be mixed with sifted fine soil and spread evenly. In addition, the 3-leaf stage of rape after emergence should also be combined with weeding seedlings to ensure that the seedlings are evenly distributed and the leaves are not matched with leaves. Only on this basis can we strengthen the management in order to cultivate strong seedlings and lay a good foundation for rape high yield in the future.
