Adopting the “four reforms†measures can effectively avoid the raping of rapeseed roots and promote the robust growth of rape seedlings. One is to change wet cultivation and wet cultivation to dry cultivation. Paddy fields transplanted with rapeseed should be drained and dried 5 to 7 days before ploughing, in order to improve soil structure and enhance soil permeability, so as to create good environmental conditions for rapeseed growth. The second is to change the hole to transplant plants for the ditch. If the clay soil is heavy, if it is transplanted in the rainy weather, it will easily cause water accumulation in the seedlings, and rape seedlings will easily rot after transplanting. Using the method of ditching seedlings, soil and fertilizer are used to root the roots. The roots of rape seedlings are dry and air-permeable. After transplanting, they return to green, and there is no dead phenomenon. The third is to widen shallow shallow trenches for narrow trenches. Rapeseed transplanting fields are suitable for narrowing tillering and deep-opening, which will help eliminate water in the soil, reduce soil moisture, and increase oxygen in the soil. The fourth is to change flood irrigation and drought resistance to artificial irrigation and drought relief. When the rapeseed is transplanted and the weather is long and dry, it is necessary to manually water and drought, and flood irrigation is not allowed. If there are rot-root dead seedlings after transplanting, they should drain water in time, cultivate loose soil, and see seedlings fertilize to promote new roots, so that the rape seedlings can resume normal growth as soon as possible.

Insect rapeseed "four changes" against rot
The rot-root dead seedlings often appear after transplanting rape, which is mainly due to the high soil moisture in paddy fields. The higher the soil water content and the longer the duration, the higher the rate of death of the rape roots.
