What to pay attention to when rapeseed soil
Before the soil is frozen, to promote the development of the root system of rape seedlings and protect the root system from freezing damage, the rape seedlings must be cultivated. When cultivating soil, pay attention to the following issues:
1. When taking soil, do not take soil too close to the rape seedlings, so as not to damage the roots of the rape seedlings.
2. When cultivating the soil, the soil should be confined to the base of the seedlings. The height of the confined soil is 3~5 cm, so that the central leaves cover the top core, which can well enhance the cold resistance of rape, but the soil should not bury the rape. The growth point of the seedling.
