There are many Rain Water in summer, which can easily lead to stagnant water in the field, so it is necessary to choose the land with high terrain and convenient drainage and irrigation as the low seedling raising. If the seeding method is adopted to raise seedlings, it will lead to uneven seedling emergence and cause waste. Therefore, it is suggested that we use nutrient soil or nutrition bowl to raise seedlings, if we use the method of on-demand, it is not only easy to manage, but also can emerge neatly and consistently. High temperature in summer and low seedling raising can cover the sunshade net, reduce the temperature of the seedling ground, and reduce Rain Water's scouring of leaves. Opening in cloudy days or at night will also cause mainly seedlings, and open the sunshade net one week before planting, so as not to alleviate the mutation of seedlings after planting, which will prolong the slow seedling stage and affect the yield.

2. Strengthen the management of disastrous weather

Sowing too early, long-term temperature below 10 degrees, Chinese cabbage through vernalization bolting, will also cause no heart, or long-term temperature below 35 degrees, will also seriously affect the package. Therefore, we should pay attention to fertilizer and water management, increase the application of phosphorus and potassium fertilizer and organic fertilizer, control the application rate of nitrogen fertilizer, restrain the crazy growth of plants, and supply water scientifically during the pericardium period. Water supply should be uniform and adequate, sometimes more and sometimes less, sometimes dry and sometimes wet, so as to prevent the leaves of Chinese cabbage from curling and wilting.

4. Pay attention to diseases and insect pests
