1、 Before and after emergence

During this period, the plant is in a very critical period. Drought must not be allowed, otherwise it will affect the seedling emergence rate, but do not give too much water. Waterlogging will also affect the growth of the plant. After the seedlings grow, they need to control the water. The just right state is most suitable for the growth of the plant. When the plant reaches the vigorous stage of growth and development, it needs to give more water

2、 Weeding

When the seedlings of the plant grow for about 10 days, it is necessary to carry out the first weeding activity, and then every 10 days, so as to prevent weeds from robbing the nutrition of the plant

3、 Intercropping

When the seedlings grow for about 10 days, they need to be intercropped, because the two seedlings are too close to each other, which is not good for either one, the nutrition is not enough, and the maintenance of light is not good. It is OK to control the distance of about 5cm. After the final seedling setting, it is good to control the distance of about 9cm
