1. Planting time: Mao Cong is generally planted in April. Because it is not afraid of cold and has a high yield, it is widely distributed in the northeast of China. Moreover, this plant grows very fast, and it usually takes only two months to harvest. After it is unearthed, it needs to be dried and then stored in a ventilated place.

2. Soil preparation and sowing: Before planting Mao Cong, the land should be selected, which is usually planted in a place with soft soil and good permeability. Before planting, it should be turned over deeply, and then leveled and fertilized. The fertilizer is mainly farmyard manure, and a small amount of compound fertilizer is also needed. After that, make a border for the land and bury it in it according to a certain density, while keeping a good distance.

3. Water and fertilizer management: After planting in Mao Cong, it is necessary to water the soil according to the degree of dryness and wetness. If the water content is too high, it will not be watered temporarily, which will help to improve the ground temperature. And you can't water it too much, otherwise it will cause it to rot. In addition, its root system is shallow and its ability to absorb nutrients is not strong, so it can be supplemented with a little ammonium sulfate or potassium sulfate.

4. Pest control: Mao Cong needs to be disinfected by spraying drugs one week after emergence, so as to prevent diseases and pests. It should be noted that spraying should not be carried out in rainy days, and chlorothalonil or agricultural streptomycin should be used as drugs. If you want to kill insects, you should spray it quickly, which can effectively kill pests such as onion thrips.
