1. Black potato has a short growth period, requires relatively concentrated fertilizer, and applies high-quality organic fertilizer, diammonium phosphate and urea. After fertilization, the soil is deeply cultivated. The black potato planting should be thin and should not be dense. It can be pressed and ridged in time after sowing. At the same time, the herbicide and the new high-fat film are mixed and controlled, and the mulch is covered. 2. Field management. After the seedlings are unearthed, it is necessary to break the membrane and release the seedlings in time, and seal the seedling holes with wet soil.
