The first is to optimize the selection of improved varieties and scientific variety layout. According to the natural ecology and production conditions, reasonable variety collocation, select the national or provincial approval, in the local planting performance of excellent maturity suitable maturity, good yield and stable yield, yield increase potential, strong stress resistance, dense resistance to lodging, disease and insect resistance, suitable for mechanical operation of excellent corn varieties. In the northwest and southwest film mulching cultivation areas, varieties with a growth period of about 10 days longer than open field cultivation can be selected. Do a good job of seed coating, prevent "white seeds" from going to the ground, and carry out seed treatment such as drying in advance if possible.

The second is to classify land preparation, and sow in the right time and moisture. For the northern spring land preparation plot, the straw should be transferred from the field before thawing, and the straw treatment methods such as no-tillage mulching, strip tillage mulching, and crushing and mixing can also be used according to local conditions, and the soil can be rotated and stubble eliminated in time after thawing, and organic fertilizer can be applied in combination with land preparation if conditions permit; The arid plots can be planted on the original ridges if they do not have the conditions, and the spring waterlogging plots can be cleaned and dried as soon as possible, and the ridges are scattered by ploughing and ridges, and the shallow seeds are sown in a timely manner after the ground is dry.

The third is to reasonably increase density and build high-yield groups. The cultivated layer can be sown when the ground temperature of 0-10 cm is stable through 10 °C, and the planting density is reasonably determined according to the ecological conditions, variety characteristics, soil fertility, management level, etc., and the planting density is moderately dense. In the northeast and northwest dry farming areas, 4000-4500 seedlings per mu are generally maintained, and the seedling density per mu can be increased to more than 5000 plants for plots with high sowing quality, high yield corn varieties with high density and lodging resistance, sufficient fertilizer and water supply, and good overall production conditions.

The fourth is to prevent and control diseases and cordyceps, reduce losses, improve quality and increase yield. It is predicted that corn diseases and insect pests will be more serious this year. Northwest China focuses on underground pests, aphids, leaf mites, cotton bollworms, corn borers, stem rot, large spot diseases and other pests and diseases. Disease and stress resistant varieties and high-quality coated seeds should be used, and secondary precision coating should be carried out if necessary. Combined with agronomic measures to prevent and control weeds, the plots with good soil moisture were used as "one kill", and the plots with poor soil moisture, less rainfall and sandy soil were used as "one kill and one supplement". Strengthen the dynamic monitoring and early warning of the occurrence of diseases, insects and weeds, and carry out unified prevention and control in a timely manner, and "one spray and multiple promotions".
