Due to the postponement of the maize growth period, the high temperature in the middle and late September, the increase of soil water consumption and evaporation, and the lack of periodic precipitation, resulted in insufficient ploughing of the soil. After the autumn harvest, straw smashing and rotary ploughing practice actually make it easier to form soil suspensions in the plough layer after sowing in wheat fields and run through the wind, causing difficulties in emergence or emergence of seedlings after sowing, which is not conducive to tillering and cultivating strong seedlings before winter. Even cause hanging roots or due to drought, dead seedlings and young seedlings. Therefore, late sowing of wheat should pay attention to repression after sowing, solid soil, so that the soil moisture moves upward, promote wheat seeds and soil closely, to lay the foundation for emergence and uniform, all, homogeneous and strong. In combination with the method of soil preparation, the corresponding measures are as follows: 1. Strengthen repression For sowing machines that use rotary tillage and soil sowing, increase the pressure or weight of the repression reel and increase the pressure of the town; or sow and repress it with pressure stone mortar, sand drum, etc. The compaction of the surface soil after sowing will create a soil environment conducive to the emergence of wheat. Second, artificial pressure on the seeded wheat fields, artificial antegrade pressure in time after sowing, to reach the practical soil, raise the earthworms, ensure the safety of wheat emergence.
