If the optimum time sowing is excessively pursued, a rough sowing rotary tillage sowing mode is generally adopted or the sowing time is delayed, the sowing quantity can be increased by the two modes, and unnecessary waste of seeds can be caused. The soil humidity determines the rotary tillage effect, and the soil humidity should be controlled within a proper soil humidity range, and the soil tillage operation is most suitable for 15-16 degrees under general conditions. Generally, the method is used in ploughing and tedding days, and completely depends on a natural air drying method, so that the process has too many factors, and needs 1-2 days, which has great influence on wheat planting in rice and wheat crop rotation areas with tight stubbles. In addition, under the condition of returning straws to the field, the soil humidity is high, rotary tillage is more difficult to process and easy to cause blockage, and meanwhile, when the soil humidity is reduced in the later period and the furrow soil room is large in gap, the moisture is easy to lose. Therefore, fine tillage is particularly important. For pests and diseases from soil moisture: because the traditional rotary tillage does not have the capability of killing pests and diseases, the diseases, pests and weeds can be aggravated by high soil humidity, but the current instantaneous high-temperature treatment is the main physical method for killing the pests and diseases.
