① Select drought-tolerant varieties. Drought-tolerant varieties have strong drought resistance and less yield loss under drought and water shortage conditions. Generally, early-maturing varieties are not as drought-tolerant as late-maturing varieties. ② Choose suitable drought-resistant sowing methods. Seize the opportunity, grab the soil moisture for sowing, grab the time for soil preparation in spring when there is little rain and drought, and grab the soil moisture for sowing when the ground temperature reaches 8 ~ 12℃; Suppress and improve soil moisture, and introduce soil moisture for sowing. This method is suitable for the situation that the surface soil moisture is lost and the bottom soil moisture is still sufficient. In order to ensure that the seedlings are planted at one time, the soil should be compacted again before sowing, so as to make the deep water rise along the capillary, improve the water content of the bottom soil and increase the water content of the sowing layer, and then sow. Sowing deeply, sowing with soil moisture, drying the topsoil to a depth of 6.6-7 cm, sowing with soil moisture when the bottom soil moisture is good, sowing deeply or digging dry soil, and sowing with wet soil; Soil moisture conservation and water storage, stubble sowing, that is, directly sowing after harrowing stubble land, or sowing without ploughing after corn straw is fully or semi-covered; Sitting in water to increase soil moisture and sowing with soil moisture is an emergency drought-resistant sowing method, such as lifting water, sowing in high-yield pits, transplanting seedlings, etc., in the case of severe drought and no soil moisture in the plough layer. ③ Vigorously promote the use of new dry farming techniques. Increase the application amount of organic fertilizer. Deeply plough 30 cm to increase soil water storage; Soil testing and formula fertilization. Deep application of base fertilizer, point application of topdressing or strip application. Popularize ridging and film mulching cultivation techniques and straw returning techniques. Use drought-resistant and water-retaining chemicals such as soil water-retaining agent, soil surface evaporation inhibitor and plant transpiration inhibitor to reduce soil water evaporation or plant transpiration.
