生产实践证明,抓好冬小麦早春田间管理,可促进小麦早返青,快生长,实现丰产丰收。1、锄划。各类麦田在早春冻融期都应进行锄划。锄划可切断土壤毛细管,减少水分蒸发,提高地温,缓解土壤含水量和地温之间的矛盾。因此,无论麦田是否冬灌,都应抓好这项措施。2、耙麦。早春土壤解冻后及时耙麦,可以提地温,保土墒,破板结,松土透气,促进土壤微生物活动,又可减轻病虫害,尤其是大面积麦田,
Production practice has proved that good grasp of winter wheat field management in early spring, wheat can promote early green, fast growth and achieve high yield and bumper harvest. 1, hoe draw. Various types of wheat fields in the early spring freeze-thaw period should be carried out hoe draw. Hoe draw can cut off soil capillaries, reduce evaporation of water, increase ground temperature, alleviate the contradiction between soil moisture and ground temperature. Therefore, no matter whether the wheat fields are irrigate or not, we should do a good job of this measure. 2, rake wheat. Early spring raking soil in time after raking wheat, you can mention to warm, soil moisture, breaking plate knot, loose soil permeability, promote soil microbial activity, but also reduce pests and diseases, especially large areas of wheat,
