近年来,随着玉米秸秆还田面积的增加,给小麦苗期生长发育带来一些不良影响,为此必须抓好秸秆还田小麦苗期管理。据总结有关实践经验,一般秸秆还田后种植的小麦应抓好“一查二补”。一、及时查苗补苗秸秆直接还田的麦田,由于大量秸秆翻入土壤中,使耕层土壤松暄空隙度增大,常常使小麦种子与土壤接触不良,而导致失墒使种子落干,造 In recent years, with the increase of corn stalks return to the field, wheat seedling growth and development to bring some adverse effects, we must do a good job of wheat straw seedling management. According to summing up the relevant practical experience, generally planted wheat after planting wheat should do a good job, “a check two fill.” First, timely check seedling stalks directly back to the field of wheat, as a large number of straw into the soil, so that the plow soil turf porosity increased, often make wheat seeds and soil poor contact, leaving the loss of moisture so that the seeds dry, Made
