玉米秸秆直接还田,能够增加土壤有机质及养分含量,有效改善土壤物理性状,提高作物产量,同时节省用工和运输费用,避免焚烧秸秆造成大气污染。近年来玉米秸秆直接还田技术在我省小麦玉米产区得到迅速推广,但是,玉米秸秆直接还田相对出现了整地不实、秸秆腐烂过程与麦苗争肥、土壤中虫卵、病原菌基数增大等问题。因此,在推广玉米秸秆直接还田技术当中,应重点掌握五个必须。
Returning corn stalks directly to the soil can increase soil organic matter and nutrient content, effectively improve soil physical properties, increase crop yield, save labor and transportation costs, and avoid burning straw to cause air pollution. In recent years, the direct return of corn stalks technology in wheat and corn production areas in our province has been rapidly promoted, but the direct return of corn stalks relative to the site preparation is not real, stalks of straw and fertilizer fight fertilizer, soil eggs, pathogenic bacteria base increased And other issues. Therefore, the promotion of corn stalks directly into the field of technology, should focus on the five must.
