一、推广玉米秸秆还田好处多玉米秸秆富含氮、磷、钾、钙、镁、硫等矿质元素和大量的有机质,是一种较好的肥源。秸秆还田能加速生土熟化,改善土壤理化性状和生物活性,提高土壤中水、气、热的综合作用,增强土壤通透性,提高土壤蓄水保肥能力。另外,玉米秸秆内有大量的化学能量,是土壤微生物生命活动的重要能源,因此,秸秆还田还可以增强土壤微生物活性。总而言之,玉米秸秆还田有很好的经济效益、生态效益和社会效益,是实现农业可持续发展的一项重要措施。
First, the promotion of the benefits of corn stalks more corn stalks rich in nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and other mineral elements and a large amount of organic matter, is a better source of fertilizer. Straw return to the soil can accelerate the maturation, improve soil physical and chemical properties and biological activity, improve soil water, gas, heat combined effect, enhance soil permeability, improve soil water retention ability. In addition, there is a large amount of chemical energy in corn stalks, which is an important energy source for the life activities of soil microorganisms. Therefore, straw returning to soil can also enhance soil microbial activity. All in all, corn stalks return to the field has very good economic, ecological and social benefits, is an important measure to achieve sustainable development of agriculture.
