随着农业生产和农村能源事业的发展,农作物秸秆资源出现了大量剩余。这些秸秆堆积在村头路边,房前屋后,不仅浪费了宝贵的自然资源,而且侵占耕地、妨碍交通、污染环境,甚至引发火灾。作物秸秆除含大量的碳素外,还有氮、磷、钾、钙、镁、硫、硅等多种营养元素,以及富含纤维素、半纤维素、蛋白质等有机物质,在土壤中分解为腐殖质可提高土壤有机碳含量,还可分解多糖,利于土壤团粒体的形成,提高土壤肥力,改善土壤耕性。秸秆综合利用工作是一项长期的利民利国的工作。一、秸秆直接还田秸秆未作任何处理,应用旋耕机、埋草机等机械将秸秆直接翻压还田。二、果园覆盖免耕还田覆盖厚度一般15～
With the development of agricultural production and rural energy, there has been a great surplus of crop straw resources. These stalks accumulate on the edge of the village road and the front of the houses not only waste precious natural resources but also encroach on cultivated land, impede traffic, pollute the environment and even cause a fire. In addition to a large amount of carbon contained in crop stalks, there are nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, silicon and other nutrients, and rich in cellulose, hemicellulose, protein and other organic matter, in the soil decomposition As humus can increase soil organic carbon content, but also decomposition of polysaccharides, which is conducive to the formation of soil aggregates, improve soil fertility and improve soil tillage. Comprehensive utilization of straw is a long-term benefit of the people and the country’s work. First, direct straw straw returned without any treatment, the application of rotary tiller, grass-planting machines and other machinery directly to the pressure of straw. Second, the coverage of no-till orchard coverage of the general thickness of 15 ~
