秸秆是农作物的重要副产品,是工农业生产的重要资源。大量的农作物秸秆被废弃,甚至被焚烧,既浪费了资源,又污染了环境。因此,如何利用秸秆已经成为农业生产资源开发和环境保护的新焦点。就目前的技术水平而言,秸秆还田是最主要、最有效的应用途径:秸秆中含有大量的有机质、氮磷钾和微量元素,是农业生产重要的有机肥源之一。通过秸秆还田补充和平衡土壤养分、改良土壤,提高资源利用率,对农业节本增效,提高耕地基础地力、实现农业 Straw is an important byproduct of crops and is an important resource for industrial and agricultural production. A large amount of crop stalks have been abandoned or even burned, wasting resources and polluting the environment. Therefore, how to use straw has become the new focus of agricultural production resources development and environmental protection. As far as the current technological level is concerned, straw is the most important and effective way of application. Straw contains a large amount of organic matter, nitrogen, phosphorus and potassium and trace elements and is one of the important organic fertilizer sources for agricultural production. Through straw to replenish and balance soil nutrients, improve the soil, improve resource utilization, the efficiency of agriculture section, improve the foundation of farmland, agriculture
