城市垃圾一直是采取烧毁、掩埋或抛入水等方法来处理。近年来,城市垃圾的利用已成为越来越重要的问题。堆制是城市垃圾农用的处理方法之一。农田施用垃圾堆肥因它可以提供各种养分和作为土壤改良剂,因此可以提高土壤的生产力。但是,如果堆肥腐熟不够,有时也会对作物产生严重危害。 Municipal waste has always been burned, buried or thrown into the water and other methods to deal with. In recent years, the utilization of urban garbage has become an increasingly important issue. Stacking is one of the treatment methods of urban garbage farming. Composting of farmland with trash can increase soil productivity because it provides a variety of nutrients and acts as a soil conditioner. However, if compost is not compounded enough, it sometimes can be a serious crop hazard.
