有些城市近郊的农民,经常利用农闲时期,把城市的垃圾运回做基肥,其实这样做是不科学的。因为垃圾中的有效成分没有经过发酵腐熟,作物不能吸收。垃圾中还有很多作物不能吸收利用的杂物,不清除出去会影响土壤肥力和作物生长.要合理利用垃圾,应先把垃圾中的石块、碎铁丝、铁块、塑料片、玻璃渣等废物一起清除,然后把垃圾堆入一个坑中,再适当加入一些秸秆、厩肥、水,经过一个冬 In some cities, peasants in suburbs often make use of the slack season to transport the city’s garbage back to basal fertilizer. Actually, this is unscientific. Because the active ingredients in the trash have not been fermented and matured, the crops can not be absorbed. There are many garbage can not absorb the use of debris, do not clear out will affect the soil fertility and crop growth.
