摘要
农作物的生产离不开化肥的施用,合理的使用化肥可以提高土壤中有机质的含量,增加土壤的养分,进而减少病虫害并提高农作物的产量。反之,化肥使用过少或过量,都会导致土壤中有机成分的含量发生巨大的变化,轻则引起病虫害,影响农作物的生长与产量,严重时危害生态环境,对居民的身体健康产生不良影响。本文以青海省西宁市为例,分析了过量施用化肥带来的危害,以及部分解决措施。
The production of crops can not be separated from the application of chemical fertilizers,the rational use of chemical fertilizers can improve the content of organic matter in soil,increase soil nutrients,and then reduce pests and diseases and increase crop yields. On the other hand,too little or too much chemical fertilizer will lead to great changes in the content of organic components in the soil,which will cause diseases and insect pests,affect the growth and yield of crops,and endanger the ecological environment seriously.And have a bad effect on the health of the residents. Taking Xining City of Qinghai Province as an example,this paper analyzes the harm caused by excessive application of chemical fertilizer and some measures to solve it.
