农业生产中减施化肥措施的研究进展

Advances in Reduction Measures of Chemical Fertilizer Application in Agricultural Production

在农业生产中,化肥对我国作物产量提高起着非常重要的作用,但长期过量和单一施用化肥造成的土壤板结、地力下降、病虫害多发、生态环境污染、作物产质量不稳、危害人畜健康及不利农业生产可持续发展等严重问题已不容忽视。为有效推动我国化肥施用零增长,从增施有机肥、合理施用生物菌肥及调整农业栽培措施等方面对我国农业生产减施化肥措施的研究进展进行归纳总结,并对其今后的发展方向进行展望。

In agricultural production chemical fertilizer plays a very important role in enhancing crop yield,while long-term excessive single application of chemical fertilizer causes severe problems such as soil hardening,soil fertility decreasing,frequent occurrence of diseases and insect pests,eco-environment pollution,unstable crop yield,harm to human and livestock health and bad for sustainable development of agricultural production,which can not be ignored.In order to effectively limit the application of chemical fertilizers,the authors summarize the advances in reduction measures of chemical fertilizer application in agricultural production from aspects of increasing organic fertilizer application,applying bio-fertilizer rationally and adjusting agricultural cultivation measures,and finally proposes the development direction in the future.
