本世纪全球最大的挑战之一是如何解决日益增长的人口和不断萎缩的耕地面积之间的矛盾,同时还要维系土壤地力和保护环境。基于全球多个长期定位实验站的数据显示施用有机肥是解决以上诸多问题的有效途径之一。但是,有别于化肥,有机肥料中的养分不能直接被作物所利用,需要微生物的帮助。中国科学院封丘农业生态实验站长期养分定位试验揭示施用有机肥的前 One of the world’s biggest challenges of this century is how to deal with the conflict between a growing population and a shrinking arable land while maintaining soil fertility and protecting the environment. Based on data from several long-term global pilot stations in the world, organic fertilizer application is one of the effective ways to solve these problems. However, unlike fertilizers, nutrients in organic fertilizers can not be used directly by crops and require the help of microorganisms. Long-term nutrient location test at Fengqiu Agro-Ecological Experimental Station, Chinese Academy of Sciences reveals that before applying organic manure
