    摘要:

    科学减施化肥用量,合理配施有机肥对土壤肥力提升、农产品增质和减轻面源污染有着重要的意义。我国农业有机废弃物资源丰富,有机养分总量达到约 7 519.5万 t,其中 N、P 2O5、K2O养分总量分别为 3 096.3万、1 174.1万、3 249.1万 t,但是目前资源利用率不足 40%,不仅造成优良有机养分资源的浪费,同时带来环境污染风险的问题。如何高效利用有机肥资源是我国目前亟需解决的问题。本文总结有机肥相关文献和他人研究结果,综述了我国有机肥资源数量、利用现状,针对施用的问题,对产业发展提出了一些建议。

    Abstract:

    Scientifically reducing the amount of chemical fertilizers and rational application of organic fertilizers are of greatsignificance for improving soil fertility,increasing crop quality and efficiency of agriculturalproducts,and alleviating non -point source pollution.China has abundant resources of agricultural organic fertilizers.It is estimated that total organicnutrient(nitrogen +phosphorus+potassium)resource in China amounts to more than 75.195 milliont,including30.96311.741 and 32.491 million t ofN,P 2O5 and K2O,respectively.However,the current utilization rate of organic fertilizerresources is less than40%.It causes not only the waste of good organic nutrientresources,but also environmental pollutionproblems.It becomes an urgent problem to efficiently use organic fertilizerresources.Based on the relevant literatures andstudies on organicfertilizer,we reviewed the amount of organic fertilizerresources,current situation and problems of organicfertilizer application inChina,and gave some suggestions for industrial development.
