A Summary of Study on the Fertilizer Applying and Its Environmental Effects

化学肥料是人类提高农作物产量的重要生产资料。随着农作物需求的增加,世界化肥的用量不断增长。同时,肥料利用率低及由此引起的一系列环境问题也越来越引起人们的注意,各国科研人员对此做了大量研究,也取得了一些重要进展。就我国化肥施用的历史与现状,化肥的环境效应及其机理,化肥污染的预防与治理以及环保型的控释肥等方面进行了较系统地综述。

The amount of chemical fertilizers applied is increasing to increase the yields of cropsBut utilizing rations of fertilizers are very low, which causes the falling of environmental quality So researchers all over the world have been done and are doing research on this problemsIn this article, the work on the historical and current situation of fertilizer applying, the evnironmental effects of fertilizer and its mechanism,the controlof fertilizer caused pollution and a new type of fertilizer,control-released fertilizer are summarized systematically
