根据近几年的调查,当前在农业生产中氮肥施用上的一个突出问题是,单位面积施用量日益增高,但作物吸收利用率低。利用率低的原因很多,一般认为大部分通过硝态氮的渗滤和反硝化作用而损失掉了。因此,如何抑制硝化微生物的活动,减少氮肥流失,已成为一个重要的研究课题。 2-氯-6-(三氯甲基)吡啶〔即N-Serve〕是国外应用较早的一种硝化抑制剂,1969年由旅大轻化工所试制成功。为探讨添加和不添加该剂对主要作物(除豆科外)的增产
According to recent surveys, one of the prominent problems in the current nitrogen fertilizer application in agricultural production is the increasing application rate per unit area, but the low utilization rate of crops. There are many reasons for low utilization, and it is generally believed that most of them are lost through the diafiltration and denitrification of nitrate nitrogen. Therefore, how to inhibit the activity of nitrifying microorganisms and reduce the loss of nitrogen fertilizer has become an important research topic. 2-chloro-6- (trichloromethyl) pyridine [N-Serve] is a foreign application of a nitrification inhibitor earlier, in 1969 by the Luda Light and Chemical trial success. To explore the increase of main crops (except legumes) with and without the addition of this agent
