2—氯—6(三氯甲基)吡啶是一种抑制硝化细菌活动“氮肥增效剂”,使用这种增效剂与氮肥配合施用,能够抑制铵态氮的硝化作用,减少流失或在硝化过程中的损失,从而提高化肥的利用率,达到增加农作物产量的目的。根据全国化肥试验网的统一布置,一九七三年我站分别在站内的紫色石骨子土和基点、社队的老冲积黄壤上进行了棉花施用氮肥增效剂试验,现将试验结果介绍如下:
2-Chloro-6 (trichloromethyl) pyridine is a “nitrogen fertilizer synergist” that inhibits the activity of nitrobacteria. The use of this synergist in combination with nitrogen fertilizers can inhibit the nitrification of ammonium nitrogen and reduce the loss Nitrification process of loss, thereby enhancing the utilization of chemical fertilizers, to achieve the purpose of increasing crop yields. According to the unified layout of the National Fertilizer Experimental Network, in 1973, we carried out the test of applying nitrogen fertilizer synergist on cotton in the purple stone base soil and the base point of the station and the old alluvial yellow soil of the commune and brigade team respectively. The test results are introduced as follows :
