摘要:
氯化铵作为小麦的氮肥施用,营养平衡时,其肥效与硫铵相近;小麦籽粒粗蛋白总量、面筋含量、蛋白质各组分含量亦差异不大。若麦体营养不平衡时,则氯铵肥效降低、吸氯量增加,氯毒害加重,明显影响小麦产量、品质及生长发育,且降低麦株对N.P.K的累积量。施入土壤中的氯化铵,约5-10%的氯为小麦吸收,约5%残留在耕层土壤中,余则在当季作物期间被淋洗。小麦吸收的氯主要分布在叶片和茎杆中,约占95%,很少向穗部运转。

In the regions of yellow brown earth, where the soil mainly lack ofphosphorous and nitrogen, the status of nutrients equilibration is NP>NPK>NK. Whenwheat nutrients are equilibrated, the fertilizer efficiency of ammonium chloride is about thesame as ammon
