摘要： 利用3个不同土样在实验室内进行不同浓度双氰胺(DCD)对土壤NH4-N含量变化影响的模拟试验,得出在不同土壤上施用普通碳酸氢铵(以下简称普通碳铵)添加DCD的最佳浓度。结果表明:添加DCD各处理的土壤NH4-N含量均高于只施普通碳铵的处理;在紫色土、潮土和黄壤上添加DCD抑制NH4-N损失和转化的效果分别以0.5%、0.3%、0.3%浓度为最佳。

Abstract: Through the simulating experiment that different consistence of DCD (dicyandiamid) influence on the transformation of NH4-N (ammonium nitrogen) with there different soil samples in lab, the paper gets the optimal consistence of adding the DCD while the general NH4HCO3 are used in different soils. The result indicates that the content of NH4-N in the treatments adding the DCD is more than those only using the NH4HCO3; The consistence of 0.5%, 0.3%, 0.3% is optimal respectively when the DCD is added in order to both hold up the loss and accelerate the transformation of NH4-N in Purple, Yellow Soil and Aquent.

Key words: DCD, NH4-N, GENERAL NH4HCO3, SIMULATION EXPERIMENT
