摘要：

通过田间试验，研究双氰胺(DCD)对块茎类蔬菜马铃薯各个生长时期农田土壤铵态氮、硝态氮转化的影响。结果表明：加入双氰胺后，土壤中铵态氮含量均显著提高（p＜0.05），硝态氮含量显著降低（p＜0.05）。

Abstract:

The field experiment studies the effects of Dicyandiamide on the of Ammonium-N and Nitrate-N transformation in the soil of potato in each growth stage. The experimenting potato was middle and late variety“KexinⅠ”;the seed manure were:(NH4)2SO4+Ca(H2PO4)2+DCD, (NH4)2SO4 +Ca(H2PO4)2, Ca(NO3)2+Ca(H2PO4)2,Ca(H2PO4)2.The result shows that the content of Ammonium-N increased While that of nitrate-N decreased significantly（p＜0.05） when applying Dicyandiamide.
