摘要/Abstract

摘要： 在旱作区进行绿肥作物与马铃薯轮作研究,结果表明,苕子和豌豆增施N、P化肥均有显著的增产效果,增产可达13.0%～36.0%。箭筈碗豆增产效果好于蒙苕一号。尽管马铃薯平衡施肥的茬口后效最好,但与绿肥作物各施磷酸二铵处理之间没有显著差异。毛叶苕子和箭筈碗豆两种绿肥作物茬口对后茬马铃薯产量基本没有影响。绿肥后茬减少施N量30%,减产不明显,说明在干旱地区种植绿肥后可以减少N肥用量30%。

Abstract: The study on the rotate cropping of potato and green manure was carried out in the dry land in the North foot of Yinshan Mountain.The results showed that the yield of hairy vetch and common vetch were increased by 13%-36.0% after applying N and P fertilizer and the effect was larger on the common vetch yield.The residual effect of balanced fertilizer on the potato yield is as good as in the treatment of applying DAP in the green manure.The effect of green manure on the yield of potato was not obvious.When the N fertilizer application was deceased 30% the yield of potato was not decreased significantly.So the N fertilizer applying can be decreased by 30% after green manure cropping.
