摘　　要：通过５年的定位试验，初步探索出铜仁主要旱耕地两种不同轮作方式的培肥措施。提出了在两种轮作方式中利用秸秆直接还田和在冬季作物中套种箭舌碗豆和苕子有利于耕地培肥，以达到用养结合的目的。分析了不同处理对土壤农化性质和作物产量的影响，论证了这一培肥技术的效应。The measures were found for maintenance of soil fertility in two rotation system on dry land in Tong ren region through 5 years study.Ploughing the crop stubble or straw into soil or intercropping green manure crops Vicia sativa L.or Vicia cracca was favourable for maintaining soil fertility and provided nutrients both for a current crop and for later ones,these effectiveness was proved by analysis of crop yield
