摘要: 以内蒙古武川地区耕地为试验地,对燕麦不同留茬高度的试验田进行土壤水分、土壤养分的监测。结果表明:与传统耕作相比,燕麦田留茬能有效地增加土壤水分和养分含量,燕麦留茬20cm免耕播种的有机质和全氮含量表现最高,0~5cm深度土壤相对含水量随秸秆留茬高度的增加而增高。

Abstract: Wuchuan area of West-to-east Mountain North was selected to study the affection of different residual stubble height of oats on soil moisture and nutrient content in the experimental field.The study showed that residual stubble effectively increased soil moisture and nutrient content and that organic matter and total nitrogen content were higher than other treatments for residual stubble height of 20cm.The study also showed that soil moisture content increased along with the increasing of the stubble height.
