黄土丘陵沟壑区的坡耕地,冬麦收后正是暴雨季节,地面裸露,伏耕后土壤疏松,易造成严重的水土流失,小麦亩产一般只有30～40公斤。为了探索解决这一矛盾的途径,我们综合运用传统保土耕作经验和免耕技术,1982～1985年在辛店试验场进行了麦田“留茬间耕试验”。 试验田设在辛店试验场南阳峁坡地上,土壤质地为黄绵土,肥力较低,0～25厘米耕层有机质含量为0.213％,全氮为0.020％, Loess hilly and gully area of ​​slope farmland, winter wheat harvest is precisely the rainy season, the ground bare, loose soil after the tillage, easy to cause serious soil erosion, wheat mu produce generally only 30 to 40 kilograms. In order to explore ways to solve this contradiction, we comprehensively used the traditional experience of tillage farming and no-tillage technology and conducted the “stubble tillage experiment” at the Xindian Experimental Field from 1982 to 1985. The experimental field was located on the ground of Nanyang Slope of Xindian Experimental Field. The soil texture was loessial soil with low fertility. The organic matter content of 0-25 cm layer was 0.213%, the total nitrogen was 0.020%
