摘要: 根据山东夏津县黄河故道风沙地3年的杏粮棉草间作试验表明:间作可改善沙地生态环境。间作绿肥和豆科作物能改良土壤,促进杏树生长,间作物留茬或割覆可减少风蚀,间作还可提高土地利用率。因此,杏粮棉草间作是适合沙区发展的立体农业模式。

Abstract: The interplant experiment of apricot, cotton and grass conducted on the blown sand land in the ancient course of the Yellow River on Xiajing ,Shandong Province show that the interplant can improve the ecological environment, expecially the interplant of green manure crops and leguminous plants not only can improve soil fertility but also can promote the growth of apricot trees. And the stubble mulch of interrow corps can reduce the wind erosion. Therefore, the interplant of apricot,cotton and grass is a stereocopic planting pattern suitsble for the blown sand land.
