| 摘 要： | 针对风沙半干旱区风沙土易旱、易风蚀特性,开展了防风蚀技术研究。结果表明,农田防护林网主林带背风面距林缘1~6H处削弱风速约50%,随树高（H）倍数的增加效果递减;林网内扁杏//花生（间作）增强了花生裸茬抗风蚀能力,土壤防风蚀效果达90%;林网内玉米//花生（间作）玉米收获后秸秆站立（农田休闲期）玉米带完全不受风蚀,花生裸茬防风蚀效果达95%;林网内作物残体平伏覆盖防风蚀效果达120%,综合评价作物残体覆盖玉米秸秆站立的防风、保土和保水效果最佳。

| Abstract: | Aiming at the characteristics of drought-prone and wind erosion easily in aeolian soils semiarid regions,the study on anti-erosion techniques was carried out.The results indicated that wind speed reduced by 50%,which at the position of 1-6 H away from main belt leeward between farmland shelterbelt network and forest edge,and the effect decreased gradually with the increase of tree height.Flat apricot//peanut(intercropping) within the forest network enhanced the wind erosion resistance ability of peanut bare... |
