摘　　要：基于豫东沙区传统农田防护林,生产力低下,防护效能差,胁地严重等一系列问题,进行了低竞争树种筛选、错位栽植、设置根障、修枝控冠等调控措施。经过连续5 a的试验研究,发现防护林调控技术,可以减少胁地,显著提高胁地减产区作物产量。小麦、玉米、花生、大豆、油菜等主要农物增产率分别达到10.01%、6.52%、7.01%、5.06%、11.23%。Based on a series of problems of the traditional farmland shelterbelt in the eastern sandy area of Henan Province,such as low productivity,poor protection efficiency and serious soil coercing,the selection of low competitive tree species,staggered planting,setting up root barriers,pruning and controlling crown were carried out.After five years of experimental study,it was found that the protective forest regulation technology could reduce the soil coerced and significantly improve the crop yield in the soil coerced area.the yield of wheat,maize,peanut,soybean and rape increased by 10.01%,6.52%,7.01%,5.06%and 11.23%respectively.
