摘　　要：本文以河套灌区的农田防护林为研究对象,通过对所选农田防护林背风面距林带不同距离处小麦株高、穗长、每穗实粒数、千粒重和产量的测定,研究了农田防护林的增产效益。研究表明,农田防护林能够增加小麦的产量,林网内小麦的平均株高、穗长、每穗实粒数、千粒重和产量均高于对照麦田。通过对河套灌区农田防护林对小麦增产效益的研究,为河套灌区农田防护林的更新改造提供科学依据。Based on farmland shelter forest in Hetao Area, by determining the plant height, spike length, filled grain number per spike, 1000- grain weight and yield of wheat in the different distance of farmland shelter forest leeward side, this article studied the yield increase benefit of farmland shelter forest. The research indicated that the farmland shelter forest can increase the wheat yield, the wheat＇s average plant height, spike length, filled grain number per spike, 1000 - grain weight and yield in the forest network are higher than the comparison wheat field. It provided the scientific basis for the shelter forest＇s renewal transformation in Hetao irrigation area by researching the wheat yield increase benefit under the farmland shelter forest in Hetao area.
