摘　　要：林草、林药间作,林木为牧草和药材提供蔽阴条件,同时,林下间作牧草、药材,有利于改良林地土壤理化性质,增加肥力,促进林木生长。采取林草、林药间作的杨树,经精耕细作,与未采取林草、林药杨树对比,平均每年胸径增加了78.31%,高生长增加了186.58%。因此,在辽西北地区林草、林药间作是可推广的配置模式。奇可利、蒙古冰草、羊草是适于本地区种植的优良牧草;林间种植牧草、药材可获得较好经济效益。Trees provide shelter for pasture herbs under intercropping forest,pasture herbs.At the same time, understory intercropping will help improve the physical chemical properties of forest soil,increasing soil fertility promoting tree growth.Intercrops（intercrop vs.no intercrop） pasture herbs on poplar with intensive cultivation were tested;average annual DBH height growth increase by 78.31% 186.58 %,respectively.Thus,popularization for intercropping forest,pasture herbs should be taken in the northwestern area of Liaoning.Cichorium intybus cv.Barckoria,Agropyron mongolicum keng Leymus chinensis are all suitable for planting in local area.Pasture herbs intercropping in forest can achieve optimal economic efficiency.
