摘　　要：采用田间试验的方法 ,研究杨树幼林与小麦间作系统中 ,设置根障对小麦生长和产量的影响。结果表明 ,在集约经营的条件下 ,根障使小麦地上部分生物量积累增加 ,并且叶绿素含量相对下降 9.2 % ,产量提高 3.3% ;在水肥缺乏的情况下 ,根障的存在使小麦的生物量积累降低 ,产量下降 3.2 %The effect of root barrier on wheat growth and yield was studied in the system of poplar young growth intercropping with wheat by means of farm testing. The results demonstrated that the root barrier could add wheat above ground biomass, and decrease its leaf chlorophyll content 9.2% and increase yield 3.3% in the intensity management; but it would bring adverse effect to wheat above ground biomass and decrease yield by 3.2% in the condition of lack of irrigation and fertilization.
