【Abstract】 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.更多还原
