| Abstract: | A study was conducted to discuss the spatial distribution of root system of jujube trees in jujube-crop intercropping system in Aksu by the layered digging method,in order to provide a theoretical basis for the establishment of root water uptake model for jujube trees,the analysis of ecological characteristics of water,and the determination of application area.Results showed that,in the vertical direction,in the jujube-wheat intercropping system,the jujube roots distributed in the 0-80cm soil layer,accounti... |
