Abstract

To provide the essential theoretic bases for applying the planting pattern of intercropping trees with medicinal plant in the west part of China , This paper carried through a more embedded study on the illumination characters and its effect on the growth of medicinal plants in trees and medicinal plants intercropping system by setting different popular row spacing grads .The results were as follows:the light intensity daily change on the middle measure spot between the popular rows was a curve with one peak , it was same as the contrast , but the value of light intensity on the peak was lower than the contrast .The light intensity daily change on the measure spot east to the popular rows and west to the popular rows were symmetrical , the former appeared peak in the morning , the latter in the afternoon .The daily average light intensity on the middle measure spot was higher than that on the other measure spots .The daily average light intensity between popular rows decreased with the popular row spacing decreasing .The height growth of Glycyrrhiza uralensis , Platycodon grandiflorum and Pinellia pedatisecta were different when they intercropped with Populus tomentosa .With the popular row spacing decreasing , the fast height growth rate of Glycyrrhiza uralensis decreased from 1.11 cmd-1 on the contrast to 0.45 cmd-1 on the row spacing 3m , the growth rate change of Platycodon grandiflorum was not serious , on the contrary , the fast height growth rate of Pinelliapedatisecta increased from 0.2 cmd-1 on the contrast to 0.37 cmd-1 on the row spacing 3 m .These results indicated that Platycodon grandiflorum .and Pinellia pedatisecta can adapt to environment of intercropping , these two species can be used to intercrop with trees .
