Abstract:

By sampling in the protected area within the enclosure and abandoned land outside the enclosure in the Longjing Nature Reserve,the modules of wild soybean were studied and the morphological characteristics and biomass of modules were analyzed.Results showed that morphological indexes and biomass of the wild soybean modules in the abandoned land were significantly higher than those in the protected area.There were primary branches in the protected area whereas there were secondary branches in the abandoned land.In the abandoned land,the length of main stem,primary branches and total stems were 1.4,4.6,2.6 times;the number of primary branches,leaves on primary branches and total leaves were 2.8,1.4,4.0 and 2.5 times of those in the protected area,respectively.While，in the protected area,the modules biomass of root,total stems,total leaves and whole plant accounted for 75.0,25.7,23.0 and 25.9 percent of those in the abandoned land,respectively.Therefore,it was deduced that moderate interference was benefit for the growth of the wild soybean.The total biomass of 29 samples increased with the increases of the plant height,total length of stem and total number of leaves,which showed a linear regression function(y=a+bx)variation.The biomass of the main stem,branches,total stems,leaves on main stem,leaves on branches,total leaves all increased with the increases of the total biomass,which also showed a linear regression function(y=a+bx)variation.
