摘　　要：为了解不同地形对1年生关防风生物量的影响,在同一块地上分别随机选取5个5°的坡地样方和5个平地样方,开展关防风1年生苗生物量对比分析试验,结果表明:1年生关防风整株折干率平均为27.0%;不同地形幼苗干品株茎长度、根长度、总质量、根质量差异显著,根粗度差异不显著;坡地茎长度、根长度、单株总质量、根质量高于平地。环境条件基本一致,管理措施相同的情况下,有一定坡度的地形有利于关防风生长,使其生物量积累更多。In order to understand the influence of different terrains on the biomass of one-year-old Saposhnikovia divaricata,five 5°slope plots and five flat plots were randomly selected on the same plot to conduct a comparative analysis experiment on the biomass of one-year-old Saposhnikovia divaricata seedlings.Result shows that the average stem-breaking rate of the whole plant in the one-year-old Saposhnikovia divaricata is 27.0%;the stem length,root length,total weight per plant&root quality of seedlings in different terrains are significantly different,but the root thickness is not significant;root length,total mass per plant and root mass are higher than those on flat ground.The environmental conditions are basically the same,and under the same management measures,a certain slope is conducive to the growth of wind protection and more biomass accumulation.
