| 摘 要： | 试验设置了胡枝子林分0—7次刈割频度，随着刈割频度的增大，胡枝子根系质量、主根直径、根瘤个数及根瘤大小都逐渐降低；根的可溶性糖含量也随着刈割频度的增大而下降，地上生物量也呈下降趋势。1a之中刈割3次，每6周刈割1次的胡枝子，可得到最大超补偿生长，并获得最大地上生物量。

| Abstract: | Cutting frequency of Lespedeza bicolar stand was set up for 0-7 times.The quality of root,diameter of main root,the number and size of nodule of Lespedeza bicolar decrease with the increasing of cutting frequency;soluble sugar content of root decrease with the increasing of cutting frequency.Aboveground biomass shows downtrend.Cutting 3 times a year and cutting 1 time six weeks for Lespedeza bicolor,the most largest aboveground biomass and supercompensation growth can be obtained. |
