通过对甘肃省中部干旱区47个柠条样地生物量结构特征分析,选以丛生物量为因变量,丛高、冠幅为自变量的二元线性回归方程W=-1.7537+0.9637H+1.7144C 为估算该区丛生物量的有效模型,并依该模型编制生物量表。为保护柠条资源及提高其生产力,提出了合理的平茬技术措施。 Based on the analysis of biomass characteristics of 47 species of Caragana korshinskii in central arid region of Gansu Province, a binary linear regression equation was established, in which the mass of biomass was the dependent variable, the height of the cluster and the amplitude of the crown as the independent variable W = -1.7537 + 0.9637H + 1.7144 C is an effective model to estimate the clump biomass in this area, and the biomass scale is compiled according to the model. In order to protect the resources of Carambola and improve its productivity, reasonable technical measures of stubble cutting were put forward.
