摘要
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。
Forty-seven plots were sampled for analysis of the biomass structural features of littleleaf peashrub, Caragana microphylla, of Gansu Province . Results show that the regre ssion equation w = -1 .753 7 + 0.9637H + 1 .7144C is an effective model of biomass estimate, where w stands for the biomass of a clump of the plant, H stands for the clump height and C stands for the crown diameter. It the light of the model, a biomass table was compiled. Furthermore, in order to protect the resource of this plant and improve productivity, the rational tending technique is put forward.
