摘要
试验实测44株小叶黄杨的冠幅、株高和叶片生物量:其中34株用于构建模型,运用Excel 2003对叶片生物产量进行二元回归分析,构建小叶黄杨叶片生物量估测公式;另外10株用于模型验证。结果表明,小叶黄杨叶片生物量与株高相关性不显著(P>0.05);叶片生物量与冠幅相关性显著(P<0.05),叶片生物量的估测公式Y(g,叶片生物量)=156.12+7.332X(cm,冠幅;P<0.05)。
The crown breadth, plant height and leaf biomass of 44 plants of Buxus microphylla were measured in the test. 34 plants were used to establish the model among them. The binary regression analysis of leaf biomass was made by using Excel 2003 to establish the estimate formula of leaf biomass of B. microphylla. And other nine plants were used to validate the model. The results showed that the leaf biomass of B. microphylla had no significant correlation with the plant height（P0.05）. The leaf biomass showed a significant correlation with the crown breadth（P0.05）. The estimation formula of leaf biomass of B. microphylla was as follows： Y（g, leaf biomass）=156.12＋7.332X（cm, crown breadth,P0.05）.
