摘要
本文通过对初果期酥梨树体生物学因素的调查测定,确定出酥梨树干周与产量构成的枝条生长,叶片生长,花果发育,树体结构和产量等19个因素的相关系数。通过逐步回归分析确定出干周与产量构成的19个因素的回归关系和最佳树干干周范围65～75cm。
In this paper, the correlativity and regression between the trunk
circumference and some biological factors such as branch number/per tree,
leaf-area/per tree, flower number/per tree, production/per tree was
studied in Su pear tree on the orchard of Chang Kang River in middle of
Shanxi Province. The results indicates that the correlativity is significant,
that, regressed progressivily, the regression model is Y=ax^2+bx+c, and
that the optimum trunk circumference is 65-75cm in this tree.
