| 摘 要： | 分析了植物篱桑和地埂桑的年片叶量（Y）、桑树的有效条数（NB）、平均有效条长（LB）、条粗（DB）、平均每m条着叶数（NL）等数据，研究了年片叶量与其它各因子之间的相关关系。结果表明，植物篱桑的年片叶量与平均有效条长和条粗极显著相关；地埂桑的Y与有效条长、条粗极显著相关，与每m条着叶数显著相关；将两种种植模式下的桑树作为一个整体，则Y与NB、LB、DB、NL等因子相关极显著。建立了植物篱桑、地埂桑和整体的Y与显著相关DB、NL等因子相关极显著。建立了植物篱桑、地埂桑和整体的Y与显著相关因子之间的最优数学回归模型。文章同时指出，植物篱桑和地埂桑的树势间存在的极显著差异导致了桑叶产量之间的差异，对产生这些差异的原因也作了讨论。

| Abstract: | Based on the data of Mulberry intercropped in contour hedgerow (MIH) and Mulberry planted on land riser (MLR) about annual leaf yield (Y), number of effective branches (NB), average length of effective branches (LB) and diameter of branches (DB), average number of leaves grown on m branches (NL), this paper analyzed the relationship between Y and the other. This paper established the optimal mathematical regression model between Y of MLR, MIH and the whole of two planting modes and the factors having significant correlation to Y. |
