摘　　要：通过调查中华常春藤的生境和测量茎的生长情况,总结了中华常春藤的种植特点和分枝方式,同时利用SPSS软件的回归分析建立回归模型,并根据建立的模型用Excel软件绘制坐标图。结果表明:中华常春藤主枝生长完毕所需的有效积温为2 718.34℃/d;茎伸长量随有效积温延续的变化呈"S"形曲线,而茎伸长速度变化趋于钟罩型单峰曲线。再利用此结果估算出:在理想的生长条件下采用三角形定植方式定植中华常春藤为宜,并且植株与植株之间的最佳定植密度为510 mm×510 mm。During the growth period of the hedera nepalensis var. sinensis, surveying the habitat, measuring the growth situation of stem, the character of planting and the pattern of branching were summed up. At the same time, It used SPSS11. 5 for setting up the regressive equation, and then the curves were drawn on the basis of them by Microsoft Office Excel 2003. The results indicated that the effective accumulation temperature was 2 718. 34℃/d when the main stemof hedera nepalensis var. sinensis finished the growth. The elongation length of main stem to the effective accumulation temperature was ＂S＂ curve, and the elongation speed of the main stem appears Lampshade-single peak curve along with the effective accumulation temperature. The planting of hedera nepalensis var. sinensis to field was based on this curve, and the results were as follows： the hedera nepalensis var. sinensis was used the triangle planting to field, and the best planting density was 510 min× 510 mm in the ideal growing situation.
