摘要: 【目的】研究光照、密度、氮、磷对柳条省藤幼苗株高、地径、叶面积、生物量及保存率的影响,探讨适合柳条省藤幼苗生长的最佳环境条件,为苗圃地育苗提供参考。【方法】采用L16(45)正交试验设计,比较不同处理组合下柳条省藤幼苗(120、240、360 d)株高、地径、叶面积、生物量、保存率等指标变化规律,并运用主成分分析和隶属函数找出最佳的处理组合。【结果】幼苗不同生长指标间存在较强的相关关系,第一主成分贡献率较高(3个生长阶段累积方差贡献率分别为80.596%、76.278%和76.691%),用第一主成分(生长特性)代表幼苗的综合生长情况进行不同处理组合间的比较分析,分析结果可靠。柳条省藤幼苗在3个生长阶段,最佳处理组合中幼苗株高、地径均显著增加,幼苗保存率保持80%以上;最差处理组合中幼苗株高、地径差异不显著,幼苗保存率显著降低,在360 d时仅为14%。【结论】试验发现4号处理组合隶属值最大(4.619),即柳条省藤幼苗在光照强度80%~85%、密度25 cm×25 cm、氮肥90 g/m2、磷肥80 g/m2环境下生长最好。

Abstract: 【Objective】 We aimed to study the suitable growth conditions for Calamus viminalis seedlings by assessing the effects of light intensity, seedling density, nitrogen and phosphorus content on the growth indexes, including plant height, ground diameter, the area and biomass of leaf, and percentage of seedling survival of C. viminalis seedlings. Our study will pave the way for the artificial cultivation of C. viminalis. 【Method】 Orthogonal test of L16(45) was performed. The plant height, ground diameter, the area and biomass of leaves, and percentage of seedling survival rate of C. viminalis seedlings at different developing stages(120, 240, 360 d) were measured and statistically analyzed. And the optimal growth condition was obtained by the membership function analysis and principal component analysis. 【Result】 Significant correlations were found between different growth indexes. The first component (growth characteristic) was the chief contributor, the cumulative variance proportions of which on different developing stages (120, 240 and 360 d) were 80.596%, 76.278% and 76.691%, respectively. Therefore, the first component of growth characteristic was regarded as summary growth situation of C. viminalis seedlings for comparatively analyzing the treatment groups. The growth characteristics, including plant height and ground diameter, of optimum cultivating group were significantly increased and the percentage of seedling survival was over 80%. On the contrary, the plant height and ground diameter of worst cultivating group, with survival percentage as low as 14% at the growth stage of 360 d, had no difference with CK. 【Conclusion】 The membership function value of group 4 was the maximum of 4.619, indicating that the optimal growth condition of C. viminalis seedlings was the light intensity of 80%~85%, seedling density of 25 cm×25 cm, nitrogen content of 90 g/m2 and phosphorus content of 80 g/m2.
