目的:研究多花黄精种子育苗的最佳播种期、播种方式、播种深度、播种量和苗床覆盖物。方法:进行不同播种期,播种方式,播种深度、播种量和苗床覆盖物L_9(3~4)正交的育苗试验;比较不同处理的出苗数、苗高、叶长宽乘积、相对叶绿素含量和根冠比,评价育苗质量。结果:不同播种期的苗高、相对叶绿素含量和出苗数有显著性差异;次年4月底育苗质量最差,次年2月底育苗质量较好。不同播种方式的出苗数、苗高、叶长宽乘积和相对叶绿素含量没有显著性差异;总体上撒播育苗质量较好。L_9(3~4)正交处理的出苗数、苗高、叶长宽乘积、相对叶绿素含量和根冠比有极显著性差异;苗床覆盖物对育苗质量影响最大。结论:多花黄精种子最佳播种期和方式是次年2月底和撒播,最佳播种深度、播种量、苗床覆盖物分别是1.5 cm、29.4 g/m~2和遮阳网。
Objective: To study the optimum sowing date, sowing method, sowing depth, seeding rate and seedbed cover of Polygonatum spp. Seedling. Methods: Seedlings were inoculated at different sowing dates, sowing methods, sowing depths, sowing rates and seedling bed coverings L_9 (3-4) orthogonal to each other. Seedling numbers, seedling height, leaf length and width, relative chlorophyll content Ratio, evaluation of nursery quality. Results: There were significant differences in seedling height, relative chlorophyll content and seedling emergence at different sowing dates. The quality of seedling nursery was the worst at the end of April the following year, and the quality of seedling nursery was better at the end of February next year. There was no significant difference in seedling number, seedling height, leaf length, width and relative chlorophyll content in different sowing methods. Generally, sowing seedling quality was better. The seedlings emergence, seedling height, leaf length and width, relative chlorophyll content and root / shoot ratio of L_9 (3 ~ 4) orthogonal treatment had very significant difference. Seedling cover had the most significant effect on seedling quality. CONCLUSION: The optimal sowing date and method of Phellinus igniarius seeds are at the end of February and sowing in the following year. The best sowing depth, seeding rate and seedbed coverage are 1.5 cm, 29.4 g / m ~ 2 and shading net respectively.
