摘要:

开展云南萝芙木苗木类型和株行距对比种植试验,研究苗木类型和株行距对其生长和产量的影响。结果表明:实生苗和扦插苗间茎、叶和根生长表现差异不显著(P>0.05),考虑到扦插苗具有易于大量生产、生长均一等特点,应用扦插苗造林更优;不同株行距处理间云南萝芙木茎、叶和根生长表现差异显著(P<0.05),其中0.4 m×1.0 m株行距处理的茎叶和根的产量均最高。

关键词: 云南萝芙木, 苗木类型, 株行距配置, 生长表现, 根产量

Abstract:

Planting trials of seedling types and spacing were conducted for RauwoIfia yunnanensis,and effects of seedling types and spacing on its growth and yield were investigated.The results showed that cuttings should be applied in the practice rather than seedling of R.yunnanensis due to their easy cultivation and few individual variation,although significant difference in growth and yield was absent between them in the present study.There were significant differences in growth and yield of R.yunnanensis among six spacing treatments,and the yield of stems and leaves as well as roots performed the best for spacing 0.4 m×1.0 m.

Key words: RauwoIfia yunnanensis, seedling types, spacing, growth performance, root yield
