遮荫强度对南方红豆杉苗木质量影响的研究

Effects of Shading Degree on Seedling Quality of Taxux chinenwsis var. mairei

采取不同遮荫强度及时间,对南方红豆杉苗木进行培育试验。结果表明:遮荫50%,夏季和早秋全遮荫6 h,对培育3～4年生苗木有利;遮荫度70%～90%,且在夏季和早秋全天遮荫,对培育1年生苗木有利;遮荫70%,且在夏季和早秋全天遮荫,对培育2年生苗木效果显著。

Using different shading degrees and lasting time to conduct cultural experiments of Taxux chinenwsis var.mairei,the results showed that shading 6 hours in the summer and early autumn was favorable to 3~4 year-old seedlings;shade degree of 70%~90% and shading full-time in the summer and early autumn was favorable to one-year-old seedlings;shading degree of 70% and shading full-time in the summer and early autumn was favorable to biennial seedlings significantly.According to these results,the seeding cultivation methods for Taxux chinenwsis var.mairei were summarized.
