一种楠木轻基质容器育苗方法

A Method of Light Medium container-raising of phoebe bournei

摘要:

以浙江楠种子为试验材料,通过开展轻基质容器育苗与大田育苗试验,研究在两种育苗方法下的苗木生长特性。 结果表明,容器育苗的苗高、地径、主根长、侧根数、地下部鲜重、地上部鲜重、出 圃率均高于大田育苗,比大田育苗分别增加 15. 0% 、21. 2% 、81. 3% 、84. 6% 、88. 0% 、185. 6% 、18. 1%以上;容器育苗出圃率可达 90. 2%以上 。楠木容器育苗可促进苗 木生长量,提高苗木出圃率,保障造林成活率。

Abstract:

In this article , the seeds of phoebe chekiangensis were used as the test material, we studied seedling growth characteristics of phoebe bournei by the light medium container seedling-raising and field seedling test by two seedling methods . The results showed that the container seedlings-raising height, ground diameter , main root length, lateral root number, lower weight, ground weight and nursery rate were higher than field seedling, increasing by 15. 0% , 21. 2% , 81. 3%,84. 6%,84. 6%,88% , 185. 6% and 18. 1% respectively; the nursery yield rate of phoebe bournei container see- ding-raising can reach more than 90. 2% . Its container seedling-raising raising can promote the growth of seedlings , im- prove the rate of nursery and ensure the survival rate of afforestation .
