红椆播种苗移栽容器育苗技术研究

The research of container seedling cultivation technology on Cyclobalanopsis gilva

为提高红椆苗木质量和造林成活率,对红椆2年生直播苗和2年生撒播苗移栽容器苗苗木质量进行对比试验,同时采用不同规格容器和遮荫处理对1年生撒播苗移栽到容器后苗木的成活率和生长量进行比较试验。结果表明:容器育苗可显著提高红椆苗苗高、地径、主根长、地上部分干重、地下部分干重;容器规格对移栽后苗木成活率影响不显著,但对苗木生长有显著影响;采用80%遮阳网遮荫,容器苗成活率较高,苗木高生长也显著增加,但苗木地径生长与60%遮阳网遮荫处理的苗木差异不显著。

In order to improve the seedlings quality and survival rate of Cyclobalanopsis gilva,taking the biennial seed-lings and container seedling of C.gilva for contrast test were analyzed,and the container seedlings for survival rate and growth volume were analyzed by using different seedling container size and shade treatment.The results were showed that the container seedlings could significantly improve the C.gilva plant height,ground diameter,root length,dry weight of above ground and underground parts of dry weight;different seedling container size had no significant effect on seedling survival rate,but the container size had a significant effect on seedling growth;with 80%shade network,the survival rate and height growth of container seedling were increased,but the diameter growth of container seedling had no significant difference compared with 60% shade net treatment.
