铅笔柏小规格容器袋限根育苗技术

Seedling Technology of Restriction Roots of Sabina virginiana with Small-size Container Bag

针对铅笔柏容器苗搬运不便和起苗断根造成的缓苗现象,试验结果表明,采用小规格塑料容器袋和限根育苗措施,在生产上是可行的,实生苗1年半生即可出圃造林,并发现铅笔柏幼苗长势变异大,对环境条件反应敏感,建议在育苗生产中应加强规范化标准管理,以便苗木生长健壮整齐,提高出苗率。

According to problems in the following： it was inconvenient to carry container seedlings of Sabina vir-giniana and phenomena of restoration seedlings because of broken root while moving seedlings from the nursery for transplantation,experimental results showed that adopting the method of small-size plastic container bags and nursery measures of restriction root,which was feasible in the production,seedlings half a year could come out nursery for af-forestation,meanwhile,variation of seedling growth of Sabina virginiana was great,and action to environmental condi-tions was sensitive,seedling production in the proposed standards should be strengthened standardized management for growth strong and tidy of seedling,and increased seedling emergence.
