一、概述容器育苗已经在我国南北各省逐渐发展起来。温室容器育苗可以人为控制环境条件,缩短育苗周期,苗木规格化,便于实现工厂化育苗。用容器苗造林具有成活率高,没有缓苗期,可以延长造林季节,适合造林困难地区等优点,因而容器育苗和用容器苗造林已引起广大林业工作者的重视。但在容器苗的试验和生产中,苗木 First, an overview Container seedling has been gradually developed in our provinces north and south provinces. Greenhouse container seedlings can artificially control environmental conditions, shorten the nursery cycle, seedling standardized, easy to achieve factory nursery. Container seedling afforestation has the advantages of high survival rate, no rejuvenation period, can extend the reforestation season, suitable for afforestation difficult areas, container seedling and container seedling afforestation has attracted the attention of the majority of forestry workers. But in the container seedling test and production, seedlings
