容器育苗是培育壮苗、提高造林质量、实现林木速生优质丰产的一项重要技术。据报道,七十年代末期,瑞典的容器育苗数量就占苗木总产量的59%,芬兰占29%,加拿大占34.6%,美国占1 7%,巴西、泰国、尼日利亚等国高达70—90%,已有取代裸根育苗的趋势。在发达的国家,容器育苗已朝着专业化、工厂化、商业化的方向发展。美国最大的林业综合企业惠好公司,在西雅图育苗基地建有总面积达1.1万平方米的自动调温和喷灌系统的温室,进行工厂化容器育苗,每年可生产标准质量的云杉、冷杉、北美黄
Container seedling is to cultivate strong seedlings, improve the quality of afforestation, high-yielding forest yield an important technology. It is reported that in the late seventies, the number of container seedlings in Sweden accounted for 59% of the total seedling output, Finland accounted for 29%, Canada accounted for 34.6%, the United States accounted for 17%, Brazil, Thailand, Nigeria and other countries up to 70-90% , There is a trend to replace bare root nursery. In developed countries, container seedling has been specialized, industrialized and commercialized. The largest forestry conglomerate in the United States, Hershey Company, has a greenhouse with a total area of 11,000 square meters of thermostatic and sprinkler systems in Seattle’s nursery base for factory container nursery.
