利用塑料大棚生产容器苗和造林,是育苗生产和造林事业的一项技术改革。我国大棚容器育苗从七十年代中期开始试验,目前正逐步向生产过渡。广东、广西容器苗生产历史长,发展速度快。湖南、湖北、北京市容器苗的比重也迅速增加。牡丹江林区是1977年开始研究这项新技术。牡丹江林管局科研所五年来先后建棚四座,面积2830平方米,先后培育了16种针,阔叶乔木树种的容器苗
The use of plastic shed production container seedlings and afforestation, nursery production and afforestation is a technical reform. China’s greenhouse seedlings from the mid-seventies experiment, is now gradually transition to production. Guangdong, Guangxi container seedlings have a long history of production, rapid development. The proportion of container seedlings in Hunan, Hubei and Beijing also increased rapidly. Mudanjiang forest in 1977 began to study this new technology. Over the past five years, the research institute of Mudanjiang Forestry Administration has built four canopies with an area of 2830 square meters and successively cultivated container seedlings of 16 kinds of needles and deciduous tree species
