谈培育高活力苗木的关键环节

苗木是造林的物质基础,苗木质量的高低直接影响更新造林的效果。一般认为,人工林保存率低的原因是苗木质量、造林的环境条件和造林技术等因素。造林用苗的质量对造林的保存率及将来人工林的生长起根本性的影响。由于目前对苗木质量从理论和实际两方面认识都不高,生产中常用低活力的苗木造林。鉴于上述情况,从生理生态学角度着重论述林业苗圃如何培育高活力壮苗的关键环节,以对育苗工作具有借鉴作用。

Study on the Key Point of Cultivating High Vigorous Seedling

The material foundation of afforestation is seedling, meanwhile the quality of tree seedling could directly impact on the reforestation effect. It's generally thought that there are several reasons leading to the lower preserving rate of forest plantations, such as the quality of tree seedlings, the environment of afforestation, and planting technique so on. Among them the quality of tree seedlings shows especially effect on the preserving rate and growth of forest plantations. Recently as the leak of the knowledge about the quality of seedlings in both theoretical and practical aspects, we usually use low vigor seedlings in practical production. In view of preset situation, this paper emphasizes the key point of cultivating high vigorous seedlings from the perspective of physiology and ecology which provides some references for cultivation.
