水曲柳是我国重要珍贵工业用材树种之一,材质优良,用途广泛,自然分布在东北小兴安岭一带,是国家三级保护植物。为了丰富本地阔叶树种资源,改变新昌县造林树种单一状况,于1985年开始,相继从东北引进水曲柳苗木5100株和种子195千克,进行造林和育苗试验,并于去年九月通过了省级鉴定。该项试验居省内领先水平,引种规模系全国首见。现将水曲柳育苗造林技术总结如下: 1.种子催芽:水曲柳种子休眠期长,如不经催芽处理,播后当年不会发芽。为了破坏种子休眠期,可用低温窖藏层积处理的方法处理种
Fraxinus mandshurica is one of the most important species of timber for industrial use in China. It is of good quality and wide range of uses. It is naturally distributed in the area of Xiaoxing’anling in the northeast and is a national protected plant of the third grade. In order to enrich the resources of local broad-leaved species and change the single status of afforestation tree species in Xinchang County, starting from 1985, 5100 strains of seedlings and 195 kg of seeds were introduced from northeast China. Afforestation and nursery experiments were carried out. In September last year, Identification. The test ranks the leading level in the province, the introduction of the size of the first national opinion. Now Manchurian afforestation afforestation technology is summarized as follows: 1 seed germination: Ash seed dormancy period, such as without germination treatment, sowing that year will not germinate. In order to destroy the seed dormancy period, the seedlings can be treated with low temperature cellar stratification treatment
