我们大兴安岭气候比较寒冷,年平均气温在-2℃左右,无霜期短,全年只有一百天。因此,常规裸根育苗一般需二年以上方能出圃造林,且造林成活率又不高,为改变这一状况,我们松岭林业局81年以来,每年均采用塑料温室内容器育苗方法,育苗20万左右,三年来先后采用了大兴沟产的硬塑杯,自产的塑料薄膜杯及广西林科所的横格式蜂窝状纸杯等三种容器,经对比试验表明,以蜂窝状纸杯为最好,其中主要特点是通气、透水、保肥性能好,利于苗木生长、育苗效果明显好于其它二种容器。
We Daxinganling relatively cold climate, the average annual temperature of -2 ℃, frost-free period is short, only one hundred days throughout the year. Therefore, the conventional nursery root nursery generally take more than two years before they can afforestation afforestation, afforestation survival rate is not high, in order to change this situation, Songling Forestry Bureau since 81 years, each year using plastic greenhouse container nursery methods, nursery 200,000 or so. Over the past three years, Hudong plastic production cup, plastic film cup made by ourselves and horizontal format honeycomb paper cup made by Guangxi Linke Institute have been adopted. The comparison shows that the honeycomb paper cup is the most Well, the main features of which are aeration, water permeation and good fat-keeping performance, which are good for the growth of nursery stock and the nursery effect is obviously better than the other two kinds of containers.
