摘要
通过对彩色沙林周围土壤和森林植被的调查、评价 ,采用炮穴整地和“五个一”的造林技术 ,对 2 33hm2 的砂石山地进行改造 ,造林成活率达 98% ,次年保存率达 96 % ,1年生平均树高达 1 3m 。
On the basis of investigation and analysis on the soil and forest vegetation in the area of colored sand forest,the technique of site preparation by using explosion hole was studied.The results showed that the survival percentage and preservation percentage of afforestation reached 98%,96% respectively,the mean height of 1-year plantation was 1.3m,and the increment improved obviously contrasted with comparative experiment.
