摘要
通过选取不同立地条件进行红松嫁接苗造林试验,分析影响红松嫁接苗造林成活率的关键因素,结果表明:除了嫁接苗质量问题导致造林成活率低以外,造林地选择和造林质量也是制约造林成活率的主导因子;因地制宜,适地适树,才能保证红松嫁接苗有较高的造林成活率。
Based on practice and observation to afforestation with grafted Pinus koraiensis seedling,the survival rates on the different site conditions were studied and analyzed.The results show that the key factors of affecting the survival rate of afforestation include quality of grafting seedlings,selection of afforestation land and forestation quality.So according to circumstances and matching species with the site are effective measures to increase afforest-ation survival rate.
