摘要
采用3种嫁接方法不同时期进行红松嫁接育苗及不同整地方式造林试验,结果表明:与劈接和单芽贴接法相比,采用舌接法嫁接成活率最高,达到了94.41%,劈接法成活率87.78%,单芽贴接法为83.52%;不同嫁接时期比较,4月25日和5月10日嫁接成活率最高,分别达到96.67%和95.33%。采用嫁接苗上山造林,各整地方式对造林成活率的效果依次为平台整地造林成活率96.67%>鱼鳞坑95%>竹节壕85.83%>嵌缝76.67%,属平台整地造林成活率最高。
Afforestation experiments of seedling-raising and different land preparation of Pinus koraiensis were conducted by three kinds of grafting methods.Result shows that：compared to split grafting and pith-cambium layer pairing grafting,adopting tongue grafting can obtain the highest survival rate,being 94.41%;the survival rate of split grafting and pith-cambium layer pairing grafting is 87.78% 83.52%,respectively.The survival rate of grafting is 96.67% 95.33% on April 25 and May 10,respectively.The descending order of the survival rate of all land preparation is：platform afforestation（96.67%）fish scale pit（95%）bamboo trench（85.83%）caulking（76.67%）.Among of them the afforestation survival rate of platform preparation is the highest.
