摘要
为了提高易结香沉香品种嫁接育苗技术水平,于2021—2023年在福建省平和天马国有林场西蝉苗圃开展易结香沉香优良品种嫁接育苗试验。结果表明:在闽南地区沉香嫁接育苗的最佳时间为10月20日左右,选用约450 d苗龄的土沉香为砧木,砧木地径1.0~1.99 cm;接穗基径0.50~0.89 cm、经过剪顶促芽且每条穗条带有剪掉3/4面积的叶片2~3片;嫁接时用塑料带绑紧砧木与接穗后再用透明厚塑料袋套袋保湿;嫁接后约100 d开始全光炼苗,180 d平均成活率可达95%、萌芽枝数达2.7支·株^(-1)和萌芽长度23 cm以上;次年5月下旬平均苗高可达40 cm以上,可出圃造林。
In order to improve the grafting seedling technology of Aquilaria sinensis varieties that are easy to form fragrance,and meet the urgent need for high-quality clonal seedlings in production,a systematic research on grafting and seedling raising technology of fragrant varieties had been carried out.The results indicated that the grafting and seedling raising of A.sinensis would be carried out in the southern Fujian region around October 20th.About 15 months old soil A.sinensis should be used as the rootstock,with a ground diameter of 1.0~1.99 cm and a basal diameter of 0.50~0.89 cm for scions.The grafting should be carried out using materials that had undergone top pruning to promote sprouting and had 2~3 leaves cut off from (3)/4 of the area on each ear.During the grafting,the rootstock and scion would be tightly tied with plastic straps,and then a transparent and thick plastic bag would be used for moisturizing.After about 100 days of grafting,the seedlings would start to be fully polished,the strains with a high survival rate had an average survival rate of 95%,a sprout number of 2.7 branches per plant,and a sprout length of over 23 cm at 180 days after grafting.In late May of the following year,the average seedling height could reach over 40 cm and be used for afforestation.
