无刺朝仓椒嫁接育苗试验研究

A Study of Grafting and Seedling Raising Experiments non-stinging Zanthoxylum japonica

为探索无刺朝仓椒嫁接技术,以嫁接时间、嫁接方法、砧木类型为因素,开展了日本无刺花椒止止吕美系无刺朝仓椒的嫁接育苗试验研究,结果表明:(1)朝仓椒春季嫁接的最佳时间为2月下旬至3月中旬,最佳嫁接方法是单芽切接法,平均成活率为85.7%,最高94.1%;(2)朝仓椒夏季最佳嫁接时间为6月底至7月上旬,最佳嫁接方法是方块芽接法,平均51.6%,最高77.6%。(3)竹叶花椒和朝仓椒具有很强的嫁接亲和性,其中以狗屎椒为砧木的朝仓椒嫁接苗平均成活率、平均高生长量、平均地径生长量最高。

In order to explore the grafting and seedling raising technology for non-stinging Zanthoxylum japonica,experimental researches were conduced on the grafting method and the seedling raising. The results showed that(1) The best time for grafting of Z.japonica in spring was from late February to mid-March. The best grafting method was single-bud cutting, with an average survival rate of 85.7% and a maximum of 94.1%.(2) The best time for grafting of Z.japonica in summer was from the end of June to the beginning of July. The best grafting method was the block grafting, with an average of 51.9% and the highest rate of 77.6%.(3) Four varieties of Z. armatum DC and Z.japonica had high grafting affinity. The average survival rate, average high growth and average ground diameter growth of grafted seedlings were the highest with Z.armatum as rootstocks.
