用正劈接、短枝腹接、斜劈接和舌接在控水区与灌水区分别对龙眼地苗进行嫁接。结果表明,控水区嫁接苗的平 均成活率比灌水区的平均嫁接成活率高33．5％。从嫁接成活率来看,控水区正劈接极显著高于其它所有处理,其短枝腹 接、斜劈接表现也很好,而在灌水区的表现,4种嫁接方法也以正劈接最好,其余3种方法为所有处理之中最差的。接穗 抽发1年后,抽枝长度和粗度各处理间差异不显著。 With the positive split access, short splicing Aberdeen, oblique splice and tongue connected in the controlled area and irrigated irrigation area respectively, longan seedlings grafting. The results showed that the average survival rate of grafted seedlings in controlled area was 33.5% higher than the average grafting survival rate in irrigation area. From the grafting survival rate point of view, water control area is significantly higher than the other cleaved access to all the treatment, the short splinter, oblique splice performance is also very good, but in the irrigation area performance, the four grafting methods are positive split The best access, the remaining three methods for the worst of all the processing. One year after scion extraction, there was no significant difference in the length and thickness of the spiked branches.
