龙眼、荔枝采用嫁接育苗,其嫁接成活率低。高压育苗虽然成苗率高,但繁殖系数低。针对这两种育苗方法存在的问题,我们进行了龙眼、荔枝、枇杷单、双芽高压育苗的研究并已获得成功。其特点是:①繁殖系数高(每1～2个芽就可以繁殖1株苗)。一株2年生的龙眼树一次可高压30～50株左右的龙眼苗。②长根成苗率高一般达90％以上。③方法简单, Longan, litchi grafted nursery, the graft survival rate is low. Although high-pressure seedling seedling rate, but low reproductive coefficient. In response to the problems of these two breeding methods, we conducted the research on longan, litchi, loquat single and double-shoot high-pressure breeding and have been successful. Its characteristics are: ① high reproductive coefficient (every 1 to 2 buds can breed 1 seedlings). A 2-year-old longan tree can be about 30 to 50 strains of longan seedlings. ② rooting rate is generally higher than 90%. ③ method is simple,
