本文以珍珠岩、蛭石和壤土为基质,以双吉尔(GGR)、吲哚丁酸(IAA)和萘乙酸(NAA)为生根剂,采用随机区组试验设计,开展不同扦插季节、不同枝龄的香果树扦插育苗试验。研究表明,香果树扦插枝龄以6月龄嫩枝最佳,扦插季节以夏季为宜,扦插基质以蛭石最优,生根剂以双吉尔(GGR)200 ppm效果最好。采用“夏季嫩枝+蛭石基质+GGR200 ppm”的配套技术后,香果树扦插生根率可达68.61%。
In this paper, perlite, vermiculite and loam soil were used as substrate, GGR, IAA and NAA were used as the rooting agent. Randomized block design was used to study the effects of cutting season, The fragrant tree cuttage nursery experiment. The results showed that the best age of softwood cuttings was 6-month-old shoots, the softwood cutting season was the best in summer, the best cutting medium was vermiculite, and the best rooting agent was GGR 200 ppm. With the supporting technology of “summer shoots + vermiculite matrix + GGR200 ppm ”, the rooting rate of fragrant fruit trees can reach 68.61%.
