目的:研究皂荚刺用林良种“洛皂刺1号”的最佳无性繁殖技术。方法:嫁接采用嵌芽接、劈接、插皮接和芽接四种无性繁殖技术;砧木采用2年生皂荚实生苗,接穗采用“洛皂刺1号”品种带刺的一年生枝条;时间在3月份、6月份、8月份进行。结果:采用嵌芽接于8月份嫁接的成活率达到93%,8月份嫁接的成活株数当年平均株高达159 cm,第一年主干结刺株率达到96%,第二年主干结刺株率达到100%,嫁接部位伤口愈合良好。结论:采用四种嫁接方法,以嵌芽接最好,嫁接时间以8月份最佳,接穗必须采用带刺的一年生枝条上的芽,砧木采用2年生皂荚实生苗。
Objective: To study the best asexual propagation technology of Acacia crassicarpa ’Linolipong 1’. Methods: Four kinds of vegetative propagation techniques were introduced, such as inoculation, cleavage, insertion and splicing. Rootstocks were treated with 2-year old seedlings of saponins and the scion was spiked with annual branches of “Prodigalou No.1” , June, August. Results: The survival rate of grafting in August was 93%. In August, the average number of surviving grafts reached 159 cm in the same year, and the rate of primary sting was 96% in the first year. The rate of the primary sting was the second year 100%, the graft site wound healing well. Conclusion: Four kinds of grafting methods are the best in budding budding. The grafting time is the best in August. The scion must use buds on annual branches with barbed needles, and the rootstocks use 2-year-old germinating seedlings.
