进行了伊桐大田扦插繁殖育苗试验,对伊桐插条选择、应用GGR对伊桐插条处理等问题进行了分析。结果表明:2年生无处理插条平均成活率高于1年生无处理插条;浓度为0.01%、0.02%的GGR溶液处理过的2年生插条和1年生插条平均成活率、苗高分别比未处理的高20%。
The cuttage propagation experiment of Ipomoea aquatica was carried out. The selection of Yitong cuttings and the treatment of Yitong cuttings by GGR were analyzed. The results showed that the average survival rate of 2-year untreated cuttings was higher than that of 1-year untreated cuttings. The average survival rate and height of 2-year-old cuttings and 1-year-old cuttings treated with GGR at 0.01% and 0.02% 20% more than untreated.
