苦丁茶冬青扦插繁育技术研究

摘要

以苦丁茶冬青当年生半木质化的枝条作为扦插材料,通过对比试验研究植物生长调节剂、 处理时间和营养土配方与组合等对苦丁茶冬青扦插生根和装袋移栽的影响.结果表明,使用300 mg/L、 pH 6.5的萘乙酸(NAA)溶液处理8.0 h以上对苦丁茶冬青插穗的生根效果最佳,移栽的营养土采用黄泥、 河沙、 椰糠和牛粪并添加复合肥后混匀堆放熟化,对苦丁茶冬青种苗的装袋存活效果较好.%Semi-lignified shoots of Ilex kudingcha C.J.Tseng were selected for cuttings,and treated with different plant growth regulators to analyze the effects of the regulators, treatment duration and soil nutrient formula on the rooting of the cuttings and the survival rate of the cuttings transferred into bags. The results showed that the cuttings treated with pH6.5 NAA solution at 300 mg/L for 8.0 h had optimal rooting effect. The nutrient soil for bag-raising of the cuttings was prepared by mixing yellow mud, river sand,coconut coir and cow dung with compound fertilizer and allowing the mixture well composted.This composted mixed nutrient soil had good effect on the survival of Ilex kudingcha C.J.Tseng in the bags.
