鸡血藤扦插繁育技术研究
|
摘要
本文以广东梅州野生及人工种植的多年生鸡血藤Spatholobus suberectus为材料,以提高鸡血藤扦插育苗繁殖系数为目的,对影响鸡血藤扦插生根的主要因素开展扦插试验。结果表明:人工植株和野生植株的穗条扦插生根率无显著差异;扦插基质类型对生根率有显著影响,采用黄心土作为基质生根效果最好; 1～3 a生枝条中,鸡血藤的木质化枝条生根率要高于半木质化嫩枝,粗度> 0. 8 cm的木质化枝条生根率最高;外源激素种类及其质量体积浓度均对扦插生根率产生显著影响,采用质量体积浓度为500 mg·L~(-1)的GGR浸泡插穗基部1h扦插生根效果最好;不同季节扦插对比试验显示春季扦插的生根率要显著高于其他季节;扦插方式试验表明营养袋扦插生根率与插床扦插无显著差异。
In order to study the main affecting factors on the rooting of Spatholobus suberectus cuttings and improve the propagation coefficient of cuttings,using the wild and artificial perennial S. suberectus in Meizhou City,Guangdong Province as materials to carry out cutting experiments. The results showed that: there was no significant difference in rooting rate of cuttings between artificial and wild plants. The type of cuttings matrix had significant effect on rooting rate,and loess was the best medium for rooting. The rooting rate of lignified branches of S. suberectus was higher than that of semi-lignified tender branches in 1 ～ 3 years,and the rooting rate of lignified branches with diameter > 0. 8 cm was the highest. The types of hormones and their concentrations had significant effects on the rooting rate of cuttings and the best rooting effect was to soak the base of cuttings in GGR with mass volume concentration of 500 mg·L~(-1) for 1 h. The rooting rate of spring cuttings was significantly higher than that of other seasons,and the cutting mode test showed that there was no significant difference between nutrient bag cuttings and bed cuttings.
