摘要
为提高油茶扦插育苗成活率和扦插苗的质量,采用正交试验设计方法研究激素、激素质量浓度、激素处理时间、基质配比、插条有无顶芽和插条品种6个因素对油茶扦插育苗效果的影响。结果表明:影响油茶扦插成活率、根系数量和根系长度的主要因素是激素质量浓度;影响油茶扦插生根率的主要因素是基质配比;基质配比为珍珠岩和蛭石体积比1︰1有利于油茶扦插成活率和生根率的提高,珍珠岩和营养土体积比2︰1有利于扦插根系数量的增加和根系长度的增长。综合分析得出,油茶扦插育苗最佳处理条件:激素种类为KIBA或NAA;激素质量浓度为300 mg/L;激素处理时间为60 s;基质配比为珍珠岩和蛭石体积比1︰1;插条去顶芽;品种为XL4号。
In order to improve survival rate of cutting and quality of cutting seedlings in Camellia oleifera, six factors were studied with orthogonal experimental design method, for example, hormones, mass concentration of hormones, hormone treatment time, medium composition, terminal buds and cuttings varieties. The results showed that the main factors was the mass concentration of hormones which affected survival rate of cutting, root number and root length in C. oleifera, and the main factors was medium composition which affected cutting rooting rate. The medium of perlite and vermiculite at the volume ratio of 1 ： 1 could improve survival rate and rooting rate, and the medium of peflite and nutrient soil at the ratio of 2 ： 1 could increase root number and length. The results of comprehensive analysis showed that the best cutting seedling treatments in C. oleifera method was cutting without terminal bud in XL4 was treated by 300 mg/L KIBA or NAA for 60 s and then inserted the medium ofperlite and vermiculite at the ratio of 1 ： 1.
