通过正交试验L_9(3~4)研究了激素类型、扦插基质、激素浓度3个因素对1年生富贵榕(Ficus elastica Roxb.‘Schryver-iana’)嫩枝扦插生根的影响。结果表明,不同处理对嫩枝扦插生根有显著影响,各因素对发根数的影响顺序为激素浓度>扦插基质>激素类型,对最长根长、生根率和根系效果指数的影响顺序是扦插基质>激素浓度>激素类型,对平均根长的影响大小依次为扦插基质>激素类型>激素浓度,激素浓度是富贵榕嫩枝扦插生根数的决定因素,扦插基质是其他生根性状调查指标的主导因子。本次扦插最佳组合为3珍珠岩:1泥炭土基质、0.1%根太阳生根剂处理2h,对于富贵榕嫩技扦插的规模化设施育苗有一定的指导作用。
The effects of hormone type, cutting medium and hormone concentration on the rooting of shoots of Ficus elastica Roxb. ’Schryver-iana’ were studied by orthogonal experiment L9 (3-4). The results showed that different treatments had significant effects on the rooting of shoots. The order of the effects of various factors on rooting numbers was hormone concentration> cutting matrix> hormone type. The order of influence on the longest root length, rooting rate and root effect index was cuttage Matrix> hormone concentration> hormone type, the effect on the average root length was in the order of cuttage matrix> hormone type> hormone concentration, hormone concentration was the decisive factor for the rooting number of the softwood cuttings, and the cutting matrix was the leading index of other rooting traits factor. The best combination of cutting for the 3 perlite: a peat soil substrate, 0.1% root sunroofing agent for 2h, for the rich fig tender tender large-scale breeding facilities have some guidance.
