摘要：

为研究软枣猕猴桃嫩枝扦插生根效果的影响因子，以软枣猕猴桃当年生嫩枝为试验材料，研究生长调节剂(IBA)浓度和扦插基质对插穗生根率、根系宽、根系长和新梢长的影响，使用隶属函数法获得软枣猕猴桃嫩枝扦插最佳繁殖条件。结果表明，IBA浓度对软枣猕猴桃雌株插穗生根率和新梢长度影响显著，对雄株插穗根系宽和根系长度影响显著；同一IBA浓度下，软枣猕猴桃雌雄株两者间部分生根指标存在显著差异。扦插基质对软枣猕猴桃插穗生根率、根系宽、根系长和新梢长均有显著影响。隶属函数评分结果表明，雌株扦插以6000 mg/L IBA得分最高为0.706，雄株扦插以2500 mg/L IBA得分最高为0.780；扦插基质得分排序为椰糠:珍珠岩=1:2（体积比）(0.997)>泥炭:珍珠岩=1:2（体积比）(0.933)>椰糠(0.911)>泥炭(0.872)>熟稻壳:珍珠岩=1:2（体积比）(0.635)>熟稻壳(0.027)。综上，软枣猕猴桃雌株在IBA 6000 mg/L浓度处理下、雄株在IBA 2500 mg/L浓度处理下扦插生根效果最佳，扦插基质以椰糠:珍珠岩=1:2（体积比）、泥炭:珍珠岩=1:2（体积比）生根效果最佳。

Abstract:

In order to study the influencing factors of Actinidia arguta softwood cutting, annual branches of A. arguta were used as experimental materials to study the effects of growth regulator (IBA) concentration and cutting substrate on the rooting rate, root width, root length, and new shoot length of softwood cuttings. The membership function method was used to obtain the optimal reproductive conditions for softwood cuttings of A. arguta. The results showed that the concentration of IBA had a significant effect on rooting rate and new shoot length of female plants cuttings, while it had a significant effect on root width and root length of male plants cuttings. At the same IBA concentration, there were significant differences in some rooting indicators between female and male plants. The cutting substrate had a significant effect on the rooting rate, root width, root length, and new shoot length of A. arguta. The scoring results of the membership function indicated that the highest score for female cuttings was 0.706 at IBA 6000 mg/L, while the highest score for male cuttings was 0.780 at IBA 2500 mg/L. The order of cutting substrates scores was coconut coir: perlite=1:2 (volume ratio) (0.997)> peat: perlite=1:2 (volume ratio) (0.933)> coconut coir (0.911)> peat (0.872)> cooked rice husk: perlite=1:2 (volume ratio) (0.635)> cooked rice husk (0.027). In summary, the optimal concentration of IBA for softwood cuttings of A. arguta female plants is 6000 mg/L, and for male plants it is 2500 mg/L. The best cutting substrate for softwood cuttings of A. arguta is coconut coir: perlite=1:2 (volume ratio) and peat: perlite=1:2 (volume ratio).
