摘要
以扦插基质、生根剂种类、生根剂浓度和浸泡时间为影响因素,采用正交试验,研究其对红双喜月季扦插生根的影响,以期优化红双喜月季扦插繁殖技术。结果表明,生根率的最优处理组合为砂壤土∶珍珠岩∶蛭石=3∶1∶1+250 mg/L IBA+浸泡50 min;红双喜月季扦插平均生根数的最优处理组合为砂壤土∶珍珠岩∶蛭石=3∶1∶1+150 mg/LIBA+浸泡30 min;红双喜月季扦插平均根长的最优组合为砂壤土∶珍珠岩∶蛭石=3∶1∶1+300 mg/L NAA+浸泡10 min;综合指标红双喜月季扦插生根指数最优组合为砂壤土∶珍珠岩∶蛭石=3∶1∶1+200 mg/L[NAA+IBA(1∶1)]+浸泡10 min。
In this experiment,using cutting medium,rooting agent type and concentration and immersion time as factors,orthogonal test was adopted to study their effects on rose cuttings rooting in order to optimize the cutting propagation technique of red double delight Rosa chinensis.The test results showed that the optimal treatment combination for rooting rate was sandy loam:perlite:vermiculite=3∶1∶1+250 mg/L IBA+soaking for 50 min;the optimal treatment combination for the average rooting number of red double delight Rosa chinensis cuttings was sand loam∶perlite∶vermiculite=3∶1∶1+150 mg/L IBA+soaking for 30 min;the optimal combination of average root length of rose cuttings was sand loam∶perlite∶vermiculite=3∶1∶1+300 mg/L NAA+soaking for 10 min;the optimal combination of rooting index of rose was sandy loam∶perlite∶vermiculite=3∶1∶1+200 mg/L[NAA+IBA(1∶1)]+soaking for 10 min.
