软枣猕猴桃扦插繁殖技术体系研究

Study on Branch Cutting Breeding Technology System of Actinidia arguta

  • 摘要: 为进一步提高软枣猕猴桃苗木繁殖速度和繁殖系数,降低种苗生产投入的成本。以3种不同生长年份的枝条为基本材料,通过2种生根剂设置5种不同激素浓度组合浸泡枝条12 h,并结合3种不同基质及不同季节进行扦插对比研究。结果表明,软枣猕猴桃在夏季选择一年生枝条浸泡在400 mg/L IBA溶液并扦插在V河沙∶V草炭土∶V红壤土=4∶2∶1的基质中效果最好,培养60 d后逐渐生根,生根率为(88.90±3.81)%、成苗率为(90.66±1.15)%,植株长势健壮,须根多,根系粗。

     

    Abstract: To improve the reproduction rate and reproduction coefficient of Actinidia arguta seedlings and reduce the cost of seedling production, branches of three different growth years were used as the basic materials, and branches were soaked in five different concentrations of two kinds of rooting agents for 12 hours, combined with three kinds of different substrates and different seasons to make a comparative study of cutting. The results showed that the best results were obtained when the annual branches were immersed in 400mg/L IBA concentration and cut in the substrate of river sand, peat soil and red loam(4∶2∶1) in summer. After 60 days of culture, the root was gradually rooted, and the rooting rate was(88.90±3.81)% and the seedling rate was(90.66±1.15)%, which had many fibrous roots and thick roots with strong growth.
