摘要
[目的]研究中山杉在沿海地区的露地扦插繁殖技术。[方法]采用嫩枝扦插方法，通过单因子比较试验，研究适宜沿海地区露地扦插中山杉的扩繁条件。[结果]通过10 cm砂石层将扦插床隔离地面，采用全光照喷雾控制叶片湿度达90％，于6月中下旬在3年生中山杉母本上采集插穗，并采用500 mg／L的NAA和1000 mg／L的IBA分别处理30 s，扦插于体积比3∶3∶4的泥炭土、蛭石和园土混合基质中，可获得最大生根率为93．67％的扦插效果。[结论]该研究为在沿海地区建立中山杉的快繁体系提供依据。
Abstract
Objective] To study cutting propagation techniques of ‘Zhongshanshan’ in open field in coastal areas.[Method] Suitable condi-tions for propagation of ‘Zhongshanshan’ in open field in coastal areas were studied by cutting tender branches through single factor comparison test.[Result] When a cutting bed was separated from the ground by 10 cm gravel layer and leaf humidity was kept at 90% by full-illumination spray, cutting slips were collected from female parents of three-year-old ‘Zhongshanshan’ in late June and were treated by 500 mg/L NAA and 1 000 mg/L IBA for 30 s.After they were planted in the mixture of peat soil, vermiculite and garden soil (their volume ratio was 3∶3∶4), the highest rooting rate was up to 93.67%.[Conclusion] The research can provide a reference for the establishment of rapid propagation system of‘Zhongshanshan’ in coastal areas.
