不同时期、不同处理方法的连翘压条繁殖研究

Studies on Layering and Multiplication of Forsythia Suspense with Different Processing Methods in Different Periods

目的:确定连翘最佳的压条时间和方法,完成连翘野生抚育的关键技术。方法:采用对照、环剥、纵刻、高锰酸钾和激素处理。生长期内每隔30 d选择母株样本处理,并做50株重复。结果:环剥和纵刻处理的生根速率、数量和质量最优;压条时间以6月中下旬为宜。结论:压条繁殖的成活率与株龄、枝龄、生长部位、发育状况、土壤、温度、水分等多方面的因素有关。

Objective：To determine the optimal time and method of layering and complete the key technology of wild tending of Forsythia Suspense.Methods：The processing method of contrasting,girdling,longitudinal engraving,potassium permanganate and phytohormone treatment.Every 30 d during the growing period,mother plant samples were selected for processing,and 50 repeat plants were made.Results：The root growth rate,quantity and quality of those processed with girdling,longitudinal inscribing methods were the optimal.Late June was the appropriate time for layering.Conclusion：The survival rate of layering multiplication is related with many factors,such as strain age,branch age,growth location,development status,soil,temperature,moisture and so on.
