昆明地区冬季吊金钱扦插繁殖技术

Preliminary Study on Cuttage Propagation of Cerepegia woodii with Winter Condition in Kunming

探讨了吊金钱在昆明地区冬季能否进行扦插繁殖以及最佳扦插基质,分析了昆明冬季低温条件下吊金钱在珍珠岩、蛭石、沙子、泥炭土、珍珠岩+蛭石、见光水、不见光水7种扦插基质中的生根速度、生根率、成活率、生根数量和生根长度。结果表明:吊金钱在昆明冬季可进行扦插繁殖;7种介质中珍珠岩+蛭石处理在生根数量、生根长度、成活率三方面表现最好,见光水插在生根速度、生根率二方面存在优势。

Speed, rate, length, amount about taking root and survival rate of Cerepegia woodii in seven substrates（perlite, vermiculite, sand, turves, perlite and vermiculite, water in sunlight and water in dark） were analysed with Kunming winter condition to probe into feasibility for cuttage propagation and best substrates for Cerepegia woodii. The result showed that Cerepegia woodii could be reproduced by cuttage propagation with Kunming winter condition. Perlite and vermiculite was most fitting for Cerepegia woodii at taking root length, amount and survival rate in seven sub- strates. And water in sunlight was most fitting for taking root speed and rate.
