2001年3月至2003年10月,在元江县林木种苗管理工作站进行了6种森林蔬菜的育苗及修剪试验,结果表明,采用生长调节剂处理插穗后,可提高臭菜、树头菜、越南甜菜和刺五加扦插生根率,在大棚中最佳扦插时间生根率分别达80％、60％、80％、60％,吲哚丁酸好于ABTI*生根粉,大棚中扦插优于露天；其中刺五加最佳扦插时间为10月,其他3种为3月.南山藤和长蕊甜菜的种子育苗,出苗率分别为100％和92％；南山藤和长蕊甜菜最佳育苗时间分别为3月和8月.臭菜、南山藤、刺五加、树头菜和越南甜菜的最佳修剪高度分别为50 cm、50 cm、40 cm、60 cm和50 cm,与未修剪相比,分别提高了191.43％、415.63％、214.29％、336.94％和531.39％,修剪能大幅度提高森林蔬菜产量.%The experiments of cutting and pruning of six forest vegetables namely Dregea volubilis,Acanthopanax trifoliatus,Acacia irttsia,Crateva unUocularis,Melientha longistaminea and Sauropus androgynus were conducted in forest tree seed and seedling work station of Yuanjiang county from March 2001 to October 2003.The results showed that treating cuttings with growth regular,the rooting percentage of Acacia intsia,Crateva unilocularis,Sauropus androgynus and Acanthopanax trifoliatus,the best rooting percentage reached 80 %,60 %,80 % and 60 % respectively,the effect of 1BA and ABT1,the conditions of greenhouse was good for cutting,the optimum cutting time for Sauropus androgynus was October,and that for other species was March.The seed germination rates of Dregea volubilis and Melientha longistaminea were 100 % and 92 % respectively,and the optimum seedling raising time were March and August respectively.The optimum pruning height of Acacia intsia,Dregea volubilis,Acanthopanax trifolialus,Crateva unilocularis and Sauropus androgynus were 50 cm,50 cm,40 cm,60 cm and 50 cm respectively,which were 191.43 %,415.63 %,214.29 %,336.94 % and 531.39 % than the control without pruning treatment,implied thai pruning could significantly increase the yield of these forest vegetables.
