番木瓜扦插快繁技术研究

Fast Propagation of Papaya by Cuttage

研究了4种基质、喷施生物型有机营养液“宇花灵”与番木瓜插条苗生根率及成苗率的关系,以及插条苗的龄期对移栽成活率的影响。结果表明:园土+木糠基质(2∶1)有利于番木瓜插条的生根成苗;叶面喷施“宇花灵”,番木瓜插条的生根成苗率高,且发病指数低;新芽长0.5～1.0cm时移栽,成活率最高,达到95%。

Effects of 4 matrixes, spraying of ＂Yuhualing＂, a kind of biotype organic nutrition on the rooting and seedling rate of papaya cuttings were studied. The results showed that garden soil ＋ bran medium was beneficial to rooting and seedling. Papaya plants sprayed with ＂yuhualing＂ had higher rate of rooting and seedling and lower disease index. The highest survival rate of transplants reached 95% when transplanted with the sprouts growing to 0.5- 1.0 cm long.
