摘要
研究了不同年龄喜树母树上的嫩枝,在不同季节培育时的生根进程和插穗直径粗细不同对扦插苗生根和生长的影响。在泰山南麓人工间歇弥雾培育气候条件下,27天生根率可达77.62%以上。试验证明,内、外因子对喜树扦插生根的影响是不同的,其中内因是主导因子,生长素以NAA 2 000 mg/kg处理效果最好,基质以在素沙+炉灰(体积比1∶1)最好。在上述两种条件下,生根率最高可达86.4%。
Abstract This text makes in vestigations to the Camptotheca acuaminata different age of tress, studying the influences of different seasons and thickness different to take roots. In the conditions of southern Tai Mountains artificial climates, about twenty- senven days the rooting rate can reach 77.62 %. The test proves that inside and outside cultivation of rooting rate have different influences. Between them the inside cultivation influence is the first, the best dealing results in NAA2000mg/kg, the best cultivating environments is sand and ashes (volume 1:1), under the two kinds of conditions, the rooting rates can reach as high as 86.4 %.
