Relationship between cutting ear condition and strike ability of camphor pine

描述了樟子松穗条类型和着生部位、采条时期、插条粗细和长度、母树年龄等与生根率的关系 .结果表明 ,萌芽枝插穗比一般插条的生根率提高 3 9.3 % ;节间的插穗生根率比节上、节下提高 1 7%～ 6 0 % ;北方最佳的扦插时间为 5月 1日之前 ;5年生樟子松插穗适宜的规格是粗细为 0 .4～ 0 .6cm ,长短为 3～ 5cm .

The results showed that sprout shoot improved 39.3% than general shoot in strike rate,internode improved 17～60 percent than other position.The best cuttage time is before 1,May in north area.The suitable standard of 5 years camphor pine is 0.4～0.6 cm thickness,3～5 cm length.
