Research into Growable Seedings Technique for Cuttage of Larix Kaemferi carr

不同激素、穗材大小对生根和生根插穗移植成活、生长有不同的影响。半木质化插穗长度应由10cm增加到15cm～20cm,直径应大于2mm。木质化插穗直径应大于2.5mm、长12cm～13cm。3或3条根以下的生根插穗移植成活率低。

There are different effect of different hormone and spike size on taking root, transplanted survival of rooted spike and its growing up.As a result,the length of cuttings which being semi-xglon should be enlarged from 10cm to more than 15-20cm,and their diameter should be over 2mm.Cuttings which being xylon should have their length and diameter more than 12-13cm and 2.Smm respectively.There are low surrival rates of transplanted spikes which have three or less than three fibrids of root.
