不同悬空培养高度对橡胶树小筒苗接穗生长的影响

摘要

The effects of the rubber diminutive poly-tube budding growth by different culture suspended cylinder height were studied, provide the theoretical basis for the cultivation of fine small tube seedlings of rubber tree. The results show that: small tube seedling root piercing and at the bottom of the tube suspended is closely related to and different hanging height of small tube seedling growth also has a significant impact; wear high rooting ratio of small tube seedlings grow better, but colonization is time-consuming, the survival rate is low. The suitable isolation layer height of culturing rubber diminutive poly-tube budding were 4 cm or more than 4 cm, at this time, the survival rate of the field is relatively high.%研究了橡胶树小筒苗筒底的不同悬空培养高度对其接穗生长的影响，为橡胶树优良小筒苗的培育提供理论依据。结果表明：小筒苗的根系穿出情况与筒底悬空高度密切相关，不同悬空高度对小筒苗的长势也具有显著影响；穿根率高的小筒苗长势较好，但定植费工费时，成活率较低；培育小筒苗适宜的控根隔离层高度是4 cm或4 cm以上，此时其大田定植成活率相对较高。
