报道了出圃时不同围径、不同主根长度的橡胶树高截干苗大田定植成活和当年恢复生长情况。苗木围径大小、主根长度与其定植成活率和植后恢复生长速率有密切关系。出圃时围径９～１５ｃｍ的橡胶树高截干苗大田定植成活率高，恢复生长较快。围径９ｃｍ以上的苗木，主根长度以大于４５ｃｍ为宜；围径大于１１ｃｍ的苗木，主根长应大于５０ｃｍ。
Reported a different diameter when the nursery, the different length of the main root length of the rubber tree truncated stems field survival and then resumed growth. Seedling diameter size, the length of the main root and its colonization survival rate and rate of recovery after planting are closely related. At the nursery diameter 9 ~ 15cm rubber tree high cut stem seedlings field planting high survival rate, rapid recovery and growth. Surrounding diameter of more than 9cm seedlings, the main root length greater than 45cm is appropriate; circumference greater than 11cm of seedlings, the main root length should be greater than 50cm.
