选择胸径8~9cm的樟树、景烈白兰和杜英大苗进行移栽试验。采用完全随机区组试验设计,分别设不同树种、不同大小土球和不同枝叶留量等3种对比试验,比较苗木移栽成活率及成活后树冠的生长量。通过调查、统计和分析,结果表明:(1)根系发达的树种,大苗移栽效果好。(2)采用大土球移栽有利于大苗成活,根系越弱的树种,对带的土球要求越高。(3)适当留一些枝叶,有利于大苗生长。
Select the diameter of 8 ~ 9cm camphor tree, Jinglie Prynne seedlings and Du Ying transplanting test. A completely randomized block design was used. Three kinds of comparative experiments including different tree species, different sizes of soil balls and different branches and leaves were used to compare the survival rate of transplanted seedlings and the crown growth after survival. Through the investigation, statistics and analysis, the results showed that: (1) the root system developed tree seedlings transplanting effect. (2) The use of large soil ball transplanting is conducive to the survival of large seedlings, the weaker root system of trees, the higher the requirements of soil with the ball. (3) Appropriate to leave some branches and leaves, is conducive to the growth of large seedlings.
