为给油茶良种优质苗木的培育与合理施肥提供理论依据,定量研究了赣无系列油茶24个无性系的生长规律,将其苗木生长过程划分为前慢期、速生期和后慢期3个阶段,从9月中旬开始各无性系的苗高与叶片都进入速生期,9月下旬达生长高峰,各无性系间生长量差异不显著,但不同生长阶段差异显著;同时,调查分析了各无性系苗木成活率与保存率变化情况,其中赣无24、赣447、兴46与赣190成活率较高,无24与赣84-3成活率较低;各无性系保存率随时间递减,其中赣84-8、赣83-1、赣447与赣无24最终保存率较高,而无12保存率最低,不到60%。
In order to provide a theoretical basis for cultivating high quality seedlings of Camellia oleifera and reasonable fertilization, the growth of 24 clones of Camellia oleifera was quantitatively studied. The seedling growth process was divided into three stages: pre-slow, fast-growing and post-slow From the middle of September, the seedling height and leaves of clones entered the fast-growing period, reached the peak of growth in late September, the difference of growth among the clones was not significant, but the difference was significant at different growth stages. At the same time, The survival rate of the seedlings and the preservation rate changes, of which Gan 24, Gan 447, Hing 46 and Jiangxi 190 survival rate is higher, no 24 and Gan 84-3 survival rate is low; the survival rate of each clone decreases with time, of which Gan 84-8, Gan 83-1, Gan 447 and Gan 24 were higher than those with 24, while the lowest ones were 12%, less than 60%.
