摘 要: 以20株7 a生红锥(Castanopsis hystrix)优良单株为材料,研究不同截干高度对红锥萌芽效果的影响。结果表明:120 cm截干处理下,促萌效果优于其他处理,初始萌芽期最早,萌枝数、萌枝丛数、萌枝平均距地高都最高;红锥截干后的萌枝情况对光照的响应不显著;红锥截干可刺激主干上的隐芽萌发。 By selecting 20 seven-year-old superior Castanopsis hystrix individuals as the materials, this research studied the germination effectiveness of C. hystrix on different stem-cut heights. The results showed that the treatment on height 120 cm had the best effects compared with the other treatments, which had the earliest initial germination time, and the highest sprouting branch number, branches of cluster number and average height of branch to the ground. The sprouting branch after stem-cut showed no significant effects on light conditions. The stem-cut height had significant positive correlation between the sprouting branch number and branches of cluster number (P 〈 0. 05 ). Moreover, the stem-cut stimulated the germination of the kryptoblasts on the trunk.
