- 摘要:
- 以白兰（Michelia alba）为试材，于2013年12月对其10～20、20～30、30～40 mm这3个直径的枝条进行疏枝试验，并于2014年3、6、9、12月跟踪测量截口的愈合程度，研究了截口直径、季度变化对其愈合的影响，以期为园林树木修剪工作提供理论依据。结果表明：截口愈合速度与园林树木年生长物候相一致；20～30 mm直径的截口愈合效果明显优于另2个直径的截口，是较理想的疏枝直径。
- Abstract:
- Three sizes of branches of Michelia alba were pruned (thinned) during December 2013，and their wounds(10-20 mm,20-30 mm,30-40 mm)were measured in March，June，September and December 2014，to find out how size and seasonal change influence wound closure，for providing scientific basis on tree pruning practice.The results showed that wound closure speed changed along with tree growth，and medium wounds (20-30 mm)which was the appropriate size to prune with further closure，closed faster than small wounds (10-20 mm) and large wounds (30-40 mm).
