以白兰(Michelia alba)为试材,于2013年12月对其10~20、20~30、30~40mm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;20~30mm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。
Taking Michelia alba as test material, the branches of three diameters of 10 ~ 20,20 ~ 30,30 ~ 40mm were sparsely branch tested in December 2013, Month follow-up measurement of the degree of healing of the cut, study the effect of quarter diameter and quarterly change on its healing, in order to provide theoretical basis for the pruning work of garden trees. The results showed that the rate of healing was consistent with the annual growth phenology of garden trees. The healing effect of 20-30 mm diameter was superior to that of the other two diameters, which was the ideal diameter of sparse branch.
