摘  要:
对野生杜鹃采取不同修剪强度的对比试验,结果表明:重回缩使野生杜鹃枝条平均生长量能达到40 cm,有利于枝条更新复壮;摘花使野生杜鹃抽出枝条达603条/m2,摘花有利于枝条抽出;短截枝条生长量5 843 cm/m2,短截能有效促进枝条生长量增加;短截使杜鹃花芽72.8个/m2,中回缩和重回缩花芽为0;短截杜鹃开花68.5朵/m2,开花数量最多。

摘  要:
The impact of different pruning way on Rhododendron simsii Planch was studied in this paper.The experimental results showed that heavy cutting-back contributed to branches accretion and rejuvenation,the average mass of growth reached 40 cm;plucking flower could help branches sprout,which caused the number of new branches to reach about 603/m2;heading-back cut increased so effectively the accretion of branches that the mass of total growth reached 5 843 cm/m2,and also caused the number of flower buds to reach 72.8/m2;media cutting-back and heavy cutting-back caused none flower bud;heading-back cut caused flowering number to reach 68.5/m2.This paper supplied some scientific basis on the future management of Rhododendron simsii Planch.
