Effect of pruning intensity on growing and flowering of Rhododendron simsii Planch
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.
