通过对吕宋芒不同环剥宽度和不同环剥时期的试验，探讨了不同环剥宽度、不同环剥时期对花序分化率的影响。结果表明，环剥促进花芽分化最佳期为１０月２５日－１１月１５日，环剥适宜宽度为枝组直径的１／１０－１／５。
The effects of different girdling widths and different circumscription periods on the differentiation rate of inflorescence were discussed through the experiments of different girth widths and different girdling periods in Luzon Mountain. The results showed that the optimal cycle of flower bud differentiation by girdling was from October 25 to November 15, and the suitable width of girdling was 1 / 10-1 / 5 of the diameter of branch group.
