整形修剪措施对幼龄桂花树生长的影响研究初报

Preliminary Report on Effect of Trimming Method for Growth of Young Osmanthus Fragrans Lour.

摘要:

以生长较直立的3 a生丹桂苗为试材,研究了不同主干高、主干数及拉枝、环割和环剥等技术措施对丹桂苗生长的影响.结果表明：随着主干高度的升高,桂花幼树树高和平均生长量升高,冠幅和总生长量降低;与主干高度正好相反,随着主干数的增加,桂花幼树树高和平均生长量降低,而冠幅和总生长量升高.

Abstract:

Effect to growth of Osmanthus fragrans Lour. with technical measures related to different main stem height, main stem number and pull-branch, ring-cut and ring-peel by using 3 years old seedling growing straight of Osmanthus fragrans Lour. was studied. The result showed that its young tree's height and mean increment went high, and crown and total increment went down along with increases of the main stem height; on the contrary, the young tree's height and mean increment went down, and crown and total increment went high along with increases of the main stem number.
