摘　　要：采用1/2、1/3、1/4和抹顶芽4种短截强度对节节红板栗结果母枝进行短截,研究其对雄花序数、雌花数、枝长、枝粗和结蓬数的作用效应。结果表明,1/2短截强度极显著地促进了枝长生长,显著促进了雌花数和结蓬数,枝粗比对照提高了27.39%,雄花序数比对照降低了19.67%;1/3短截对枝长生长和枝粗生长具极显著效应,雄花序数、雌花数和结蓬数分别比对照提高了13.93%、277.23%和301.34%;1/4短截和抹顶芽与对照相比无明显差异。The fruit branch of Castanea jiejiehong was short-cutted by four intensities, which were 1/2, 1/3, 1/4 and terminal bud, and the effect of which on the quality of male and female flower, length and thickness of branch and the quality of fleabane was studied. The results showed that after short-cutted of 1/2 intensity, the growth of branch was promoted very notablely, the female and fleabane increased notablely, the thickness of branch increased 27.39% compared with the contrast, and the quality of male flower decreased 19.67% compared with original one. After short-cutted of 1/3 intensity, the length and thickness of branch increased very notablely, and the quantity of male, female flowers and fleabane increased 13.93%, 277.23% and 301.34% respectively compared with original one. The effects of shortcutting of 1/4 intensity and terminal bud were not distinct.
