以2年生‘夏普蓝’、‘园蓝’和‘杰兔’为试材,研究了回缩、重截、中截和轻截4种修剪方法对其幼树期植株新梢生长和枝量形成的影响。结果表明:对2年生的‘夏普蓝’、‘园蓝’和‘杰兔’幼树进行轻截、中截、重截和回缩4种修剪处理后,虽然轻截处理的萌芽率显著低于对照的萌芽率,但这4种方法修剪的植株枝量和成枝力均显著高于对照处理,且采用回缩修剪处理植株的枝量和成枝力均显著高于重截、中截和轻截3种修剪方法,表明在蓝莓幼树期充分利用其芽潜伏能力强与寿命长的特点,对植株进行回缩处理,并适时的对新梢进行摘心处理有利于树冠的形成,实现早结丰产。
Taking 2-year-old ’Sharp Blue’, ’Garden Blue’ and ’Jie-Rabbit’ as test materials, the effects of retraction, heavy cut, middle cut and light cut on their shoot growth and shoot formation Impact. The results showed that the seedling rate of light-cut treatment was significantly lower than that of light-cutted cuttings after light-cut, medium cut, heavy cut and retraction for 2-year-old young trees of ’Sharp Blue’, ’Yuanlan’ and ’Jiejie’ However, the shoots and shoots of the four treatments were significantly higher than those of the control treatments, and the branches and branches were significantly higher than those of the treatments of cut-off and cut-off And light cut three kinds of pruning methods, indicating that the blueberry saplings take full advantage of its latent capacity and long life expectancy, retracting the plant, and in time for the shoot topping treatment is conducive to the formation of crown, to achieve Early high yield.
