北亚热带露地甜樱桃修剪方法研究

Study on Pruning Method for Outdoor Sweet Cherry in Northern Subtropic Zone

调查了解汉中北亚热带甜樱桃枝芽特性,研究修剪反应,以枝芽特性和修剪反应为基础,开展了修剪方法试验研究。试验比较综合修剪管理、综合修剪管理PBO(果树促控制)、常规修剪PBO、常规修剪对甜樱桃枝条数量及枝条组成的影响、对产量及品质的影响。结果表明,3个处理对产量和品质都有一定提高,以处理1提高最大,处理2次之,处理2时效性最高。

In this paper,the characteristics of shoot buds and pruning response of sweet cherry were investigated in the northern subtropic zone of Hanzhong.Based on the characteristics of shoot buds and pruning response,an experimental study on pruning methods was carried out.The effects of comprehensive pruning management,comprehensive pruning management+PBO,routine pruning+PBO,routine pruning on the number and composition of branches,yield and quality of sweet cherry branches were compared.The results showed that the yield and quality under the three treatments were improved to a certain extent,the yield and quality were highest in treatment 1,followed by treatment 2,and the effectiveness was highest in treatment 2.
