不同修剪方法对樱桃树体生长的影响

Effects of Different Pruning Methods on Development of Cherry

为了提高贵州樱桃树体的管理水平,采用不同修剪方法对4～5年生樱桃树生长发育的影响进行了研究。结果表明,通过合理修剪能够提高母枝的萌芽率和成枝率、新梢的发生量和生长量,以修剪1/5的效果最好;对母枝短截1/3处理后,母枝着生角度与主干的角度越大,新梢的发生量越大,长度越短,生长量越小;对母枝1/3短截处理后,母枝在上一级母枝上的着生位置越靠上部,母枝抽发新梢的发生量和生长量就越大。

Effects of different pruning methods on growth and development of 4-5 years old cherry were studied to improve the management of cherry in Guizhou. The results showed that reasonable pruning improved the budding rate and branch rate of mother branch, also increased the amount and length of new shoot, especially pruning 1/5 was the best treatment. In the treatment of pruning 1/3 for mother branch, more new shoot generated when the angle of mother branch and main branch was bigger, while length of new shoot was short when the length of mother branch was short. Amount and length of new shoot could increase when the position of mother branch was higher than previous mother branch after the pruning 1/3 treating of mother branch.
