幼龄桃树的明显特点是生长旺盛,其二、三年生表现最为突出。如果修剪不当,往往会推迟结果或产量不高。这一时期整形修剪的要求是既要造就良好的树体结构,又能获得早期产量。近年来,我们在生产中运用“一年促、二年控、三年调整”的修剪技术,使幼树定植后三年基本完成整形,在正常管理条件下,做到二年结果、三年丰产。现将具体技术要点分述如下。
The obvious characteristics of young peach trees are strong growth, the second and third years of the performance of the most prominent. If you prune improperly, you often postpone the result or the yield is not high. The requirement for plastic trimming during this period is to achieve both good tree structure and early yield. In recent years, we have used the pruning technique of “one year’s promotion, two years ’control and three years’ adjustment” in production to basically complete plastic surgery three years after planting. Under normal management conditions, we will achieve the result of two years and three years High yield. The specific technical points are as follows.
