早酥梨是一个早熟、优质梨树品种。早酥生长特点是萌芽力很高,成枝力很低,短截后,只发出2个长枝和少数中枝,其余均为短枝。因而前期树冠稀疏、松散,枝量很少。另外,早酥梨干性强,层性明显。单枝生长量非常大,土壤及管理条件较好的单枝长度可达20m以上。我们根据早酥生长结果习性,在幼树的修剪中,打破了传统冬剪为主,夏剪为辅的修剪模式,采用了夏剪为主、冬剪补充新的修剪方法,克服了常规修剪的弊病,可提早成形2~3年,提前进入初果期1~2年,早期产量明显增加。现将具体做法介绍如下:
Morning pears pear is a precocious, high-quality pear varieties. Early Crisp growth is characterized by high sprouting budding force is very low, short cut, issued only two long branches and a few branches, the rest are short branches. Thus pre-sparse canopies, loose, very few branches. In addition, as early as dried pear crisp, distinct layers. Single branch growth is very large, soil and management conditions better single branch length up to 20m or more. According to the results of the early crisp growing habit, we pruned the pruning mode of traditional winter pruning and summer pruning supplemented by young pruning. The pruning mode is mainly summer pruning and the winter pruning is supplemented with new pruning methods, which overcomes the problems of conventional pruning Of the shortcomings, can shape early 2 to 3 years, early into the early stage of 1 to 2 years, early yield increased significantly. The specific practices are as follows:
