有些梨树尤其是一些幼旺树,常常到了结果期而不见挂果,即使挂果也产量很低,迟迟不能丰产。这是由梨树的干性强,且顶端优势较为明显、幼树萌芽率高、成枝率低以及梨树的品种等原因造成的。加之不重视梨树的修剪,常使不少梨树数年空产,不见效益。 Some pear trees, especially some vigorous trees, often reach the end of their fruitless fructification period, even with low fruit yield and delays in high yield. This is caused by the dry and strong pear, and more obvious advantages at the top, the young seedling rate is high, the low rate of branches and pear varieties caused. In addition, do not pay attention to the pruning of pear, often many pear tree several years of vacancy, no benefit.
