李子树低产的主要原因是早春花期遭到低温影响授粉结实,以及栽培管理粗放等。根据我们实践,对大多数李树园,只要稍加重视,科学管理,产量基本上可以提高一倍,并可以克服大小年现象。 一、冬季合理整枝修剪 李树顶端优势强,萌芽力、成枝力也都比较强。枝梢节间也较短,芽多,新 The main reason for the low yield of plum tree is the low temperature in early spring flowering pollination and strong, and extensive cultivation and management. According to our practice, for most Li Shuyuan, with a little emphasis on scientific management, the output can be basically doubled and the annual size can be overcome. First, the pruning of winter pruning pruning top edge of strong, germination, branch force are also relatively strong. Branch shoots are also shorter, buds, new
