梨树是我县果树栽培的主要树种,年产梨7—8万吨,其中秋白梨占70%。梨树的大小年结果现象始终是生产上需要解决的问题,一般除采取人工授粉、疏花疏果等措施外,主要通过修剪进行调节。由于在大树上进行人工授粉和疏花疏果有很多不便,所以采用冬剪措施调节大小年结果非常必要。经过多年的实践探讨,摸索出克服盛果期梨树大小年结果的一种修剪方法——多年生结果枝缩剪法。即通过对多年生结果枝进行短截回缩,刺激隐芽萌发而使其抽枝并当年形
Pear tree is my county fruit tree cultivation of major tree species, with an annual output of 7-8 million tons of pear, which fall white pear accounted for 70%. Pear tree size year-end result phenomenon is always the production of the problem to be solved, in addition to take the general artificial pollination, thinning and other measures of thinning, mainly through the regulation of pruning. Due to the inconvenience of artificial pollination and flower thinning on large trees, it is necessary to adopt winter shear measures to adjust the annual and annual results. After many years of practice, we explored a pruning method to overcome the perennial pear tree size year-end results - the perennial result of branch pruning shear method. Through the perennial results branch short retraction to stimulate bud bud germination and make the current year
