早酥梨幼树成枝力弱、发枝量小、干性强,对中央领导干采用传统的截干法修剪发枝很少,且易出现上强下弱的生长不平衡现象,造成幼树长势旺、成形缓,延迟成花和结果。针对这一问题,我们在本校200亩实习基地梨园中,对二和三年生早酥梨的中央领导干延长枝连续两年进行了曲干法修剪试验,获得了良好效果。 As early as young pear pear branch force weak, small amount of branches, dry strong, the central leadership of the traditional truncated stem truncated little branches, and prone to weak strong growth imbalance, resulting in young Growing trees, slowing down, delaying flowering and ending. In response to this problem, in our 200-acre base of pear orchards, we conducted a dry-to-dry pruning test for central leaders of two-and three-year-old morning pears for two consecutive years and achieved good results.
