一些苹果树常因品种、修剪、结果等因素,形成树体一年结果多,一年结果少的“大小年”现象。“大小年”果树对产量、果质、效益都有一定的影响。对于“大小年”结果的苹果树,除了改进施肥方法,合理留果外,冬季进行科学的整枝修剪,也是防止“大小年”结果的一项重要而有效的技术措施。因此,在冬季进行修剪时,要根据“大小年”生长结果的特点而分别采用不同的修剪方法,通过科学修剪实现年年盛果年年高产。
Some apple trees often due to variety, pruning, the results and other factors, the formation of trees more than one year results, a year less “size year” phenomenon. “Year of the Year” fruit trees on yield, fruit quality, benefit has a certain impact. For apple tree with “Year of the Year”, in addition to improving fertilization method and keeping fruits reasonably, scientific winter pruning is also an important and effective technical measure to prevent the “Year of the Year” result. Therefore, during the pruning in winter, different pruning methods should be adopted according to the characteristics of the growth results of “Year of the Year”, and the high yield of annual fruit should be achieved by scientific pruning.
