一、死树原因1、树种特性。大樱桃是喜温而不耐寒的落叶果树,其木质结构较其它北方落叶果树疏松.枝条皮层蜡质少,在冬季,冻溶交替的环境中极易失水。2、生长势过强。大樱桃幼树期营养生长旺盛,枝条加粗生长和加长生长较其它北方落叶果树都快。一般情况下,大樱桃进入大量结果的年限约7年,是果树中进入结果期较晚

First, the dead tree reasons 1, species characteristics. Cherry is a warm and not hardy deciduous fruit trees, its wood structure than other northern deciduous fruit trees loose. Branches cortical wax less, in winter, freeze-thaw alternating environment easily lose water. 2, growth potential is too strong. Large saplings grow vigorously young saplings, branches bold growth and lengthen growth faster than other northern deciduous fruit trees. Under normal circumstances, large cherry into the results of a large number of years about 7 years, fruit trees into the late results
