秋季果实采收后,果树除了叶片其他器管生理活动微弱,树体进入贮藏营养物质的时期,叶片的呼吸变弱,消耗少,积累多,叶片中的部分氮、钾等营养物质落叶前回流到枝条中,此期加强管理,对于增加树体营养、促进花芽分化、增强树势,安全越冬有重要作用。 After the fruit harvest in autumn, the fruit trees except for other organs of the leaves have weak physiological activities, and the tree enters the stage of storing nutrients, the leaves have weaker respiration, less consumption and more accumulation, and some nutrients such as nitrogen and potassium in leaves are deciduous To the branches, this period to strengthen management, for increasing tree nutrition, and promote flower bud differentiation, enhance the tree vigor, safe winter has an important role.
