桃采收后,其叶片制造的养分不再供给果实,而是用于花芽的进一步分化、枝干加粗、组织成熟及营养物质的积累。因此,这一时期管理得当,不仅能增加树体营养,提高其对不良环境的抵抗力、越冬力,而且对翌年的开花、长势和果实丰收起着重要作用。一、叶面喷肥、合理施肥。桃子采收后,每隔10天对叶面喷1次0.5%～1%尿素及0.3%～0.5%磷酸二氢钾或磷酸二胺,以提高叶片光合功能。秋季要确定合理的施肥量,
After the peach harvest, the nutrients produced by the leaves are no longer supplied to the fruit, but are used for the further differentiation of the flower buds, thick branches, tissue maturation and nutrient accumulation. Therefore, properly managed during this period can not only increase tree nutrition, increase its resistance to the adverse environment, winter power, but also play an important role in flowering, growth and fruit harvest the following year. First, the foliar fertilizer, fertilization. Peach harvest, every 10 days on the foliage spraying 0.5% ~ 1% urea and 0.3% ~ 0.5% potassium dihydrogen phosphate or diamine phosphate to improve leaf photosynthetic function. Autumn to determine a reasonable amount of fertilizer,
