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,这一时期的管理得当,不仅增加树体营养,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。其主要措施为: 一、叶面喷肥、合理施肥 桃采收后,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0.3％～0.5％磷酸二胺,以提高叶
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, proper management during this period not only increased tree nutrition, increased its resistance to the adverse environment and winter power, but also played an important role in the flowering, growth and fruit harvest of the following year. The main measures are as follows: First, the foliar fertilizer, fertilizing peach reasonable harvest, the foliar spray every 10 days 0.5% to 1% urea and 0.3% to 0.5% potassium dihydrogen phosphate or 0.3% to 0.5 % Phosphoric acid diamine to raise the leaf
