The peach tree spring management mainly refers to the management of the peach tree before germination, budding, flowering, fruit setting and fruit development. The main technical points are as follows: 1. Fermented peach shoots grow rapidly and fruit development period is short, so fertilization should be timely and reasonable. Spring fertilization mainly refers to the fertilization before germination, and the fertilization time should not exceed the late February. Early application is better. Fertilizer types are chemical ammonium bicarbonate, phosphate fertilizer, potassium fertilizer and organic fertilizer. Peach trees producing 35-50 kg of fruit were planted with high-quality rot and 40 kg of human feces, 0.25 kg of urea, 0.15 kg of superphosphate, and 0.4 kg of potassium chloride. Fertilization methods: Under the canopy, close to the root distribution area, dig 2-3 fertilization pits, apply the organic fertilizer and nitrogen, phosphorus, and potassium fertilizers into a well-mixed mixture, and timely cover the soil after application. In case of drought and more rain before budding, it is necessary to inject light manure water to resist drought and prevent water from being discharged. 2. Preventing Physiological Fruit Dropping Physiological fruit drop is an important issue in the growth of peach trees, and it is particularly prominent in rainy conditions. Peach physiological fruit drop has 3 periods: the first stage occurred after the cultivar, which was mainly caused by poor pollination due to pistil and pollen development; the second stage was due to the poor supply of tree nutrients during young fruit period; The third phase is the occurrence of a hard nuclear phase, which is mainly caused by the competition for nutrients and water between shoots and fruits. Also pay attention to pest damage and soil water and other factors. The fundamental way to overcome the physiological fruiting of peach trees is to adjust the tree vigor and regulate the contradiction between growth and results. Measures: (1) Peach trees with vigorous tree vigor should be applied as little or no nitrogen fertilizer as possible in the spring, and basal fertilizer should be used more often in the second half of the year; farmyard manure should be used in the second half of the year; (2) Control the vigorous growth of branch shoots before the hard nucleus stage. Take toppings and pruning. (3) Do a good job of trench drainage in Taoyuan during the rainy season to prevent waterlogging; (4) Apply 0.4% urea and 0.3% potassium dihydrogen phosphate to spray the crown during the fruit development to supplement the nutrition of peach trees. The lack of. In addition, it is necessary to do a good job in the prevention and control of pests during fruit development.
