The peach peel is yellowish, the meat is soft, the juice is juicy, and it is resistant to storage. It is a fruit that is loved by people. Many fruit farmers who planted peaches made a fortune. The following small series introduces the key points about the fertilization of peaches. 1. In the summer, the main method is to apply strong fruit fertilizer, and use a method of spreading a plot of land, and then ploughing a plot of land, the depth is about 10 cm. It is also possible to apply the base fertilizer from August to October in the autumn, and use the ditch, the hole or the application to plow the whole garden. If you encounter autumn drought, it is best to choose immediately after the rain. 2, base fertilizer. The base fertilizer advocates winter fertilizer and autumn application, mainly based on Sada's organic fertilizer, accounting for 60%-70% of the annual fertilization amount, 2000kg per mu, or 150kg per mu of Shizuo's fruit tree. 3, topdressing. The number, time and dosage of top dressing vary according to variety, age, cultivation management mode, growth and development period and external conditions, and are generally dominated by pre-emergence fertilizer, strong fruit fertilizer and post-harvest fertilizer. In addition, top dressing is an essential supplement to soil fertilization. 4. Fertilize before flowering. It is applied 15 to 20 days before flowering, mainly based on nitrogen fertilizer. Each plant can apply 0.5~1kg urea and boron fertilizer 0.25kg. Be sure to mix with farmyard manure. 5, flowering fertilizer. At the initial flowering stage, 0.2% boric acid aqueous solution was sprayed. According to different varieties, 0.4% potassium dihydrogen phosphate was sprayed 1-2 times in the late May to early September, and 0.2%-0.3% calcium nitrate was sprayed in the middle and long term of the fruit. 6, picking fruit fertilizer. 1.5 to 20 days before fruit picking, the fruit expansion speed is accelerated, and the application of potassium fertilizer can effectively improve the yield and quality of peach. After fruit picking, nitrogen and phosphate fertilizers are mainly used, and about 1.5 to 2 kg of urea and 1 to 1.5 kg of superphosphate are applied per 50 kg of fruit to promote root development and enhance wintering ability. The above is the summary of the peach fertilization collected by Xiaobian, for reference only.
