To improve the quality of peaches, these points must be done well

1. Fertilize reasonably. Control the amount of nitrogen fertilizer and increase the amount of phosphorus, potassium, and organic fertilizer. Nitrogen fertilizer is conducive to fruit enlargement. With the development of fruit, it is necessary to gradually reduce nitrogen fertilizer and increase phosphorus and potassium fertilizer, which is conducive to fruit color and sweetness. For autumn base fertilizer, farmhouse manure or organic bacterial fertilizer is used to increase the amount of calcium and magnesium, which can improve the flavor of the fruit. Spraying medium and trace element foliar fertilizers during the expansion period is beneficial to improve fruit quality.

2. Extend the light time. Long light time is good for fruit coloring and sweetening. When pruning, choose a tree shape with high light efficiency, reduce the number of branches, directly produce fruiting branches on the main stem, remove the large fruiting branch group, and keep only the moderate fruiting branches. Control the appropriate number of fruiting branches, remove upright branches, dense branches, thin branches, and thick branches, maintain a suitable leaf area, and perform winter and summer shears reasonably.

3. Reasonably control output. The early-maturing variety is controlled at 1500-2000 kg, the middle-maturing variety is 2000-2500 kg, and the late-maturing variety is 2500-3000 kg. The number of fruits retained is determined according to the fruit size of different varieties. There are too many fruits, the fruits do not grow big, and the coloring and sweetness are not good.

4. Control the amount of watering. Ensure water supply during the fruit expansion period, and control the amount of watering in the later period. To prevent fruit cracking or cracking of the core, water can be intermittently watered. 15-20 days before picking, stop watering to control vegetative growth and increase fruit sweetness. In case of rain, dig deep trenches for drainage in time and pick peaches 5-10 days later to ensure the quality of peaches.

5. Fruit bagging. Bagging in the young fruit period can prevent pests and diseases, and the fruit surface is smooth and clean. However, the sugar content of the fruit will be reduced after bagging, so high-quality fruit bags with good ventilation and light transmission should be selected. In the later stage, the fruit bags must be removed in time to allow enough time to fully color and sweeten the fruit and improve the quality of the fruit.
