How to Store Fresh Peaches to Extend the Supply Period
Peaches have many varieties, and with early, mid and late maturing types and different growing methods, they are supplied to market successively from April to October.

If suitable fresh-keeping methods are adopted, the supply period of fresh peaches can be extended and economic returns improved. Harvest without injury, grade and pack. To judge peach fruit maturity: first, after the fruit has fully developed, the skin begins to lose its green color, the flesh is slightly firm, and colored varieties have basically reached full color, this is the firm-ripe stage. Second, when the fruit's ground color is light green and the fuzz on the fruit surface begins to color, it is at the seven-to-eight-tenths ripe stage. Firm-ripe stage

How to prevent and treat gummosis in peach trees? A detailed guide to practical methods
1. Distribution: Peach gummosis, also known as resin disease, occurs commonly in all peach-growing regions of our country, and is especially severe in the south. The causes are complex, and it is not easy to completely control. Gumming weakens tree vigor, affects fruit quality, and can even kill branches and trees. 2. Symptoms: This disease mostly occurs on the branches and trunk of peach trees, and is most likely to occur at the main trunk and the forks of main branches. In the early stage, the diseased part swells slightly and gradually exudes a translucent gum, which worsens after rain.

Orchard management after peach harvest cannot stop
After peach fruit is harvested, the assimilation of the leaves continues, and nutrients begin to accumulate in the tree body. Summer and autumn are also the period of flower bud differentiation. From fruit harvest to leaf fall, the amount of nutrients accumulated by the tree body and the quality of flower bud differentiation are closely related to the yield and quality of next year's peaches. Therefore, after the peaches are picked from the trees, management is not over and still must be strengthened. 1. Apply post-harvest fertilizer. After fruiting, the tree body has consumed a large amount of nutrients, so nutrients must be replenished in time to restore tree vigor, enhance the photosynthetic capacity of the leaves, and strengthen the tree
