At present, the peaches are basically harvested except for some very late-maturing varieties. Although the management work for one year has come to an end, do not neglect the management after harvesting. It is understood that during the period from the peach picking fruit to the deciduous period in October, the roots of the peach tree enter the growth peak. The management of this time is directly related to the growth results next year. Then, in October, what are the main points of management of peach trees? Let's take a brief look.
1, plastic trim
After picking fruit in October, the new shoots of peach trees grow faster. At this time, it is easy to cause poor ventilation in the sputum and affect the flower bud differentiation. Therefore, through scientific plastic trimming, it can improve the ventilation and light conditions, and enrich the branches, which is conducive to flower bud differentiation. It is recommended that the old weak branch group should be short-term retracted, and try to use the middle branch group to hang fruit. In addition, the weak branches of the drooping result should be properly retracted to promote their renewal and rejuvenation. In a nutshell, it is to go to the strong branch, to stay in the middle of the branch, to stay long and stay the result.
2, scientific fertilization
Fertilization should be divided according to the situation. Generally, early or early harvested orchards should be applied as early as possible, while late-maturing peach varieties should be fertilized before harvesting. The amount of fertilizer applied varies from tree to tree, especially for debilitating and old trees. Add post-harvest fertilizer. Generally, the fertilization amount of the high-yield tree is 2 to 3 times of the yield, and the groove or the annular groove is dug 50 cm away from the root of the tree. In addition, after harvesting, 0.4%-0.5% urea + 0.3%-0.5% potassium dihydrogen phosphate should be added once every two weeks to improve the photosynthetic capacity of the leaves.
3. Pest control
Common pests and diseases on peach trees in October include bacterial perforation, gum disease, aphids, leaf miner, and red spider. Usually, the disease can be treated with 70% methyl thiophanate WP 800-1000 times solution, 65% mancozeb WP 500 times solution, 50% carbendazim 800 times solution, etc., 10-15 days. Spray once. The insect pests can be treated with 3% polymycin-resistant 400-500 times solution or 25% chlorfenapyr No. 3 1500-2000 times solution.
4, drought prevention and drainage
In the autumn of October, there was more rain. On the basis of irrigation and drainage, combined with cultivating and weeding, the soil around the trunk was properly cultivated to prevent stagnant water in the tree tray.
In general, October is also a key node, and the peach farmers should pay extra attention to the various points and links. When all the management work is properly put in place, it will be able to lay a good foundation for the growth of peach trees in the coming year. basis.
