How to grow ultra-early red honey peaches? Detailed explanation of cultivation techniques

1. Tree shape and density: For open-field cultivation, the tree can be trained to a three-main-branch open-center shape or a free spindle shape, with suitable densities of 3 m x 4 m or 2 m x 4 m. For greenhouse cultivation, the tree can be trained to a free central-leader shape or an inverted "V" shape, with a suitable density of 2 m x 1 m.

2. Control the fruit load: This variety has a high fruit-setting rate, so thinning is essential. Begin thinning 10-15 days after flowering, leaving 3-4 fruits on long fruiting branches and 1 fruit on short fruiting branches. Generally, the fruit load per 667 sq m should be controlled at 12,000-15,000 fruits.

3. Fertilization by stages: Before bud break, apply 2-3 cubic meters of organic fertilizer per 667 sq m; during the fruit enlargement stage, apply 30 kg of diammonium phosphate; after fruit harvest, apply 40 kg of a three-element compound fertilizer; after leaf fall, apply 2-3 cubic meters of organic fertilizer. For foliar feeding, spray once a week from the fruit enlargement stage to the ripening stage.

4. Summer pruning: After fruit set, promptly prune out fruitless branches, upright vigorous branches, leafless fruiting branches and thin weak branches; during the young fruit growth period, remove vigorous growing branches on the outer part of the canopy; after harvest, promptly remove dense branches and old weak branches to improve light conditions in the tree.

5. Pest and disease control: Focus on controlling peach aphids and bacterial shot hole disease. Before peach trees bud break, spray 3-5 degrees Baume lime sulfur mixture to control overwintering pests and diseases. Before flowering and after petal fall, spray 10% imidacloprid 1500 times solution once each to control aphids. For bacterial shot hole disease, spray 70% thiophanate-methyl 800-1000 times solution at the early stage of the disease.
