The Latest Management Techniques and Methods Tutorial for Yellow Peach Orchards
After planting yellow peaches, long-term maintenance and management are required, which involves a lot of work and careful care of the yellow peach trees. Different maintenance work and different management tasks are needed at different growth stages. At present, the main tasks are proper fertilizer and water nutrition management, pruning, as well as temperature and humidity control, ventilation and air permeability, and soil management. There is also the prevention and control of pests and diseases that harm the fruit trees. Please continue reading for the specific details.
1. Fertilizer and Water Regulation
The general fertilization principle is light fertilizer applied frequently, promote first and control later. Apply fertilizer multiple times before June, generally applying 50 grams of urea per tree at a time. 50 grams of monopotassium phosphate per tree, applying about three times. Yellow peaches are suited to slightly acidic soil, so ammonium bicarbonate must not be applied, as ammonium bicarbonate alkalizes the soil. During the growth period, magnesium and iron elements need to be supplemented, as they are easily deficient. Fertilization is greatest during the fruiting period, accounting for about 40% of the whole year's fertilization combined. Lower than base fertilizer. Nitrogen, phosphorus and potassium are used together for comprehensive fertilization.
2. Adjusting Pruning,
Yellow peaches have strong sprouting ability and branch-forming ability, so pruning must be done frequently during the growth period, mainly pruning water sprouts and overly dense branches, new shoots that are not retained, weak shoots, surplus shoots, and late autumn shoots that consume nutrients. For young trees, the main task is to establish form, leaving the main trunk, retaining enough side branches, keeping branches level by level, and removing surplus branches. In summer, when growth is vigorous, fruiting trees can have their shoots renewed, cutting away some old branches and keeping new shoots. If some growing side branches are too densely packed, they can be tied and pulled to open the angle. Remove basal buds and surplus buds. Winter pruning mainly clears dead branches and diseased and pest-infested branches, improves structure, and renews and rejuvenates the tree.
3. Fruiting Management
Yellow peaches have three physiological fruit drops, so buds must be removed to promote strong branches, and then additional fertilizer must be applied to maintain nutrition. Remove some branches and shoots to concentrate nutrient supply, thin the fruit, retain high-quality fruit at good nodes on strong branches, and also remove diseased fruit, mummified fruit, small fruit, and deformed fruit. For clustered fruit, retain one to two good fruit and remove the others. Spray growth regulators to retain fruit. After spraying fungicide, bag the fruit to protect it from pests and diseases.
4. Pest and Disease Control
The main disease is peach anthracnose, which mainly harms the fruit, forming lesions, causing rot and drop. In addition to timely pruning of diseased fruit and diseased branches, before germination spray a 5-degree Baume lime sulfur mixture mixed with 100-fold sodium pentachlorophenate solution to eliminate overwintering pathogens. During the disease period, spray an 800-fold solution of 80% anthracnose thiram or an 800-fold solution of 72% Dupont Curzate. The commonly occurring pest is the peach aphid, which pierces and sucks sap, causing sooty mold and spreading viral diseases. Set up yellow sticky boards in the orchard to lure and then kill the peach aphids. Spray a 1000-fold aqueous solution of 40% dimethoate emulsifiable concentrate or a 1000-fold aqueous solution of 40% acephate emulsifiable concentrate.
Regarding yellow peach orchard management, the main approach is to carry out different management according to tree age and different growth stages. The above is a detailed description of management after planting in a yellow peach orchard. Every period is important, but the fruiting period is still especially important.
