Management Techniques of Yellow Peach Orchard

After planting, yellow peach needs long-term maintenance and management, which requires a lot of work and careful care of yellow peach fruit trees. Different maintenance work and different management tasks are needed in different growth periods. At present, the main thing is to do a good job in fertilizer and water nutrition management, pruning, temperature and humidity control, ventilation and soil management. There is also the prevention and control of diseases and insect pests that harm fruit trees. Please continue to read the details.

1. Fertilizer and water regulation

The general principle of fertilization is to apply thin fertilizer frequently, promote before and control after, fertilize many times before June, generally apply 50 grams of urea at a time. Potassium dihydrogen phosphate is 50g per plant and fertilized for about three times. Yellow peach is suitable and slightly acidic soil, so ammonium bicarbonate and ammonium bicarbonate can not be applied to alkalize the soil. Magnesium and iron should be supplemented during the growth period, which is easy to lack. The fertilization in the fruit period is the most, which together accounts for about 40% of the fertilization in the whole year. Lower than base fertilizer. Nitrogen, phosphorus and potassium are used together to fertilize comprehensively.

2. Adjust pruning,

Yellow peach has strong sprouting and branching ability, so it should be pruned frequently during the growth period, mainly pruning long branches, over-dense branches, unretained new shoots, weak shoots, extra shoots, and late autumn shoots that consume nutrition. Young trees are mainly qualitative, set aside the trunk, retain enough lateral branches, leave branches step by step, and remove the excess branches. When it grows vigorously in summer, the fruiting tree can change its shoots, cut off some old branches and leave new ones. Some growing lateral branches are so dense that they can be pulled and opened at an angle. The basal buds were removed and the redundant buds were removed. Winter repair is mainly to clean up dead branches, disease and insect branches, improve structure, renew and rejuvenate, and so on.

3. Result management

Yellow peach has three physiological fruit drops, so it is necessary to wipe buds to promote strong branches, and then to fertilize and maintain nutrition. Remove some branches, concentrate on nutritional supply, thinning fruit, retain good nodes on strong branches of high-quality fruit, but also diseased fruit, stiff fruit. Small fruit and abnormal fruit are all removed. The cluster fruit retains one or two good fruits and the others are removed. Spray growth regulators to protect fruit. After spraying fungicide, bagging protects the fruit from diseases and insect pests.

4. Disease and pest control

The main disease is peach anthracnose, which mainly harms the formation of disease spots, decay and shedding of the fruit. In addition to pruning diseased fruit branches in time, it is necessary to spray 5-Bomedo stone-sulfur mixture mixed with 100-fold pentachlorophenol sodium solution before germination to eliminate overwintering bacteria. Spray 80% anthrax 800 times solution or 72% DuPont Krou 800 times solution during the onset of the disease. The common pest is that peach aphids prick and suck juice to cause coal fouling disease and spread viral diseases. Yellow boards are set up in the park to lure peach aphids and then kill them. Spray 1000 times of 40% dimethoate EC or 1000 times of 40% acephate EC.

On the yellow peach orchard management, mainly according to the fruit tree age and different growth periods to carry out different management, the above is a detailed description of the yellow peach garden after planting management, each period is very important, but the fruit period is still particularly important.
