I. Clear Garden Peach trees should be cleared in time after picking, and the rotten fruit, disease and fruit, fallen leaves, and weeds in Taoyuan should be cleared and buried in order to eliminate the transmission of pests and diseases. Second, the cultivator After the fruit is harvested, the cultivator loosens the soil in a depth of 10-15 cm. Third, fertilizer and water management 1. Top dressing. Peach trees consume a lot of tree nutrients during fruit growth, lack of nutrients in the body, and need timely nutrition supplements to restore the tree vigor. In the vertical projection of the canopy along the excavation of shallow ring ditch, strains of urea 1 kg, ammonium bicarbonate 2 kg and appropriate amount of phosphorus and potassium fertilizers. You can also spray foliar fertilizers, such as 1% urea solution, 0.2% potassium dihydrogen phosphate solution, to extend the period of leaf culture, and accumulate more nutrition. 2. Apply base fertilizer. Basal fertilizer is mainly farm organic fertilizer with full maturity, supplemented by ternary compound fertilizer, with the trunk as the center, 35 to 40 centimeters from the trunk, 4 to 8 radial sewers digging, nearly 15 to 20 centimeters deep at one end, and the far end 35 to 40 cm deep, per acre Shi quality and good quality ring fertilizer 4000 kg + potassium sulfate 30 ~ 40 kg, irrigation after fertilization. 3. Watering. Peach generally receives more rain after harvesting, but it is not necessary to water. If the drought is too long, water may be used to make up for it. During the rainy season, the water should be drained and flooded, and the frozen water should be poured before the soil is frozen. Fourth, timely pruning 1. To clear away dense branches, leave 1 to 2 secondary shoots on the Zhuangzhi branch, and cut off 35 to 40 cm in length without the auxiliary tip. The lignification shoot should be light cut. The long-term result of the unbridled branch, Wang branch topping. 2. Cut two or three of the reserve branches at the base. Twisted, pressed, and pulled Wang Tzu at the time of last year's winter shear can be shrunk at the base tip, or cut at the bending tip, and then topping the tip. 3. Update and rejuvenate the weaker middle and small branch groups and horizontal drooping branches. Remove the upright, dense and diseased shoots from the Wangzhi group. Where there is space, 15-20 cm short cuts may be left. V. Prevention of pests and diseases The main pests and diseases after peach harvesting are bacterial perforation, aphids, leaf miners, red spiders, and turbid fluids. 1. Bacterial perforation. To be prevention-oriented, from the beginning of June, foliar spray zinc sulfate lime solution, the ratio of zinc sulfate: quick lime: water according to the ratio of 0.5:2:12, every 15 days, a total of 4 to 5 Times. 2. Locusts. It can be treated with 10% imidacloprid 3000 times or 5% acetamiprid 1500 times. 3. Red spider. Can be used 1.8% avermectin 3500 times or 20% Fuling 1500 times liquid control. 4. Leaf miner. Can be used 25% diflubenzuron 3 1000 times solution. 5. Flow gum disease. One is to try to avoid the branches from mechanical damage; the second is to remove the glue from the branches, use 10 parts of quick lime, 1 part of lime sulfur, 2 parts of salt, and 0.3 parts of vegetable oil and add proper amount of water. , smear the affected area or cut the mouth can be. 6. Pear borer. It can be controlled with 4.5% beta-cypermethrin 2000 times solution or Methionine 4000 times solution.

Peach tree after fruiting management mo relax
Peach fruits have gradually entered the harvesting period. Some fruit growers loosen their management of peach trees after fruit picking, and some do not even manage them. This will be detrimental to the growth of peach trees and the high yields of the next year. After the peach tree results, a lot of nutrients were consumed. After peaches were picked, it was a critical period for peach nutrient accumulation and flower bud differentiation. At this time, the management was strengthened to increase the nutrient accumulation of the tree body and restore the tree vigor as soon as possible so that the tree body formed good flower buds. , In order to increase the peach production and quality in the coming year, create favorable material conditions. The post-harvest management measures are as follows:
