Nucleation-free yellow skin post-harvest management
The seedless yellow-leaf harvest period is in the middle or late July. How to manage the result tree after fruit harvesting will directly affect the yield and quality of the next year. Autumn shoots are the result of the yellow branches, and the quality of autumn shoots will inevitably affect the number and quality of flower buds. In order to lay a solid foundation for the production of high yields in the following year, and cultivate strong autumn shoots, the following tree management measures can be taken for the result tree after fruit harvesting: 1. Trim and wipe the fruit immediately after fruit harvesting. Promote the neat budding. Short truncate the resulting mother shoots, cut off the fruit spikes at the top of the resulting shoots, remove dead branches, diseased shoots, and weak branches; carry out proper shaping of the tree body, such as by pressing the top sunroof, pruning the bare shoots, and removing the overlying branches. Tip, forming a good round-headed tree. After pruning for about 10 days, that is, before and after the beginning of autumn, shoot shoots begin to sprout. Autumn shoots, especially shoots that have been treated with short cuts, have two buds at the top, and all others are erased, which helps to concentrate nutrients. Strong and strong. 2. Fertilizer and water management Immediately after the harvest, apply the shooter fertilizer to the result tree, apply 40 kg of biogas slurry per plant or 40 kg of rotten peanut bran manure to the result tree. 40 kg plus 1 kg each of superphosphate and potassium sulfate. Sprinkle the fertilizer as much as possible in the tree tray, which will help the root system absorb evenly and prevent the loss of water and fertilizer. The first autumn shoots must be cooked in early September. The late mature shoots of late autumn must be no later than the beginning of November. After the late autumn shoots are formed, water fertilizers should be banned to prevent the winter shoots from falling out. Pay attention to the supply of water during the cultivation of autumn shoots, especially in the buds and during droughts, and often spray water to keep the soil moist. III. Pest Control The common pests and diseases of seedless yellow hull include: anthracnose, leaf leaf moth, papilio larvae, white moth, wax cockroach, cockroach, and other long-lived cattle. Leafminer and Swallowfly larvae. Can be used to control 1000 times or worms 2000 times. White moth wax moth can be culled 800 times faster. Spawning on the shoots results in the death of autumn shoots, and the insects' eggs are burned in time. Tenguin is the main branch of the trunk. When it is found in the stem of the cow, it can be injected into the insect tract with a solution of dipterex or blocked with a solution of cotton vinegar. During the rainy days, young shoots are very susceptible to anthrax, and 1000 times more sensible manganese zinc is sprayed before the rain. After rain, it is treated with thiophanate-methyl or chlorothalonil 1000 times spray. 4. Control of winter shoots Winter warm weather can easily induce winter shoots. Winter shoots are bound to consume autumn shoot nutrients and affect flower bud differentiation. Therefore, the formation of winter shoots must be strictly prevented. The control methods of winter shoots are as follows: in combination with the foundation fertilizer for winter opening, the roots of the sun are used to control the water, so that the tree roots are controlled in a certain state of drought, and the tree is forced to sleep; the other method is to use 0.15% of the autumn shoots. Paclobutrazol, sprayed three times at intervals of 20 days, can effectively inhibit the formation of winter shoots. China Agricultural Network Editor
