High-yield mango post-harvest management technology
The measures to increase mango yield in the next year should start from post-harvest management
The management of mango trees after harvesting is directly related to the annual mango yield and must be strengthened. Therefore, it is necessary to pruning and controlling pests and diseases in time after harvesting, in order to restore the tree potential, increase nutrient accumulation, and reduce the wintering base of pests and diseases, laying a foundation for the next year's flowering results and stable yield and high yield.
After harvesting fruit, it is necessary to fertilize early, and the plastic trimming work should be completed as soon as possible to prevent the earing time from being affected too late. The results of many trees should leave more leaves and lightly cut, and the trees with fewer results should be thinned or retracted according to the density of the canopy. Weak trees should be reserved with more mutual help branches, so that the green leaves of the canopy are balanced, and then the excess branches are removed. After pruning, the wound should be sterilized and sealed with "healing anti-corrosion film" in time to prevent rain and soil pollution and pathogen infection, and induce various pests and diseases. The other pruned diseased leaves and diseased branches should be taken out of the garden and destroyed centrally; the tree body lesions are scraped off with a knife, and then the "tree guard general" emulsion is applied to the lesions to quickly dry and peel off the skin. The source of the bacteria; then the whole garden sprays the "tree guard general" Qingyuan disinfection to prevent the spread of pests and diseases, heat preservation and antifreeze.
The large and small phenomenon of mango trees seriously affects their yield and quality. The use of ring-fed supporting “foliar fertilizer†to promote and control technology can effectively control the phenomenon of large and small. Specific method: At the end of autumn, the mango tree trunk is cut in a smooth place. The tree is strong and can be cut in two loops. If the tree is weak, it can be cut in a circle, the slit is 1.5 mm wide, and then the "leaf" is applied at the slit. "Face fertilizer", disinfection activity, control the shoot to promote flowers, improve the fruit set rate, do not harm the tree, eradicate the phenomenon of large and small.
