Water chestnut gardens with water sources should be watered in time. Relying on natural rainfall, the tree trays should be trimmed in time to ensure the water for the later growth and nutrient accumulation of chestnut trees, and lay a good foundation for next year's production. Loosen the soil in time to cultivate the soil of the chestnut garden, and bury the weeds in the projection range of the canopy shallowly, in order to loosen the soil and increase soil organic matter. Generally combined with basal fertilizer application, the depth is generally 20 to 30 cm. Note that the outer periphery of the crown should be deep and the surrounding of the trunk should be shallow during cultivating. When turning the soil, purposely damage a small part of the root system in order to make new roots and enhance the absorption of fertilizer and water. Pruning and shaping the number of parent branches on chestnut trees and their strength are important indicators that determine the yield of the coming year. The main purpose of pruning is to make the chestnut tree's inner and outer parts, upper and lower parts to be able to produce strong fruiting branches, make full use of space, try to increase the fruiting parts, prevent the branches outside the crown from being too dense and high, and to ensure that the inner chamber is ventilated. Light. All the slender branches and male flowering branches that are too dense should be thinned out, and a small part of the branches should be shortened to cultivate strong newer branches to lay the foundation for the next year. Following the principle of pruning should be early but not late, light and not heavy, cut off diseased branches, dead branches, overlapping branches, thin branches and hanging branches, and the cut branches should be taken out of the orchard for other treatment or burnt. Disease and pest control After picking fruits, attention should be paid to clear the garden in time, cut off dead branches and branches with serious diseases and insects, and remove the branches and leaves that fall off the ground, and burn them or bury them.

How to manage chestnut after harvest
After fertilization, spray foliar fertilizer or root fertilization as soon as possible after harvesting to restore tree vigor, enhance leaf photosynthetic capacity, and ensure sufficient nutrients for flower bud differentiation. Foliar fertilizer can be 0.3% potassium nitrate, potassium dihydrogen phosphate, urea liquid, etc. It is required to spray in the morning and evening, and spray evenly on the surface and back of the blade. Root fertilization is generally 500-750 grams of urea and 200-300 grams of potash fertilizer. Add organic fertilizer after falling leaves in late Autumn. Use strip furrow application, circular furrow application, and radial furrow application, and apply 1,000 to 2000 kg of organic fertilizer per mu.
