First, autumn Shi base fertilizer
After the rain, the soil is fully wet and then applied to the base fertilizer. The parallel ditch is opened at the drip line on both sides of the tree. The organic fertilizer or bio-organic fertilizer such as Shiyuanlin brand is 3-5 kg, and the ditch cover covers the soil layer 5-10 cm.
Second, plastic trim
It is advisable to use a natural evacuation layered tree type, and the pruning principle is to separate and emphasize. For overlapping, co-existing, cross-competing, and competing branches, the poorer ones are removed, and the diseased branches, dead branches, and weak result branches are cut off. After pruning, the callus and anti-corrosion film should be used in time to protect the wound healing tissue growth, anti-corrosion pathogen infection, anti-soil, rainwater pollution, anti-freeze, anti-shock crack, to reduce nutrient consumption, improve flower quality and fruit set rate.
Third, pest control
In the autumn, spray an anti-insect treatment agent, combine foliar fertilizer, promote flowers and so on. In the dormant period of the deciduous period, spray the tree to protect the generals and completely eliminate the source of the wintering pests.
Fourth, prevent premature defoliation
At the same time of pest control, the drought should be properly irrigated, and the leaf surface should be sprayed with a new high-fat film to prevent leaf virus infection, prevent premature leaf detachment, and affect the normal fruit quality and quality improvement next year.

Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.
