Low-yield orchard fertilization is mainly based on a large amount of farmyard manure, and at the same time, it is combined with fertilizers such as nitrogen, phosphorus and potassium. Focus on four fertilizations: The germination fertilizer is mainly nitrogenous fertilizer, supplemented by phosphorus and potassium, and appropriate amount of micro-fertilizer such as boron and zinc is applied, and it is applied about 10 days before the spring germination. Flower bud differentiation fertilizer is mainly composed of compound fertilizer and phosphate fertilizer with low nitrogen content. When most new shoots are stopped in late May, they are applied. The fruit expanded fertilizer is mainly potassium fertilizer, and combined with the application of compound fertilizer with low nitrogen content, it is applied from mid-July to mid-August. Nutrient reserve fertilizer (base fertilizer) is mainly based on farmyard manure, with a small amount of nitrogen and phosphate fertilizer applied, and is applied from late September to October (nitrogen fertilizer must be applied in time after fruit picking to avoid affecting fruit coloration). Each time the fertilization is combined with a suitable amount of water, the amount of fertilizer applied and the type of fertilization are adjusted according to the nutritional status of the tree at that time, the strength of the tree, and the ability of the soil to be fertilized.
