Look at the tree
Look at the size of the peach tree, the strength of the growth and the amount of production. A combination of root application and foliar application is generally employed. For mature trees, 0.4-0.6 kg of compound fertilizer is applied per plant according to the fertilization period, so as to continue to supplement nutrition. For example, after flowering, the main effect is the quick-acting nitrogen fertilizer, and the leaf surface is sprayed with boron; for example, the top dressing before harvesting is based on the quick-acting potassium; if the fertilizer is taken, it can be used in September-October after harvesting. The main application of nitrogen fertilizer, combined with phosphate fertilizer.
Look at the ground
Look at the structure and fertility of the soil to determine the type, quantity and method of topdressing. For example, sandy soil, low organic matter content, poor structural performance, and serious water leakage and leakage, the peach trees growing in this soil, 60 kg of high-quality ring fertilizer per plant, mixed with 0.4-0.6 kg of fertilizer.
Look at production
Look at yield fertilization. The resulting large amount of trees must have sufficient fertilizer and a reasonable mix of nitrogen, phosphorus and potassium to keep the length of the extended branch at 1.0-1.5 cm. Under normal conditions, for every 100 kilograms of peach produced, it can be used for 0.7-0.8 kg of quick-acting nitrogen fertilizer, 0.5-0.6 kg of phosphate fertilizer, and 1-1.5 kg of potassium fertilizer.
