1. An orchard with a yield of more than 4,000 kilograms per mu: organic fertilizer 3 to 4 m3/mu, nitrogen fertilizer (N) 25 to 30 kg/mu, phosphorus fertilizer (P2O5) 8 to 12 kg/mu, potassium fertilizer (K2O) 20 to 30 kg/mu. 2. Orchards with an output of 2,000 to 4,000 kilograms per mu: organic fertilizer 2 to 3 m3/mu, nitrogen fertilizer (N) 20 to 25 kg/mu, phosphorus fertilizer (P2O5) 8 to 12 kg/mu, potassium fertilizer (K2O) 20 to 25 kg /mu. 3. Orchards with a per mu yield of 2,000 kg or less: organic fertilizer 2 to 3 square meters/mu, nitrogen fertilizer (N) 15 to 20 kg/mu, phosphate fertilizer (P2O5) 8 to 12 kg/mu, potassium fertilizer (K2O) 15 to 20 kg/water mu.
In the orchards with less calcium and magnesium in the soil, phosphate fertilizer should be used for calcium, magnesium and phosphate; orchards with iron, zinc, and boron deficiency can be sprayed with foliar ferrous sulfate at a concentration of 0.3% to 0.5%, zinc sulfate at 0.3%, and 0.2%. % to 0.5% borax to correct. According to the application amount of organic fertilizer, the amount of fertilizer N and K may be increased or decreased as appropriate. All organic fertilizers, all phosphate fertilizers, 50% to 60% nitrogen fertilizers, and 40% potassium fertilizers were used as base fertilizers in autumn after pear fruit harvest. The remaining 40% to 50% nitrogen fertilizers and 60% potassium fertilizers were in the bud stage in March. And during the expansion period from June to July.
