Summer pear tree skillful fertilizer

The summer is the period when the pear tree has the largest amount of vegetative growth and the fastest reproductive growth. At this time, pears have higher requirements for fertilizer and water conditions, and they should do a good job in the top dressing.

Dressing: Before pear flower bud differentiation, topdressing applies phosphorus and potassium as the main, and nitrogen supplements the special fertilizer for fruit trees. According to the age of the tree and the number of results, the strain applies 1 to 1.5 kilograms and is immediately filled with water after application. Combined with spraying, the tree was sprayed with 1 to 2 times 0.3% amino acid compound fertilizer. In July, after the early maturing varieties were harvested, a quick-release nitrogen fertilizer was applied immediately to supplement the lack of nutrients caused by the results. For late-maturing varieties, phosphorus and potash fertilizers should be topdressed at this time.

Outside the root dressing: When the tree needs a certain amount of nutrient elements in a certain period and the root is absorbed and difficult to meet, or the soil lacks a certain kind of element, the foliar spray fertilizer can be applied, and spray spraying can also be performed. Fertilizers that are generally soluble in water can be used as top-dressing fertilizers. Commonly used concentrations are 0.3% to 0.5% urea, 0.5% superphosphate, 0.5% potassium sulfate, 0.5% potassium dihydrogen phosphate, 0.3% borax, and sulfuric acid. Iron 0.05% to 0.1%, zinc sulfate (post-emergence) 0.1 to 0.4%, (before germination) 1% to 5%. When mixing or at sunny hot temperatures, the concentration is slightly lower.

Interplanting green manure: In the young garden, intercropping can be used for planting leguminosae, milk vetch or purple ryegrass for green manure. Sow in the middle of September sowing, applying 5 kg of calcium magnesium phosphate fertilizer, potassium sulfate, and ammonium molybdate per acre. In mid-June and late summer, when the summer drought occurs, the yield per acre is about 500-1000 kg, which is used as a sapling summer cover and fertilizer.
