Summer is the period of the largest vegetative growth and the fastest reproductive growth in pear trees in a year. It is also a period when the amount of fertilizer needed is very high. The pear trees require higher fertilizer and water conditions. How do fertilization in summer pears? Soil top dressing In June, before the flower bud differentiation of pear trees, a special fertilizer for fruit trees supplemented by phosphorus and potassium and supplemented by nitrogen was applied. According to the age and the result of the tree, the plant was applied 1 to 1.5 kg, and immediately after application. In combination with spraying, the tree is sprayed with 1 or 2 times of 0.3% amino acid compound fertilizer. In July, after the early maturing varieties were harvested, a quick-acting nitrogen fertilizer was applied immediately to supplement the nutritional deficiency caused by the results. For mid-late maturing varieties, phosphorus and potassium fertilizers should be applied once at this time. Top dressing When the tree body needs a certain nutrient element in a certain period of time and the root system absorbs it and is difficult to satisfy, or when the soil lacks a certain element, foliar spray fertilizer can be carried out, and it can also be combined with spraying. Fertilizers that are generally soluble in water can be used as top dressings. Common concentrations are: urea 0.3% to 0.5%, superphosphate 0.5%, potassium sulfate 0.5%, potassium dihydrogen phosphate 0.5%, borax 0.3%, sulfuric acid Iron is 0.05 to 0.1%, zinc sulfate (after germination) is 0.1 to 0.4%, and (before germination) is 1 to 5%. When mixing or when it is hot or hot, the concentration is slightly lower. Interplanting green manure In the young garden, it can be used as a green manure for the legumes of the leguminous family, the milk vetch, or the ryegrass of the grass family. Sowing in mid-September, 5 kg of calcium magnesium phosphate, potassium sulfate and ammonium molybdate per acre. In the middle and late June of June, the summer will be castrated before the onset of drought. Generally, the yield per acre is about 500-1000 kg, which is used as a summer cover and fertilizer for young trees. Precautions Before the flower bud differentiation from May to June, a special fertilizer for fruit trees supplemented by phosphorus and potassium as the main nitrogen is applied. According to the age and the result of the tree, the soil plant is applied 1 to 1.5 kg, and the water is immediately poured after fertilization. Combined with spraying, the tree is sprayed with 3% amino acid compound fertilizer 1 or 2 times. Immediately after harvesting the early maturing varieties, a quick-acting nitrogen fertilizer is applied to supplement the lack of fertilizer caused by the results. For mid-late maturing varieties, phosphorus and potassium fertilizers should be applied once at this time. After fertilization, water should be properly irrigated according to soil moisture.
