Organic-inorganic compound fertilizer for pears

Abstract

The invention discloses an organic-inorganic compound fertilizer for pears. The compound fertilizer is prepared by blending, by mass, 28-30 parts of ammonium sulfate, 3.5-4 parts of diammonium phosphate, 18-20 parts of potassium chloride and 48-50 parts of organic fertilizer. The invention also discloses application of the organic-inorganic compound fertilizer for pears. An application method includes the steps that in 40-60 days after pear blossom, the compound fertilizer is applied by the adoption of a hole fertilization method, and the application amount is 0.8-1.2 kg per tree, wherein the hole fertilization method includes the steps that 8-10 holes are dug in the positions 1.5-2.5 m away from the center of a trunk, and the depth of each hole is 30-50 cm. The organic-inorganic compound fertilizer for pears is reasonable in fertilization-nutrient distribution ratio, meets the nutrient requirements of pears, and especially satisfies the potassium requirement during a fruit swelling period of pears. The use ratio of the compound fertilizer is high, and the compound fertilizer can achieve double effects of improving the yield and the quality of pears. Meanwhile, the adverse effect of improper fertilizer usage on environment is reduced, and the soil of pear orchards can be improved by long-term application.

Description

technical field [0001] The invention belongs to the technical field of fertilizers and relates to a special organic-inorganic compound fertilizer for pear trees. Background technique [0002] There are many types and varieties of pears in our country. Among them, Huangguan pear and Fengshui pear are high-quality varieties developed in my country in recent years. Their flesh is delicate, the shape of the fruit is correct, and their flavor is unique. There are large areas of cultivation. Fertilizer is one of the most important material bases in pear production. Reasonable fertilization is not only related to the improvement of pear yield and quality, but also affects the soil fertility and economic benefits of orchards. [0003] Pear tree fruit has a large demand for nutrients during the fruit expansion period, especially the absorption of potassium is greater than the absorption of nitrogen and phosphorus. The problem of potassium fertilizer ignores the input ratio of nitrog...
