Fertilizing method for improving fruiting rate of apple

Abstract

The invention relates to a fertilizing method for improving fruiting rate of apple and belongs to the technical field of crop planting. The fertilizing method comprises the following steps: 1), after harvesting of apple, furrow applying farm manure in autumn, 100 kg per plant, and adding powdered topsoil after the application; 2), furrow applying a compound fertilizer before and after Qingming, 1 kg per plant; 3), applying an algal solution in a germination stage after Qingming, 50 kg per plant; 4), heavily applying nitrogen fertilizer and potassium fertilizer in an enlargement stage, and applying 40 kg of the algal solution and 150 g of a mixed solution of potassium fertilizer containing 50 % potassium sulfate. Compared with the prior art, the fertilizing method may provide a great deal of apple tree required nutrition, promoting the growth of flowers and buds and effectively improving fruiting rate, each apple plant can produce 50-80 kg in the initial production stage and produce 150-220 kg in the high yield stage; each produced apple is large and uniform, has pure color, is crispy and sweet, and has high moisture content and rich nutrition.

Description

technical field [0001] The invention relates to a fertilization method for improving the fruit-setting rate of apples, and belongs to the technical field of crop planting. Background technique [0002] Apples are rich in sucrose, protein, fat, copper, iodine, manganese, zinc, phosphorus, iron, potassium, malic acid, quinic acid, citric acid, tartaric acid, tannic acid, pectin, cellulose, B vitamins, vitamin C, is a low-calorie alkaline food, the crown of the world's four major fruits (apples, grapes, citrus and bananas); the nutrients in apples are highly soluble and easily absorbed by the body, so they are called "living water". It is good for dissolving sulfur, making the skin smooth and tender, and the flesh is crisp and sweet, which is very popular among people. At present, the fruit-setting rate of apple trees is not high, so it is of great significance to study how to increase the fruit-setting rate of apples and increase the economic income of fruit farmers while mee...
