Abstract

The invention discloses fruit tree special purpose fertilizer and a preparation method thereof. The fruit tree special purpose fertilizer comprises particle compound fertilizer and a coating layer. The particle compound fertilizer comprises, by weight, 45-50 parts of urea, 6-10 parts of potassium chloride, 6-10 parts of potassium sulfate, 13 parts of nitric nitrogen, 11 parts of ammonium nitrogen,11 parts of diammonium phosphate, 0.7 parts of magnesium sulfate, 0.3 parts of calcium carbonate, 0.5 parts of boric acid and 0.5 parts of zinc sulfate. The preparation method comprises A, synthesisof a coating liquid, B, granulation, C, coating and D, drying. The fruit tree special purpose fertilizer contains comprehensive nutrients, has excellent sustained release performances, fully satisfiesthe nutrient needs of fruit trees, maximizes effectiveness of fertilizer, improves a fruit yield and fruit quality and is suitable for fruit tree planting.

Description

Technical field [0001] The invention relates to a fertilizer, in particular to a special fertilizer for fruit trees and a preparation method thereof. Background technique [0002] Fruits are rich in vitamins, minerals and fructose. In daily life, people often eat some fruits to supplement the nutrition needed by the human body, ensure the health of the human body, and eat a large amount of food. They are equally important in human dietary institutions with food and vegetables. There is a clear upward trend in production and planting area. The economic benefits of fruit trees depend on the output and production costs of the fruit trees. The high quality of the fruit is the goal that people are pursuing unremittingly. The effective use of limited land resources is the direction of people's efforts to improve the yield and fruit quality of fruit tree crops. However, in the cultivation of fruit trees, due to the insufficient fertility of the planting soil and serious pests and disea...
