Special slow release fertilizer for fruit trees

Abstract

The invention discloses special slow release fertilizer for fruit trees. The fertilizer is prepared from raw materials in parts by weight as follows: 50-100 parts of straw powder, 60-90 parts of livestock and poultry manure, 20-40 parts of plant ash, 20-40 parts of acrylic acid, 10-20 parts of diammonium hydrogen phosphate, 10-30 parts of monopotassium phosphate, 10-20 parts of calcium nitrate, 6-12 parts of monocalcium phosphate, 0.1-4 parts of polyacrylamide, 1-5 parts of amino acid, 1-7 parts of a compound microbial agent, 0.2-4 parts of cellulose and 1-5 parts of medium trace elements. Organic ingredients, inorganic ingredients and the microbial agent are mixed for use and all parts have a synergistic effect, so that the fertilizer has higher fertility and provides nutrition required for growth of the fruit trees.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special slow-release fertilizer for fruit trees. Background technique [0002] Fruits are rich in vitamins, minerals, cellulose and fructose, and they consume a large amount of food in people's daily life. They are equally important to food and vegetables in the human diet. The high quality of fruit trees is the goal that people are unremittingly pursuing. Effective use of limited land resources to improve the yield and fruit quality of fruit tree crops is the direction of people's efforts. [0003] Like other crops, the growth of fruit requires the application of nitrogen, phosphorus and potassium fertilizers, and it also needs to be rich in calcium, iron, sulfur, zinc and many other minerals and trace elements. During the growth process, most of the nitrogen elements need to be absorbed, and nitrogen fertilizer has an obvious effect on improving the yield of fruit trees....

AI Technical Summary

Problems solved by technology

Urea is a high-quality nitrogen fertilizer with high nitrogen content, fast fertilizer efficiency, and large dosage. However, during use, urea is easily lost through volatilization, leaching, decomposition, and runoff, resulting in low fertilizer efficiency. waste, and pollute the environment on which human beings depend, such as the atmosphere, water and soil

Most of the existing fruit tree fertilizers will cause drug residues, and many of them have strong toxic and side effects on the human body, and the cost is high and the production process is complicated.
