Special charcoal vinegar slow-release bio-fertilizer for fruit trees and preparation method thereof

Abstract

The invention discloses a special charcoal vinegar slow-release biological fertilizer for fruit trees and a preparation method thereof. The special charcoal vinegar slow-release biological fertilizer for fruit trees comprises 18-20% by weight of urea, 1-3% of potassium nitrate, diammonium phosphate 20~25%, potassium sulfate 15~20%, potassium chloride 12~20%, trace elements 2~5%, also includes organic carbon 20~30% by weight, vinegar 8~10%. The preparation method includes preparation of slow-release granular fertilizer, nutrient analysis, and preparation steps, specifically including pulverizing each prepared raw material fertilizer and organic carbon, and the weight ratio of each raw material fertilizer to organic carbon is 50-80:20-50 Mix the raw materials, then spray 13~98‰ of the weight of each raw material with vinegar solution for mixing, stir evenly, granulate, granulate, and dry to obtain various slow-release granular fertilizers; according to the analysis of soil nutrients and crop characteristics The final analysis and inspection report; according to the group ratio, the special charcoal vinegar slow-release bio-fertilizer for the target fruit tree is obtained. The preparation method of the invention is simple, economical and environment-friendly, and the economic benefit is improved while reducing the production cost.

Description

Technical field [0001] The present invention belongs to the field of biotechnology and further belongs to the field of biological fertilizer technology, which involves a kind of slow -release biological fertilizer and its preparation methods. Background technique [0002] In a growth cycle of fruit trees, more nutrients need to be absorbed, not just nitrogen, phosphorus, and potassium provided by ordinary fertilizers. According to the short board theory of wooden barrels, if other nutrients lack other nutrients, they cannot grow and develop normally.Qi, low pollution rate, seriously affects yield.At present, due to the significant increase in production of chemical fertilizers, it is used in large quantities, resulting in pollution and inferiority of soil texture, and natural ecological conditions are damaged.In particular, the use of fertility is low, which not only wastes resources, but also pollutes the environment. [0003] Fertilizer is a nutritional element necessary for fr...

AI Technical Summary

Problems solved by technology

At present, slow-release fertilizers at home and abroad are generally fertilizers that prolong the fertilizer effect through physical methods such as coating, wrapping, encapsulation, and coating, and wrapped fertilizers formed by mixing instant fertilizers with rubber emulsion and industrial and agricultural waste. , these fertilizers are expensive, and do not have the characteristics of rich voids, strong adsorption capacity, increased low temperature, increased soil fertility, and improved soil structure. necessary
