Special carbon-vinegar slow-release biological fertilizer for fruit trees and preparation method thereof

Abstract

The invention discloses a special carbon-vinegar slow-release biological fertilizer for fruit trees and a preparation method thereof. The special carbon-vinegar slow-release biological fertilizer for fruit trees comprises the following components in percentage by weight: 18-20% of urea, 1-3% of potassium nitrate, 20-25% of diammonium phosphate, 15-20% of potassium sulfate, 12-20% of potassium chloride, 2-5% of microelement, 20-30% of organic carbon and 8-10% of vinegar. The preparation method comprises the following steps: slow-release granular fertilizer preparation: respectively pulverizing prepared raw material fertilizers and organic carbon, mixing the raw material fertilizers and the organic carbon in a weight ratio of (50-80):(20-50) to obtain raw materials, spraying vinegar which accounts for 1.3-9.8 wt% of each raw material, uniformly mixing, granulating, finishing, and drying to obtain various slow-release granular fertilizers; nutrient analysis: making an analytical inspection report after analyzing the soil nutrients and crop characteristics; and preparation: preparing the target special carbon-vinegar slow-release biological fertilizer for fruit trees according to the component proportioning. The preparation method disclosed by the invention is simple, economic and environment-friendly, lowers the production cost, and enhances the economic benefit.

Description

technical field [0001] The invention belongs to the field of biological technology, further belongs to the technical field of biological fertilizer, and in particular relates to a slow-release biological fertilizer for fruit trees and a preparation method thereof. Background technique [0002] Fruit trees need to absorb more nutrients in a growth cycle, not just nitrogen, phosphorus, and potassium provided by ordinary fertilizers. According to the theory of short boards of wooden barrels, if there is a lack of other nutrients, they will not be able to grow normally, and the plants will be thin and small. Qi, pollination rate is low, seriously affecting yield. At present, due to the significant increase in production of chemical fertilizers and the large-scale use of them, the soil texture is polluted and deteriorated, and the natural ecological conditions are destroyed. In particular, the utilization rate of fertility is low, which not only wastes resources, but also pollut...

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
