Carbon-vinegar slow-release biological fertilizer and application thereof

Abstract

The invention discloses a carbon-vinegar slow-release biological fertilizer, and a preparation method and application thereof. The carbon-vinegar slow-release biological fertilizer comprises the following components in percentage by weight: 0-50% of urea, 1-20% of calcium ammonium nitrate, 3-30% of potassium nitrate, 0-20% of potassium carbonate, 4-40% of ammonium phosphate-nitrate, 0-20% of monoammonium phosphate, 3-30% of diammonium phosphate, 0-10% of double superphosphate, 0-25% of potassium chloride, 3-30% of potassium sulfate, 0-10% of ammonium chloride, 0-10% of ammonium sulfate and 2-5% of microelement. The carbon-vinegar slow-release biological fertilizer is characterized by also comprising the following components in percentage by weight: 20-50% of organic carbon and 4-12% of vinegar. The preparation method comprises the steps of slow-release granular fertilizer preparation, nutrient analysis and preparation. The application is the application of the carbon-vinegar slow-release biological fertilizer in preparation of a vegetable fertilizer and / or improvement of soil fertility. 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 biotechnology, and further belongs to the field of biofertilizer technology, in particular to a charcoal vinegar slow-release biofertilizer and its preparation method and application. Background technique [0002] Crops need to absorb more nutrients in a growth cycle, not just nitrogen, phosphorus, and potassium provided by ordinary fertilizers. According to the short board theory of wooden barrels, if there is a lack of other nutrients, they will not be able to grow and develop normally, and the plants will be thin and small, and the heading will not be good. 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,...

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, low temperature, soil fertility, and soil structure. Therefore, it is very necessary to develop a slow-release bio-fertilizer that saves costs, is simple to prepare, and is economical and environmentally friendly. of
