Problems solved by technology

At present, synergistic fertilizers at home and abroad are fertilizers that prolong the fertilizer effect through physical and chemical methods such as coating, wrapping, encapsulation, and coating, and combine instant fertilizers with polyvinyl alcohol, urea-formaldehyde, sulfur, alkyd resins, and polyurethane resins. Coated or coated fertilizers formed by the reaction of high molecular polymers, these fertilizers not only have high cost of coating, are difficult to degrade, but also have negative effects on the environment, thus limiting their application

Abstract

The invention discloses composite microbial multi-element film coating synergistic fertilizer and a preparation method thereof. The composite microbial multi-element film coating synergistic fertilizer is prepared from the following raw materials in parts by weight: 100 parts of particle fertilizer cores, 2 to 3 parts of film coating agents and 1 to 3 parts of composite microbial bacterial agents.The particle fertilizer cores are prepare from urea, ammonium sulphate, monoammonium phosphate, triple superphosphate, potassium chloride, monopotassium phosphate, ammonium molybdate, magnesium sulfate, fermentation fertilizer, bentonite, gamma-polyglutamic acid / chitooligosaccharide hydrogel; the film coating agents are prepared from urea, formaldehyde, alpha-methyl glucoside and diethylenetriamine pentaacetic acid; the composite microbial bacterial agents are prepared from bacillus subtilis, bacillus lateraporus and trichoderma viride. The composite microbial multi-element film coating synergistic fertilizer has the excellent performance that the nutrition is comprehensive; the fertilizer effect is good; the soil microenvironment is obviously improved; the soil quality is improved; the hardened soil is loosened. The fertilizer belongs to the fertilizer meeting the requirements of fertilizer reduction, effect enhancement and green and environmentally friendly effects.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a composite microbial multi-element coating synergistic fertilizer and a manufacturing method thereof. Background technique [0002] Due to the application of a large amount of chemical fertilizers, soil compaction, water quality decline, agricultural products are seriously polluted, and the entire farmland ecological environment and people's living environment are affected. How to maintain the sustainable development of my country's agriculture has attracted great attention from governments at all levels. Especially after my country's accession to the WTO, my country's agriculture has been severely challenged. To develop export-earning agriculture, we must vigorously promote the development of green food and pollution-free food. Moreover, under the impact of the international financial crisis, the traditional chemical fertilizer industry is in deep trou...
