Problems solved by technology

In the prior art, although there are studies on the mixing of formaldehyde and biochar as a mixed fertilizer, the physical and chemical properties of biochar are affected by the raw materials and the pyrolysis process, and there are great differences in the physical structure and chemical properties of biochar with different raw materials. How to find out how to improve the soil quality of various soils and meet the nutritional needs of various crops is the focus of current research
In addition, the urea-formaldehyde reaction has problems such as complex reaction, high cost, and excessive cross-linking reaction. How to skillfully combine the urea-formaldehyde reaction and biomass charcoal to prepare long-acting compound fertilizers is also an urgent problem to be solved.

Abstract

The invention provides charcoal-based bioorganic compound fertilizer and a preparation method thereof. The charcoal-based bioorganic compound fertilizer is obtained by adopting an actinidia-chinensispruned branch, timber offcut, imperata cylindrica, pennisetum alopecuroides and a traditional Chinese medicinal decoction dreg, carbonizing, then mixing with fermented plant powder, monoammonium phosphate, potassium chloride, indolebutyric acid, thiourea, triacontanol, zinc chloride and camsellite, using phosphoric acid and niobium pentaoxide as catalysts and diisopropyl peroxydicarbonate as an initiator, spraying a urea formaldehyde reaction solution, granulating and drying. The preparation method has the advantages of simple and easy-to-operate preparation steps, good economical efficiency and high in conversion ratio of a condensation reaction and the prepared charcoal-based bioorganic compound fertilizer can meet the demands of various kinds of soil and various crops.

Description

Technical field [0001] The invention belongs to the technical field of fertilizers, and specifically relates to a carbon-based biological organic compound fertilizer and a preparation method thereof. Background technique [0002] In recent years, biomass charcoal has become the focus of attention in the research fields of agriculture, forestry, environment and energy. Biomass charcoal is the product of carbonizing plants through pyrolysis in a low-oxygen or anaerobic environment. With the rapid development of my country's traditional Chinese medicine industry, there is an increasing number of waste medicine residues from traditional Chinese medicine. According to preliminary statistics, millions of tons of waste medicine residue are generated every year during the industrial production of traditional Chinese medicine pharmaceuticals. The use of landfilling, incineration, and storage in fixed areas will cause serious pollution to the surrounding water quality, soil and air, affect...
