Biochar-based fertilizer with nutritional and improvement functions

Abstract

The invention belongs to the field of agricultural production, and particularly discloses a charcoal-based fertilizer with nutritional and improvement functions. The charcoal-based fertilizer comprises a biochar mixture, an organic fertilizer fermentation mixture, an additional mixture and auxiliary materials, wherein the biochar mixture comprises plant straw, seed shells, sawdust, sludge biochar and lignite biochar; the organic fertilizer fermentation mixture comprises bone meal, biogas residues, an excrement mixture, mushroom sticks, oil cakes and fermentation strains; the additional mixture comprises furrow soil, a microbial functional agent, humus soil, red soil, polymethyl methacrylate and cadmium chloride; and the auxiliary materials comprise bentonite, glycerol, cane sugar, rosin and an additive. According to the invention, waste materials are fully utilized, functional bacteria and organic matters in the organic fertilizer can be fully released, soil can be improved, release of nutrients fixed by the soil can be promoted, a nutrient content is high, soil organic matters and beneficial microbial florae can be increased, and basic nutrients needed by crop growth can be provided.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a biochar-based fertilizer with nutrition and improvement functions. Background technique [0002] With the increasing development of society, especially the rapid development of animal husbandry and agriculture, a large amount of agricultural and forestry wastes such as straw and human and animal manure are produced every year in my country. These wastes have caused a series of environmental problems in the process of treatment or disposal, such as air pollution problems caused by burning straw, odor and water pollution problems caused by the discharge of human and animal manure. It is worth noting that both straw and human and animal manure are rich in organic matter, and human and animal manure is also rich in nitrogen and phosphorus, which can be used to improve soil nutrients. However, the current agricultural production is overly dependent on chemical fertilizers. Th...

Problems solved by technology

However, the current agricultural production relies too much on chemical fertilizers. Not only can these excessive chemical fertilizers not be effectively absorbed and utilized, but a considerable part of them enters the water body and causes eutrophication of the water body. Excessive application of chemical fertilizers can easily lead to soil compaction , soil acidification, nutrient loss, and the decline in the quality of agricultural products. The high yields brought about by the extensive use of chemical fertilizers and pesticides and intensive farming have concealed the rapid degradation of soil quality.
