Technology for functional fertilizer-saving synergistic fertilizers made of polysaccharide biological colloid of straw

Abstract

The invention discloses a technology for functional fertilizer-saving synergistic fertilizers made of polysaccharide biological colloid of straw. The technology includes extracting the polysaccharidebiological colloid from a raw material by the aid of enzymatic hydrolysis processes; treating extracted residues of the raw material by the aid of microbial fermentation processes to obtain microbialorganic matters; adding trace elements and fertilizers required in plant growth procedures into the microbial organic matters to obtain mixtures; adding the extracted polysaccharide biological colloidinto the mixtures in low-temperature granulation procedures to prepare products which are the functional fertilizer-saving synergistic fertilizers made of the polysaccharide biological colloid of thestraw. The raw material is the waste straw of crops. The technology has the advantages that growth and trace element absorption of the root systems of crops can be promoted by the functional fertilizer-saving synergistic fertilizers prepared by the aid of the technology, and fertilizer-saving synergistic effects further can be realized; the potential of hydrogen of soil can be regulated by the functional fertilizer-saving synergistic fertilizers, trace elements can be supplemented in the soil, and the stress resistance of the crops can be improved.

Description

technical field [0001] The invention relates to the technical field of crop fertilizers, and more specifically relates to a straw polysaccharide biocolloid functional slimming and synergistic fertilizer technology. Background technique [0002] Fertilizer is an important means of production in agriculture and plays an irreplaceable role in ensuring food security, but at the same time, fertilizer is also a strategic material with high energy consumption and resource shortage. At present, the fertilizer loss rate is high and the economic loss is huge. The fertilization period of fertilizer is short, it is difficult to meet the characteristics of fertilizer demand throughout the growth period of crops, and the loss rate of fertilizer is high, and a large amount of fertilization will also cause serious environmental pollution. [0003] Therefore, how to improve the utilization rate of fertilizers is an urgent problem to be solved by those skilled in the art. Contents of the i...
