Nitrogen-fixing phosphate-dissolving potassium-dissolving microorganism compound fertilizer and preparation method thereof

Abstract

The invention discloses a nitrogen-fixing phosphate-dissolving potassium-dissolving microorganism compound fertilizer which comprises the following raw materials in parts by weight: 60-80 parts of mixed bacteria solution, 15-20 parts of filling materials, 25-35 parts of urea, 15-20 parts of calcium magnesium phosphate fertilizer, 20-30 parts of potassium sulphate, 3-5 parts of sodium silicate, 0.1-0.3 part of copper sulfate, 0.2-0.4 part of potassium borate, 0.1-0.3 part of manganese sulfate, 0.2-0.3 part of zinc chloride, 0.2-0.4 part of ferric sulfate, 0.5-1.5 parts of calcium chloride, 2-4 parts of sodium alginate, 5-15 parts of malt oligosaccharide, 5-10 parts of saccharified residue, 10-20 parts of amino acids and humic acids, 5-10 parts of bean pulps and 5-8 parts of honey. The invention also discloses a preparation method for the nitrogen-fixing phosphate-dissolving potassium-dissolving microorganism compound fertilizer. The nitrogen-fixing phosphate-dissolving potassium-dissolving microorganism compound fertilizer can fix nitrogen and dissolve phosphate and potassium, can be used for improving soil, is capable of firmly absorbing biological bacterium and is capable of buffering the influence of new environment on the biological bacterium.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nitrogen-fixing, phosphorus-, potassium-, and potassium-decomposing microbial compound fertilizer and a preparation method thereof. Background technique [0002] Microbial fertilizer is a product in which the life activities of microorganisms cause crops to obtain specific fertilizer effects, and it is a type of fertilizer used in agricultural production. Immobilized cell technology is a technology in which biological cells with certain physiological functions, such as microbial cells, plant cells or animal cells, are fixed in a certain way and used as solid biocatalysts. At present, the methods of immobilizing cells mainly include embedding method and adsorption method. [0003] The embedding method uses physical methods to wrap the cells in the network structure of the gel to achieve the immobilization of the cells. The embedding method has the advantages of high biolog...

Problems solved by technology

This method is simple to operate, and only needs to put the carrier in the fermentation broth to stir and mix evenly. The advantage is that the reaction conditions are mild and has no toxic effect on the cells. The disadvantage is that the combination is not firm, the cells are easy to fall off, and it is greatly affected by environmental changes. limit its application
