Problems solved by technology

[0003] The salt tolerance of functional microorganisms is limited. How to give full play to the role of such functional microorganisms in soil has always been a concern of bio-fertilizer researchers. It is a common method to use fertilizer additives to isolate functional microorganisms from inorganic nutrients. The method of layered coating, but the effective living bacteria of functional microorganisms are easily affected by moisture, pH and storage environment, etc.

preparation example Construction

[0032] The preparation method of block biological water-soluble fertilizer:

[0033] Step 1, preparation of compound microbial agent, select Bacillus amyloliquefaciens, Bacillus licheniformis, Bacillus subtilis to inoculate into liquid biochemical potassium fulvic acid for fermentation, and obtain compound microbial bacteria with effective viable bacteria amount ≥ 2 billion / ml According to the mass concentration ratio of 1:6, the compound microbial bacterial powder is obtained by spray drying, the effective amount of viable bacteria is ≥100 billion / g (300 mesh), and it is mixed with ten polyglycerol monomyristate according to the mass ratio Mix 1:3 and set aside.

[0034] Step 2, formula formulation, using the filtered slag-removing liquid biochemical potassium fulvic acid solution, weighed and crushed and sieved ammonium nitrate, potassium nitrate, monoammonium phosphate, potassium dihydrogen phosphate, potassium sulfate, full hydrotrope, compound Microbial agent, mineral so...

Embodiment 1

[0046]100 parts of liquid biochemical potassium fulvic acid, 15 parts of mineral source potassium fulvic acid, 500 parts of ammonium nitrate, 200 parts of potassium nitrate, 5 parts of hydrotrope, 5 parts of compound microbial agent, 185 parts of monoammonium phosphate.

Embodiment 2

[0048] 150 parts of liquid biochemical potassium fulvic acid, 500 parts of ammonium nitrate, 10 parts of mineral source potassium fulvic acid, 125 parts of potassium dihydrogen phosphate, 300 parts of potassium nitrate, 5 parts of hydrotrope, 5 parts of compound functional microbial powder.

Abstract

A blocky biological water-soluble fertilizer disclosed in the invention is prepared from, by weight, 100 to 150 parts of liquid biochemical potassium fulvate, 5 to 15 parts of mineral source potassium fulvate, 250 to 500 parts of ammonium nitrate, 200 to 300 parts of potassium nitrate, 5 parts of a water-soluble auxiliary agent, 5 parts of a compound microbial agent and any one of 100 to 250 parts of monoammonium phosphate, 100 to 150 parts of monopotassium phosphate and 100 to 200 parts of potassium sulfate. The water-soluble fertilizer has the beneficial effects that 1, compared with conventional liquid, powder and granular organic water-soluble fertilizers, the blocky biological-organic-inorganic water-soluble fertilizer has the characteristics of being easy to package, transport and store, and does not cause the increase of manual management and protection cost due to leakage; 2, functional microorganisms in the fertilizer are bacillus which is high in salt tolerance and has the functions of rooting, promoting growth, dissolving phosphorus, dissolving potassium and resisting soil-borne diseases;.

Description

technical field [0001] The invention relates to the field of biological fertilizers, in particular to a block-shaped biological water-soluble fertilizer and a preparation method thereof. Background technique [0002] With the vigorous promotion and implementation of water-fertilizer integration technology, water-soluble fertilizers containing a large number of elements, water-soluble fertilizers containing amino acids, and water-soluble fertilizers containing humic acid have been more and more applied to the agricultural production process. The large-scale application of water-soluble fertilizers has greatly improved The efficiency of agricultural production has further strengthened the efficient use of water and fertilizer resources and greatly improved the quality of crop production. However, with the increase of planting density and stubble number, inorganic nutrients will inevitably remain and accumulate in the soil, resulting in excessively high concentration of soil sol...
