Example Embodiment
[0032] Preparation of water-soluble bulk biological fertilizer:
[0033] Step a, preparation of the composite microbial agents, select Bacillus amyloliquefaciens, Bacillus licheniformis, Bacillus subtilis inoculated into liquid potassium fulvic ferments prepared ≥20 effective amount of one hundred million viable cells / ml composite microbial agents, at a mass concentration ratio of 1: 6, by spray drying complex microbial sinensis, an effective amount of viable ≥1000 one hundred million / g (300 mesh), which with decaglyceryl myristate mass ratio 1: 3 mix standby.
[0034] Step two, to develop formulations, liquid slag by filtration biochemical potassium rot yellow solution, weighed according to the composition sieving pulverized ammonium nitrate, potassium nitrate, monoammonium phosphate, potassium dihydrogen phosphate, potassium sulfate, hydrotropes full, complex microbial agents, potassium fulvic mineral source, biochemical yellow liquid rot potassium solution, potassium fulvic...

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...
