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;.

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 liquid was heated to 80 ℃, heated and dissolved according to the order of ammonium nitrate, monopotassium phosphate, potassium nitrate, monoammonium phosphate, potassium sulfate and potassium fulvic mineral source, after hydrotropes, material input is completed, stirring was charged into a stainless steel mold was cooled to room temperature (25 ° C).

[0035] Step three, the preparation of the finished product, the second cooling step of the finished composite module is added to the microbial agents, can be shaped after the natural wrapped in uniform.

[0036] Step four, packaging, vacuum packaging machine using a three step cooling the finished individually vacuum packed.

[0037] A step of the process parameters in the spray drying composite microorganism sinensis follows: LPG- using non-standard high-speed centrifugal spray drier type 200, inlet air temperature 150 ℃, the feed frequency of 11Hz, solid material content of 10%, the air intake negative pressure pressure 10Pa, negative wind pressure 25Pa, inlet air temperature 150 ℃, the wind pressure of the negative pressure 25pa, atomizing frequency 300Hz.

[0038] Functional powder is formed by spray-drying after particle size of 100 mesh, using a jet mill to regrind the material 300 mesh.

[0039] Water-soluble inorganic raw materials hit the front two crushing step is screened: pulverized through a ball mill through a 40 mesh sieve, hydrotropes sodium dodecyl sulfate and powdered potassium fulvic mass ratio 2: 3 preparation.

[0040] Step two in the mold according to the laws of crop fertilizer sales demand and highly customizable.

[0041] In step a hydrotrope decaglyceryl myristate (Q-14s) a non-ionic surfactant, a hydrophilic emulsifier is the case, to ensure effective mucoid bacteria powder adhering surface of the fertilizer, while ensuring the good dispersion properties in water; sodium dodecyl sulfate as a dispersant and a wetting agent can improve the rate of dissolution of the bulk fertilizer and user experience of the application process.

[0042] The main role of potassium fulvic ore source material is adjusted to neutral pH, while promoting the growth of crops, improve fertilizer use efficiency, enhance crop resistance.

[0043] Finished moisture content (percent by mass) between 3% -6%, pH 6.8-7.2.

Example Embodiment
