Example Embodiment

[0030] Example

[0031] Using potassium (K) in Zheng'an County, Guizhou Province 2O) 9.77% potassium shale, take 96% potassium shale by weight and 4% bone by weight, mix and pulverize to prepare 80 mesh potassium fermented potassium base powder.

[0032] Then add 25% by weight of auxiliaries with 50% by weight of enzyme substrate, then add 15% by weight of coal waste, 10% by weight of organic humic acid from tung shells, and mix, pulverize and stir evenly to prepare enzymatic fermentation. agent.

[0033] Take 75% by weight of fermented potassium base powder and 25% by weight of enzymatic starter, mix and pulverize, add water, stir evenly, stack and ferment, and heat up from 17°C to 65°C at room temperature, continue stacking for 25 days, and then cool down for 20 days. Cooled to room temperature 17 ℃, that is, to prepare fermented potash fertilizer.

[0034] The fermented potash fertilizer of the above-mentioned preparation, through detection and analysis, it contains: K ...

Abstract

The invention provides a method for producing fermented potash fertilizer by bacterium enzymatic treatment of potassium-containing rock and preparing organic-inorganic compound mixed fertilizers, which consists of mixing 80-97% of potassium-containing rock and 3-20% of bones, disintegrating into fermented potassium base material, then mixing 20-50% of zymase base material, 20-50% of auxiliary agent, 20-50% of organic matter, disintegrating into enzymatic leaven, the mixing 50-80% of fermented potassium base material powder, 10-50% of enzymatic leaven, disintegrating and depositing 20-40 days for fermentation, elevating the temperature from normal temperature 14-18 deg. C to 88 deg C, cooling down to 14-18 deg. C, thus preparing potassium fertilizer ,which compresses 50-80% of fermented potassium fertilizer, 4-20% of urea, 5-20% of heavy calcium, 10-30% of organic matter.

Description

technical field [0001] The invention belongs to the technical field of biochemical fertilizers, and in particular relates to a method for producing fermented potassium fertilizers and preparing organic-inorganic compound fertilizers by enzymatically converting potassium-containing rocks with bacteria. Background technique [0002] Potassium-containing rocks such as potassium-feldspar, potassium-containing shale, illite, and mung bean rock that are naturally stored in nature are mineralized potassium, which is difficult to decompose, difficult to dissolve in water, and difficult for plants to absorb. These refractory potash resources are extremely rich, but difficult to be developed and utilized. If industrial methods such as sulfuric acid method and hydrochloric acid method are used to develop and utilize refractory potassium ore, the equipment is easy to corrode, the process is more complicated, the separation rate is low, and the cost is high. Using the sintering method, ...
