Water 11.
The preparation method of green organic humic acid Si-K fertilizer of the present invention, comprises the following steps:
1) activation treatment is carried out to rice hull ash and plant ash
Homogeneous phase mixing is carried out by former to rice hull ash, plant ash and humic acids powder by ratio of weight and the number of copies 3.5: 3.5: 3 ratios input Horizontal Heating dry-blender, add 85 degrees Celsius of hot water, hot water and mixture ratio of weight and number are: 9: 10, be stirred to thick, warming while stirring to 100 degree Celsius, the static insulation of constant temperature 1 hour;
2) properties-correcting agent is prepared
By in diatomite, citric acid, water by ratio of weight and the number of copies 1: 0.02: 2 ratio input reacting by heating still, heating makes temperature rise to 100 degrees Celsius, and constant temperature keeps 30 minutes, and cooling is rear and obtain acid modification agent;
3) modification
By step 2) the acid modification agent prepared puts into step 1) in the material that mixes, acid modification agent and the weight of material portion rate mixed are 3: 10, mix stirring 30 minutes;
4) drying and processing
By step 3) the material transfer roller of modification is delivered in dryer and dries, and just dry after terminating, material moisture controls be less than 35%;
5) granulation
To step 4) material of just drying carries out granulation.
6) again dry
To step 5) particle made dries further, and dry after terminating, the water content of particle is less than 15%;
7) pack
To step 6) particle of having dried packs.
By such scheme, the present invention at least has the following advantages: utilize the subacidity of humic acid to neutralize the slight alkalinity of rice hull ash, plant ash, adds the activity of effective silicon-dioxide in rice hull ash, plant ash, effectively potassium; Meanwhile humic acid have also been obtained activation treatment, and final generation humate material, further increases fertilizer quality.The fertilizer obtained can be used separately, also can mix with other chemical fertilizer and use, improve fertilizer.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technique means of the present invention, and can be implemented according to the content of specification sheets, be described in detail as follows below with preferred embodiment of the present invention.

To step 4) material of just drying carries out granulation.
6) again dry
To step 5) particle made dries further, and dry after terminating, the water content of particle is less than 15%;
7) pack
To step 6) particle of having dried packs.
Working process of the present invention is as follows:
In rice hull ash, the main composition utilized is silicon-dioxide, and it is organic composition, and content is generally between 45%-70%, active in about 50%, in plant ash, the main composition utilized is potassium, and it is organic composition, content is generally about 5%., the pH value of above two kinds of materials is generally at 10-11, meta-alkalescence, there is a large amount of free alkalis, be applied directly in farmland, on the one hand due to its aobvious alkalescence, the harm of burning seedling can be produced, on the other hand without activation modification process, silicon-dioxide, the nutrients such as salt of wormwood are fixed in semicoke, nutrient can not discharge, also crop is made to be difficult to absorb silicon-dioxide wherein and potassium, moreover, mix with other chemical fertilizer and use, due to its aobvious alkalescence, the fertilizer efficiency of other chemical fertilizer is caused to decline on the one hand, on the other hand it and other chemical fertilizer react with, produce obnoxious flavour, cause production, storage and the hidden danger in transporting.
For the shortcoming of above two kinds of materials, select resourceful naturally weathered product of coal, i.e. the former powder of humic acid, as activator; The former powder content of humic acid of humic acid is at 50%-70%, pH value is about 5, slant acidity, main operational principle is: by rice hull ash, plant ash, the former powder of humic acid according to ratio of weight and number being: 3.5: 3.5: 3 carry out Homogeneous phase mixing after, add 85 degree of hot water, hot water and weight of material portion rate are 9: 10, warming while stirring to 100 degree Celsius, constant temperature is incubated 1 hour, after heating chelatropic reaction, reach the slight alkalinity with rice hull ash, plant ash in utilizing the subacidity of humic acid to go, significantly reduce the content of free alkali; In addition, utilize the slight alkalinity of rice hull ash, plant ash simultaneously, by chelatropic reaction of heating, make humic acid obtain activation treatment, namely generate humate material, obtain the high-quality humic acid fertilizer that crop needs; After activation treatment, silicon dioxide activity increases about 20%, and alkalescence reduces greatly, and pH value is about 8.5.
In order to reduce the pH value of material further, it is made to use separately, also can mix with chemical fertilizer and use, the agent of configuration acid modification, diatomite, citric acid (powdery, content 98%), water are carried out Hybrid Heating according to the ratio of weight and number of 1: 0.02: 2, is heated to 100 degree, is incubated 30 minutes, obtained acid modification agent, pH value controls between 3-4.Then acid modification agent and mixture are carried out Homogeneous phase mixing according to the ratio that ratio of weight and number is 3: 10, finally make the pH value of mixture control between 6-8.
By the humic acid Si-K fertilizer that above technique is obtained, effective dioxide-containing silica is greater than 20%, and content of humic acid is greater than 30%, and potassium content is greater than 5%, and organic matter reaches more than 25%.It is a kind of green pure organic fertilizer, has the advantage of humic acid fertilizer and organic silicon fertilizer, can improve soil aggregate by using, and increases utilization rate of fertilizer, fertilizer conservation water conservation, reduces disease and pest, improves output, strengthens quality.
The above is only the preferred embodiment of the present invention; be not limited to the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
