Description

A kind of increasing potassium soil-repairing agent

Technical field

The present invention relates to technical field of soil remediation, particularly relate to a kind of increasing potassium soil-repairing agent.

Background technology

Soil improvement is the bad quality for soil and structure, takes corresponding measure to improve soil property, increases soil fertility, and soil improvement renovation agent is a kind of important application of soil improvement.But seen soil remediation modifying agent has many defects in the market: one is to use raw material with synthetic macromolecular compound, and it is not easily decomposed and extended residual in soil, has potential safety hazard；Two is function singleness, for variety classes soil, such as acid and basic soil, heavy metal pollution degree, nutrient are deficient etc. without effectively for, cause improveing remediation efficiency low, even play retroaction；Three is that the cycle of improving the soil is long, and relatively costly, it is impossible to large-scale application.For problem above, low cost, high specific aim and environmentally friendly soil remediation modifying agent become soil improvement aspect prior development direction.

Pig dung and urine is as a kind of renewable biological source wide, with low cost of originating, the nutrients such as abundant organic matter and N P and K are contained because of it, use as the raw material of soil improvement reparation and there is great potential, and owing to economization cultivation needs, during pig is fed, feedstuff contains a large amount of additive, cause heavy metals exceeding standard, indirect pollution Excreta.And by pickling and ultrasonication, the metallic compound of indissoluble state in Pig dung and urine can be made to form soluble metal ion, and utilize acoustic cavitation effect to make the pulverizing of pig manure granule, cell wall crack, the heavy metal release of order absorption and parcel is out, the two is used in combination and reaches to purify purpose, makes this cheap raw material of pollution Pig dung and urine apply and is possibly realized in the preparation of soil improvement renovation agent.

Alumen slurry is Alumina by-product when " water seaoning " produces Alumen, through dried gained white powdery solids, its main component is silicon oxide, aluminium oxide and the silicate mineral of water composition, and containing macroelement and various trace elements such as abundant Ca, Mg, Fe, K, S, P, because it has the features such as granule is thin, specific surface area is big, absorption affinity is strong, there is in terms of soil improvement good application prospect.

The above being conjointly employed in the exploitation of soil remediation modifying agent, is simply easily achieved, the development for soil improvement renovation agent opens new way.

Summary of the invention

The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of increasing potassium soil-repairing agent.

The present invention is achieved by the following technical solutions:

A kind of increasing potassium soil-repairing agent, is prepared by the raw materials in: coffee grounds 22-24, waterweed 8-10, sodium phosphate 2-3, poly-aspartate 2.3-2.5, alcohol waste mash 6-7, Folium Bambosae flavone powder 1.5-1.8, Nicotiana tabacum L. combustion ash 15-18, carnallite fine powder 3-4, pollution Pig dung and urine 59-61, black liquid 12-14,10% salpeter solution 3.5-3.6, Alumen slurry 9-10, water are appropriate.

Described increases specifically comprising the following steps that of potassium soil-repairing agent preparation method

(1) coffee grounds, waterweed, Nicotiana tabacum L. being fired water grey, that alcohol waste mash is mixed and added into gross weight 1.5-2 times, after mixing, in retting fermentation 3-4 week, obtain fermentation residue and fermentation liquid be standby after fermentation material crushes expression separation；

(2) put into after black liquid being dried in calcining furnace, calcine 80-90 minute at 450-460 DEG C, it is mixed and added into gross weight 3-4 times quality water with pollution Pig dung and urine after taking-up, 10% salpeter solution is added after stirring evenly, and compound is carried out supersound process, supersonic frequency is 45kHz, compound is pressed after ultrasonic 90-100 minute 60-80 rev/min and stirs 3 hours, stand 60-90 minute afterwards, after removing upper solution, lower floor's drying materials is pulverized stand-by；

(3) by step 1 gained fermentation residue and step 2 gained material, carnallite fine powder, Folium Bambosae flavone powder mixing granulation, spheroidal particle is obtained standby；

(4) Alumen starch comminution is crossed the most afterwards 80-100 mesh sieve, and mix homogeneously by solid-liquid mass ratio 1:4 with 1mol/L sodium hydroxide solution, be again heated to 75-80 DEG C, filter after being incubated 85-95 minute and take out Alumen slurry, clean to neutral with water, dry for standby；

(5) step 1 gained fermentation liquid is mixed with step 4 gained modification Alumen slurry, sodium phosphate, poly-aspartate and other residual componentss, again step 3 gained granule is placed in the roller machine with shower nozzle of the top, during rolling granule, granule is uniformly sprayed by mixed fermentation liquid through shower nozzle, the coated particle oven drying at low temperature at 40-45 DEG C that finally will obtain.

The using method of the present invention is for being embedded at upper soll layer 10-15cm by renovation agent after being turned over by contaminated soil, and every mu of soil uses 80-100kg renovation agent.

The invention have the advantage that

The mixing scrubbing of Pig dung and urine and black liquid uses and soil organic level is greatly improved, and erodable Alumen slurry surface after thermokalite modification Alumen slurry, it is made to become rough porous, surface texture loosens, and specific surface area improves, and strengthens the lattice fixation of its heavy metal ion, serve not only as improvement reparation grain skeleton and there is good stability, and the residuals such as heavy metal-passivated, chemical medicine can be adsorbed, alkaline modification Alumen slurry mixes with the Pig dung and urine of acidifying, also ensure that stablizing of P in soil H-number.The soil-repairing agent of the present invention is for the problem of current China soil universal potassium deficiency element, addition by rich potassium raw materials such as Nicotiana tabacum L. combustion ash, carnallite fine powders, the common effect of the collaborative many nutrients of the decomposed organic matter such as coffee grounds, waterweed, improve the maximum absorption of element, and it is aided with Folium Bambosae flavone powder, poly-aspartate promotion soil layer enzyme work, realize release and the accumulation of effective potassium element in soil, and then the plantation for crop provides advantage.
