Abstract
The invention discloses an acid soil conditioner, which is made from the following raw materials, by weight part, 9-11 of plant ash, 2.6-2.8 of apatite powder, 10-12 of golden needle mushroom residue, 5-6 of pod powder, 30-34 of bagasse, 1.6-1.8 of magnesium sulfate, 4-5 of potassium nitrate, 3-4 of lime powder, 65-70 of polluted pig dung and urine, 12-15 of a black liquor from papermaking, 3.6-3.8 of a nitric acid solution with the concentration being 10%, 11-13 of a thick alum liquid and a proper amount of water. In the soil conditioner, alkaline raw materials, such as plant ash, are adopted and match thoroughly-decomposed materials including processed pig dung and urine and bagasse, and therefore salt in the soil can be well neutralized. Alkaline-earth metal, such as magnesium sulfate, is added and matches golden needle mushroom residue for prompting activity of rhizosphere microorganisms, prompting insoluble mineral elements in the soil to change into soluble nutrients, and preventing manganese and aluminum damage to the soil. The available phosphorus content is the soil is further increased, and the obstacle of phosphorus deficiency is overcome under the function of application of apatite powder, and the problem that acid soil is low in planting yield is solved.
Description
Technical field
The present invention relates to technical field of soil remediation, particularly relate to a kind of acid soil improving 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 acid soil improving agent.
The present invention is achieved by the following technical solutions:
A kind of acid soil improving agent, is prepared by the raw materials in: plant ash 9-11, floats 2.6-2.8, needle mushroom dreg 10-12, soybean pod shell powder 5-6, bagasse 30-34, magnesium sulfate 1.6-1.8, potassium nitrate 4-5, pulverized limestone 3-4, pollution Pig dung and urine 65-70, black liquid 12-15,10% salpeter solution 3.6-3.8, Alumen slurry 11-13, water are appropriate.
Specifically comprising the following steps that of described acid soil improving agent preparation method
(1) needle mushroom dreg, plant ash, soybean pod shell powder, bagasse are mixed and added into the water of gross weight 1.5-2 times, and 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 450-470 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 40kHz, compound is pressed after ultrasonic 90-100 minute 60-80 rev/min and stirs 3 hours, stand 70-90 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, magnesium sulfate, floats mixing granulation, spheroidal particle is obtained standby；
(4) Alumen starch comminution is crossed the most afterwards 100-120 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 110-120 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, potassium nitrate, pulverized limestone 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 conditioner of the present invention uses the materials that become thoroughly decomposed such as the Pig dung and urine after the basic materials cooperation process such as plant ash, bagasse, can the preferable alkali in sweetening of the soil, the interpolation of the alkaline-earth metal such as magnesium sulfate coordinates needle mushroom dreg to promote, and rhizosphere microorganism is movable, slightly solubility mineral element in soil is promoted to become the nutriment of solubility, release Manganese In Soils, aluminium toxicity, and increase available phosphorus content in soil further, under joining the effect executing floats, alleviate the phosphorus deficiency obstacle of soil, solve the problem under acid ground plantation yields poorly.
