Abstract
The invention relates to the improvement and fertility betterment of farmland soil, particularly disclosing a fertility-betterment type soil-conditioner and the preparation method thereof. The soil conditioner is made by the following raw material of different weights: 50 to 55 portions of alkaline residue, 32 to 35 portions of peat, 12 to 14 portions of light-burned dolomite and 3 to 4 portions of ammonium bicarbonate. The preparation method is that the alkaline residue, the peat and the ammonium bicarbonate are mixed by the above weight proportion and stirred and accumulated for 5 to 7 days. Then the light-burned dolomite with the above weight proportion is added. At last, the soil conditioner is grinded and bagged. The soil conditioner of the invention has the advantages of good exterior, stable physicochemical characters, no moisture absorption and non-lumping, which can be widely used for improvement and fertility betterment of the southern acid soil and supplies balanced calcium, magnesium, and other nutrients for the crops.
Description
Technical field
The invention belongs to agrotechnique, the improvement that relates to arable soil with foster and apply fertilizer, be specifically related to a kind of fertility-betterment type soil-conditioner and preparation method thereof.
Background technology
Ammonia alkali process is made the alkaline residue that soda ash produces, and is a kind of trade waste.Main component is CaCO
3And Ca (OH)
2, and contain a certain amount of Mg (OH)
2With a spot of trace element in other, alkalescence, the product after the processing treatment can be improved acid soil and crop calcium magnesium nutrition is provided.Because the alkaline residue calcic enriches, it is less to contain magnesium, and CaCO
3Account for leadingly, there is phenomenon such as improve the soil that effect is stable inadequately, calcium magnesium activity and equilibrium supply thereof are relatively poor in the product after the processing in agricultural process.In addition, the physical behavior of alkaline residue is very poor, and particularly dried alkaline residue quality is hard, and it is agricultural to have a strong impact on its resource utilization, so the modification of alkaline residue and loose metallization processes also need to be resolved hurrily.
Peat is rich in organic matter and humic acids, and its processed products have to improve the soil fosters and apply fertilizer, increases the effect of crop alimentary, stimulating plant growth.It is acid that China's peat generally is, and is subjected to certain limitation in the application of southern acid soil.
The product of alkaline residue and peat hybrid process can overcome some drawbacks that the two is handled alone, such as: by the complexing action of humic acids and calcium magnesium, can put forward the activity of high contents of calcium and magnesium nutrient; By neutralization of acid with base, can reduce peat acidity.But also bring some problems: one is owing to dilution effect, and the Mg content of product is lower; It is two because neutralizing effect, and the alkalescence of product reduces, and influence is to the acid soil improvement effect.
Therefore, with main raw materials such as alkaline residue, peat, manufacturing can improve acid soil and crop calcium magnesium nutrition, the fertility-betterment type soil-conditioner that can increase fertility of land again are provided, and solves the problem that exists in complete processing and the recipe ingredient, the target that the person that always is the soil-working explores.
Summary of the invention
At the product that with alkaline residue, peat etc. is main raw material processing, have that visual appearance is poor, the Mg content deficiency, alkalescence is on the low side, influences the present situation of application effect.It is good that primary and foremost purpose of the present invention provides a kind of physicochemical character, can improve acid soil, culture fertility, soil conditioner (or ca and mg fertilizer) that again can balance crop calcium magnesium nutrition.
Another object of the present invention provides the preparation method of above-mentioned soil conditioner.
Purpose of the present invention realizes by following technical scheme:
A kind of fertility-betterment type soil-conditioner is obtained by the feedstock production of following weight part: 50～55 parts of alkaline residues, 32～35 parts in peat, 3～4 parts of 12～14 parts of light dolomites and carbon ammoniums (bicarbonate of ammonia);
In the described alkaline residue, moisture content≤30%, calcium contents 〉=27%, Mg content 〉=3%;
In the described peat, moisture content≤5%, humic acids content 〉=40%;
In the described light dolomite, calcium contents 〉=40%, Mg content 〉=24%;
In the described carbon ammonium, moisture content≤3%;
Above-mentioned percentage ratio is mass percent, and wherein the mass percent of calcium, magnesium and humic acids is in butt.
For reaching better effect, in the soil conditioner of the present invention, control following technical parameter: moisture≤8%, calcium (Ca) 〉=18%, magnesium (Mg) 〉=5%, humic acids (HA) 〉=18%, pH value 8～11, the outward appearance grey black, particle diameter≤1.0mm,
Above-mentioned percentage ratio is mass percent, and wherein the mass percent of calcium, magnesium and humic acids is in butt.
The present invention also provides the preparation method of above-mentioned soil conditioner, comprises the steps:
Piled up 5～7 days after earlier alkaline residue, peat and carbon ammonium being stirred by described weight proportion; The light dolomite that adds described weight proportion afterwards; Pulverize at last, pack.
Preferably, aforesaid method may further comprise the steps:
A, peat and carbon ammonium get mixture (1) by described weight proportion stirring and evenly mixing;
The alkaline residue of b, described weight proportion and mixture (1) mix once again; Get mixture (2);
C, mixture (2) are piled up and were placed 5～7 days, get mixture (3);
D, mixture (3) drying get mixture (4);
E, mixture (4) add the light dolomite of described weight proportion, get mixture (5);
F, mixture (5) get finished product through pulverizing after the pack.
Groundwork principle of the present invention: piled up 5～7 days alkaline residue, peat and the carbon ammonium back that stirs in proportion, and the carbon ammonium decomposes the gas that produces alkaline residue is played expanded, loose and modifying function in this process at alkaline environment, just as steamed sweet bun with sodium bicarbonate; Peat can absorb the alkaline residue redundant moisture, can also decompose the ammonia of overflowing by the fixed carbon ammonium, forms water miscible ammonium humate, i.e. the ammonification of humic acids; Humic acid and the complexing of calcium magnesium have activated calcium magnesium nutrient simultaneously.Material moisture after the accumulation is higher, needs dry.Add light dolomite afterwards, regulate the alkalescence and the Mg content of mixture, pulverize (levigate), pack at last.The soil conditioner product is generally thin more long-pending big more with soil contact, and its effect of improving the soil is good more.The pulverizing process of step f can obtain particle diameter 40～60 purpose powder as using ball mill.
Compare existing soil conditioner, the present invention has following beneficial effect:
Soil conditioner of the present invention, visual appearance is good, physicochemical character is stable, non-hygroscopic, do not lump.Can be widely used in the improvement of southern acid soil and foster and apply fertilizer, for farm crop provide isostatic calcium magnesium nutrition and other nutrients.Long-term application can progressively improve soil pH value, increases the soil organism and humic acids content, builds the well environment on the spot that is suitable for root growth, improves nutritional status and the resistance of plant, and the crop yield quality is improved.
