The conditioner consists of attapulgite, phosphogypsum, a weathered coal-sodium polyacrylate complex and bentonite; the conditioner is characterized in that the conditioner is prepared by uniformly mixing the following materials in parts by weight: 5-7 parts of attapulgite, 1-2 parts of phosphogypsum, 1-3 parts of weathered coal-sodium polyacrylate complex and 1-2 parts of bentonite; the attapulgite, the sodium polyacrylate and other materials are modified, grafted and polymerized; the conditioner has functions of retaining water and fertilizer, reducing salinity, decreasing alkali, loosening soil and the like, so as to improve the soil in a corn field, reduce the degree of salinization damage and save water; the conditioner, added to a fertilizer, can produce improved fertilizer; and compared with an existing method, the method has the advantages of being low in cost, rich in raw material, efficient and the like.
Description
Technical field
What the present invention relates to is a kind of modifying agent improving corn soil, area, saltings soil function.
Background technology
In northern China, weather is comparatively dry, and steam output is greater than quantity of precipitation; the salting of soil trend that farm crop arable land is formed increases the weight of, and causes soil water sorption amount to weaken, in water spray irrigation process; moisture flows away; northern area staple crops Maize Absorption moisture reduces, and affects crop growth, and large water gaging is irrigated in addition; the short crisis of exacerbate water resource; how to improve salting of soil degree, adjustment Soil structure hardens, and improves the subject matter that ventilation property becomes current corn plant growth.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of modifying agent for corn soil and manufacture method thereof, the effect such as realize water conservation, fertilizer conservation, salt reduction, pressure alkali, loosen the soil.Its main method is: be aggregated in by sodium acrylate graft on weathered coal, then with attapulgite with phosphogypsum is composite makes alkaline land modifying agent.Its cardinal principle is: cemented out by the sodium ion being adsorbed on soil colloids by the ion exchange of phosphogypsum; Water retention is played by the sodium polyacrylate be grafted on weathered coal; By phosphogypsum by the carbanion solidification (CaSO in deep subsoil water body

3), thus soil pH value falls; Soil pH is reduced and can chessom by the acidity effect of weathered coal; The effect keeping chemical fertilizer nutrient is played by attapulgite; Bentoniticly to add, the pH value of soil can better be adjusted, effectively can improve soil and cause soil compaction because of saline and alkaline degree, improve Crop Root and tie up to the inner permeation functions of soil.
The present invention is achieved by the following technical solutions, a kind of modifying agent for corn soil, by attapulgite, phosphogypsum, weathered coal-sodium polyacrylate mixture, wilkinite forms, it is characterized in that: according to weighing scale, 5-7 part attapulgite, by 1-2 part phosphogypsum, 1-3 part weathered coal-sodium polyacrylate mixture, the wilkinite of 1-2 part mixes and forms, described attapulgite fineness is 250-350 order, the fineness of described phosphogypsum is 250-350 order, described weathered coal-sodium polyacrylate mixture is by weight, by the sodium polyacrylate Homogeneous phase mixing of the weathered coal of 7 parts and 3 parts, then be added to the water and be made into the suspension liquid that concentration is 70g/L, at 25-27 DEG C, stir 25 minutes, thus by sodium acrylate graft copolymerization at weathered coal on the surface, afterwards in 60 degrees Celsius of dryings, be crushed to 250-300 order to obtain, described bentonitic fineness is 250-350 order.
For a modifying agent manufacture method for corn soil, it is characterized in that, comprise the steps:
(1) attapulgite is crushed to 250-350 order dry powder and irradiates under gamma ray (2-4MeV, 20-40kGy) and obtain stand-by in 10-12 minute;
(2) to be broken to 250-350 order stand-by for phosphogypsum powder;
(3) weathered coal-sodium polyacrylate mixture is by the weathered coal of 7 parts and the sodium polyacrylate Homogeneous phase mixing of 3 parts, then be added to the water and be made into the suspension liquid that concentration is 70g/L, at 25-27 DEG C, stir 25 minutes, thus by sodium acrylate graft copolymerization at weathered coal on the surface, dry, pulverize to 250-300 order in 60 degrees Celsius afterwards obtains stand-by;
(4) most 250-350 order is stand-by for bentonitic finess disintegrating;
(5) by weight, the wilkinite 1-2 part Homogeneous phase mixing in the weathered coal in the attapulgite 5-7 part in (1), the phosphogypsum 1-2 part in (2), (3)-sodium polyacrylate mixture 1-3 part, (4) is obtained this modifying agent.
The modifying agent obtained by weight, the modifying agent obtained is added in fertilizer or urea or Chemical Mixed Fertilizer according to 5-20% ratio, namely granulation obtains alkaline land improving fertilizer, alkaline land improving urea and alkaline land improving Chemical Mixed Fertilizer, the modifying agent obtained evenly is used according to every mu of 10-13kg consumption, the consumption of obtained improving fertilizer according to every mu of 50-55kg is evenly used.
The present invention has the following advantages compared to existing technology:
(1) the present invention is compared with common chemical fertilizer, apply fertilizer Deng nutrient, soil humidity more than 10% can be increased, reduce soil and be harmful to salinity (sodium ion and carbanion etc.) more than 10%, improve determining cation exchange capacity of soil more than 5%, reduce nutrient loss more than 15%, make crop yield more than 10%, the multiple efficacies such as there is significant water conservation, fertilizer conservation, salt reduction, pressure alkali, loosen the soil; (2) phosphogypsum adopted in the present invention is mainly the by product that fertilizer plant produces phosphate fertilizer, compared with the desulfurated plaster used in existing alkaline land modifying agent patent, there is reserves large (about more than 10 times), the large advantage of cost low (low more than 50%) two; (3) weathered coal adopted in the present invention, compared with humic acid in existing alkaline land modifying agent patent, has the advantages such as reserves are large, cost is low.
