A saline-alkali soil improver is composed of phosphogypsum, attapulgite, a weathered coal-sodium polyacrylate compound, black alum and a trace element compound. The method is characterized in that: by weight, the soil improver is formed by mixing 1-3 parts of phosphogypsum, 4-5 parts of attapulgite, 1-3 parts of the weathered coal-sodium polyacrylate compound, 1-2 parts of black alum and 1-2 parts of the trace element compound, attapulgite, sodium acrylate and other materials are subjected to modification, grafting and polymerization, the obtained improver has the efficacy of water retention, fertilizer maintenance, salt reduction, alkali decrease, soil loosening and the like, accordingly can improve rice field saline-alkali soil, and can be added into a fertilizer to prepare saline-alkali soil improvement fertilizer. Compared with existing methods, the method provided by the invention has the advantages of low cost, abundant raw materials and high efficiency, etc.
Description
Technical field
What the present invention relates to is a kind of modifying agent improving alkaline land soil performance.
Background technology
Salting of soil is a global difficult problem, and be also the major obstacle factor that restriction China's agricultural development and integration capability improve, the deterioration of the ecological environment that salinization brings, more can affect the space that the people depends on for existence and development always.So saltings control and exploitation are the problems that irrigated area agricultural development can not be ignored, the grain drop in production such as the paddy rice that agriculture plantation causes because of salinization.China's North China's modern agriculture, due to the excessive use of chemical fertilizer, causes Pedotransfer function to aggravate, and hardens serious, make salinization, alkali-affected soil constantly expands, aggravate, rice terrace is due to the needs of rice growing season, and field few time cuts off the water supply, but most of irrigation district adopts extensive style pouring farmland, in addition temperature is higher, and evaporation is very fast, and rainfall is less, make deep soil saline and alkaline on to move table poly-, cause primary salinization, rice yield declines, and salting of soil is on the rise.
At present, saline and alkali land improvement method mainly contains Physical (wholelyly and water resources industry: CN201010256362.9, CN200710179269.0 etc.), biological process (microbial inoculum: CN201010131080.6, CN201310114401.5 etc.) and chemical method (modifying agent: the CN201110095321.0 such as desulfurated plaster, sulfuric acid, furfural dregs, humic acid, animal excrement, CN200610017147.7, CN03138949.X etc.) etc.Although these measures are effective under certain condition, but separately there is limitation: water conservancy law and chemical amendments at substantial manpower and materials, phytoremediation longer and climate condition restriction consuming time, is all difficult to implement on a large scale, can not meets current China's agricultural development needs.
Close to the most existing alkaline land modifying agent of the present invention such as notification number be: 103937507A application discloses " a kind of alkaline land modifying agent, preparation method and using method thereof ", this product and production thereof, using method are have good effect at adjustment alkaline land soil saline alkali, but, this kind of product is confined to improve crop growth environment, but effectively cannot improve the ventilation property of root system plant in soil.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide the modification method of a kind of rice in saline-alkali field plantation, 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; Black alum can level of alkalinity effectively in sweetening of the soil, effectively can improve soil because of saline and alkaline degree causes soil compaction, improve Crop Root and tie up to the inner permeation functions of soil, the usage quantity of trace compound is little, but trace compound effectively can supplement and meet farm crop whole breeding times to the demand of multiple nutrient, accomplish balance fertilizing, trace element has growing of promotion crop, improve photosynthetic utilization ratio, improve the per unit area yield of paddy rice, though consumption is little, play an important role.
The present invention is achieved by the following technical solutions, a kind of modification method of rice in saline-alkali field plantation, be made up of phosphogypsum, attapulgite, weathered coal-sodium polyacrylate mixture, black alum and trace compound, it is characterized in that: according to weighing scale, mixed by 1-3 part phosphogypsum, 4-5 part attapulgite, 1-3 part weathered coal-sodium polyacrylate mixture, the black alum of 1-2 part and the trace compound of 1-2 part and form, its step is as follows:
(1) phosphogypsum powder is broken to 150-180 order stand-by;
(2) attapulgite is crushed to 150-180 order dry powder to irradiate under gamma ray (3MeV, 30kGy) and obtain stand-by in 20-30 minute;
(3) weathered coal-sodium polyacrylate mixture is by the weathered coal of 9 parts and the sodium polyacrylate Homogeneous phase mixing of 4 parts, then be added to the water and be made into the suspension liquid that concentration is 90g/L, at 40 DEG C, stir 10 minutes, thus by sodium acrylate graft copolymerization at weathered coal on the surface, dry, pulverize to 150-180 order in 70 degrees Celsius afterwards obtains stand-by;
(4) by the finess disintegrating of black alum, most 150-180 order is stand-by;
(5) trace compound is mixed by the borax of 5-7 part ammonium molybdate, 20-30 part, the zinc sulfate of 10-15 part by weight, and the fineness of trace compound is 150-180 order
(6) by weight, the trace compound Homogeneous phase mixing of the black alum 1-2 part in weathered coal-sodium polyacrylate mixture 1-3 part, (4) in the phosphogypsum 1-3 part in (1), the attapulgite 4-5 part in (2), (3) is obtained this modifying agent, the modifying agent obtained evenly is spread fertilizer over the fields on water paddy soil surface according to every mu of 15-20kg consumption, then ploughs.
A kind of modification method of rice in saline-alkali field plantation, it is characterized in that: 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, obtained improving fertilizer is evenly spread fertilizer over the fields on water paddy soil surface according to the consumption of every mu of 40-60kg, then ploughs.
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.
