Abstract
The invention relates to a saline-alkali soil modifier and a preparation method and application of the saline-alkali soil modifier. The modifier is prepared from charcoal, ardealite, ammonuim humate, urea and citric acid. The saline-alkali soil modifier is obtained through fully mixing the charcoal, ardealite, ammonuim humate, urea and citric acid according to the proportions, adding water, mixing uniformly, pelleting through a conventional pelletizer, drying and dehydrating. The obtained saline-alkali soil modifier is applied in Kashi Prefecture, Hotan Prefecture, Akesu Prefecture and Changji Prefecture in Xinjiang Province respectively in 2010 and 2011 to conduct the contrast test in the fields, after each of the test sites is cultivated for a year, the total salt content of the soil is decreased by 36.1%-58.6%, the pH of the soil is decreased by 0.07-0.43, and the yield rate of the crop yield is up to 9.9%-22.3%. The saline-alkali soil modifier provided in the invention is simple in preparation method and relatively low in application cost, and can effectively reduce the total salt and the pH of the soil and remarkably increase the crop yield. The disadvantages and the defects of the existing modifier are overcome.

Background technology
The soil salinization is the MAIN SOILS problem that China faces, and there are the salt wasteland that surpasses 2,000 ten thousand hectares and 6,700,000 hectares salinification soil in China, and these soils can not normally be cultivated.Salt affected soil refers to contain in the soil harmful salts such as the muriate, vitriol, hydrocarbonate of potassium, sodium, calcium magnesium.The salt affected soil principal character is that the pH value is higher, contains harmful salinity, seriously restricts the growth of plant; Wherein sodium ion has the effect of severe inhibition and poisonous plant root growth.How by simple method, reduce saltings saltiness, restore vegetation fast and become the difficult problem that government and scientist face.
At present, the method in improvement saltings has following several:
Application number: 200810153822.8, open day: disclosed a kind of alkaline land soil repair agent on December 8th, 2008, its by desulfurated plaster, natural organic substance, microorganism fertilizer and inorganic nutrients with 60-70:25-35: 1-4: the 3-6 weight ratio is formed, and the sulfate dihydrate calcium contents is more than 80% in the desulfurated plaster; Natural organic substance is made up of with 1.0: 0.93 weight ratio weathered coal and the peat composed of rotten mosses; Effective bacterial content is 2.0 hundred million/gram in the microorganism fertilizer; Inorganic nutrients is made up of with 1.0: 2.42: 0.75 weight ratio urea, calcium superphosphate and Repone K.Renovation agent of the present invention can utilize the calcium ion in the desulfurated plaster to replace sodium ion in the soil, reduces basicity in the soil with this, and also for crop provides calcium and element sulphur, natural organic substance can reduce and regulate salt content and the basicity of soil.
Application number: 201210286131, open day: on December 05th, 2012 disclosed and has related to a kind of soil improvement agent and preparation method thereof, each parts by weight of raw materials of soil improvement agent is as follows: fish aquatic products processing waste powder 1-10 part, oyster shell whiting 10-20 part, straw powder 1-10 part, diatomite 1-10 part, high-activity biological preparation 0.1-2 part, sour 2-5 part, medical stone powder 1-10 part, raw material is added mixing tank, fully mix, namely.
Application number: 201210203263, open day: disclosed a kind of saline-alkali soil conditioner and preparation method thereof and application on November 07th, 2012, relate to a kind of saline-alkali soil conditioner and preparation method and utilisation technology, made by following raw materials by weight percent dissolving: poly-maleic acid 0.4-8.0; Sodium dodecylbenzene sulfonate 1.1-2.5; Poly aspartic acid 0.3-18; Oxysuccinic acid 0.3-5; Oxalic acid 0.3-18; Ammonium sulfate 0.1-1; Plant growth agent 0.3-2; Spreader-sticker 0.1-2; Toluene silicone oil 0.001-0.05; Water surplus.Application method is: join after the dilution in the drip irrigation jar soil dripped and execute.
Application number: 201210103341.2, open day: disclosed on April 11st, 2012 a kind of in salt affected soil improvement material and application thereof, belong to the soil improvement technology, solve salt affected soil because its densification, hard characteristic, bring to plant germination and to hinder, high pH can reduce the necessary nutrient of plant again, makes the problem that potential nutritive element such as charcoal, nitrogen descends in the soil.A kind of salt affected soil is improved material, comprises each component of following weight part: sulphur 15-60, ammonium humate 15-60, husk class residue 15-40.
At present, be to adopt soil to apply the method for modifying agent for the chemical process of administering the saltings.Existing soil improvement agent kind is mainly solid and liquid two big classes.Though these modifying agents have positive effect to the improvement alkaline land soil, be subjected to obtain large-area popularization as the restriction of complex manufacturing, cost height and some other conditions.
Summary of the invention
The objective of the invention is to; a kind of alkaline land modifying agent is provided; this modifying agent is to be made by charcoal, phosphogypsum, ammonium humate, urea and citric acid; adopt in proportion with behind its abundant mixing; add water and mix; carry out drying again after the tablets press granulation of routine, dehydration can obtain alkaline land modifying agent.And with the alkaline land modifying agent that obtains respectively at 2010 and 2011 in the Kashi area, Hotan Prefecture, Aksu Prefecture, area, Changji carried out the field simultaneous test, each test site farming 1 year, soil total salt content decline 36.1%-58.6%, pH decreased 0.07-0.43, the crop yield amount of increase in production reaches 9.9%-22.3%.Alkaline land modifying agent making method of the present invention is simple, and application cost is lower, can effectively reduce the total salt of soil, pH, and obviously improves crop yield.Overcome the shortcoming and defect of existing modifying agent.
A kind of alkaline land modifying agent of the present invention, this modifying agent are to be by weight ratio: charcoal 23-78%, phosphogypsum 15-55%, ammonium humate 5-15%, urea 1.5-5% and citric acid 0.5-2.0% make.
