Description
Technical field
The present invention relates to technical field of land improvement, more particularly to a kind of saline-alkali soil conditioner and application method.
Background technology
Due to natural and artificial factor, the salt affected soil area in China is huge, and according to statistics, China's saline-alkali soil area reaches
99130000 hectares, as can which part saline-alkali soil is improved, become the soil of suitable farming, anticipate for China's agricultural production
Justice is great.
The modification method of saline-alkali soil is very much, mainly has：(1) landform, soil removal and replacement are raised in Physical, prepartion of land, chesson
Deng；(2) modifying agent such as chemical method, gypsuming, humic acid, peat；(3) bioanalysis, plants salt-tolerant plant or using biology
Bacterial manure；(4) water conservancy law：Salt content is reduced by the method for salt discharge of pouring water.There are certain deficiency, such as soil to put down for the above method
Whole to fail to solve the problems, such as that soil salt content is high at all, soil replacement method is of high cost, and humic acid, peat are valuable natural resources, no
It is renewable, plantation salt-tolerant plant cycle length, the problems such as water conservancy law needs great lot of water resources.
For the features such as salt-soda soil salt content is high, pH value is high, the content of organic matter is low and soil texture is poor, workers and peasants are made full use of
Industry discarded object is raw material, and certain organic acid of arranging in pairs or groups, prepares soil conditioner, can play reduction soil salt content, reduces pH
Value, the effect of improving soil organic matter content and improve soil texture, has for salt affected soil improvement and follow-up utilization
It is with practical value great.Aqueous citric acid solution is used merely, can not be further although the effect for reducing pH value can be played
The salt content in soil is reduced, can not also change the characteristics of soil organic matter content is low and soil texture is poor
The content of the invention
The object of the present invention is to provide a kind of saline-alkali soil conditioner, which is discarded using a large amount of industrial or agricultural
Thing, has advantage of low cost, and product has reduction soil salt content, reduces pH value, improves soil organic matter content and changes
The effect of kind soil texture.
A kind of saline-alkali soil conditioner provided by the invention, in parts by weight, the saline-alkali soil conditioner raw material：Power plant
3~10 parts of desulfurated plaster, 0~10 part of blast furnace ground-slag, 80~95 parts of acid-sludge, mass percentage for 1% aqueous citric acid solution 3~
10 parts.
Preferably, in parts by weight, the saline-alkali soil conditioner raw material：3~10 parts of power plant desulfurization gypsum, blast furnace ground-slag
2~10 parts, 80~95 parts of acid-sludge, mass percentage is 3~10 parts of 1% aqueous citric acid solution.Add blast furnace ground-slag and electricity
Factory's desulfurated plaster is engaged, and the calcium ion in desulfurated plaster and blast furnace ground-slag can accelerate the sodium in saline-alkali soil to interact, drop
Low soil salt content, while the crumb structure of soil can also be improved, increase soil porosity, accelerate salt discharge efficiency
The acid-sludge is 100 with the weight ratio that mass percentage is 1% aqueous citric acid solution：5-6.Since acid-sludge is acid
Property, and containing abundant organic matter, have effects that to increase soil fertility；Acid-sludge is used cooperatively with aqueous citric acid solution,
The effect of pH value is adjusted with can play for a long time in short term.Particularly when acid-sludge and mass percentage are 1% aqueous citric acid solution
Weight ratio be 100：During 5-6, effect is more excellent.
Wherein, the power plant desulfurization gypsum is coal-burning power plant's wet process of FGD accessory substance, and water content is 10~30%, is done
Calcium sulphate dihydrate CaSO in base4·2H2O content is not less than 90%.
Wherein, the blast furnace ground-slag is the discarded object that iron-smelting process produces, and is process by drying, iron removaling and grinding,
It is more than 200 mesh of fineness, wherein SiO2Content is not less than 30%, and CaO content is not less than 35%, and content of MgO is not less than 5%.
Wherein, the acid-sludge is makes the discarded object that vinegar technique produces, water content 40~50%, the content of organic matter 40% with
On.
Wherein, 1% citric acid solution, using citric acid and tap water as raw material, proportionally dissolves and stirs
It is even.
It is a further object to provide a kind of application method of saline-alkali soil conditioner.
Wherein, the sowing amount of saline-alkali soil conditioner is 10~30 tons/mu.
Wherein, the application method is：Required raw material is ready to according to proportioning, according to desulfurated plaster, blast furnace ground-slag,
The order of acid-sludge and citric acid solution imposes on soil surface successively, is uniformly mixed raw material with soil using machinery.
By the implementation of the present invention, following effect can be played：Soil salt content is reduced, reduces pH value, improving soil has
The effect of machine matter content and improvement soil texture.
This product contains the effect of certain acidic materials can play reduction soil pH value within a short period of time；Desulfurization stone
Calcium ion in cream and blast furnace ground-slag can be interacted with the sodium in saline-alkali soil, reduce soil salt content, while can also improve
The crumb structure of soil, increases soil porosity, accelerates salt discharge efficiency；Acid-sludge contains abundant organic matter, has and improves soil
The effect of fertility；Contain the middle trace element needed for the plant growths such as abundant silicon-calcium-magnesium in blast furnace ground-slag, have and improve plant
Resistance and the function of promoting plant growth.This product is protected using solid waste as primary raw material for resource regeneration and environment
Protector has positive effect, while raw material is easy to get, and preparation process is simple, and technique is controllable.
