Description
The invention provides a kind of inorganic soil regulating agent and manufacture method.This inorganic soil regulating agent is suitable for that water is planted or drought is planted the crop field and used.
Outside contained essential element de-carbon, the oxygen of crop can absorb from air, other big or middle element such as phosphorus, calcium, magnesium, sulphur etc. all absorbed from soil as iron, zinc, copper, chlorine etc. with trace element.Crop is not only determined by soil element content and form the absorption of above-mentioned element, but also is subjected to influence of various factors such as soil acidity or alkalinity PH and redox potential En.Because elements such as the oxygen in the soil, nitrogen, sulphur, iron are easy to take place redox reaction, soil has certain redox potential En, and it influence crop to trace elements absorbed such as iron, sulphur, thus regulate P in soil H and En significant.
Existing method of regulating P in soil H has: 1. WATER-WASHING METHOD.Dilute with water is also removed soil partly acid, alkaloid substance; 2. waterflooding relieving haperacidity method.The oxidation of sulphur in the control soil reduces and produces acid; 3. sulphur is executed in semi dry cultivation, promotes soil to produce acid; 4. neutralisation.With molten fertile, the physiological alkalinity chemical fertilizer of lime, stove, as alkaline matters such as plant ash, scorched clay dusts, in and acid; Use physiological acidic fertilizer, as in ammonium sulfate, the gypsum etc. and alkaline substance; The applications of farmyard manure material also has the effect of certain buffering soil acidity or alkalinity.But also there is not the special-purpose regulating agent special of regulating soil redox potential.
Above method is to the comprehensive adjustment poor performance of P in soil H and En, use inconvenient, effect is also undesirable, especially to potential of hydrogen PH and the bigger low-yield lands of redox potential En deviation such as cold-water paddy field, mud field, pantothenic acid field, poison fields, ore deposit, not only investment cost is big, and be difficult for grasping usage quantity, effect is poorer.
The object of the present invention is to provide a kind of inorganic soil regulating agent and the manufacture method thereof good to the comprehensive adjustment performance of soil acidity or alkalinity PH and soil redox potential En.This conditioning agent can effectively improve soil physico-chemical characteristic, and fertilizer efficiency is provided, and reaches the purpose of increasing both production and income.
The present invention is achieved in that by potential of hydrogen PH conditioning agent (P), contains (weight %) in the inorganic soil regulating agent that redox potential En conditioning agent (E) is formed to be:
60～80% potential of hydrogen PH conditioning agents (P)
15～35% redox potential En conditioning agents (E)
5～10% additives (T)
The each component summation is 100%.
Potential of hydrogen PH conditioning agent (P) is: rhombspar or calcium monofluorophosphate or Wingdale or yellow phosphorus furnace slag.
Redox potential En conditioning agent (E) is: ammonium nitrate or SODIUMNITRATE.
Additive (T) is: urea or calcium chloride eight ammonia mixture CaCINH.
The manufacture method of producing inorganic soil regulating agent is as follows:
1, with conditioning agent (P) drying and crushing, ball milling becomes the above fineness powder of 80 orders, and conditioning agent (E) is through crushing screening; Additive (T) is through crushing screening.
2, conditioning agent (P) and conditioning agent (E) are mixed in proportion, and in certain temperature, constantly stir, the cooling back adds the additive (T) of crushing screening, restir is even, be cooled to normal temperature after, pulverize again, promptly obtain inorganic soil regulating agent.
Method I: drying is pulverized, ball milling becomes the rhombspar 60～80% of the above fineness of 80 orders and ammonium nitrate 15～35% through crushing screening to mix, and under 169～210 ℃ of temperature, constantly stir, when waiting to cool to below 160 ℃, add CaCINH or urea 5～10%, and in 30～150 ℃ of temperature, continue stirring and processing, the back discharging stirs, through being cooled to normal temperature, pulverize again, promptly get inorganic soil regulating agent.
Method II: drying is pulverized, ball milling becomes the calcium monofluorophosphate 60～80% of the above fineness of 80 orders and ammonium nitrate 15～35% through crushing screening to mix, and under 169～210 ℃ of temperature, constantly stir, when waiting to cool to below 160 ℃, add CaCINH or urea 5～10%, and in 30～150 ℃ of temperature, continue stirring and processing, the back discharging stirs, through being cooled to normal temperature, pulverize again, promptly get inorganic soil regulating agent.
Method III: drying is pulverized, ball milling becomes the yellow phosphorus furnace slag 60～80% of the above fineness of 80 orders and SODIUMNITRATE 15～35% through crushing screening to mix, and under 169～210 ℃ of temperature, constantly stir, when waiting to cool to below 160 ℃, add urea 5～10%, and in 30～150 ℃ of temperature, continue stirring and processing, the back discharging stirs, through being cooled to normal temperature, pulverize again, promptly get inorganic soil regulating agent.
Method IV: drying is pulverized, ball milling becomes the Wingdale 60～80% of the above fineness of 80 orders and ammonium nitrate 15～35% through crushing screening to mix, and under 169～210 ℃ of temperature, constantly stir, when waiting to cool to below 160 ℃, add urea or CaCINH5～10%, and in 30～150 ℃ of temperature, continue stirring and processing, the back discharging stirs, through being cooled to normal temperature, pulverize again, promptly get inorganic soil regulating agent.
This inorganic soil regulating agent is a kind of neutral inorganic mixture, therefore, can not cause soil to produce acid evil or alkali evil.This is because this conditioning agent is not common direct acid, alkali neutralization reaction in soil, but by carbonate, phosphoric acid salt etc. replacement(metathesis)reaction takes place lentamente, keeps P in soil H in 6 ± 0.5 optimum range.This inorganic soil regulating agent can also replenish a certain amount of nitrogen, phosphorus, calcium, magnesium, manganese, zinc element to soil, and its actual comprehensive fertilizer efficiency (increasing both production and income) reaches equivalent urea efficiency level, and cost is lower.Because this conditioning agent deferred reaction in soil, thermopositive reaction slowly takes place in release of carbon dioxide, increases cation concns such as calcium, magnesium, reduce the concentration factor of water, reduce specific heat capacity, so, help the crop photosynthesis effect, be easy to improve ground temperature, help plant growth, and improve Soil structure, reduce the soil compaction phenomenon.Also help and improve and stable soil redox potential En.
This conditioning agent is particularly useful for southern acid soil or redox potential En soil on the low side, especially to multiple low-yield lands such as cold-water paddy field, mud field, pantothenic acid field, poison fields, ore deposit, can significantly improve its soil physico-chemical characteristic after the use, especially after polynary composite trace element foliar nutrient is used in merging, can obtain high yield.
This conditioning agent manufacture method is simple, and cost is lower, is easy to promote.
