Description
Technical field
The present invention relates to Nutrition Soil, be specifically related to the production method of a kind of sepiolite charing Nutrition Soil.
Background technology
The Nutrition Soil raw material that existing flower plants and nursery stock uses is formulated by material mixing such as mountain mud, garden mould, pond sludge, peat soil, river sand, plant ash, wood chip, agricultural crop straw, mushroom cultivation dead meal and soil ulmin mostly, these Nutrition Soils are not through reasonably preparing burden and sterilization, preserve moisture and fertility ability, permeability is bad, easily harden, mineral matter nutritional in Nutrition Soil is difficult to be absorbed by flower plants and nursery stock, flower plants and nursery stock also can be subject to the virus and bacteria in soil and newly sprout the infringement of weeds, is unfavorable for that the normal growth of flower plants and nursery stock is grown.
Phosphorus and potassium are all that flower plants and nursery stock grows required nutritive element, although containing a certain amount of phosphorus and potassium in Nutrition Soil, but major part belongs to late effect property phosphorus and potassium, directly can not be absorbed by flower plants and nursery stock root system, cause flower plants and nursery stock poor growth, the normal growth affecting flower plants and nursery stock is grown, therefore, phosphorus in Nutrition Soil and potassium, need be converted into solubility rapid available phosphorus and potassium directly could be absorbed by plant.
The clay of sepiolite clay to be a kind of with sepiolite be main component, association has attapulgite, montmorillonite, talcum etc., and non-clay mineral tramp material then has quartz, calcite, lazurite etc.
Summary of the invention
The object of the invention is to overcome weak point in prior art, provide a kind of sepiolite to carbonize the production method of Nutrition Soil.
The production method of sepiolite charing Nutrition Soil: first the batching of sepiolite charing soil stirred and be squeezed into platy shaped particle, charing is treated to sepiolite charing soil, then sepiolite is carbonized batching granulation and the sterilizing of Nutrition Soil, is packaged as the finished product of sepiolite charing Nutrition Soil.
Sepiolite charing Nutrition Soil is made up of the waste after sepiolite, active white clay waste slag, zeolite, pulverizing, the waste after bubble system, urea, calcium superphosphate, potassium sulfate, expanded vermiculite, pearlstone, unslaked lime, ferrous sulfate and High hydrophilous resin.
Sepiolite is the moisture magnesia silicate clay mineral of a kind of natural fiber, the structures shape that sepiolite is special it there is good physical and chemical performance, preferably rheological, thermostability, porousness, strong adsorptivity and the large specific surface of improvement can be processed, the present invention selects particle fineness≤0.5 millimeter of sepiolite.
Atlapulgite is with attapulgite clay, wilkinite and gac for raw material, the sorbent material that the activity processed through acidification is higher, is widely used in grease-decolor; Atlapulgite after decolouring loses activity, can not regenerate and reuse, become a kind of auburn active white clay waste slag, in active white clay waste slag, oil length is up to 15 ~ 40%, active white clay waste slag is after again recycling, still remain the grease of 5 ~ 25%, these active white clay waste slags not only can produce spontaneous combustion, and serious environment pollution, at present, most of oil factory adopts water to spray or melt pit is buried, and as offal treatment, causes resource to waste.
Zeolite is modified through Overheating Treatment, and the effective pore radius of zeolite obtains increase, being agriculturally used as soil improvement agent, can play the effect of fertilizer conservation, water conservation and slow releasing.The present invention selects the zeolite after pulverizing, particle fineness≤0.5 millimeter of zeolite.
The stalk of a large amount of farm crop, wood chip, bamboo bits, leaf and bark the like waste, be discarded in around farmland or roadside, mostly burned fall, severe contamination Air quality; Waste after pulverizing pulverizes after the stalk of farm crop, wood chip, bamboo bits and leaf the like waste being dried, and the present invention selects waste length≤25 millimeter after pulverizing.
Expanded vermiculite after high-temperature roasting, its volume energy undergoes rapid expansion several times to tens times, the vermiculite after volumetric expansion, expanded vermiculite, is one of the lightest in the world mineral; Expanded vermiculite is used as soil improvement agent, can improve the structure of soil, and water storage preserves soil moisture, and improves the ventilation property of soil and aquosity, plays the multiple actions such as fertilizer conservation, water conservation, water storage, ventilative and mineral manure.The present invention selects the expanded vermiculite after pulverizing, particle fineness≤1 millimeter of expanded vermiculite.
Perlite becomes a kind of lightweight, multifunctional novel shaped material through expansion, have the features such as apparent density is light, thermal conductivity is low, chemical stability is good, and pearlstone is fertilizer conservation, water conservation, aseptic, good permeability on agricultural, gardens.The present invention selects the pearlstone after pulverizing, particle fineness≤2 millimeter of pearlstone.
Urea is the nitrogenous fertilizer that nitrogen content is the highest, and as a kind of neutral fertilizer, urea is applicable to various soil and plant, and it is easily preserved, easy to use, little to the destruction of soil, is a kind of chemical nitrogen fertilizer that current usage quantity is larger.Nitrogen content is about 46.67%, and urea is soluble in water, and solubilized 105 grams in 100 ml waters 20 DEG C time, the aqueous solution is neutral reaction.
Phosphate fertilizer has water soluble phosphorous fertilizer, citrate acid soluble phosphatic fertilizer and difficultly soluble phosphatic fertilizer, ssp dnab of the present invention, containing effective Vanadium Pentoxide in FLAKES 14 ~ 20%, belongs to water soluble quick-acting phosphate fertilizer.
Potash fertilizer mainly contains Repone K, potassium sulfate, plant ash, kainite, potassium phosphate,monobasic etc., greatly can be water-soluble, and fertilizer efficiency is very fast, and by soil absorption, not easily can run off.The present invention selects potassium sulfate, containing potassium oxide 50 ~ 54%.
Urea, calcium superphosphate and potassium sulfate are all the chemical fertilizer agriculturally commonly used.
The main component of unslaked lime is calcium oxide, general in block, pure is white, containing being light gray or faint yellow during impurity, calcium oxide and water effect generate calcium hydroxide, and release heat, in alkalescence, pH value in the present invention for regulating sepiolite to carbonize Nutrition Soil, the present invention selects the unslaked lime after pulverizing, particle fineness≤0.5 millimeter of unslaked lime.
Ferrous sulfate is pale green crystals, the ferrous sulfate of 10% aqueous solution is acid to reindeer moss, pH value is about 3.7, in the present invention for regulating zeolite to carbonize the pH value of Nutrition Soil and the supplement as plant ferro element, physiological disturbance is there is in control plant because of iron deficiency, make leaf look chlorosis, can also be used to kill liver moss.
The water absorbent rate of High hydrophilous resin can reach hundreds of times even thousands of times of own wt, and the present invention selects the water absorbent rate of High hydrophilous resin to be 100 ~ 300 times.
