Abstract
The invention provides an ecological slow release sterilizer and a preparation method of the ecological slow release sterilizer. The ecological slow release sterilizer comprises a coating film granular nitrogenous fertilizer carrier and a nitrogen phosphorus and potassium granular fertilizer carrier. By adopting the ecological slow release fertilizer, the demand of the crops on nitrogen phosphorus and potassium at the earlier phase is met, demand of the crops on the nitrogen in the medium phase and the later phase is also met, the operations of topdressing is omitted, the farming is convenient to carry out, and the work load is reduced; moreover, an empty shell with the nutrient released in the coating film can be used for storing water and preserving soil moisture, and also play a role in ventilating and maintaining fertilizer, so that the soil which is hardened for a long time can be loosened, and the harmful substances in the soil can be removed. Ecological organic materials added to a shell bring influence on the transfer capacity of the pollutant (heavy metal, polycyclic aromatic hydrocarbon and pesticide) and the bio-availability of nutrient elements such as C, N, S and P, and also serve as important impact elements in mineral weathering, soil-forming process, growth and metabolism of microorganism, organic matter decomposition of soil, and transfer process; B and Zn in the coating film can condition the nutrient balance of the crops, improves the ecological relationship between the crop and the environment, and improves the output and the quality. By adopting the coating film fertilizer particle, the amount of the released nutrition can be controlled, the utilization rate of the fertilizer can be increased, the property, manpower and the time can be saved, and the quality and the efficiency can be improved.
Description
Affiliated technical field
The present invention relates to a kind of composite fertilizer, it is characterized in that by two kinds of granulometric composition a kind of not coated granule and a kind of coated granule, orange and white.Be rich in many kinds of substance in film and nutrient-lapsed time length can be removed the ecological slow-release fertilizer of link and preparation method thereof that topdresses from
Background technology
At present, known composite fertilizer is in a kind of chemical fertilizer, contains two kinds and two or more fertilizer in nitrogen, phosphorus, potassium three elements.Composite fertilizer has that nutrient content is high, minor component is few and the advantage such as physical behavior is good.Composite fertilizer's fertilizer efficiency is long, is fit to do base manure, decomposes slowlyer, when sowing is made the crop of base fertilizer of composite fertilizer, because Different Crop ground regulation of fertilizer requirement needs in time to replenish instant nitrogenousfertilizer when topdressing, to satisfy the crop alimentary needs.But long-time field test shows with result of study, and the nutrients ratio of composite fertilizer is always fixed, and different soils, required nutritive element kind, quantity and the ratio of Different Crop are various.Need the farm crop of nitrogen for happiness phosphorus, potassium, the needs that the content of composite fertilizer's nitrogen is on the low side can't satisfy farm crop also needs topdress again, i.e. expensive not only effort but also time-consuming.After being manured into soil, the utilization absorbed by crops of 30%-50% energy is only arranged, rest part has lost in vain.Arable soil is seriously polluted by heavy metal, fertilizer damage at present; Soil generally lacks organic matter, middle trace element; Nitrogen loss more than 50%; Continuous cropping kind plant causes soil-borne disease to increase the weight of; Soil fertility descends, and productivity descends.
Summary of the invention
In order to improve the nitrogen element, remove the link of topdressing from, avoid the loss of nutrient and improve soil, the invention provides a kind of ecological slow-release fertilizer, conventional composite fertilizer can't satisfy crop mid-term and later stage to the needs of nutrient, and the ecological slow-release fertilizer particle of this invention is double-colored particle, orange and white.Two kinds of particles are divided into coated granule and coated granule not.The particle of coating is not the fertile carrier of nitrogen phosphorus k particle, and the particle of coating is nitrogen granular fertilizer carrier, satisfies crop mid-term and later stage nutritional need, removes the link of topdressing from.Coating can be controlled the loss of nutrient, add trace element in ecological organic matter and boron, zinc in putamina, ghost after nutrient releases can be retained and conserved soil moisture, can play again ventilation fertilizer conservation function, make the soil that hardens for a long time become loose and can reject objectionable constituent in soil, fertilizer efficiency is slowly steady, decompose slow than chemical fertilizer of simple substance, leaching loss of nutrient is few, and utilization ratio is high, is suitable for doing base manure.
The technical solution adopted for the present invention to solve the technical problems is: be the decomposable slow release-controlled film of nitrogen granular fertilizer carrier bag one deck, namely add solvability ecological organic, ecological organic matter not only can affect the transfer ability of pollutent (heavy metal, many cyclophanes footpath, agricultural chemicals) and the biological effectiveness of the nutritive elements such as C, N, S and P, but also is the important factor in order of Mineral Weathering, soil-forming process and microbial growth metabolism, decomposition of soil organic matter and conversion process; In B, Zn, trace element, directly be formulated in B, Zn in nitrogen granular fertilizer carrier film and use, and can regulate Crop nutrient balance, improves crop-environmental ecology relation, improves the yield and quality; Modified urea-formaldehyde resin, the modified urea-formaldehyde resin of this invention use are that hot water dissolving's component N (HWSN, 100 ℃) is methene urea and medium chain polymkeric substance, and the N in this component can slowly be discharged in soil.The weight ratio of ecological organic matter, boron, zinc, modified urea-formaldehyde resin is 0.01: 0.0025: 0.0025: 0.04 is 4: 1: 1: 16.After nitrogen granular fertilizer carrier coating is complete, add the fertile carrier of nitrogen phosphorus k particle in encapsulation tool.The ratio of the fertile carrier of coating nitrogen granular fertilizer carrier and nitrogen phosphorus k particle is come the different ratio of producting proportion according to the needs of Different Crop.
The invention has the beneficial effects as follows, coating nitrogen granular fertilizer carrier and nitrogen phosphorus k particle fertile carrier has satisfied namely that farm crop early stages has been satisfied again crop mid-term to the needs of nitrogen, phosphorus, potassium and the later stage removes to the needs of nitrogen the link of topdressing from, facilitates farming, has alleviated labor capacity.Ghost after simultaneously in coating, nutrient releases can be retained and conserved soil moisture, and can play again ventilation fertilizer conservation function, makes the soil that hardens for a long time become loose and can reject objectionable constituent in soil.The ecological organic matter that adds in shell can affect the transfer ability of pollutent (heavy metal, many cyclophanes footpath, agricultural chemicals) and the biological effectiveness of the nutritive elements such as C, N, S and P, but also is the important factor in order of Mineral Weathering, soil-forming process and microbial growth metabolism, decomposition of soil organic matter and conversion process; In film, B, Zn can regulate Crop nutrient balance, improve crop-environmental ecology relation, improve the yield and quality.The coated fertilizer particle can be controlled nutrient release amount, has improved utilization rate of fertilizer, and is economical, laborsaving, save time, upgrading synergy
