Abstract
Diammonium phosphate is a high-concentration and water-soluble fertilizer which has less solid content after being dissolved and provides nitrogen and phosphorus elements for crops, however, the long-term field trial and research results show that for crops which are fond of phosphorus and needs nitrogen, the nitrogen content of the diammonium phosphate is low and cannot meet the demands of the crops, and on the other hand, after the diammonium phosphate is applied into the soil, only 30-50% of diammonium phosphate can be absorbed and utilized by the crops, and the rest is lost in vain. At present, the farmland soil is severely polluted by heavy metals and fertilizer damage; the soil is lack of organic matters and medium trace elements in general; and the soil fertility is reduced, and the productivity is lowered. According to the ecologic slow-released diammonium phosphate and the preparation method, the ecologic slow-released diammonium phosphate is a mixture granule of two colors, namely, an enveloped nitrogen granular-fertilizer carrier and a phosphorus granular-fertilizer carrier; the demands of the crops on nitrogen and phosphorus are met; the enveloped granules prolong the release time of nutrients, the loss of the nutrients is reduced, and meanwhile the crop yield is increased and the soil is improved through the ecologic organic matters and the medium trace elements such as B and Zn added into the shell.
Description
Affiliated technical field
The present invention relates to a kind of diammonium phosphate, it is characterized in that by two kinds of granulometric composition, a kind of coated granule of a kind of not coated granule, orange and white, orange and black.Be rich in long ecological slow-releasing diammonium phosphate of many kinds of substance and nutrient-lapsed time and preparation method thereof in film
Background technology
At present, known diammonium phosphate is a kind of high density readily avaiable fertilizer soluble in water, the needs of the less applicable various farm crop of solid substance to the nitrogen phosphoric after dissolving, and make base manure, seed manure, topdress in the area that is particularly suitable for drought.But long-time field test and result of study show, need the farm crop of nitrogen for happiness phosphorus, the content of diammonium phosphate nitrogen is on the low side can't satisfy the needs of farm crop, on the other hand, after diammonium phosphate is manured into soil, the utilization absorbed by crops of 30%-50% energy is only arranged, and 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, avoid the loss of nutrient and improve soil, the invention provides a kind of ecological slow-releasing diammonium phosphate, traditional diammonium phosphate particle is canescence or the Dark grey color is single, this invention diammonium phosphate particle is double-colored particle, orange and white, orange and black.Two kinds of particles are divided into coated granule and coated granule not.The particle of coating is not phosphorus granular fertilizer carrier, the particle of coating is nitrogen granular fertilizer carrier, 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.
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 phosphorus granular fertilizer carrier in encapsulation tool, the ratio of coating nitrogen granular fertilizer carrier is 3: 1.
The invention has the beneficial effects as follows, coating nitrogen granular fertilizer carrier and phosphorus granular fertilizer carrier, namely satisfied farm crop the needs of phosphorus have been satisfied again needs to nitrogen, ghost after in coating, nutrient releases simultaneously 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.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.
