Abstract

A physicochemical fertilizer is a coated one with N fertilizer as core, and contains N,P and K (more than 40%), the Ca, Mg and S and the trace elements, as well as photonutrients, magnetic carrier, soil-improving agent and fungicide. It serves to improve soil, promote photosynthesis, accelerate the dissolving and absorption of nutrients, and increase the utilization rate of high-concentration chemical fertilizer.

Description

A kind of physical chemical fertilizer

The invention provides a kind of fertilizer, particularly a kind of physical chemical fertilizer.

The high fertilizer of nutrient density owing to have is convenient to the advantage of storing, transporting and using, and become the development trend of chemical fertilizer industry, but the contained nutrient kind of existing high-concentration fertilizer is less, function singleness, and utilization ratio is lower.The purpose of this invention is to provide a kind of physical chemical fertilizer, it can obviously improve high-concentration fertilizer utilization ratio, the function that has prevention and elimination of disease and pests simultaneously, improves crop quality, improves the soil.

The objective of the invention is to realize by following technical measures.

Used raw material comprises that a large amount of, middle amount and trace element fertilizer raw material and soil improvement agent, light help nutrition agent, magnetic carrier raw material and weedicide, sterilant.Chemical fertilizer raw material consists of the urea 5～40% that contains N 〉=46%, contains the ammonium nitrate 0～15% of N 〉=34%, contains the ammonium sulfate 5～10% of N 〉=20%, contains N 〉=11%, contains P ₂O ₅〉=52% monoammonium phosphate 5～25% contains P ₂O ₅〉=12% calcium superphosphate 8～15% contains P ₂O ₅〉=12% fused(calcium magnesium)phosphate 3～10% contains K ₂The Repone K 5～20% of O 〉=60% contains K ₂The vitriolate of tartar 0～35% of O 〉=49% contains the zinc sulfate 0.5～1.0% of Zn 〉=23%, contains the borax 0.1～0.5% of B 〉=11%, contains the copper sulfate 0.1～0.2% of Cu 〉=25%, contains the nitric acid light rare earths mixture 0.1～0.3% of ReO 〉=30%; It is that 30～80% Bensulfuron-methyl wettable powder 0.1～0.2% and concentration are 65% sodium pentachlorophenate pulvis 0.1～0.2% that weedicide consists of concentration; Soil improvement agent is for containing the Attapulgite stone flour 1.0～2.0% of zeopan 〉=20%, granularity＜0.15mm; It is the light rare earths complex compound 0.1～0.2% of content 70% that light helps nutrition agent; Magnetic carrier is that residual magnetic flux density Br 〉=0.4T, coercivity H 〉=150kA/m, granularity＜0.05mm, composition are (SrO) _0.95(CuO) _0.056Fe ₂O ₃Strontium ferrites powder 0.2～0.4%, Br 〉=0.6T, Hc 〉=410kA/m, granularity＜0.05mm, composition are CeCo _3.8Fe _0.5Cu _0.9Magnetic material powder 0.1～0.2% and contain Fe 〉=20%, contain Ti 〉=5%, the ilmenite powder 2～5% of granularity＜0.1mm, this a kind of magnetic carrier in back provides required trace elements iron of crop and titanium simultaneously.Various raw materials are solid-state, and wherein sodium pentachlorophenate has soil sterilization concurrently and suppresses the nitrated function of nitrogenous fertilizer, and copper sulfate has the soil sterilization function concurrently, and the Attapulgite stone flour has the adhesive for granulating effect concurrently.

Raw material by the prescription weighing; wherein the earlier independent premix of calcium superphosphate and ammonium sulfate is 3～4 hours; and then mix with other various raw materials; be broken into through chain chip pulverizer and contain the small particle urea (powder of granularity＜2mm); granulation formation is the cladded type granule of core basically with the urea granules in the staged granulating disc; drying, cooled granulated fertilizer were handled through 0.01～0.05 second in magnetic induction is the pulsed magnetic field of 2～3T, detected through vibrating sample magnetometer to have Br=(1.0～1.5) mT, Hc=(50～80) kA/m.

This fertilizer is owing to contain various nutrient elements, and can produce soil and biomagnetism effect by coating and add nitrification inhibitor and reduce loss of nitrogen fertilizer, having in addition after remanent magnetism is used, and helps the dissolving and the absorption of nutrient, thereby improved utilization rate of fertilizer.The wavelength that light helps nutrition agent to pass through part change irradiation sunlight increases the crop photosynthesis effect.

Embodiment: make 1 ton of physical chemical fertilizer, with urea 310kg, ammonium nitrate 15kg, ammonium sulfate 70kg, monoammonium phosphate 200kg, calcium superphosphate 120kg, fused(calcium magnesium)phosphate 40kg, Repone K 180kg, zinc sulfate 8kg, borax 3kg, copper sulfate 1kg, nitric acid light rare earths mixture 1kg, concentration is that 50% Bensulfuron-methyl 1kg, sodium pentachlorophenate 1kg, light help nutrition agent 1kg, Attapulgite stone flour 20kg, ilmenite powder 24kg, strontium ferrites powder 4kg, cerium ferro-cobalt copper magnetic material powder 1kg, and nitrogen, phosphorus, the pure total amount of potassium are 41% in the batching.

At first ammonium sulfate and calcium superphosphate are mixed; after ammonium processing in 4 hours again with all the other raw material blendings; the dish diameter is 2.8 meters outside the material that chain chip pulverizer is handled is sent to; granulation in 2.0 meters staged granulating discs of inner disc diameter; control material moisture 10%; form more than 80% with urea is that the granular fertilizer of core is through 15 minutes dryings of rotary dryer; 170 ℃ of its feeding temperatures; 60 ℃ of drop temperatures; it is to carry out 0.01 second treatment time in magnetic induction is the pulsed magnetic field of 2T that magnetization is handled.After such processing, has Br=1.3mT, Hc=70kA/m.With this fertilizer and nitrogen, phosphorus, potassium respectively is that composite fertilizer's equivalent of 15% is used for the fertilising of summer corn trench digging, corn variety tucks in red 19, soil property is a sandy loam, 50 kilograms/mu of rates of fertilizer application, the result uses the plot of physical chemical fertilizer, and plant growing way stalwartness does not have weeds substantially, reach per mu yield 780Kg volume increase 18%, starch content increases by 9% simultaneously.
