Abstract

The present invention provides a making method for a mixed complex fertilizer. The fertilizer is prepared by mixing the granular raw materials of urea, diammonium phosphate and ammonium nitrate with the fourth granular raw material formed by granulation, and processing the mixture by magnetic treatment. The product contains a plurality of nutrient elements, such as N, P, K, Ca, Mg, S, Zn, Fe, Re, etc., and the total content of N, P2O5, K2O is no less than 40%; the product also contains a water-keep agent, insecticide, a germicide, a magnetic carrier, etc., so that the fertilizer of the present invention has the functions of resisting drought, preservating soil moisture, improving the soil, raising the utilization rate of nutrients and preventing and treating plant diseases and insect pests.

Description

A kind of making method of mixed compound fertilizer

The invention provides the making method of a kind of fertilizer, particularly a kind of mixed compound fertilizer.

The development trend of modern fertilizer industry is the compound manure of Development and Production high density.Mixed compound fertilizer is easy to adjust because of its composition, thereby can satisfy the needs of Different Crop and soil preferably and come into one's own.Existing mixed compound fertilizer function ratio is less, does not have the such physical factor of magnetic action to fertilizer efficiency and the contribution of improving the soil, and does not also have pesticide-germicide function and water retaining function.The invention provides a kind of making method of novel mixed compound fertilizer, this novel mixed compound fertilizer nutrient concentration height, the nutritive element that contains are many, have the function of magnetic, water retention property and prevention and elimination of disease and pests simultaneously.

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

Used raw material comprises fertilizer material, magnetic carrier, water-holding agent, sterilant, sterilant, synergistic agent.The composition scope of fertilizer material contains the ammonium nitrate 0～30% of N＞34% for containing the urea 10～45% of N＞46%, contains N＞18%, contains P ₂O ₅＞46% diammonium phosphate 10～50% contains K ₂The Repone K 10～45% of O＞59% contains K ₂The vitriolate of tartar 0～30% of O＞49% contains P ₂O ₅＞14% calcium superphosphate 4～15% contains P ₂O ₅＞14% fused(calcium magnesium)phosphate 1～10% contains Re ₂O ₃＞25% mishmetal complex compound 0.05～0.4% contains the zinc sulfate 0.1～1.2% of Zn＞23%; Magnetic carrier is for containing the Iron and Steel Production by product ion dust mud contaning 2～10% of Fe＞40%; Water-holding agent is an acrylate hydroscopic high-molecular resin 0.05～0.8%; Sterilant is 15% aldicarb 0.05～0.3%; Sterilant is 70% thiophanate_methyl 0.05～0.3%; Synergistic agent is an Asprin 0.005～0.03%.Nitrogen, phosphorus, the pure calculating of potassium N, P ₂O ₅, K ₂The O summation is not less than 40%.

Take by weighing raw material by prescription; except that Granular Urea, diammonium phosphate, ammonium nitrate; all the other raw materials are basic identical to diameter and above-mentioned three kinds of granular feedstock mean diameters at rotary drum or the balling-up of disc type tablets press behind pulverizing, mixing; mix with Granular Urea, diammonium phosphate, ammonium nitrate after drying, cooling, the screening; be the magnetic treatment 0.5～5 second of 0.5～0.8T again through magnetic induction density; make product have residual magnetic flux density Br=(0.05～0.10) mT, coercivity H=(3～8) KA/m.This fertilizer is also having the function of soil moisture conservation of improving the soil, economize on water and prevention and elimination of disease and pests than equilibrated in crop supply nutrition, and is particularly suitable to the lack of water arid area.

Embodiment: make 1 ton of mixed compound fertilizer, select ammonium nitrate 10Kg, Repone K 200Kg, vitriolate of tartar 70Kg, calcium superphosphate 40Kg, fused(calcium magnesium)phosphate 10Kg, ion dust mud contaning 33Kg, zinc sulfate 4.5Kg, mishmetal complex compound 0.5Kg, acrylate water-retaining agent 1Kg, the aldicarb 0.5Kg of granular diammonium phosphate 300Kg, Φ 2～Φ 4mm of Granular Urea 330Kg, the Φ 2～Φ 4mm of Φ 2～Φ 4mm for use, methyl sulfur bacterium bactericide 0.4Kg, synergistic agent Asprin 0.1Kg.This fertilizer (N+P ₂O ₅+ K ₂O) concentration is 50%.

Remove Granular Urea; outside granular diammonium phosphate and the ammonium nitrate; remaining material is pulverized in hammer crusher and mixing in conical mixer; then through the granulating disc granulation; treat the basic and urea of particle dia; when granular diammonium phosphate and ammonium nitrate granule are consistent; can carry out drying; cooling and screening; the material of the particle diameter Φ 2～Φ 4mm that obtains through screening is sent in the conical mixer with Granular Urea and diammonium phosphate and ammonium nitrate and was mixed 3 minutes; and then be that the magnetreater of 0.6T is handled and made it to have Br=0.1mT, Hc=6.2KA/m 2 seconds through magnetic induction density.With this fertilizer and N, P ₂O ₅, K ₂O respectively is that 15% pure amounts such as composite fertilizer are applied to No. 3 sugarcanes of Jiangxi sugarcane, and soil property is a silty loam, trench digging fertilising, 80 kilograms/mu of amounts of application.Use this fertilizer compared with the control, sugarcane germination rate height in early stage, disease resistance is stronger, middle and later periods drought resisting, resistant to lodging, output reaches 7.15 tons of per mu yields, volume increase 21%.Sugar degree reaches 16.5%, increases by 13%.
