Abstract
Slow effect on packaged fertilizer is to be core with the water soluble fertilizer, is sustained release dosage with vegetables oil, animal oil or its greasy filth or its modifier, under the effect of natural and inorganic adhesive, and a kind of fertilizer that makes with parcel such as fused(calcium magnesium)phosphate or thomas phosphate.Plant nutrient ingredient such as potash fertilizer, trace element can be used as the wrapping inner layer of core.
Slow effect on packaged fertilizer is the inorganic of a kind of multi-nutrient a---organic composite fertilizer, can provide an amount of organic matter to soil, helps preservation of fertility.Sustained release dosage has the rate of release of slowing down soluble component, cheap and to characteristics such as soil is pollution-free.
Description
The invention belongs to slow effect on packaged fertilizer.
The slow-release fertilizer that is occurred in the world at present can be divided into this build and Envelope type two classes basically.The former is the slow-release fertilizer of directly making by chemical synthesis, as urinate formaldehyde fertilizer, IBDU and polyacrylamide etc., the latter is to be core with water-soluble granular fertilizer, and the outside coats various inorganicss (as sulphur etc.) or organic compound (as various natural or synthetic resins etc.).
The slow effect of this build slow-release fertilizer is relatively good, but costs an arm and a leg.Coated fertilizer is many as core, for example to wrap Thio Urea with single fertilizer (mainly being nitrogenous fertilizer).In recent years, for adapting to the requirement of crop, occurred again the coated fertilizer that is core with granular NPK compound manure to various nutrient elements.This fertilizer mostly with sulphur, paraffin and various petroleum resin or synthetic resins (for example polyethylene, polypropylene, polyvinyl chloride, acrylate and urethane etc.) as coating layer.Because costing an arm and a leg of most of coating materials causes fertilizer to bring a high price, and limited using of field crop, be used for garden crop at present more.With regard to the coated fertilizer that occurs at present, most of coated fertilizers are not the nutritive elements of plant, do not have the effect of improving the soil yet.In addition, this build slow-release fertilizer and coated fertilizer generally all can cause soil pollution in various degree.
The Wrapped fertilizer of Chinese patent CN851010083 is to be core with ammonium nitrate, urea, phosphorus ammonium or ammonium chloride, is binding agent with nitrogen phosphorus mud, with fused(calcium magnesium)phosphate, precipitated superphosphate or bone meal said core is wrapped up, and makes Wrapped fertilizer.Compare with general mixed fertilizer, Wrapped fertilizer has uniform particles, is difficult for moisture absorption and caking, is convenient to store and mechanized application, and utilization rate of fertilizer is than advantages such as height, compare with coated fertilizer, the core of Wrapped fertilizer is a water-soluble granular fertilizer, and the binding agent and the integument itself that adopt also are the main nutrient elements of plant, are a kind of polyelement composite fertilizers therefore.
But aspect the water-soluble nutritive ingredient of slow release, Wrapped fertilizer is then not ideal.Though the fused(calcium magnesium)phosphate itself as integument is water-fast, can observe the powdered calcium magnesium-phosphorus fertilizer under electron microscope is sheet structure, and many holes that differ in size (0.2-0.5 μ m) are arranged on its surface.When using the powdered calcium magnesium-phosphorus fertilizer, between particle, still there are many holes as integument.Because the existence of these holes, crackle and hole, can not hinder the infiltration of water molecules effectively, therefore, water soluble fertilizer in the core still can be released in the soil with speed faster, once in the laboratory Wrapped fertilizer had been carried out the immersion dissolution test, promptly in the beaker that is filled with water, put into Wrapped fertilizer, take out through the regular hour and observe whether still existence of core.Through experiment, straight fertilizers such as ammonium nitrate, urea are i.e. all dissolvings through 1-2 minute, and urea, ammonium nitrate in the above-mentioned Wrapped fertilizer core, its soaking time 1.5-2 hour only.
The dissolution rate that the objective of the invention is to make a kind of soluble component slowly, contain the inorganic-organic composite type slow effect on packaged fertilizer of various nutrient elements.This fertilizer can provide an amount of organic matter to soil, helps preservation of fertility, and can control the release rate of water soluble fertilizer according to the needs of different areas, Different Crop.
The present invention is to be core with the water soluble fertilizer, with the vegetables oil, animal oil or its greasy filth that plant are had certain trophism or its mixture or its modifier as sustained release dosage, under the effect of natural and inorganic adhesive, with fused(calcium magnesium)phosphate or thomas phosphate said core is wrapped up, make slow effect on packaged fertilizer.Nutritive ingredient such as potash fertilizer, trace element can be used as the wrapping inner layer of core.Slow effect on packaged fertilizer be a kind of inorganic-organic composite type fertilizer.
The core of slow effect on packaged fertilizer accounts for the 20-50% of fertilizer gross weight, and integument accounts for the 40-77% of fertilizer gross weight, can regulate the NPK proportioning according to the needs of crop.Sustained release dosage accounts for the 3-10% of fertilizer gross weight, regulates the slow effect on packaged fertilizer that sustained release dosage consumption and integument thickness just can make different rates of release.When the sustained release dosage consumption was 3-10%, the soaking time that core is kept perfectly was 15-30 days.In the soil that is embedded in certain humidity, after three months, observe, still have part particulate core to exist.The particle mean compressive strength of slow effect on packaged fertilizer is 10-30N.
Sustained release dosage of the present invention is: (1) each vegetable oil, as oleum gossypii seminis, rape seed oil, sesame oil, peanut oil and tung oil etc.; (2) greasy filth of above-mentioned each vegetable oil or residual oil; (3) various animal oil are as lard and butter etc.; (4) mixture of above-mentioned vegetables oil, animal oil or greasy filth; (5) vegetables oil after the modification, animal oil or its greasy filth.Sustained release dosage itself has certain nutritive ingredient, as the about 8-12% of NPK content of plant greasy filth.
The properties-correcting agent of sustained release dosage has starch and Mierocrystalline cellulose and the various organic waste materials etc. after vegetable wax, beeswax, butyl oleate, aluminium oleate, casein food grade, the modification.
Binding agent used in the present invention is natural glue and inorganic adhesive, rosin resin adhesive for example, and phosphoric acid salt tackiness agent etc., binder dosage is about the 5-15% of fertilizer gross weight.
The manufacture method of slow effect on packaged fertilizer: (1) is placing a certain amount of potash fertilizer (can add trace element as required) in the packing machine earlier continuously, other takes by weighing water soluble fertilizers such as the urea of some amount or ammonium nitrate, mix earlier with top said sustained release dosage, to particle surface all wetting till, pour into then in the continuous packing machine of continuous rotation; (2) spray into above-mentioned sustained release dosage equably by nozzle, and be sprinkled into pulverous fused(calcium magnesium)phosphate or thomas phosphate etc.; (3) alternately spray into H

4And Al(OH)
3Mixing solutions, and be sprinkled into fused(calcium magnesium)phosphate, until obtaining the granulated fertilizer that particle diameter is 2-4mm.After the slow effect on packaged fertilizer drying that makes, pack and get product.
