Abstract
The invention relates to an ore slow release compound fertilizer which comprises the following ingredients in parts by weight: 60 to 80 parts of coal ash, 3 to 8 parts of iron tailing ore, and 30 to 40 parts of a compound fertilizer. The invention further relates to a preparation method of the ore slow release compound fertilizer. The preparation method comprises the following steps: crushing the 60 to 80 parts of coal ash and the 3 to 8 parts of iron tailing ore into powder by a crusher, and magnetizing the powder in a magnetic field; adding the magnetized powder into water and performing stirring; granulating the 30 to 40 parts of the compound fertilizer; spraying the stirred liquid onto the compound fertilizer granules, coating the compound fertilizer granules, and drying the coated compound fertilizer granules to obtain the ore slow release compound fertilizer. The ore slow release compound fertilizer and the preparation method have the advantages that the process is simple; the production period is short; the raw materials are wide in source; the equipment requirement is low.
Description
Technical field
The present invention relates to a kind of fertilizer, particularly a kind of ore in sand form slow-release compound fertilizer and preparation method thereof.
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 to the crop of base fertilizer of composite fertilizer, because Different Crop ground regulation of fertilizer requirement needs to supplement in time instant nitrogenousfertilizer when topdressing, to meet crop alimentary needs.But long-time field test shows with result of study, 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.For happiness phosphorus, potassium, need the farm crop of nitrogen, the needs that the content of composite fertilizer's nitrogen is on the low side cannot meet farm crop also needs topdress again, i.e. expensive not only effort but also time-consuming.After being manured into soil, only have the utilization absorbed by crops of 30%-50% energy, 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; More than 50% nitrogen loss; Continuous cropping kind plant, causes soil-borne disease to increase the weight of; Soil fertility declines, and productivity declines.
Now also there is relevant design, CN102180734A as open in Chinese patent, a kind of polymer emulsion coated slow release fertilizer take nano material as carrier, nanometer soil material after treatment, proper fermentation bacterium slag after treatment and nutrient raw material are evenly mixed, then in this compound, add and be furnished with the organosilicon-modified acrylate emulsion of linking agent and mix, being prepared into a kind of surface has the polymer emulsion coated slow release fertilizer take nano material as carrier of hydrophobic film.
But above-mentioned employing acrylate is high as its difficult degraded of slow-release fertilizer dressing and cost.
Summary of the invention
In order to solve existing slow-release fertilizer, adopt acrylate as slow-release fertilizer dressing its difficult degraded and the high shortcoming of cost, the invention provides a kind of ore in sand form slow-release compound fertilizer and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ore in sand form slow-release compound fertilizer, its component, in weight fraction, comprises 60-80 part flyash, 3-8 part iron tailings ore in sand form, 30-40 part composite fertilizer.
A preparation method for ore in sand form slow-release compound fertilizer, preparation process is as follows:
(1) 60-80 part flyash and 3-8 part iron tailings ore in sand form are added and in pulverizer, be ground into Powdered and magnetize in magnetic field;
(2) the above-mentioned powder making is added to the water to stirring;
(3) by 30-40 part compound fertilizer granulating;
(4) by the liquid spraying being stirred to compound fertilizer granules and compound fertilizer granules is wrapped to oven dry make required ore in sand form slow-release compound fertilizer.
The invention has the beneficial effects as follows: technique is simple, with short production cycle, the wide equipment requirements of raw material sources is low.
