Description
Technical field
The present invention relates to a kind of chemical fertilizer and production method thereof, is high-nitrogen slow released agglomeration resistant compound fertilizer and production method thereof specifically.
Technical background
Along with the continuous development of agriculture production, the traditional agriculture of highly energy-consuming, high pollution, low output will be substituted by the ecological agriculture of high yield, low consumption, high-quality and efficient Sustainable development.Desire to reach this target, it is low at first will to solve chemical fertilizer nutrient utilization ratio, the present situation that the mechanized application degree is poor, repeat random fertilising.Address this problem except that balance formula fertilising, improve the scientific level of fertilising, with regard to fertilizer self, must improve the fertilizer formulation, develop applied widely, nutrient utilization ratio height, environmental pollution degree second, can protect fertile synergic new-type fertilizer product.Slow release fertilizer is the fertilizer that the effective nutrient of chemical fertilizer is slowly discharged, from 20th century the seventies begin to occur, research and the category that uses are limited to the slowly-releasing aspect of nitrogen product substantially, also are confined to conceptual phase for compound slow release fertilizer and production method thereof.Aspect the compound slow-release nitrogen fertilizer, adopt two kinds of methods to solve the problem that the nitrogenous fertilizer dissolving is fast, utilization ratio is low usually.The one, reduce the solvability of fertilizer by the method for physics or chemistry; The 2nd, put on one deck coat to fertilizer, one deck waterproof layer is set artificially, prevent that it from directly contacting with soil and dissolving rapidly.Above-mentioned first method and difference of the present invention are bigger.The coating material that second method adopted can be divided into polymkeric substance and sulphur dressing, inert material dressing two big classes, polymkeric substance and sulphur dressing are because poorly soluble, coatings does not contain water-soluble material, cause the exudative poor of fertilizer, the rate of disengaging and the farm crop regulation of fertilizer requirement of nutrient are inconsistent, also can cause second environmental pollution sometimes, and the carrier of inert material dressing mostly is mechanical wet goods material, as improper use, also cause second environmental pollution easily.
In addition, fertilizer agglomeration, the particularly agglomeration problems of ternary compound fertilizer material have seriously restricted the development of composite fertilizer industry.
The purpose of this invention is to provide a kind of effective nutrient, non-caking high-nitrogen slow released agglomeration resistant compound fertilizer and production method thereof of evenly, slowly discharging.
Summary of the invention
For achieving the above object, the present invention adopts following technical scheme:
High-nitrogen slow released agglomeration resistant compound fertilizer of the present invention, the dressing that comprises granular fertilizer core and be wrapped in the fertilizer core outside, it is characterized in that: described fertilizer core is a ternary compound fertilizer material particle, described dressing is for including the urea of fusing and the mixed solution of agent of composite anticaking piece or compound nitrogen slow release agent at least, the agent of composite anticaking piece is by paraffin, alkylamine salt, the mixture that three kinds of materials of alkylbenzene sulfonate mix according to 55: 85: 85 ratio of weight and number, compound nitrogen slow release agent are the mixtures that is mixed according to 1: 1 ratio of weight and number by quinhydrones and Dyhard RU 100.
The ratio of weight and number of urea and the agent of composite anticaking piece is 100 in the above-mentioned mixed solution: 55-60.
Also contain compound nitrogen slow release agent in the above-mentioned mixed solution, wherein the ratio of weight and number of urea, compound nitrogen slow release agent is 100: 20-22.
The production method of high-nitrogen slow released agglomeration resistant compound fertilizer of the present invention, it is characterized in that: ternary compound fertilizer material particulate temperature is controlled at 35 ℃-50 ℃, be 600 with urea, the agent of composite anticaking piece and compound nitrogen slow release agent according to ratio of weight and number simultaneously: the ratio of 225-230: 18-20 is heated to fusing and mixes, and adopts the injection packaging technique that it is ejected into ternary compound fertilizer material particulate surface; The agent of composite anticaking piece is the mixture that is mixed according to 55: 85: 85 ratio of weight and number by paraffin, alkylamine salt, three kinds of materials of alkylbenzene sulfonate, and compound nitrogen slow release agent is the mixture that is mixed according to 1: 1 ratio of weight and number by quinhydrones and Dyhard RU 100.
In spraying the dressing process, be compound nitrogen slow release agent and urea 15-20 according to ratio of weight and number at first: 100 mixed also is heated to and is melted into composite slow release agent one urea mixed solution, be urea and the agent of composite anticaking piece 100 according to ratio of weight and number simultaneously: the mixed of 55-60 also is heated to and is melted into urea-composite anticaking piece agent mixed solution, be 18-20 with composite slow release agent-urea mixed solution and urea-composite anticaking piece agent mixed solution according to ratio of weight and number then: 50 ratio is delivered to the nozzle of injector simultaneously, sprays to be wrapped in ternary compound fertilizer material particulate outside surface.
The present invention is a carrier with the urea liquid of fusing, paraffin, alkylamine salt and alkylbenzene sulfonate are anti-hard caking agent, taken into full account the urea of fusing and the mutual solubility of composite anticaking piece agent, and mixed solution is adsorbed on the surface of fertiliser granulates easily after spraying, reaches the purpose of anti-caking.Simultaneously,, changed the quick-acting of Drug coating carrier-urea effectively, overcome nitrogenous fertilizer because of the problem of environmental pollution nitrated, that leaching loss causes owing to the use of composite slow release agent.
