Abstract
The invention relates to a composite fertilizer, in particular to a liquid composite fertilizer which belongs to the technical field of agricultural fertilizer. The liquid composite fertilizer is prepared by using nitramine, urea, ammonium phosphate and potassium chloride as a raw material. The liquid fertilizer can be applied directly by trickle irrigation and spraying and has the advantages of high fertilizer application accuracy, high mechanical degree and low cost.
Description
Technical field
The present invention relates to a kind of composite fertilizer, be specifically related to a kind of liquid composite fertilizer, belong to agricultural fertilizer technology field.
Background technology
In farmland fertilization, the dissolving of granular chemical fertilizer need expend large quantity of moisture, and because of reasons such as lacks of water, the granular chemical fertilizer dissolution time is oversize, can influence growing of farm crop sometimes.Liquid composite fertilizer is because its various nutritive ingredients are dissolved in the water equably, make it in mechanical fertilization, bring into play the fertile unexistent superiority of solid compound, liquid fertilizer can directly be used by drip irrigation and spraying system, has fertilising accuracy height, mechanization degree height, advantage that cost is low.At present, the use of liquid fertilizer mainly concentrates on developed countries such as America and Europe with production, and the most area of China all produces and uses liquid composite fertilizer.
Summary of the invention
The objective of the invention is provides a kind of liquid composite fertilizer for overcoming above-mentioned the deficiencies in the prior art part, and liquid composite fertilizer is that raw material makes by ammonium nitrate, urea, phosphorus ammonium, Repone K.Liquid fertilizer can directly be used by drip irrigation and spraying system, has fertilising accuracy height, mechanization degree height, advantage that cost is low.
The present invention realizes with following technical scheme: a kind of liquid composite fertilizer, it is characterized in that: liquid composite fertilizer is that raw material is formed by ammonium nitrate, urea, phosphorus ammonium, Repone K, described phosphorus ammonium is monoammonium phosphate or diammonium phosphate, and described liquid composite fertilizer is by ammonium nitrate: urea: phosphorus ammonium: the Repone K weight ratio is 5: 10: 5.
A kind of method for preparing the described liquid composite fertilizer of claim 1, it is characterized in that: after above-mentioned raw materials Repone K, monoammonium phosphate and diammonium phosphate, urea and water are quantitatively mixed, fully stir by prescription, left standstill 24 hours, filter, in liquid, add complexing agent and stirring, promptly get liquid composite fertilizer.
Advantage of the present invention is: this liquid composite fertilizer prescription is reasonable, and cost of material is low, and the course of processing is simple, and liquid fertilizer can directly be used by drip irrigation and spraying system, and fertilising accuracy height, mechanization degree height, cost are low.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail:
Embodiment,
Liquid composite fertilizer is that raw material is formed by ammonium nitrate, urea, phosphorus ammonium, Repone K, and described phosphorus ammonium is monoammonium phosphate or diammonium phosphate, and described liquid composite fertilizer is by ammonium nitrate: urea: phosphorus ammonium: the Repone K weight ratio is 5: 10: 5.
A kind of method for preparing the described liquid composite fertilizer of claim 1, it is characterized in that: after above-mentioned raw materials Repone K, monoammonium phosphate and diammonium phosphate, urea and water are quantitatively mixed, fully stir by prescription, left standstill 24 hours, filter, in liquid, add complexing agent and stirring, promptly get liquid composite fertilizer.
Claims (2)
1. liquid composite fertilizer, it is characterized in that: liquid composite fertilizer is that raw material is formed by ammonium nitrate, urea, phosphorus ammonium, Repone K, described phosphorus ammonium is monoammonium phosphate or diammonium phosphate, and described liquid composite fertilizer is by ammonium nitrate: urea: phosphorus ammonium: the Repone K weight ratio is 5: 10: 5.
2. method for preparing the described liquid composite fertilizer of claim 1, it is characterized in that: after above-mentioned raw materials Repone K, monoammonium phosphate and diammonium phosphate, urea and water are quantitatively mixed, fully stir by prescription, left standstill 24 hours, filter, in liquid, add complexing agent and stirring, promptly get liquid composite fertilizer.
