Abstract

The invention relates to a nitrogen, phosphorus and potassium compound fertilizer, which is prepared from the following raw materials in percentage by weight: 40% of urea, 15% of monoammonium phosphate, 10% of potassium chloride, 30% of ammonium chloride and 5% of ammonium bicarbonate. The nitrogen, phosphorus and potassium compound fertilizer is reasonable in preparation, and is very easily dissolved into water; no residue exists in soil; the property of the soil is improved; sufficient nitrogen, phosphorus and potassium elements can be timely supplied to the soil; normal growth of crops is ensured; the resistance of a plant is increased; and the crop yield and the crop quality are improved.

Description

A kind of nitrogen-phosphorus-potassium compound fertilizer

Technical field

The present invention relates to a kind of composite fertilizer, is especially a kind of nitrogen-phosphorus-potassium compound fertilizer.

Background technology

Among various nutritive element, nitrogen, phosphorus, three kinds, potassium be plant requirement and results time the amount of taking away more nutritive element, and the quantity that they return to soil by the form of stubble and root is few, and often need to supplement these nutrients in the mode of applying fertilizer, therefore a kind of compound nitrogen phosphate fertilizer is developed, use with the n-p-k element run off in supply soil, there is good meaning.

Summary of the invention

In order to solve the problem, the object of the present invention is to provide a kind of nitrogen-phosphorus-potassium compound fertilizer, to reach the n-p-k element content in supply soil, make the object that content keeps stable.

A kind of nitrogen-phosphorus-potassium compound fertilizer of the present invention is formulated by following ratio of weight and number by urea, monoammonium phosphate, Repone K, ammonium chloride and bicarbonate of ammonia: urea 40%, monoammonium phosphate 15%, Repone K 10%, ammonium chloride 30% and bicarbonate of ammonia 5%.

Its preparation method is: by the amount of urea 40%, monoammonium phosphate 15%, Repone K 10%, ammonium chloride 30% and bicarbonate of ammonia 5%; take each component materials of fertilizer respectively; pulverize after their Homogeneous phase mixing again; sending into after high tower granulator carries out sprinkling granulation becomes bag to pack automatically, i.e. obtained a kind of nitrogen-phosphorus-potassium compound fertilizer finished product.

Urea is a kind of high density nitrogenous fertilizer, belongs to neutral readily avaiable fertilizer, not residual any objectionable impurities in soil, long-term application does not have detrimentally affect, and urea is organic nitrogenous fertilizer, the urase effect in soil, after being hydrolyzed into volatile salt or bicarbonate of ammonia, can effective utilization absorbed by crops.

It is optimum that monoammonium phosphate is used during plant growth as fertilizer, and monoammonium phosphate is in acid in soil, and in acid soil, it is better than general calcium, ammonium sulfate, also superior than other fertilizer in alkaline soils.

Repone K is being agriculturally a kind of potash fertilizer, and its fertilizer efficiency is fast, is directly applied to farmland, and Neng Shi soil lower floor moisture rises, and has the effect of drought resisting.

Ammonium chloride is a kind of quick-acting nitrogen chemical fertilizer, and nitrogen content is 24% ~ 25%, and soluble in water, water absorbability is larger than ammonium sulfate, and easy deliquescence is physiological acidic fertilizer, is applicable to the crops such as corn, wheat, paddy rice, Chinese sorghum, vegetables, crudefiber crop.The fibre crops such as flax, hemp are used the better effects if of ammonium chloride, especially has fortifying fibre toughness and pulling force to cotton crudefiber crop and improve effect of quality, because chlorine has the effect of fortifying fibre toughness and pulling force.

Bicarbonate of ammonia, also known as carbon ammonium, be a kind of carbonate, nitrogenous about 17.7%, can be used as nitrogenous fertilizer, disappear because it can be analyzed to NH3, CO2 and H2O tri-kinds of gases, thus fertile also known as gas, and bicarbonate of ammonia is without (sulphur) acid group nitrogenous fertilizer, its three components are all the nutrients of crop, not containing harmful intermediate product and final degradation production, long-term application does not affect soil property, is one of safest nitrogen fertilizers.

The invention has the beneficial effects as follows: a kind of nitrogen-phosphorus-potassium compound fertilizer, preparation is rationally, very easily water-soluble, noresidue in soil, improves soil property, can be the sufficient n-p-k element of the timely supply of soil, ensure crop normal growth, make plant increase resistance and improve crop yield and crop quality.

Embodiment

Below in conjunction with embodiment, the invention will be further described.

Embodiment 1

A kind of raw material of nitrogen-phosphorus-potassium compound fertilizer is:

Urea 400kg, monoammonium phosphate 150kg, Repone K 100kg, ammonium chloride 300kg and bicarbonate of ammonia 50kg.

Urea nitrogen content is about 46%, and monoammonium phosphate is 55% containing P2O5 amount, and Repone K potassium content is 57%, and ammonium chloride nitrogen content is 25%, and bicarbonate of ammonia nitrogen content is 17%.

Take each material by above-mentioned each composition weight respectively, then pulverize after their Homogeneous phase mixing, send into after high tower granulator carries out sprinkling granulation and automatically become bag to pack, be i.e. obtained a kind of nitrogen-phosphorus-potassium compound fertilizer finished product.

Embodiment 2

A kind of nitrogen-phosphorus-potassium compound fertilizer got prepared by appropriate embodiment 1 is dissolved in water, be prepared into the N P and K Water soluble fertilizer that effective constituent is 45% ~ 50%, according to plant growth demand, water in crop root or spray in blade face, because this fertilizer solvability is good, easily absorbed by crops.

Measure through simultaneous test, the nitrogen-phosphorus-potassium compound fertilizer of the present invention's configuration is compared with Common compound fertilizer, and fertilizer efficiency exceeds 2-3 doubly, and crop yield improves 5-7 doubly, and fruit quality is improved.

Claims
