Abstract

A water-soluble high-concentration multi-element fertilizer for increasing the yield of agricultural crops is prepared proportionally from potassium dihydrogen phosphate, ammonium phosphate, potassium nitrate, urea phosphate, urea, Fe, Cu, Mn, ammonium molybdate, borax and zinc sulfate.

Description

The polynary fertilizer of the complete water-soluble nitrogen phosphorus potassium of high density

Technical field:

The present invention is relevant with fertilizer, and is special relevant with the polynary fertilizer of the complete water-soluble nitrogen phosphorus potassium of high density.

Background technology:

Polynary fertilizer is a kind of compound fertilizer.Compound fertilizer is world Fertilizer industrial development direction.Global consumption has surpassed 1/3 of chemical fertilizer aggregate consumption, and China accounts for 18% of domestic and international chemical fertilizer aggregate consumption.The use of fertilizer also by the shortage that overcomes single-element in the past stand up " correct fertilising " change " balance fertilizing " that nutritive ingredient cooperates over to, compound fertilizer arises at the historic moment just in this case.Because compound fertilizer can supply crop multiple available nutrient simultaneously, the mutual promoting action between the performance nutrient, physical property is good, and minor component is few, easily stores, and is also little to the soil disease influence, is a kind of new type chemical fertilizer.GB GB1063-94 is to total nutrient (N+P ₂O ₅+ K ₂O) 〉=40% (high density); Concentration in 30%; 20% (lower concentration).Water-soluble phosphorus per-cent 〉=50% (high density); 50% (middle concentration); 40% (lower concentration).Free-water≤2.0% (high density), 2.5% (middle concentration), 5.0% (high density).

Summary of the invention:

The objective of the invention is for a kind of total nutrient (N+P is provided ₂O ₅+ K ₂O) 〉=60%, the multiple water soluble trace elements of trace 〉=0.2%, the complete water-soluble nitrogen phosphorus potassium multi-element compound fertilizer of high density applied widely.

The object of the present invention is achieved like this:

The complete water-soluble nitrogen phosphorus potassium multi-element compound fertilizer of high density of the present invention is characterized in that being made up of following component by weight percentage:

Potassium primary phosphate 10～35%,

Ammonium phosphate 0～15%,

Saltpetre 20～30%,

Ureaphil 0～15%,

Urea 10～37%,

Iron 0.05～0.1%,

Copper 0.05～0.1%,

Manganese 0.05～0.1%,

Ammonium molybdate 0～0.01%,

Borax 0.1～0.5%,

Zinc sulfate 0.1～0.5%.

The polynary multiple fertilizer of the complete water-soluble nitrogen phosphorus potassium of above-mentioned high density is made up of following component by weight percentage:

Potassium primary phosphate 31%,

Ammonium phosphate 8%,

Saltpetre 20%,

Ureaphil 15%,

Urea 25.2%,

Iron 0.1%,

Copper 0.05%,

Manganese 0.05%,

Ammonium molybdate 0.05%,

Borax 0.5%,

Zinc sulfate 0.05%.

Compare with existing compound fertilizer, the polynary fertilizer of the present invention has following advantage:

1, owing to adopted the measured saltpetre of matter, ammonium phosphate, potassium primary phosphate, Ureaphil, urea, make total high N+P of nutrient in the fertilizer ₂O ₅+ K ₂O, content 〉=60%, N12～26% wherein, P ₂O ₅12～40%, K ₂O15～40%;

2, water-insoluble≤2% can dissolve rapidly in water;

3, contain multiple water-soluble (most is the chelating attitude) trace element: trace element (TE): iron+copper+manganese+zinc+magnesium+molybdenum+boron etc. 〉=0.2%;

4, applied widely: as not only to satisfy the requirement of modern water-saving agriculture sprinkling irrigation, drip irrigation and pollution-less agriculture to fertilizer, also be applicable to simultaneously all crops such as vegetables (comprising booth vegetable), field crop, melon and fruit, flowers, tobacco leaf, tealeaves, cotton, lawn, gardens, remarkable effect of increasing production is arranged, can increase production 15～30% through test.
