Description

A kind of full-service fluid calcareous fertilisers and production method thereof

One, technical field:

The present invention relates to a kind of technical field of fertilizers, specifically relate to a kind of full-service fluid calcareous fertilisers and production method thereof.

Two, background technology:

Calcium is combined with the pectin substance of mesogloea and is formed calcium pectinate in cell walls, and when calcium deficiency, in cell walls, the formation of calcium pectinate is obstructed, and cell walls can not form.Calcium is the activator of many enzymes in plant materials, therefore calcium has promoter action to the many metabolic processes in plant materials, and calcium also has the effect of stabilate film and adjusting medium physiological equilibrium simultaneously, and the transportation of calcium deficiency plant nutrient substance is obstructed, there is the bitter pit of apple, the blossom-end rot of tomato etc.In recent years because the calcium loss in soils in south china and soils of north China happen occasionally to the plant calcium deficiency problem that fixedly causes of calcium, and traditional calcareous fertilisers are owing to easily causing the reduction of calcareous fertilisers utilization ratio with the negatively charged ion formation indissoluble type compound of soil and plant materials.

The using method of liquid calcium fertilizer is mainly and sprays nitrocalcite, calcium chloride and chelating state calcareous fertilisers at present, the wherein more difficult absorption of inorganic calcareous fertilisers crop, and after absorbing, movability is poor; In fertilizer of chelated calcium, conventionally sequestrant used is the glycitols compounds such as simple ethylenediamine tetraacetic acid (EDTA) (EDTA), multiple amino acids, glucose, stability constant is low, in plant materials, still can there is hydrolysis and inactivation in calcium ion, secondly because calcium and phosphorus and various trace elements all can form infusible precipitate, so it is extremely rare to contain the calcareous fertilisers of high content nitrogen, phosphorus, potassium, trace element in commercially available calcareous fertilisers simultaneously, and calcareous fertilisers can not be simultaneously and common phosphorous, micro-liquid fertilizer mixture use, caused the inconvenience in vast farmers production.

Three, summary of the invention:

The present invention, in order to solve the weak point in above-mentioned background technology, provides a kind of full-service fluid calcareous fertilisers and production method thereof, and this seed manure material nutrient is comprehensive, fertilizer efficiency remarkable, stable uniform, of many uses.

For achieving the above object, the technical solution used in the present invention is: a kind of full-service fluid calcareous fertilisers, is characterized in that: be made up of following weight part raw material: 1 ~ 5 part of disodium ethylene diamine tetraacetate, 2 ~ 10 parts, potash fertilizer, 30 ~ 85 parts, nitrocalcite, phosphatase 11 ~ 10 part, 1 ~ 10 part of zinc nitrate, 0.1 ~ 1 part of boric acid, 1 ~ 10 part of lactic acid, 2 ~ 10 parts of Methionins, 0.1 ~ 0.3 part of copper fertilizer, 2 ~ 55 parts of softening waters.

Described potash fertilizer is one or more among Repone K, saltpetre.

Described Methionin is containing the white soluble powder of 1B >=65% or the high sterling of white solubility hydrochloric acid Methionin of Methionin >=98%.

Described copper fertilizer is one or more among cupric nitrate, cupric ethylene diamine tetraacetate disodium salt.

A kind of production method of full-service fluid calcareous fertilisers comprises the following steps:

The first step: add softening water, disodium ethylene diamine tetraacetate, potash fertilizer, nitrocalcite, zinc nitrate, boric acid, copper fertilizer in finished product preparing tank, temperature remains on 60～70 ℃, complex reaction 1～1.5 hour;

Second step: Methionin, lactic acid, phosphoric acid are added in finished product preparing tank successively, and temperature remains on 50～55 ℃, the reaction of sizing mixing is extremely dissolved for 0.5～1 hour completely;

The 3rd step: aforesaid liquid continues to be stirred to normal temperature, obtains the full-service fluid calcareous fertilisers of blueness, stable uniform.

Compared with prior art, the present invention has advantage and effect are as follows:

(1) disodium ethylene diamine tetraacetate in product of the present invention, Methionin, lactic acid are efficient calcium sequestrant, and stronger with respect to the common sequestrant such as amino acid, glucose performance, stability is higher, and the absorption rate of calcium strengthens greatly;

(2) in product of the present invention, contain high concentration N, phosphorus, potassium and trace element, transparent and homogeneous, good stability, overcome traditional calcareous fertilisers can not with the present situation of high concentration phosphate fertilizer and micro-mixture, can in replenishing the calcium, supplement crop various nutrient elements, achieve many things at one stroke, saving of work and time.

(3) the key technical indexes of the present invention:

Ca≥120?g/L

N+P ₂O ₅+K ₂O≥100g/L

Zn+B≥2g/L

PH value (250 times of diluents): 3.0 ~ 8.0
