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 forms calcium pectinate in cell walls, and during calcium deficiency, in cell walls, the formation of calcium pectinate is obstructed, and cell walls can not be formed.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 stabilate film and regulates the effect of medium physiological equilibrium simultaneously, and the transport of calcium deficiency plant nutrient substance is obstructed, there is the bitter pit of apple, the blossom-end rot etc. of tomato.Due to the calcium loss in soils in south china and soils of north China, the plant calcium deficiency problem that fixedly causes to calcium happens occasionally in recent years, and traditional calcareous fertilisers cause the reduction of calcareous fertilisers utilization ratio because easy and soil and plant materials negatively charged ion forms indissoluble type compound.

The using method of current liquid calcium fertilizer is mainly and sprays nitrocalcite, calcium chloride and Chelating state calcareous fertilisers, the wherein more difficult absorption of inorganic calcareous fertilisers crop, and after absorbing, movability is poor; Sequestrant usually used in fertilizer of chelated calcium is the simple glycitols compound such as ethylenediamine tetraacetic acid (EDTA) (EDTA), multiple amino acids, glucose, stability constant is low, calcium ion still can occur to be hydrolyzed and inactivation in plant materials, secondly because calcium and phosphorus and various trace elements all can form infusible precipitate, so the calcareous fertilisers simultaneously containing high content nitrogen, phosphorus, potassium, trace element in commercially available calcareous fertilisers are extremely rare, and calcareous fertilisers can not simultaneously and common phosphorous, micro-liquid fertilizer mixture use, cause 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, this kind of Fertilizer nutrient is comprehensive, fertilizer efficiency significantly, 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 raw material: disodium ethylene diamine tetraacetate 1 ~ 5 part, 2 ~ 10 parts, potash fertilizer, 30 ~ 85 parts, nitrocalcite, phosphatase 11 ~ 10 part, zinc nitrate 1 ~ 10 part, boric acid 0.1 ~ 1 part, lactic acid 1 ~ 10 part, Methionin 2 ~ 10 parts, copper fertilizer 0.1 ~ 0.3 part, softening water 2 ~ 55 parts.

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

Described Methionin is containing the white soluble powder of 1B >=65% or the white solubility lysine hydrochloride high sterling 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 DEG C, complex reaction 1 ~ 1.5 hour;

Second step: Methionin, lactic acid, phosphoric acid are added successively in finished product preparing tank, temperature remains on 50 ~ 55 DEG C, reaction 0.5 ~ 1 of sizing mixing is little of dissolving completely;

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

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

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

(2) high concentration N, phosphorus, potassium and trace element is contained in product of the present invention, transparent and homogeneous, good stability, overcome traditional calcareous fertilisers can not with the present situation of high concentration phosphate fertilizer and micro-mixture, crop various nutrient elements can be supplemented while replenishing the calcium, 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
