Abstract
The invention discloses a high-concentration drip irrigation compound fertilizer, which is characterized in that based on the preparation of the traditional 15-15-15 formula compound fertilizer, the dosages of diammonium phosphate or monoammonium phosphate in the material formula are reduced, while a corresponding amount of polyphosphate compounds is added; the raw materials are put into a reactor to prepare the high-concentration drip irrigation compound fertilizer through granulation. The invention provides rich nitrogen, phosphorus and potassium elements needed by the crops and can effectively make use of the calcium ions and the magnesium ions in the polyphosphate and water for chelation and complexing, so as to prevent the calcium ions and the magnesium ions combining with carbonate radicals, sulfate radicals and silicic acid radicals and prevent the formation of fouling in the water so as to ensure that the drip irrigation equipment is free from fouling and can work safely and normally.
Description
Technical field
The present invention relates to a kind of composite fertilizer, be specifically related to a kind of high concentration compound fertilizer for drip irrigation.
Background technology
Drip irrigation technique comes from Israel, it is economized on water efficiently, saving fertile ability is known by common people, drip irrigation technique is mainly used in the drought and water shortage area, these geographic main drip-irrigation waters are the well water in the tractor-ploughing well, and the calcium ion in most of underground water, magnesium ion content is generally all higher, be that phreatic water quality is harder, if life-time service, pipeline in the drip irrigation facility and drip can be because the irradiations of sunlight, water spontaneous evaporation incessantly in the pipeline, calcium ion in the water, magnesium ion is enrichment method and form fouling precipitation gradually, stop up dropper, drip, and then have influence on the works better of drip irrigation pipe, even facility is scrapped.
Growth needs according to Different Crop, traditional composite fertilizer roughly is divided into potassium sulfate compound fertilizer and (is mainly used in melon and fruit, tobacco etc.), potassium chloride type composite fertilizer (is mainly used in the melon dish, soybean, paddy rice, peanut etc.), saltpetre type composite fertilizer (being mainly used in tobacco etc.), other effective nutriment in a fertilizer nitrogen and phosphorus are mainly by monoammonium phosphate, diammonium phosphate, urea, the liquid urea, ammonium nitrate, ammonium chloride, ammonium sulfate, bicarbonate of ammonia etc. are nitrogenous, phosphorus, the material of potassium element carries out composite, make conventional composite fertilizer through granulation again again, this class composite fertilizer all has the characteristics of good water solubility, when applying fertilizer in non-drip irrigation mode, nutritional status to crop has fabulous improvement, for promoter action is played in the production of crop, but the existing conventional composite fertilizer of employing can not solve the fouling blockage problem in the fertigation process, can quicken the fouling of drip irrigation facility sometimes on the contrary and stop up.
The method that prevents at present calcium ion, the fouling of magnesium ion precipitation in the drip irrigation technique has multiple, and as by regulating the potential of hydrogen of pH value with control water, the pH value that makes water in the drip irrigation is slightly acidic between 6-6.5; Plant with composite fertilizer or certain single fertilizer that the chemical fertilizer of being with acidic component is re-dubbed; Directly in water, add dilute sulphuric acid or hydrochloric acid adjusting pH value, or the like.But can damage to soil if life-time service sour water is irrigated, form the hardening soil.
Summary of the invention
The objective of the invention is provides a kind of high concentration compound fertilizer for drip irrigation at the deficiencies in the prior art, it is outside providing the needed nitrogen of farm crop, phosphorus, potassium composition, can be effectively with water in calcium ion, magnesium ion carry out chelating and complexing, thereby stop calcium ion, magnesium ion to combine, the formation of fouling in the anti-sealing with carbonate, sulfate radical, silicate etc.
The technology used in the present invention principle is to utilize polyphosphate and organic phosphoric acid ammonium salt to carry out chelating and complexing with calcium ion, magnesium ion well, thereby stop calcium ion, magnesium ion to combine with carbonate, sulfate radical, silicate etc., the formation of lime carbonate etc. in the anti-effectively sealing, stop the formation of incrustation scale in the drip irrigation pipe, thus solve in the drip irrigation facility dropper and drip block problem.
The technical solution adopted in the present invention is: when the composite fertilizer of the traditional 15-15-15 prescription of preparation, in composition of raw materials, reduce the usage quantity of diammonium phosphate or monoammonium phosphate, reduction is total 7-30% that drops into raw material by weight percentage, add the polyphosphate mixture of respective amount then, raw material is put into reactor, prepare high concentration compound fertilizer for drip irrigation through granulation.Described polyphosphate mixture is meant that in tripolyphosphate ammonium, Hexamethylphosphoric acid triamide, Potassium tripolyphosphate, hexa metaphosphoric acid potassium, tripoly phosphate sodium STPP or the Sodium hexametaphosphate 99 one or two or more kinds is with any mixed.
The preparation feedback equation of above-mentioned tripolyphosphate ammonium, Hexamethylphosphoric acid triamide, Potassium tripolyphosphate, hexa metaphosphoric acid potassium, tripoly phosphate sodium STPP and Sodium hexametaphosphate 99 is as follows:

The invention has the advantages that:
1, for farm crop provide full nutrition fertilizer, the content height of nitrogen, phosphorus, potassium composition has highly enriched property and solvability.
2, difference that can with good grounds farm crop kind, and, redefine the kind and the content ratio of nitrogen, phosphorus, potassium at the different needs of different growing stages.
What 3, no matter use is surface water or underground water, and the concentration that adds composite fertilizer is much, can both guarantee drip irrigation facility non-scaling, guarantees drip irrigation installation security works better.
