Abstract
The present invention relates to a technology for producing a fertilizer comprising organic chelating microelements, which comprises the following steps: humus is extracted from brown coal; needed liquid is obtained by precipitation; citric acid as an organic chelating agent or the salt of the citric acid and microelements are added; obtained liquid is adjusted to neutrality by a pH value, and after a drying process, the product of the present invention is obtained. The present invention has the advantages that the components of the extracted product comprises the component of the humus of soil stabilization, the present invention is the present only technological process reserving all the effective humus in the extracted product by organically chelating and preparing acid and alkali, and the problem of the influence of use effect because of bad stability and easy decomposition caused by the present the prior art simply mixing humic acid and the microelements is solved. The product of the present invention is used for agricultural production.
Description
Technical field
The present invention relates to the production technique of agricultural fertilizer, specifically, relate to from brown coal and leonardite, extract corruption and plant metallic substance, and the micronutrient element required with plant, by chemical reaction, generate organic chelated Medium Trace Element Fertilizer technology.
Background technology
Synthetic little fertilizer on the present fertilizer market, no matter be soil application, or foliage-spray, effect is not very desirable.Little fertilizer generally has little fertilizer of inorganic salts and organic chelated trace fertilizer, utilization ratio in use is all lower, the switched-media that matter is the nutritive ingredient in the soil is planted in corruption, simultaneously, it also is good organic sequestering agent, corruption is planted matter and is passed through chelatropic reaction with trace element, and the little fertilizer of matter is planted in the corruption that generate the solubleness height, is easily absorbed by crop, improves crop greatly to the trace elements absorbed utilization.
Brown coal and leonardite are acknowledged as the main source of diversified humate and humic acids, and, contain multiple metal ion in brown coal and the leonardite, as sodium, potassium, copper, magnesium, zinc etc.At present, have some simply extract humic acids from brown coal technology, but the imperfection of this technology and other technologies aspect does not reach with trace element chelated, improves the purpose of element utilization rate of fertilizer, thereby influences result of use.Therefore, the little fertilizer of humic acids that uses current prior art to produce exists the inconsistent and unconspicuous problem of crop beneficial effect.Up to today, plant matter about the corruption of from brown coal, extracting efficient stable, and take organic compound and chelatropic reaction, produce rotten technology of planting matter chelated microelement fertilizer, do not appear in the newspapers and application.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, and provide that a kind of preparation method is easy, effect is preferably from brown coal and leonardite, plant metallic substance and micronutrient element by corruption that organic chelated reactant extracts, form the production technology of organic chelated microelement fertilizer by chemical reaction.
The objective of the invention is to finish by the following technical solutions, organic chelated Medium Trace Element Fertilizer technology, carry out according to following steps, 1, the organic chelate that matter is planted in corruption extracts, in being heated to 80 ℃-100 ℃ liquid reaction medium water, add brown coal or leonardite and organic chelated reactant: gluconic acid, tartrate, tartronic acid, pentanedioic acid or EDTA, the part by weight scope of brown coal and water is 1: 5-10, brown coal and gluconic acid, tartrate, tartronic acid, the part by weight scope of pentanedioic acid or EDTA is respectively 1: 0.5-0.8,1: 0.6-0.8,1: 0.7-0.9,1: 1.0-1.2,1: 0.15-0.45, reaction times is 30-60 minute, extract corruption and plant matter, through precipitation, liquid is required product; 2, in the liquid of gained, add alkaline matter sodium hydroxide or potassium hydroxide, continue abstraction reaction, the part by weight scope of brown coal and sodium hydroxide or potassium hydroxide is 1: 0.10-0.20, the reaction times is 240-300 minute; 3, in next step reaction process, add hydrogen peroxide, with the weight ratio of brown coal be 1: 0.02-0.05, proceed oxidizing reaction, the reaction times is 120-180 minute; 4, micro-inorganic salt or the acids that adds citric acid or its esters and press formula rate, carry out chelatropic reaction, the part by weight scope of brown coal and citric acid or its esters is 1: 0.25-0.40, the part by weight scope of brown coal and micro-inorganic salt or acids is 1: 0.80-1.20, trace element inorganic salt or acids comprise following kind: boric acid, borax, copper sulfate, ferrous sulfate, manganous sulfate, zinc sulfate or ammonium molybdate, and the reaction times is 120-180 minute; 5, allocate according to the potential of hydrogen of final chelatropic reaction, make final potential of hydrogen reach neutral, the adjusting time is 10-30 minute; 6, after sufficient reacting is finished, make dried process according to a conventional method, can obtain the finished product.
The present invention compares with the prior art of the little fertilizer of tradition has following advantage, the present invention is by organic chelated technology, the matter chelated trace fertilizer is planted in the production corruption, and it is complete that the component of matter is planted in corruption, carries out sufficient chelatropic reaction with trace element in the reaction process, product stability is good, effectively improved trace element utilizing rate, reduced total usage quantity, it is simple to have solved present technology, utilization ratio does not have the problem that obviously improves, uses that this product consumption is little, safe and reliable, specific absorption is high.
Specific implementation method
Enumerate 1 embodiment below, the present invention is further specified, but the present invention is not only limited to this embodiment
Embodiment 1
Liquid reaction medium water 60kg is heated to temperature range between 80 to 100 ℃, brown coal or leonardite 10kg, join in the heating liquids reaction medium water, add at least a following reaction raw materials, gluconic acid 5kg, tartrate 6kg, tartronic acid 7kg, pentanedioic acid 10kg, EDTA2kg, the reaction times is 30-60 minute.
Add sodium hydroxide 1kg or potassium hydroxide 1kg, continue abstraction reaction; Reaction times is 240-300 minute.
