This application is compared and is few with traditional product use amount to can replenish iron fast, solve between the medium trace element because of the unbalanced problem of absorption that the antagonism leads to.
Description
Technical Field
The invention relates to a medium trace element and a preparation method and a use method thereof.
Background
The crop growth needs 16 elements, wherein carbon, hydrogen, oxygen, nitrogen, phosphorus and potassium are major elements, calcium, magnesium and sulfur are middle elements, boron, iron, manganese, zinc, chlorine, molybdenum and copper belong to trace elements, the functions of various elements in plants are different and cannot be replaced mutually, wherein iron participates in the formation of chlorophyll, and the iron deficiency of plants can cause the upper tender leaves of the plants to lose green and yellow, however, the iron deficiency of the crops is found to yellow in reality, and even if a large amount of iron fertilizer such as ferrous sulfate or chelated iron is applied to the iron deficiency crops, the tender leaves are still not seen to turn green.
Many times, the plant is lack of trace elements, which are not single-shot and are often mixed, so that several kinds of medium trace elements are usually needed to be supplemented together, and antagonism exists among the medium trace elements, so that the problem of unbalanced absorption exists during simultaneous supplementation.
At present, no better iron supplement product exists, and the problem of unbalanced absorption caused by antagonism due to simultaneous supplement of medium and trace elements is not solved.
Disclosure of Invention
The invention provides a medium trace element and a preparation and use method thereof, which solve the technical problems that 1) the iron supplement effect is good; 2) the medium and trace elements are not balanced in plant absorption due to antagonism among the medium and trace elements.
In order to solve the technical problems, the invention adopts the following technical scheme:

The organic acids and salts thereof are electron donors.
The organic acid and the salt thereof are one or more of acetic acid, sodium acetate, lactic acid, potassium lactate, sodium pyruvate and pyruvic acid.
Also comprises one or more of medium elements, major elements, wetting agent and sugar alcohol.
The pH value is lower than 6.5.
A method for preparing medium trace element comprises mixing ferrous iron providing substance, organic acid and its salt and iron reducing bacillus, and stirring.
The mass ratio of the ferrous iron, the organic acid and the salt thereof to the iron reducing bacillus is 1-25: 0.02-10: 0.01-5, and the content of the ferrous iron is higher than that of any other single component in the composition.
The mixing is uniformly mixing in a closed drying device.
A method for using medium and trace elements comprises the steps of diluting the medium and trace elements with water until the ferrous concentration is 0.03-0.2% and the pH value is 3-6.5, then irrigating roots of the plants with the medium and trace elements, wherein the application amount of each plant is 1-5 kg, and covering soil and compacting after irrigating the roots.
The invention has the following beneficial technical effects:
1. bivalent ferrous iron is an absorption form of plant cells, has certain water solubility, and is oxidized easily to generate water-insoluble precipitate ferroferric hydroxide in an aerobic state so as to fix ferric iron, wherein the chemical reaction is as follows, taking ferrous sulfate as an example: 12FeSO4+3O2+6H2O=4Fe2(SO4)3+4Fe(OH)3And the higher the pH, the higher the 4Fe (OH) produced3The more organic acid and salt thereof are added as antioxidant to prevent ferrous iron from being oxidized into ferric iron, and meanwhile, when the organic acid and salt thereof are used, the pH value is controlled from 3-6.5, and Fe (OH) can be reduced3Thereby improving the utilization rate of ferrous iron; under the condition of no oxygen, the reaction formula of ferric iron and ferrous iron is as follows: fe (OH)3+ e- + 3H + = Fe2++ 3H2O, this reaction is conditional and conversion is very slow, the iron-reducing bacillus in this application takes organic acid and its salt as electron donor and trivalent iron as electron acceptor under anaerobic condition to speed up the electron transfer and reduce trivalent iron into divalent iron more quickly, thus increasing the utilization rate of divalent iron, at the same time, in the process of electron transfer, current is generated to ionize and move in opposite direction, thus preventing the combination of anions and cations, producing antagonistic mutual immobilization, and HPO4 2—And Fe2+For example, HPO4 2—+Fe2+-- Fe HPO4(sparingly soluble), HPO4 2—And Fe2+Are partially fixed and the presence of current makes them less likely to bind and counteract antagonism.
2. This application is diluted to ferrous concentration to be 0.03 ~ 0.2% with water, and pH is used after 3 ~ 6.5, and the purpose is in order to prevent that salt concentration is too high in the solution, causes the dehydration of iron reduction bacillus, and the fungus is inactivated, influences the result of use of this product.
3. The application method comprises the step of irrigating roots, and after the roots are irrigated, covering soil and compacting, so that the iron reducing bacilli are in an anaerobic environment, and ferric iron is converted into ferrous iron.
4. The application needs to be uniformly mixed in a closed dry environment to prevent bacteria from being activated during production and causing attenuation of the bacteria during storage, so that the application effect is influenced.
