Micronutrient fertilizers, often referred to simply as trace elements. It refers to a fertilizer containing micronutrients and having low crop absorption consumption (relative to a macroelement fertilizer). Although trace elements are required in crops in small quantities, they are equally important to crops as macroelements and cannot be replaced by each other. The application of the micro-fertilizer can play the fertilizer effect on the basis of nitrogen, phosphorus and potassium fertilizers. Meanwhile, the crop reaction to the trace element rope is different under different nitrogen, phosphorus and potassium levels.

A. weighing 11 parts of ferrous sulfate and 11 parts of EDTA disodium by weight, mixing the materials, adding the mixture into a reaction kettle, adding water into the reaction kettle, stirring for 10min at normal temperature and normal pressure, heating the reaction kettle to 60-75 ℃, reacting for 0.5-1.5h, and filtering out insoluble impurities;
B. and C, concentrating the filtrate obtained in the step A, carrying out centrifugal separation when a large amount of crystals appear, and drying and grinding the separated crystals to obtain the finished product of EDTA chelated iron, wherein the iron content is required to be more than or equal to 13%.
The EDTA chelated copper is prepared according to the following method:
A. weighing 7 parts of copper sulfate and 7 parts of EDTA disodium by weight, mixing the above substances, adding the mixture into a reaction kettle, adding water into the reaction kettle, stirring for 10min at normal temperature and normal pressure, heating the reaction kettle to 60-75 ℃, reacting for 0.5-1.5h, and filtering out insoluble impurities;
B. and C, concentrating the filtrate obtained in the step A, performing centrifugal separation when a large amount of crystals appear, and drying and grinding the separated crystals to obtain the finished product of EDTA chelated copper, wherein the copper content is required to be more than or equal to 15%.
The EDTA chelated manganese is prepared according to the following method:
A. weighing 7 parts of manganese sulfate and 7 parts of EDTA disodium according to parts by weight, mixing the above substances, adding the mixture into a reaction kettle, adding water into the reaction kettle, stirring for 10min at normal temperature and normal pressure, heating the reaction kettle to 60-75 ℃, reacting for 0.5-1.5h, and filtering out insoluble impurities;
B. and C, concentrating the filtrate obtained in the step A, performing centrifugal separation when a large amount of crystals appear, and drying and grinding the separated crystals to obtain the finished product of EDTA chelated manganese, wherein the manganese content is required to be more than or equal to 13%.
A preparation method of a chelated compound trace element fertilizer comprises the following steps:
weighing 15 parts of EDTA chelated zinc, 11 parts of EDTA chelated iron, 7 parts of EDTA chelated copper and 7 parts of EDTA chelated manganese according to the weight parts, and uniformly mixing the components after the components are distributed in proportion to prepare chelated trace elements;
weighing 0.3-2 parts of chelated trace elements, 4-6 parts of instant boron, 0.2-0.5 part of ammonium molybdate, 1.5-3 parts of potassium sulfate, 0.5-1 part of mineral fulvic acid and 5-8 parts of magnesium sulfate monohydrate according to the weight parts, and sequentially adding the raw materials into a pulverizer for pulverization;
step three, sequentially putting the raw material powder crushed in the step two into a mixer for uniform stirring;
and step four, sieving the mixture stirred in the step three, and filling and packaging.
The invention has the beneficial effects that:
1. the fertilizer is not easy to be fixed in soil, is easy to dissolve in water, is not dissociated, can be well absorbed and utilized by plants, enhances the resistance of the crops, improves the yield of the crops and improves the activity of the crops. Can also be mixed with other solid or liquid fertilizers for application without chemical reaction, and the fertilizer efficiency of any fertilizer is not reduced;
2. the EDTA chelated zinc can enhance the photosynthesis of crops, promote the synthesis of phytogenin and enhance the disease resistance and cold resistance of crops; the EDTA manganese can enhance photosynthesis, regulate the oxidation and reduction conditions in crops, is beneficial to the growth and development of crops and reduces the infection rate of crop diseases; the compound EDTA chelates trace elements such as iron and copper, is beneficial to the generation of chlorophyll, promotes nitrogen metabolism, enhances photosynthesis, enhances disease resistance, improves cold resistance and drought resistance, promotes the development of cell walls, improves the selective absorption capacity of biological membranes, improves the sugar content of crops such as fruits and vegetables and the like, thereby improving the quality of the crops;
