Problems solved by technology

[0003] After the existing trace elements are added to fertilizers in the form of inorganic salts or directly applied to the soil, most of the added trace elements are eliminated due to the antagonism between some elements, the chemical reaction between them and the interaction of various ions in the soil. The soil is fixed and water-insoluble inorganic salts are produced, so there is a technical problem that it is difficult to be absorbed and utilized by plants

Embodiment 1

[0022] Chelation device: the device consists of a first-level chelation reaction kettle, a second-level chelation reaction kettle, a third-level chelation reaction kettle, a fourth-level chelation reaction kettle, a pump and a steam boiler. The steam boiler provides heating steam for the chelation reactors at all levels. The reactors at all levels are constant temperature reactors. The jacket is filled with water as the heat storage and heating carrier. The condensed water and excess steam that come out of the set are all collected and recycled and returned to the steam boiler as soft water preheating.

[0023] Preparation method: Put 20kg of potassium fulvic acid, 10kg of zinc sulfate, 10kg of magnesium sulfate, 10kg of ferrous sulfate, and 5kg of copper sulfate into the first-level chelation reaction kettle, and adjust the moisture content of the materials in the first-level chelation kettle to 18%. Increase the temperature of the primary reactor to 30°C, react for 24 minute...

Embodiment 2

[0025] The chelating device is the same as in Example 1.

[0026] Preparation method: Put 40kg of potassium fulvic acid, 20kg of zinc sulfate, 20kg of magnesium sulfate, 20kg of ferrous sulfate, and 10kg of copper sulfate into the first-level chelation reaction kettle, and adjust the moisture content of the materials in the first-level chelation kettle to 25%. Increase the temperature of the reactor to 35°C, react for 48 minutes, and control the temperature rise of each stage at 10°C, and transfer the chelated product of the first-stage reaction reactor to the After 18 minutes of reaction in the secondary chelation reactor, transfer the chelated product from the secondary reactor to the third-stage chelation reactor through the pump connected to the secondary chelation reactor and the third-stage chelation reactor. The pumps of the three-stage chelation reactor and the four-stage chelation reactor transfer the chelation product from the third-stage reactor to the fourth-stage ...

Abstract

The invention discloses a potassium fulvate chelating multivariate medium trace element soil improvement agent and a preparation process thereof. The process specifically comprises the steps of adding each component into a first-stage chelating reaction kettle, adjusting the moisture content of materials in the first-stage chelating reaction kettle to be 18-25%, and then sequentially performing a heating reaction by using fourth-stage chelating reaction kettles to obtain a final liquid product, wherein the prepared soil improvement agent comprises the following components in parts by weight: 15-30 parts of organic matter, 10-20 parts of zinc chelate, 10-20 parts of iron chelate, 10-30 parts of magnesium chelate, 1-5 parts of copper chelate, 1-5 parts of manganese chelate, 1-5 parts of molybdenum chelate, 2-3.5 parts of organic nitrogen, 2-3.5 parts of organic phosphorus and 2-3.5 parts of organic potassium. The preparation process disclosed by the invention can be used for performing continuous material feeding and continuous discharging production, and is high in chelating efficiency and short in time; a product has the effects of regulating the physical balance, chemical balance and biological balance of soil, and organically combines land use and land maintenance.

Description

technical field [0001] The invention relates to a potassium fulvic acid chelated multi-component microelement soil improver and a preparation process thereof. Background technique [0002] At present, the chemical fertilizer industry focuses on the technical progress of the existing traditional chemical fertilizers, mainly to improve the quality and reduce the cost, which itself acts as one of the culprits of the deterioration of the soil environment. [0003] After the existing trace elements are added to fertilizers in the form of inorganic salts or directly applied to the soil, most of the added trace elements are eliminated due to the antagonism between some elements, the chemical reaction between them and the interaction of various ions in the soil. The soil is fixed and water-insoluble inorganic salts are produced, so there is a technical problem that it is difficult to be absorbed and utilized by plants. Contents of the invention [0004] Aiming at the above proble...
