Embodiment 1

[0008] Put the 10% weight percentage of the rubber bowl extract into the reaction kettle, dissolve it in water with a 14% weight percentage of the composition, then adjust the pH to about 7.5 with sodium hydroxide, and add 2.1% weight percentage of the component hydrogen peroxide, and reacted at 80°C for 1.5 hours. Then, add the gallic acid that component weight percent is 6% in the reactor. Then add manganese sulfate with a component weight percentage of 50% and the rest of water into the reaction kettle, carry out complexation reaction at 90° C. for 1 hour, and filter the solution with a 100-mesh sieve after the process is completed. Finally, add sodium dodecylbenzenesulfonate with a component weight percentage of 2.5% into the filtrate and stir evenly to obtain the final product.

Embodiment 2

[0010] The operating procedure was the same as in Example 1 during preparation. Just change the raw material type, quantity, dissolution temperature and reaction time within the scope specified by the operation procedure of the present invention, and still prepare the organic manganese fertilizer of the present invention in the same way.

Abstract

The invention provides a process for producing organic manganese fertilizer, which is prepared from the raw material constituents of inorganic manganese, polyhydric phenol carboxylic compound, auxiliary agent and water through complexing (chelating) reaction under a predetermined condition. The advantages include stable performance, persistent effect, and high biological effectiveness. The fertilizer has substantial effect in promoting vegetation, preventing and treating physiological diseases caused by plantsí» manganese deficiency.

Description

technical field [0001] The invention relates to a production method of chemical fertilizer, in particular to a production method of organic manganese fertilizer. Background technique [0002] Manganese is an essential trace element for plants, and the application of manganese fertilizer is a fundamental measure to balance fertilization and ensure the supply of manganese nutrients for crops. Organic complexing (chelating) micro-fertilizers can overcome the adverse consequences caused by oxidation, antagonism, and precipitation after the application of inorganic micro-fertilizers. It has the advantages of stable fertilizer efficiency, easy absorption by plants, and high utilization rate. The main direction of industrial development. Existing fertilizers containing organic manganese are often organic complex fertilizers with multiple nutrients including manganese, and there is no organic complex fertilizer specific to manganese nutrients, which is harmful to some soils and cro...
