Problems solved by technology

[0002] At present, most of the commonly used extraction methods for fulvic acid have low extraction efficiency. At the same time, due to improper temperature control, the activity of fulvic acid is not strong, and the weathered coal used cannot be fully utilized.
Humic acid products on the market, in addition to simple anti-drought agents, generally contain hormones (that is, plant growth regulators). Although the effect is quick, the duration of the fertilizer effect is short, and the nutrition is not comprehensive enough.

Embodiment 1

[0018] Firstly, the raw material weathered coal is screened to remove impurities and crushed, and then take 0.2 tons of the weathered coal that has been pre-treated and put it into the reaction kettle, and add 0.2m of cold water at the same time 3 , the concentration is 30kg of 50% nitric acid, after stirring evenly, add 25kg of potassium pyrophosphate, at the same time add 0.6m 3 The cold water is heated to boiling and poured into the reaction kettle, then add 60kg of 98% concentrated sulfuric acid, fully stir the material in the reaction kettle to carry out the extraction reaction, the temperature of the reaction kettle is controlled at 85°C, and the reaction time is 25 minutes. After the reaction is finished and cooled naturally, Allow the reactant in the reactor to stand and settle for 24 hours. There is a solid-liquid separation state in the reaction kettle. At this time, use an anti-corrosion pump to pump the crude liquid above to the centrifuge, and remove the residue i...

Embodiment 2

[0020] First, sieve the raw material weathered coal to remove impurities and pulverize it, then take 0.2 tons of the weathered coal that has been pre-treated and put it into the reaction kettle, and add 0.2m of cold water at the same time 3 , the concentration is 30kg of 50% nitric acid, after stirring evenly, add 25kg of potassium pyrophosphate, at the same time add 0.6m 3 The cold water is heated to boiling and poured into the reaction kettle, then add 60 kg of 98% concentrated sulfuric acid, fully stir the material in the reaction kettle for extraction reaction, the temperature of the reaction kettle is controlled at 86 ° C, and the reaction time is 30 minutes. After the reaction is finished and cooled naturally, Allow the reactant in the reactor to stand and settle for 24 hours. There is a solid-liquid separation state in the reaction kettle. At this time, use an anti-corrosion pump to pump the crude liquid above to the centrifuge, and remove the residue in the reactor. Th...

Abstract

The present invention relates to a high-effective drought-resisting fertilizer and its preparation process. It is made up by mixing fulvic acid extracted from danty, cupric sulfate, ferrous sulfate, manganese sulfate and zinc sulfate according to a certain proportion, and is characterized by that in the process of extracting fulvic acid firstly, a certain quantity of concentrated nitric acid is added so as to make the ulmic acid and humic acid be converted into the fulvic acid to raise extracting rate of fulvic acid. Its main preparation process includes the steps of extracting fulvic acid and adding trace elements. Besides, it also provides application method.

Description

technical field [0001] The invention relates to a high-efficiency drought-resistant fertilizer composed of fulvic acid and trace elements in weathered coal and a preparation process thereof. Background technique [0002] At present, most of the commonly used extraction methods for fulvic acid have low extraction efficiency. At the same time, due to improper temperature control, the activity of fulvic acid is not strong, and the weathered coal used cannot be fully utilized. Humic acid products on the market, in addition to simple anti-drought agents, generally contain hormones (that is, plant growth regulators). Although the effect is quick, the duration of the fertilizer effect is short, and the nutrition is not comprehensive enough. Today's society increasingly needs green agricultural products, which requires high-efficiency green fertilizers, so pesticide residues have become a serious obstacle to the development of contemporary agriculture. Contents of the invention ...
