Problems solved by technology

The nitric acid degradation method will cause great pollution to the environment, and its application is limited
When hydrogen peroxide is added to the coal-water mixture solution, it will react with fulvic acid and heat up sharply, and will evaporate rapidly with the temperature rise, making it difficult to continue the reaction. Slowly adding hydrogen peroxide will reduce the temperature growth rate,

Embodiment 1

[0034] A method for preparing a large, medium and trace element water-soluble fertilizer containing fulvic acid, comprising the following steps:

[0035] 1) Take one-year straw, after segmenting, cutting, screening, and removing impurities, add calcium oxide and potassium hydroxide solution to soak for 4 days;

[0036] 2) Add water, soybean meal, and rapeseed cake for ingredients, then add Bacillus subtilis, stir thoroughly, enter the fermentation tank for 4 days of fermentation and decomposing treatment, fully stir again and ferment and decompose for 4 days, wherein the fermentation temperature is maintained at 65 degrees ;

[0037] 3) Take the fermented liquid that has been fermented for 8 days and carry out solid-liquid separation and impurity removal to obtain the primary fermented liquid. After the primary fermented liquid is left to stand and settle, the supernatant is extracted and put into a centrifuge for centrifugation and impurity removal twice, and then left to sta...

Abstract

The invention provides a fulvic acid-containing large-medium-trace element water-soluble fertilizer and a preparation method thereof, wherein the fulvic acid-containing large-medium-trace element water-soluble fertilizer comprises, by mass, 50-90% of fulvic acid, and 10-50% of water-soluble elements, wherein the water-soluble elements comprise large water-soluble elements of potassium dihydrogen phosphate and urea, medium water-soluble water-soluble elements of ammonium calcium nitrate and magnesium sulfate, trace water-soluble elements of zinc sulfate, manganese sulfate, ferrous sulfate, copper sulfate and ammonium tetramolybdate, alginic acid and a chelating agent. Compared with the preparation method in the prior art, the preparation method of the present invention has the following characteristics that fulvic acid is produced by using local straw, rape, corn stalk herb waste as raw materials, and a variety of large-medium-trace elements capable of improving the absorption rate of crops are added, such that the fulvic acid-containing large-medium-trace element water-soluble fertilizer is prepared, the environment is improved, the cost of the fulvic acid water-soluble fertilizeris reduced, the benefits of enterprises are increased, and the competitiveness of enterprises is enhanced.

Description

technical field [0001] The invention relates to a water-soluble fertilizer, in particular to a water-soluble fertilizer with large, medium and trace elements containing fulvic acid and a preparation method thereof. Background technique [0002] Straw, rapeseed, corn stalks and other herbaceous plants are usually treated by burning them in large quantities in the most direct way. This treatment method will cause air pollution, endanger human health, cause fires, and threaten the lives and property safety of the masses. At the same time, It will also cause traffic accidents, affect road traffic and aviation safety, and will damage the soil structure, resulting in a decline in the quality of cultivated land, affecting the full absorption of soil nutrients by crops, directly affecting the yield and quality of farmland crops, and affecting agricultural income. [0003] With the rapid development of the chemical industry, the production and application of various fertilizers have ...
