Problems solved by technology

Excessive use of chemical fertilizers causes soil compaction, salinization, and loss of soil fertility year by year
In addition, the long-term use of chemical fertilizers makes the quality of crops worse and worse, and the taste of food is lost after being made into food. This is a problem that people generally perceive at present. Especially the application of chemical fertilizers to vegetables makes the fruit nitrate test more than 1000mg / kg, seriously exceeding the standard (National standard: Grade A products should be less than 600mg / kg)
What's more serious is that the human body absorbs too much nitrate from vegetables, and the nitrate and amines in the stomach and intestines synthesize extremely strong carcinogen ammonium nitrate, leading to a high incidence of gastric cancer and esophageal cancer.

Abstract

The invention relates to a preparation method of a humic acid organic fertilizer, which comprises the following steps: taking hydrogen peroxide, ammonium bicarbonate, triple superphosphate, potassium sulfate, sodium hydroxide, potassium permanganate, zinc sulfate, borax, ferrous sulfate, sodium carbonate and lignite as raw materials; adding lignite powder, the sodium carbonate and the hydrogen peroxide into a reaction kettle, carrying out cracking and oxidation, and producing mixture containing humic acid; adding the potassium permanganate and the potassium sulfate, and producing the mixture containing potassium humate; adding the ammonium bicarbonate, the triple superphosphate and the sodium hydroxide, carrying out complexing reaction and producing the humic acid organic fertilizer; and adding the zinc sulfate, the borax and the ferrous sulfate, carrying out chelating reaction and producing the humic acid organic fertilizer. The prepared product fertilizer has comprehensive nutritionand can improve the in vivo activity of crops, increase the fertilizer efficiency, promote the rapid and long-term nutrition absorption of the crops, enhance the anti-disease capacity of the crops, increase the yield and improve the product quality of the crops.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to a preparation method of humic acid organic fertilizers. Background technique [0002] The research on humic acid organic fertilizer in my country started in 1974 out of the needs of agricultural development. The State Council approved and forwarded the request report of the Ministry of Raw Fuel Chemical Industry and the Ministry of Agriculture and Forestry on the test and promotion of humic acid fertilizers, which set off a nationwide research and production of humic acid fertilizers. Acid fertilizer boom. After 1977, the research and development of humic acid in our country gradually embarked on the track of scientific development. [0003] From the 1990s to the present, the world has entered the era of green industrial revolution and circular economy. Although my country is also implementing the strategic decision of harmonious development between man an...
