Multifunctional organic/inorganic compound fertilizer and preparation method thereof

Abstract

The invention provides a multifunctional organic/inorganic compound fertilizer and a preparation method thereof. The compound fertilizer is composed of the following raw materials by weight percent: 25-30% of urea, 5-10% of monoammonium phosphate, 10-18% of potassium sulphate, 27-32% of humic acid, 1.5-3% of zinc sulfate, 0.1-0.3% of microorganism bacterial liquid, 12-20% of diatomite and 1.9-2.7% of sophorolipid, wherein humic acid is obtained from decomposed coal through activation treatment. During preparation, urea, monoammonium phosphate, potassium sulphate, humic acid, zinc sulfate, microorganism bacterial liquid, diatomite and sophorolipid are added to a mixing crusher for crushing, so that a powdery mixture is obtained; the powdery mixture is added to a drum coating-pelleting-drying-cooling integrated machine to be pelleted, dried and cooled so that a granular mixture is obtained; the microorganism bacterial liquid and the diatomite are mixed and then sprayed to the mixture so that a crude product of the multifunctional organic/inorganic compound fertilizer is obtained; and finally, the crude product is added to a vibrating sieve for screening and then the obtained oversize is the multifunctional organic/inorganic compound fertilizer.

AI Technical Summary

Benefits of technology

This patented technology allows for combining different types of chemical substances into one product with improved effectiveness compared to traditional methods like adding other nutrients or pesticides separately. By activated Humulones Sulfur Nitrates (HNS), this method enhance their ability to stimulate root growth by promoting cell division within roots cells without harmful side effects such as reducing water absorption from plants' leaves. Additionally, Hydroxypropyltoluene-2 -thiolsulfonamide(HPTESA2) have been found effective at increasing pigments production during ripening processes due to its antioxidative properties against free radical reactions caused by oxygen species present inside vegetables. These technical results improve the functionality and longevity of crops grown under various conditions through these combined products.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the effectiveness of humidifying agents (humins) during production processes due to their high reactivity towards water vapor or other gases present at room temperature. These reactive materials can easily lose some moisture when exposed to air over several hours' storage before being applied on plants. Therefore, there has been an effort to develop methods to protect these chemical substances from losing them while still allowing effective absorption into plant roots.
