Activated carbon slow-release zinc fertilizer and preparation method thereof

Abstract

The invention discloses an activated carbon slow-release zinc fertilizer which comprises the following components in parts by weight: 20-33 parts of zinc salt based on the weight of zinc, 10-20% of activated carbon, 20-30% of effective zinc accelerating agent and 10-15 parts of auxiliary material, wherein the weight ratio of components in the effective zinc accelerating agent is as follow: citric acid: ammonium sulfate: fermentation organic fertilizer is 2-4: 1-2: 1-3: 3-5. According to the activated carbon slow-release zinc fertilizer, based on the special property of activated carbon which is subjected to superfine grinding, effective slow release of zinc fertilizer can be realized, acting time of the zinc fertilizer can be prolonged, and the utilization rate of the zinc fertilizer can be improved.

Description

technical field [0001] The invention relates to an activated carbon slow-release zinc fertilizer and a preparation method thereof. Background technique [0002] Zinc is one of the essential trace elements for the human body. It plays an extremely important role in the growth and development of the human body. It is often hailed as the "flower of life" and "the source of intelligence". Scientists have shown that zinc participates in the metabolic process of more than 80 enzymes in the human body, especially DNA and RNA polymerases, which directly participate in the synthesis of nucleic acid and protein, cell differentiation and proliferation, and many metabolisms. There are also some enzymes in the human body that need zinc. Therefore, zinc is an essential substance in important physiological processes such as human growth and development, reproductive genetics, immune endocrine, nerves, and body fluids. Zinc deficiency will have adverse effects on various systems of the hum...

AI Technical Summary

Problems solved by technology

Currently commonly used zinc fertilizers include single-application inorganic zinc fertilizers (zinc sulfate, zinc oxide, etc.), chelated zinc (EDTA-Zn, amino acid zinc, etc.), zinc-containing compound fertilizers, etc., but these zinc fertilizers have problems And obvious deficiencies, single inorganic zinc is easy to be fixed by soil, activity and utilization rate of zinc fertilizer are low, action time is short and fertilizer effect is poor, chelated zinc environment adaptability is strong, has certain slow release, but some chelated zinc, such as The application of EDTA-Zn, etc. will have adverse effects on the environment. The amino acid zinc has strong soil activity, but its stability is low and the price is relatively high. There are many components such as zinc-containing compound fertilizer and compound fertilizer, and zinc supplementation is not targeted.
