Abstract

The invention discloses a fertilizer nutrient controlled-release coating agent which is prepared from the following components in parts by weight: 12-17 parts of polypeptide slow-release agent, 2-12 parts of additive, 8-12 parts of white vitriol, 35-45 parts of amino acid, 4-6 parts of water-soluble silicon, 4-6 parts of sodium molybdate dihydrate, 4-6 parts of chelator, 4-6 parts of rare-earth and 4-6 parts of microelement. The coating agent has the advantages of favorable controlled-release effect, abundant fertilizer nutrients and the like, is convenient to use, and enhances the crop yield.

Description

Technical field [0001] The invention relates to the field of chemical fertilizers, and in particular provides a fertilizer nutrient controlled release coating agent. Background technique [0002] Fertilizer, as the main source of plant nutrients and improving soil properties, is of great significance for promoting plant growth and increasing the yield of food, fruits and vegetables. The current fertilizers mainly include chemical fertilizers, organic fertilizers and biological fertilizers. With the development of industrial fertilizers, people's requirements for fertilizers are also increasing. Therefore, fertilizer coating technology has begun to appear. Although the current fertilizer coating agents have slow-release fertilizer effects, the slow-release effects are still not good. [0003] Therefore, how to improve the controlled-release coating to increase its controlled-release effect while enriching the nutrients of fertilizers has become an urgent problem to be solved.
