Water retention and slow release fertilizer coated with cow hair keratin and preparation method of water retention and slow release fertilizer

Abstract

The invention discloses water retention and slow release fertilizer coated with cow hair keratin. The water retention and slow release fertilizer is prepared from raw materials in parts by weight as follows: 20-21 parts of cow hair, 80-85 parts of sorghum stalks, 65-70 parts of bagasse, 30-35 parts of fish scales, 22-24 parts of bovine bones, 20-22 parts of fish meal, 40-42 parts of red mud, 1-1.2 parts of zinc humate, 1-1.2 parts of sodium alginate, 1-1.2 parts of super absorbent resin powder, 20-22 parts of attapulgite clay, 0.2-0.3 parts of fatty acid methyl ester ethoxylate, 0.2-0.3 parts of sodium carbonate, 20-21 parts of mercaptoethanol, 18-19 parts of urea, 3-4 parts of sodium dodecyl sulfate, 0.2-0.3 parts of transglutaminase, 3-4 parts of starch, 18-20 parts of a 10% polyvinyl alcohol solution, 7-8 parts of a 5% carboxymethylcellulose solution, 4-5 parts of formaldehyde, 5-6 parts of glycerin, 0.2-0.3 parts of borax and 2-2.5 parts of microbial powder. The water retention and slow release fertilizer can improve the water retention of soil.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a slow-release fertilizer coated with water-retaining bovine hair keratin and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and fertilizer is one of the most important means of production in agricultural production. However, due to the low utilization rate of common chemical fertilizers, it causes serious environmental pollution while wasting resources. This is mainly because the nutrient release rate of these fertilizers is too fast, which leads to the serious loss of fertilizer efficiency caused by the lack of time for crops to absorb them. At the same time, the unreasonable use and low quality of fertilizer products have also caused water bodies in my country to be polluted to varying degrees. Release fertilizers can solve this problem well. But for now, slow / controlled release fertilizers still have some ...
