Root-strengthening cattle hair keratin coated controlled-release fertilizer and preparation method thereof

Abstract

The invention discloses a root-strengthening cattle hair keratin coated controlled-release fertilizer. The fertilizer is prepared from, by weight, 20-21 parts of cattle hair, 50-55 parts of cottonseed hulls, 40-45 parts of sugarcane leaves, 45-46 parts of pomace, 30-32 parts of shrimp shells, 30-32 parts of weathered coal, 25-30 parts of hawthorn seeds, 1-1.1 parts of paclobutrazol, 1-1.2 parts of calcium superphosphate, 1-1.2 parts of ammonium sulfate, 1.2-1.5 parts of polyacrylamide, 0.9-1 part of diethyl aminoethyl hexanoate, 40-45 parts of bentonite, 0.2-0.3 part of fatty acid methyl ester ethoxylate, 0.2-0.3 part of sodium carbonate, 20-21 parts of mercaptoethanol, 18-19 parts of urea, 3-4 parts of lauryl sodium sulfate, 0.2-0.3 part 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 glycerine, 0.2-0.3 part of borax and 2-2.5 parts of microbial bacterium powder. The fertilizer can effectively improve the granular structure of soil, promote the growth of crop roots and strengthen the roots.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a slow-release fertilizer coated with root-solid ox 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 problems ...
