Efficient cow hair keratin coated slow-release fertilizer and preparation method thereof

Abstract

The invention discloses an efficient cow hair keratin coated slow-release fertilizer which is prepared from the following raw materials in parts by weight: 20-21 parts of cow hair, 70-75 parts of soybean straw, 20-22 parts of potassium feldspar, 40-45 parts of citric acid residue, 30-33 parts of chicken liver powder, 30-32 parts of broad been skin, 13-15 parts of tenebrio molitor, 30-32 parts of sludge, 30-32 parts of kieselguhr, 2-3 parts of soybean oligosaccharide, 1.5-1.6 parts of compound sodium nitrophenolate, 1-1.1 parts of brassinolide, 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 glutamine transaminase, 3-4 parts of starch, 18-20 parts of 10% polyvinyl alcohol solution, 7-8 parts of 5% carboxymethylcellulose solution, 4-5 parts of formaldehyde, 5-6 parts of glycerin, 0.2-0.3 part of borax and 2-2.5 parts of microbial bacteria powder. The efficient cow hair keratin coated slow-release fertilizer disclosed by the invention has good fertilizer efficiency and can promote seed germination.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a high-efficiency cow hair keratin-coated slow-release fertilizer 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...

Problems solved by technology

Since cowhide tanning adopts clean production technology, cow hair recovered by hair preservation and depilation has been faced with the problem of how to recycle it, because it has been processed by chemical materials and mostly has a deep color, so it is difficult to recycle it.
