Bactericidal ox hair keratin-coated slow-release fertilizer and preparation method thereof

Abstract

The invention discloses a bactericidal ox hair keratin-coated slow-release fertilizer. The bactericidal ox hair keratin-coated slow-release fertilizer is prepared from, by weight, 20-21 parts of ox hair, 80-83 parts of sugarcane peel, 80-85 parts of fallen leaves, 55-60 parts of soybean meal, 7-8 parts of malt sugar, 35-40 parts of bentonite, 20-22 parts of turfy soil, 10-11 parts of calcium powder, 24-25 parts of mineral powder, 1-1.2 parts of tea polyphenol, 30-32 parts of mosquito-repellent incense ash, 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 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 part of borax and 2-2.5 parts of microbial powder. The fertilizer achieves the bactericidal effect by adding tea polyphenol and the mosquito-repellent incense ash.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a sterilizable 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 th...
