Ox hair keratin coated slow-release fertilizer capable of improving saline and alkaline land and preparation method of slow-release fertilizer

Abstract

The invention discloses ox hair keratin coated slow-release fertilizer capable of improving saline and alkaline land. The ox hair keratin coated slow-release fertilizer is prepared from raw materials in parts by weight as follows: 20-21 parts of ox hair, 20-22 parts of Chinese honeylocust fruits, 75-80 parts of reed, 30-34 parts of potatoes, 40-42 parts of waste paper, 50-55 parts of tea seed meal, 15-17 parts of wheat middling, 30-35 parts of bentonite, 1-1.5 parts of ammonium nitrate, 2-3 parts of ardealite, 1-1.5 parts of sodium acid pyrophosphate, 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 lauryl sodium 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 slow-release fertilizer can improve the soil, and added phosphogypsum can improve the saline and alkaline land.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a cow hair keratin-coated slow-release fertilizer capable of improving saline-alkali land 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 ...
