Medium trace element containing cowhair keratin coated slow-released fertilizer and preparation method thereof

Abstract

The invention discloses a medium trace element containing cowhair keratin coated slow-released fertilizer. The medium trace element containing cowhair keratin coated slow-released fertilizer is prepared from, by weight, 20-21 parts of cowhair, 40-45 parts of peanut bran, 50-52 parts of sugar residues, 35-37 parts of corn residues, 45-50 parts of peel, 18-19 parts of spirulina powder, 20-22 parts of kieselguhr, 20-22 parts of clay, 1-1.2 parts of itaconic acid, 1.5-2 parts of calcium bicarbonate, 1.2-1.3 parts of magnesium sulfate, 1-1.1 parts of manganese sulfate, 0.8-0.9 part of ammonium molybdate, 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 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 boron and 2-2.5 parts of microorganism bacterial powder. The medium trace element containing cowhair keratin coated slow-released fertilizer contains rich medium trace elements and is high in fertilizer efficiency, the fertilize absorption level of crops can be improved, the yield can be increased, and the quality can be improved.

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 containing medium and trace elements 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 sti...

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.
