Method for preparing protein peptide fertilizer by using rice residues

Abstract

The invention provides a method for preparing a protein peptide fertilizer by using rice residues. The method comprises the following steps: (1) steaming the rice residues in a pot with water, after water in the pot is boiling, continuing steaming for 20 minutes, taking out and cooling to room temperature, filtering and drying to obtain rice residue powder; (2) adding the rice residue powder obtained from the step (1) and an enzyme microorganism inoculant in a fermenting vat, stirring evenly, then adding brown sugar water and rice vinegar, stirring evenly, covering an opening of the fermenting vat by using three layers of gauzes and tying with a rope, placing the fermenting vat in an indoor environment and fermenting; (3) in the fifth day to the sixteenth day at the beginning of fermenting, stirring the fermenting vat once every day, immediately covering again after stirring, stopping fermenting after materials in the fermenting vat are blocky and do not have odor, opening the gauzes and air-drying; and (4) transferring the air-dried fermented materials into a container, after soaking with the brown sugar water for 20 days, taking out and packing to obtain the protein peptide fertilizer, and storing the protein peptide fertilizer in a shady, cool and dry place. The method is simple to operate, low in preparation cost and wide in application range.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a method for preparing protein peptide fertilizers from rice dregs. Background technique [0002] With the rapid development of the global economy and society, people's quality of life has been improved and improved, and the demand for high-protein foods and protein products is increasing, resulting in an increasing shortage of protein resources. Therefore, it is of great significance to develop and utilize existing and potential protein resources, recycle them, and turn waste into wealth to alleviate the shortage of protein resources in our country. [0003] Studies in recent decades have found that there is a peptide substance, which has incomparable physiological characteristics of proteins and amino acids, and its absorption mechanism is better than that of proteins and amino acids. This peptide substance is a molecular polymer between protein and amino ac...

Problems solved by technology

Urea is a quick-acting fertilizer, which has a very fast effect on plant growth. Usually, plants can turn green in 5-7 days, but urea is easy to volatilize, and it is easy to lose and cause non-point source pollution. At the same time, it is easy to cause soil compaction; compound fertilizer also has the characteristics of urea. Contains urea; organic fertilizer is the best fertilizer, but its characteristic is that the fertilizer effect is particularly slow (more than 20 days)
