Problems solved by technology

[0004] In the prior art, the crushed kitchen waste is usually crushed and then directly added to fermentation bacteria and functional strains for fermentation. Due to the high temperature in the fermentation process, some functional strains are not resistant to high temperature, and high temperature will cause so

Abstract

The invention discloses a liquid organic fertilizer prepared from kitchen waste, and a production process thereof, and belongs to the technical field of fertilizers. The liquid organic fertilizer comprises, by weight, 60-70 parts of kitchen waste, 15-20 parts of straw, 2-3 parts of zymophyte, 1-1.5 parts of nitrogen-fixing bacteria, 0.5-1 part of bacillus mucilaginosus, 0.2-0.5 part of purple bacteria, 3-5 parts of supplementary nutrients, 10-15 parts of potassium hydroxide solution, 4-8 parts of decomposed coal, 5-10 parts of urea, and 200-300 parts of deionized water. Nutrient substances aresupplemented, zymophyte continuously consumes the nutrient substances in the high-temperature fermentation process, after high-temperature fermentation is finished, the nutrient substances in fermentation liquor are sharply reduced, ammonium sulfate, magnesium sulfate, potassium phosphate and calcium carbonate are additionally added into the fermentation liquor to supplement elements needed by the zymophyte, the nutrient substances are kept sufficient, and the nutrient content of the zymophyte is increased. By adding the decomposed coal and a potassium hydroxide solution, the activation of the decomposed coal is facilitated, so that humic acid is converted into a soluble state, and the absorption of crops is facilitated.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to the preparation of liquid organic fertilizers from kitchen waste and a production process thereof. Background technique [0002] Kitchen waste refers to the waste generated in the daily life of residents and activities such as food processing, catering services, and unit meals, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea dregs, bones, etc. The main sources are home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. Kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce bad smell. After proper treatment and processing, it can be transformed into new resources. The high organic matter content makes it possible to be used as fertilizer and feed after strict treatment, and can also produce biogas for fuel or power generation. The oi...
