Method of utilizing organic waste produced by fruit trees and vegetables to prepare organic fertilizer

Abstract

The invention discloses a method of utilizing organic waste produced by fruit trees and vegetables to prepare organic fertilizer. The method includes following steps: a, mixing materials, and stacking for anaerobic fermentation; b, performing aerobic fermentation; c, secondary fermentation: screening, subjecting an oversize product to biomass carbonization, and mixing with undersize organic fertilizer for fermentation; d, grinding and screening; e, detecting and packing. The organic waste like one or multiple fruit tree trimmed branches and vegetable vines is utilized as a main material of the organic fertilizer, so that the waste is treated effectively; by performing low-temperature carbonizing treatment on non-rotten rich cellulose, adsorption and ventilation functions of the organic fertilizer are improved, quality of the organic fertilizer is improved, fermentation period is shortened, production efficiency is improved, harmless recycling of the organic waste like the fruit tree trimmed branches and the vegetable vines produced by the fruit trees and the vegetables is realized, and requirements of cyclic economy on comprehensive resource utilization are further met.

Description

technical field [0001] The invention relates to the fields of organic waste treatment and organic fertilizer production produced by fruit trees and vegetables, in particular to a method for preparing organic fertilizers from organic waste produced by fruit trees and vegetables. Background technique [0002] With the increase of fruit and vegetable production area, especially the development of greenhouse vegetable industrialization and deep processing, vegetable waste is increasing day by day. Now the national vegetable waste is as high as 200 million tons per year, resulting in fruit tree pruning, vegetable vines, seedlings, etc. More and more organic wastes such as vines and vines are produced, because most of them contain harmful bacteria and insect eggs and cannot be returned to the field for use. Most of them are burned or discarded near the farmland and in gullies and channels. environmental pollution problems. Because vegetable vines and seedlings are rich in cellulo...

Problems solved by technology

[0002] With the increase of fruit and vegetable production area, especially the development of greenhouse vegetable industrialization and deep processing, vegetable waste is increasing day by day. Now the national vegetable waste is as high as 200 million tons per year, resulting in fruit tree pruning, vegetable vines, seedlings, etc. More and more organic wastes such as vines and vines are produced, because most of them contain harmful bacteria and insect eggs and cannot be returned to the field for use. Most of them are burned or discarded near the farmland and in gullies and channels. environmental pollution problems

Because vegetable vines and seedlings are rich in cellulose and are not easy to decompose, mixed fermentation with livestock and poultry manure often results in the failure of humification of cellulose, a lot of return materials, and high production costs. At present, the existing domestic bio-organic fertilizer technologies are all used Livestock and poultry manure, grain straw and fungal residues containing lignin and less cellulose limit the recycling of organic waste to a certain extent
