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 f...

Embodiment 1

[0020] A method for preparing organic fertilizer from organic waste produced by vegetables, comprising the following steps:

[0021] a. Material mixing: Cut 1000Kg of vegetable straw waste from plastic and stone debris into 20 cm below with a hay cutter, pour it into the mixing tank, add 300Kg of cow and sheep manure, 100 kg of phosphate rock powder, wheat rice 50 kg of stone powder, stir evenly, adjust the water content to 58%, C / N = 25:1, pile up for 3 days;

[0022] b. Aerobic fermentation: stack the heat-generating mixed materials that have been stacked for 3 days in the fermentation tank and use a trough-type turning machine for turning and throwing treatment. When the temperature rises to 60°C, turn the pile and control the temperature at 62°C. The oxygen fermentation cycle is 5 days;

[0023] c. Secondary fermentation: After aerobic fermentation, use a sieve to sieve. The unfermented cellulose lignin on the sieve enters the carbonization furnace for anaerobic carboniza...

Embodiment 2

[0027] A kind of method that utilizes the organic waste that fruit tree produces to prepare organic fertilizer, comprises the following steps:

[0028] a. Material mixing: Use a sawdust grinder to grind 1000Kg of fruit tree pruning waste from plastic and stone debris into a size below 5 cm, pour it into a mixing tank, add 350Kg of cattle and sheep manure, 150 kg of phosphate rock powder, and stir Evenly, adjust the water content to 53%, C / N = 28:1, stack for 4 days;

[0029] b. Aerobic fermentation: Mix and stack the heat-generating mixed materials that have been piled up for 4 days in the fermentation tank, use a tank-type turning machine to turn over the mixed materials in the fermentation tank, and start turning when the temperature rises to 62°C Heap, control temperature at 65°C, aerobic fermentation cycle 6 days;

[0030] c. Secondary fermentation: After aerobic fermentation, sieve with a sieve, and the unfermented cellulose lignin on the sieve enters the carbonization f...

Embodiment 3

[0034] A method for preparing organic fertilizer from organic waste produced by fruit trees and vegetables, comprising the following steps:

[0035] a. Material mixing: Cut 500Kg of vegetable straw waste from plastic and stone debris into less than 20cm with a hay cutter, and crush 500Kg of fruit tree pruning waste into less than 5cm with a sawdust grinder, pour it into the mixture and stir In the tank, add 350Kg of cattle and sheep manure, 150 kg of phosphate rock powder, stir evenly, adjust the water content to 60%, C / N = 30:1, and pile up for 5 days;

[0036] b. Aerobic fermentation: stack the heated mixed materials that have been piled up for 5 days in the fermentation tank, and use the trough-type turning machine to turn over the mixed materials in the fermentation tank, and start turning when the temperature rises to 65°C , the temperature is controlled at 70°C, and the aerobic fermentation cycle is 5 days;

[0037] c. Secondary fermentation: After aerobic fermentation,...

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...
