Embodiment 1

[0029] S1 pretreatment: Sorting and crushing the collected garden plant waste to obtain crushed waste; the carbon-nitrogen ratio of the crushed waste is 26;

[0030] S2 Compost Fermentation:

[0031] S21 first fermentation: add the crushed waste, the first nitrogen fixer, EM bacterial liquid and peat into the fermentation tank according to the mass ratio of 1000:30:3:60, and stir evenly at a stirring speed of 30r / min. The stirring time is 1 hour, and then the first fermentation is carried out. When the temperature of the heap rises to 50°C, the first fermentation is completed, and the first fermentation product is obtained; the first nitrogen fixative is magnesium hydroxide, phosphoric acid Mixture with water, the mass ratio of magnesium hydroxide, phosphoric acid and water is 1:3:29;

Abstract

The invention discloses a garden plant waste composting method. The method comprises the following steps: sorting and crushing garden plant wastes to obtain crushed wastes, adding the crushed wastes, a first nitrogen fixing agent, an EM bacterial liquid and turf into a fermentation tank according to a mass ratio of 1000: (30-50): (3-7): (60-80), carrying out primary fermentation, continuously carrying out secondary fermentation and tertiary fermentation, and carrying out secondary fermentation and tertiary fermentation. A second nitrogen fixing agent and a third nitrogen fixing agent are respectively added in the second fermentation process and the third fermentation process, ferrous sulfate is also added in the second fermentation process to adjust the pH value, and the nitrogen fixing agent, turf and other substances capable of fixing nitrogen are added in the fermentation process, and the parameter optimization of the fermentation process is combined, so that the nitrogen fixing effect is improved. The nitrogen loss rate is greatly reduced, the fermentation efficiency is improved, and the fermentation time is shortened.

Description

technical field [0001] The invention relates to the technical field of composting, in particular to a method for composting garden plant waste. Background technique [0002] Garden plant waste (pruning waste) mainly refers to the plant residues produced by the natural fall of garden plants or artificial pruning, mainly including litter (plant litter), branch trimmings, lawn trimmings, weeds, seeds and residual flowers etc., whose main component is lignocellulose. Facing the increasing amount of garden waste, how to properly and effectively dispose and reuse this resource has become an urgent problem to be solved. [0003] In the prior art, composting and fermentation methods are often used to treat garden plant waste, that is, turning garden plant waste into bio-organic fertilizer, and applying it to the soil can improve the physical structure of the soil, improve soil compaction, retain water and fertilizer, and improve soil fertility Thereby promoting the growth and deve...
