Problems solved by technology

However, there are problems such as long fermentation period, high cost and low fertilizer efficiency in the composting production process.
For example, Chinese patent CN99111417.5 discloses an aerobic composting process for organic waste. It is a process in which fly ash is added as a high-temperature aerobic accelerator. Through the biological metabolism of aerobic microorganisms, the organic waste Organic matters are converted into organic fertilizers, wastes are utilized, and the environment is purified. At the same time, due to the addition of fly ash, the shortcomings of sticky materials and poor ventilation are overcome, but the quality of compost products produced by this inventive process is low; as disclosed in Chinese patent CN102617196 A method for quick composting of grass clippings is proposed. Firstly, EM compound bacterial agent is added to the crushed grass clippings. After being fully mixed, high-temperature aerobic fermentation is carried out. The fermentation device is stacked and manually turned; Fermentation temperature reaches 50-80°C, maintain this temperature for at least 8 days, and after C / N drops below 20, composting ends
Although the present invention solves the problem of excessive storage of grass clippings and taking up a large space during the period of vigorous lawn growth, the invention is only aimed at grass clippings, and the quality of compost products has not been greatly improved

Abstract

The invention discloses a garden plant waste composting method. The method comprises the following steps: (1) collecting garden plant wastes, and sorting the wastes; (2) trimming the branches, and the cutting the trimmed branches into pieces; (3) placing the pieces into a fermentation tank, adding a conditioning agent and EM bacterium agent, and then adjusting the organic substance content, water content, and carbon / nitrogen ratio to carry out primary compost fermentation; (4) grinding the compost to obtain compost powder; (5) placing the compost powder into the fermentation tank again, adding a compost decomposing agent and compost auxiliary materials, evenly mixing, and controlling the water content, temperature, introduced gas amount, carbon / nitrogen ratio, carbon / phosphorus ratio, and pH to carry out secondary compost fermentation; (6) stacking the secondary compost in an aging warehouse, blowing air into the warehouse to promote heat dissipation and water evaporation, and finally storing the qualified decomposed compost in a warehouse after detection. The method has the advantages of simple operation, rapid fermentation, and low production cost and is suitable for massive production in factory. Furthermore, the quality of the produced compost is high.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for composting garden plant waste. Background technique [0002] As an important element of urban landscape, green space is an important part of urban ecosystem. With the acceleration of urbanization, the area of ​​urban green space is increasing, and the resulting waste of garden plants is also increasing. Garden plant waste (pruning waste) mainly refers to the plant residues produced by the natural fall of garden plants or artificial pruning, mainly including branches, leaves, grass clippings, etc., and some researchers call it landscaping waste, greening waste, Garden waste, green plant waste, garden organic waste, garden waste, green waste, etc., its main component is lignocellulose. According to data from the China Statistical Yearbook, from 2008 to 2012, the area of ​​urban gardens and green spaces in my country basically showed an upward trend. At...
