Method for decomposing and fermenting garden dry branches and fallen leaves into organic fertilizer

Abstract

The invention relates to a method for decomposing and fermenting garden dry branches and fallen leaves into an organic fertilizer, aiming at piling and fermenting the dry branches and fallen leaves to be converted into the organic fertilizer. The method comprises the following steps: collecting the dry branches and fallen leaves of garden plants from thick green areas in autumn, such as a road green space and a park; cutting and crushing the collected dry branches; mixing with the collected fallen leaves; adding raw cattle excrements to the mixture of the dry branches and fallen leaves in order to enhance the fertility of the organic fertilizer; mechanically agitating; uniformly mixing; adding a fermentation bacteria agent; and finally piling, decomposing and fermenting. By adopting the organic fertilizer production method, the waste in a garden can be converted into the organic fertilizer; moreover, the cost is low, the operation is simple, the prepared organic fertilizer is high in nutrient content, the physicochemical properties of soil can be improved well, and the pollution of the garden waste to environment can be reduced effectively.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, in particular to the field of producing organic fertilizers from garden wastes. Background technique [0002] With the rapid development of urban afforestation, urban green space expands rapidly, and the physiological product of plants-litter (litter) is produced in large quantities. The traditional concept often thinks that litter and leaves affect sanitation and landscape, so a lot of manpower and funds are spent every year to clean and burn them, which puts a lot of pressure on green space maintenance management and city appearance and environmental management. [0003] At present, there are three main methods for dealing with litter in main landscaping areas: sanitary landfill, incineration and traditional method of composting, but these methods have certain limitations: 1. The landfill operation is simple, but covers a large area , and may cause secondary pollution; 2. The investment in i...

Problems solved by technology

[0003] At present, there are three main treatment methods for the litter in the main landscaping areas: sanitary landfill, incineration and composting by traditional methods, but these methods have certain limitations: 1. The landfill operation is simple, but covers a large area , and may produce secondary pollution; 2. The investment in incineration is huge, and incineration will cause smoke pollution problems; 3. The traditional composting method is easy to generate odor and pollute the surrounding environment. At the same time, the methane produced by the fermentation of leaves will become a fire and the hidden danger of explosion, and the emission into the atmosphere will cause the greenhouse effect

[0004] The purpose of the present invention is to provide a method for fermenting and fermenting litter in gardens into organic fertilizer, which avoids the disadvantages of air pollution caused by traditional composting, instead of simply fermenting litter into organic fertilizer, adding cattle in a certain amount when decomposing Feces and fermenting agents, reducing the hazards of litter composting
