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...

Examples

Embodiment Construction

[0007] In the autumn of 2009, the dead branches and leaves and trimmed lawn grasses were collected from the green belt on the outer ring road in Tianjin, and they were piled up in the organic fertilizer factory. The volume is 70 cubic meters, and 30 cubic meters of raw cow dung is purchased from Tangshan cattle farm. The volume ratio of litter and cow dung is 7:3, and the mixer is mixed evenly. After stacking for 15 days and decomposing, the above-mentioned organic fertilizer is applied to the base fertilizer for landscaping, and the survival rate of the seedlings reaches 90% on average, and the growth is good.
