Embodiment 1

[0025] Send the waste of tree branch pruning in greening into the grinder continuously, crush it to a length of 3-8cm at a time, and then finely crush it again to a fine powder with a length of 0.5-1.5cm; then discard the green plants in the powdery shape The waste is placed in a sealed greenhouse fermentation shed, and the carbon-nitrogen ratio of the waste is controlled to 25:1-35:1. A little inorganic nitrogen fertilizer such as urea can be added to regulate.

[0026] After adjusting the carbon-nitrogen ratio, add fermented water containing Bacillus, Trichoderma, and EM bacteria strains, and ferment the fermented mixture in a closed environment at a temperature of 55-65°C; during the fermentation process, the water content of green plant waste is 40 -55%, ferment for 14-20 days to form a fermented organic medium; the slag water collected in the drainage tank is recycled as fermented water.

[0027] The content of Bacillus, Trichoderma, and EM strains in dregs water is less...

Abstract

The invention belongs to the technical field of soil improvement and particularly relates to a preparation method and application of a greening plant waste organic medium capable of realizing soil remediation. The preparation method comprises the following steps: performing crude crushing and fine crushing on greening plant wastes to form powder with the length of 0.5-1.5cm; then putting the powdery greening plant wastes in a closed greenhouse for fermentation, controlling the carbon-nitrogen ratio of the wastes to (25:1)-(35:1), and then blending fermentation water containing bacillus, trichoderma and EM (effective microorganism) bacteria for mixing; controlling a fermentation mixture in a closed environment at the temperature of 50-65 DEG C for fermentation; and fermenting the greening plant wastes with the water content of 40-55% in fermentation process for 14-20 days to form the fermentation organic medium. The organic medium and raw soil are mixed according to a certain proportion. The mixed soil has the advantages of light weight, good bulkiness, porosity and water permeability, high content of organic matters and rich nutrients and is suitable for application in urban greening soil improvement and exhibition greenhouse and roof greening.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to an organic medium of greening plant waste and its preparation method and application. Background technique [0002] During the growth of urban greening plants, plant waste materials such as litter and leaves produced by natural regeneration or tree and shrub trimmings, lawn trimmings, discarded grass flowers and weeds produced in the process of greening maintenance become garbage. Handling is often a big problem. [0003] At present, there are several traditional treatment methods for greening plant waste, some are composted as organic matrix, used as mulch to improve and repair soil, and some are incinerated or landfilled. However, with the increasing requirements of urban greening environment and the continuous increase of urban greening rate, there is an increasing problem of disposal of greening plant waste. If the traditional incineration or landfill m...
