Greening plant waste organic medium as well as preparation method and application thereof

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...

Problems solved by technology

However, the soil used for the roof garden cannot use raw fertilizer, otherwise it will attract flies, ants or small insects

[0005] In the process of urbanization, reinforced concrete is an indispensable construction, resulting in high salinity in the soil, and the soil in the Yangtze River Delta is mainly clay. After long-term use of chemical fertilizers, the soil has poor air permeability and water permeability, and is easy to harden. Planting that is not conducive to greening
