Sludge improved base material for slope greening and preparation method thereof

Abstract

The invention discloses a sludge improved base material for slope greening and a preparation method thereof. The base material comprises the following components: sludge, peat soil, loess, rice husk fibers, cement, mycorrhiza, a water-retaining agent, an adhesive, a compound fertilizer and a microbial starter. Due to the fact that the sludge is improved into the available slope greening base material, the environment is improved, and waste is turned into wealth. Most of the base materials used in the method come from sludge, local mountainous area loess and common peat soil, and compared withspecial planting soil, the manufacturing cost is greatly reduced. The cement is added to enhance the scouring resistance and shear strength of the base material. The rice husk fibers are added, so that soil can be loosened, a large number of trace elements are contained, growth of plants can be better facilitated through fermentation, and a good growth environment is provided for the plants. The microbial leavening agent is added, a large number of beneficial substances easy to absorb by plants can be generated, and healthy growth of the plants is achieved.

Description

technical field [0001] The invention relates to geotechnical engineering, ecological restoration technology and agriculture and forestry science, in particular to a sludge improvement base material for slope greening and a preparation method thereof. Background technique [0002] Nowadays, with the continuous increase of urban population, the problem of urban sewage treatment is becoming more and more important. The terminal sludge treated by the sewage treatment plant in the city contains relatively rich organic matter, which can play a certain role in improving soil fertility, but its own water retention capacity is too poor, and the heavy metal content seriously exceeds the standard. If it is directly used as slope protection foundation wood, not suitable for plant growth. Therefore, there is a need for a method that can improve urban sludge, making it an available new substrate for sludge improvement, so that slope protection plants can grow well, and achieve the goals ...
