A kind of fiber cultivation soil for three-dimensional greening and its preparation method

Abstract

The invention relates to a fiber culture soil for three-dimensional greening and a preparation method thereof. Its components include short fibers, plant fiber particles, peat soil, and pastoral soil, and the parts by weight of each component are 8 to 28 parts of short fibers, plant 10-60 parts of fiber particles, 0-30 parts of peat soil, and 10-60 parts of pastoral soil. Take its components according to the above ratio, and make high-tenacity fiber culture soil after mixing, humidifying, compacting and repeated needling. The preparation is simple, the cost is low, and the water retention and air permeability of the culture soil are good, which is beneficial to the growth of green plants. Moreover, the fiber culture soil has wide application range and strong adaptability, is extremely suitable for three-dimensional greening, and is beneficial to improving environmental pollution and increasing the green coverage rate of cities.

Description

technical field [0001] The invention relates to the field of greening, in particular to a fiber culture soil for three-dimensional greening and a preparation method thereof. Background technique [0002] Urban greening can alleviate the increasingly serious urban heat island effect and noise pollution, and the higher the coverage rate of greening, the better the urban environment will be improved. In order to improve the green coverage rate of the city, more and more attention has been paid to three-dimensional greening in various aspects such as wall greening, roof greening and viaduct greening. [0003] At present, traditional methods such as plastic boxes and cloth bags are mostly used to hold the soil for planting green plants, and the greening on the three-dimensional wall or roof is realized by fixing the plastic boxes or cloth bags. However, the drainage and air permeability of plastic boxes or cloth bags are poor, and the soil is easy to form lumps, which is not con...

AI Technical Summary

Problems solved by technology

This method not only has a high production cost for the base soil, but also has poor toughness. The base soil will crack or even break when bent more than 30 degrees. The application range of the base soil is narrow, and the cracked or broken base soil cannot be repaired on site, resulting in waste of soil

At the same time, high-temperature heating treatment will also increase the energy consumption of the production of base soil, which is not conducive to energy-saving production
