Problems solved by technology

However, the water retention and permeability of the planting matrix and its own weight are contradictory. Good water retention will inevitably lead to poor water permeability and heavy weight. Therefore, in the prior art, more attention is paid to water permeability and light weight when producing and processing implants qualitative research, few people pay attention to the water retention of the planting substrate

Abstract

The invention belongs to the technical field of greening engineering, and particularly relates to a production method of a light water-retaining implant for three-dimensional greening. The production method comprises the following nine steps that a nutrient medium is selected, the nutrient medium is dried, the nutrient medium is screened, metering is achieved, mixing is achieved at normal temperature, thermally mixing is achieved, forming is achieved, demoulding and punching are achieved. According to the production method of the light water-retaining implant for three-dimensional greening, all the components in materials are uniformly mixed through normal-temperature mixing, and then the materials are softened under the action of hot air, so that compression molding is easier. The hot air obtained after hot mixing is used for drying the medium, heat is fully utilized, the effect of saving energy is achieved, and the production and processing cost is further reduced. The implant produced by the production method can be widely applied to greening of urban roads, squares, residential quarters, side slopes and the like, is high in material breathability and water absorption and retaining rate, and is easy for plant growth and root development.

Description

technical field [0001] The invention belongs to the technical field of greening engineering, and in particular relates to a production method of a lightweight water-retaining implant used for three-dimensional greening. Background technique [0002] With the acceleration of the urbanization process, high-rise buildings are everywhere, and a large number of cement buildings are pouring into the city. The urban heat island effect is more obvious. In order to increase the green area, the city has a stronger demand for soil. However, fertile topsoil resources in cities are becoming more and more scarce, and pure soil cannot meet the requirements of roof greening and wall greening projects. Therefore, people continue to explore the most cost-effective artificial cultivation soil for urban greening. [0003] Three-dimensional greening refers to the regeneration space formed by all buildings and structures, using various means in modern gardens and buildings to carry out multi-form...
