Problems solved by technology

[0010] (1) The fertility of the fertilizer is difficult to control, causing the plants to grow too fast, quickly consuming the matrix nutrients, causing the plants to die due to lack of nutrients, shortening the service life of the entire module, and frequent replacement;
[0011] (2) The soft substrate is not convenient for modular fixing and installation, and the water retention effect is not good. The plant root system grows too fast and quickly consumes the nutrients of the substrate, resulting in a shorter service life of the entire module.

Abstract

The invention provides a plant growth solid medium prepared from Chinese fir sawdust as the main ingredient; the Chinese fir sawdust can be pulped under heating and adhered mutually without any extrabinders so as to form the solid medium in a compressed block shape; the solid medium is convenient to be carried and mounted in a modular mode, has a certain inhibiting effect to growth of the plant root system, and has longer service life. Besides, the Chinese fir sawdust ferments slowly during use and releases nutrient components slowly, and thus growth speed of plants can be controlled while service life of the solid medium can be prolonged. Adding of powdered carbon has effect of inhibiting mould and disinfecting. Usage proportion and grain size of Chinese fir sawdust and powdered carbon are controlled so that the solid medium keeps a proper water-retention rate, good breathability is guaranteed while enough moisture can be supplied for growth of plants. Fermentation speed is reduced by adding of an inhibitor, the nutrient components are released slowly, and accordingly growth speed of plants can be controlled while service life of the solid medium can be prolonged.

Description

technical field [0001] The invention relates to the field of plant growth substrates, in particular to a plant growth solid substrate and a preparation method. Background technique [0002] Wall greening is also called vertical greening and three-dimensional greening. Due to the limited land in the city, it is necessary to make full use of the space and plant various plants or high-climbing vines on walls, balconies, window sills, roofs, scaffolding, etc. [0003] The existing wall greening mainly adopts the following planting forms: [0004] (1) Skeleton + flowerpot, usually close to the wall or 5-10cm away from the wall to build a skeleton parallel to the wall, supplemented by drip irrigation or sprinkler irrigation system, and then insert the pre-greened flowerpot into the skeleton space; [0005] (2) Modular wall greening, its construction process is similar to that of the skeleton + flowerpot waterproof, but the improvement is that the flowerpot has become a geometric...
