Plastic fiber cultivating soil and preparation method thereof

Abstract

Plastic fiber cultivating soil is prepared from 15-35% of foundation soil, 5-35% of plant fiber powder, 10-50% of perlite, 5-15% of peat soil and 5-15% of dual-component hot-melt adhesion composite fibers. The composite fibers are formed by compositing two thermoplastic polymers through composite spinning according to a sheath-core type structural mode. The difference of melting points of the adopted two thermoplastic polymers is not lower than 30 DEG C. The composite fibers are composed of dual-component hot-melt adhesion composite fibers A with the particle size being 15-25 mm and dual-component hot-melt adhesion composite fibers B with the particle size being 3-8 mm. The composite fibers A and the composite fibers B can be made of same materials or different materials. The particle size of the plant fiber powder is 0.2-0.9 mm. The plastic fiber cultivating soil has the advantages that the cultivating soil can be cured and formed and is long in service life, not prone to weathering, low in weight, high in moisture-preserving performance and breathability, capable of being recycled after being discarded and the like. The plastic fiber cultivating soil has the main effects that the problems that in the vertical greening construction process, plants cannot be easily attached to walls, planting soil is large in gravity, and the soil is not easily shaped and is prone to dispersion are solved, and the problem that large-scale mechanical seedling inserting is difficult in upland soil planting. Due to the fact that most raw materials come from agricultural and forestry waste, a contribution can be made to agriculture and environmental protection, and the fiber soil can be recycled or directly used as combustion improver after being used.

Description

technical field [0001] The invention relates to the fields of agriculture, forestry, environment and ecological restoration, and is soil for plant growth. Background technique: [0002] In recent years, the smog has been severe, and a large number of waste resources in rural areas have been idle. In order to promote greening and protect the environment, large and medium-sized cities have begun to do greening on roofs, roofs, artificial slopes, high-rise walls and other windy and windy places. When greening roofs, artificial slopes, etc., the more common method is to fill plastic trays with soil or wrap them with non-woven fabrics, and then put the whole plant on the roof and artificial slopes together with bags. However, after such construction, the force on the base is very heavy, and the water and soil in the small container are easy to lose, and the drainage performance is not good. In heavy rain, it is easy to harden, and in fine weather, dust is everywhere. Therefore,...

Problems solved by technology

These original technologies have reduced the damage to the root pot to a certain extent, but the effect is not very good, because the peritoneal technology requires high work, and the self-degradation of the pot takes time, etc.
