Abstract

The invention provides a light three-dimensional greening water-retaining substrate, and belongs to the technical field of garden agriculture. The light three-dimensional greening water-retaining substrate comprises components in parts by weight as follows: 20-35 parts of turfy soil, 5-10 parts of a water-retaining agent, 8-12 parts of compost sludge, 4-8 parts of perlite, 4-8 parts of vermiculite, 5-10 parts of activated carbon, 6-10 parts of a slow release fertilizer and 1-10 parts of an auxiliary agent, wherein the water-retaining agent is a water-absorbing gel material, and the auxiliary agent is one or more of a growth regulator, an antibacterial agent and a pH regulator. The water-retaining substrate has good water-retaining property and lower specific gravity, and water loss is greatly reduced by utilizing good water absorption and water retention performance of the water-absorbing gel material.

Description

technical field [0001] The invention relates to the technical field of garden agronomy, in particular to a preparation method and application of a lightweight three-dimensional greening and water-retaining substrate. Background technique [0002] Three-dimensional greening is the general term for ground greening, wall greening, and roof greening. It is a way of greening in three-dimensional space corresponding to ground greening. Climbing plants are planted in other places to increase green coverage and improve the living environment. Three-dimensional greening has the advantages of less land occupation, large covering area, low cost and quick results. Three-dimensional greening can not only supplement the deficiencies of flat land greening and family greening, but also enrich the level of greening, and also help restore ecological balance and improve bad environments. It is more harmonious and unified with the environment. [0003] With the rapid development of urbanizati...
