Macromolecular aggregate plant growth substrate and preparation method thereof

Abstract

The invention discloses a macromolecular aggregate plant growth substrate used for restoring vegetation, spray seeding and greening and a preparation method thereof. The macromolecular aggregate plant growth substrate is formed by mixing water, plant growth soil, a humification material, a fiber material, a fertilizer, a soil control conditioning agent, a macromolecular soil stabilizer, a macromolecular aggregate agent, macromolecular aggregate agent dissolution water and seeds. Compared with the prior art, the macromolecular aggregate plant growth substrate has the advantages that the macromolecular soil stabilizer and the soil control conditioning agent are added, a soft soil structure can be maintained for a long time, permeability of soil is guaranteed, the soil is resistant to rain wash, moisture and fertility are preserved, the soil is effectively avoided hardening and coking, kinds and dosages of raw materials can be independently selected according to a construction environment, and plant growth substrates with different soil properties can be prepared, so that growth requirement of different kinds of plants can be met.

Description

technical field [0001] The invention belongs to the field of plant growth substrates, and in particular relates to a macromolecule aggregate plant growth substrate which can be used for vegetation restoration spraying and greening and a preparation method thereof. Background technique [0002] The exposed slopes of railways, highways, dams, mines, saline-alkali land, etc. caused by various reasons have attracted people's attention to the adverse impact on the environment. Particulate matter affects human health, and if it is not treated for a long time, it will gradually lead to climate change and threaten the human living environment. [0003] In order to protect the exposed slopes of railways, highways, dams, etc., and maintain ecological balance, the slopes are often greened. At present, the method of spraying greening is widely used, and planting soil, fertilizers, water-retaining agents, adhesives, The plant growth substrate composed of seeds etc. is sprayed onto the r...

AI Technical Summary

Problems solved by technology

Although the plant growth substrate in the prior art can make the slope form vegetation in a short period of time to achieve the effect of regreening, the guest soil layer on the slope is prone to compaction and cracking, which is not resistant to rainwater erosion, and the plants grow slowly, which is not suitable for the growth of trees and shrubs. , the grass planting is easy to degrade, the soil waste is serious, the soil is airtight, and the ability to retain water and fertilizer is poor
