Abstract

The invention relates to a polymer aggregation agent for high order aggregate spray seeding greening, and a preparation method thereof. The polymer aggregation agent is prepared from the following materials by weight proportion: 2-4 parts of soluble polymer nanofiber, 1-2 parts of loose modifier, 2-4 parts of polymer agglutinant and 2-4 parts of modified soil stabilizer. The polymer aggregation agent provided by the invention is simple in preparation method, the raw material is cheap and easy to get; the soluble polymer nanofiber in the raw material plays a role in forming the aggregates and connecting the soil structure, the loose modifier can increase the nutrient in the soil after aggregation, retain water, preserve moisture and keep soil soft, the polymer agglutinant can separate redundant moisture in the mud soil, and the modified soil stabilizer can stabilize the aggregate structure for long time, keep soil permeable and make soil resistant to rain wash. The polymer aggregation agent for high order aggregate spray seeding greening, provided by the invention, can make the soil keep better aggregate structure, and can be generalized and used in the fields of mine reforestation, municipal construction, ecological restoration of damaged mountains, and the like.

Description

Technical field [0001] The invention belongs to the technical field of agglomerates, and specifically relates to a polymer agglomerate agent for high-order agglomerate spraying and greening and a preparation method thereof. Background technique [0002] 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. The planting soil, fertilizer, water-retaining agent, adhesive, The mud composed of seeds is sprayed onto the rock or soil slope to form a guest soil layer, where plants germinate and grow to form a vegetation covering the slope to achieve a greening effect. If only spraying mud, the guest soil layer on the slope is prone to compaction and cracking, which is not resistant to rain erosion, slow growth of plants, unsuitable for the growth of trees and shrubs, easy degradation of grasses, serious soil waste, impermeable soil, poor water and...
