Planting soil water retaining agent for slope greening ecological restoration and preparation method thereof

Abstract

The invention relates to a planting soil water retaining agent for slope greening ecological restoration and a preparation method thereof. The water retaining agent is environmentally friendly, free of toxicity, wide in raw material source, low in cost, simple and feasible in process, capable of reducing soil moisture loss significantly, high in storage and water retention capacity, good in salt absorption effect, excellent in degradation performance and free of pollution. Zeolite has increased internal surface area, strong adsorption and enhanced colloidal property after subject to acidification, and can effectively adsorb heavy metals and radioactive wastes in the soil; guar gum is alkalized to facilitate subsequent cross-linking reaction; humic acid can improve the fertility of the soiland promote the growth of plants on the soil to achieve the effect of ecological restoration and greening; the sodium carbonate not only acts as a porogen to improve the porous structure of a copolymer, but also increases the pH of a system and increases sodium ions in the system, and the polymerization and graft ratio between the humic acid and acrylic acid, acrylamide, vegetable fiber and starch is increased.

Description

technical field [0001] The invention belongs to the technical field of slope greening, and relates to a plant soil water-retaining agent for ecological restoration of slope greening and a preparation method thereof. Background technique [0002] Slope greening is a new ecological slope protection method that can effectively protect exposed slopes. It is combined with traditional civil engineering slope protection (reinforced anchor bolt support, hanging net, lattice, etc.) to effectively realize the ecological protection of the slope. Vegetation restoration and protection not only have the function of water and soil conservation, but also can improve the environment and landscape, and improve the level of health care and culture. Slope greening is mainly divided into: steep slope greening and gentle slope greening; earthy slope greening and stone slope greening. [0003] With the rapid development of economy and society, China's basic construction speed is accelerated, and ...

AI Technical Summary

Problems solved by technology

[0005] Soil water-retaining agents used for slope greening restoration in the prior art include three types: synthetic resin, starch and plant cellulose. Among them, the synthetic resin-based water-retaining agent has high production efficiency, low cost, simple process, and good water absorption performance. , high gel strength, but its effect is relatively simple, time-consuming, insignificant, poor salt tolerance, difficult to degrade, pollute the environment, which limits its popularization and use; and starch-based water-retaining agents have a wide range of raw materials and are durable Good salinity, easy to degrade, non-toxic, environmentally friendly and pollution-free, good repeated water absorption performance, but its stability is poor, and the water absorption rate is slightly low; plant cellulose water-retaining agent has a wide range of raw materials, low cost, good salt tolerance, and good repeated water absorption performance , strong stability, non-toxic, and environmentally friendly, but the separation and purification process of its raw materials is complex, difficult, and costly
