A kind of plant soil water-retaining agent for slope greening ecological restoration and preparation method

Abstract

The invention relates to a vegetable soil water-retaining agent used for ecological restoration of slope greening and a preparation method thereof. The water-retaining agent prepared by the invention is environmentally friendly and non-toxic, has a wide source of raw materials, low cost, simple and easy process flow, significantly reduces soil moisture loss, has strong storage and water retention capabilities, good salt absorption effect, excellent degradation performance, and will not cause pollution. Green and environmentally friendly water-retaining agent; zeolite has increased internal surface area after acidification treatment, strong adsorption, and enhanced colloidal performance, which can effectively absorb heavy metals and radioactive waste in the soil; alkalization treatment of guar gum facilitates subsequent cross-linking reactions; Phylic acid can increase the fertility of the soil, promote the growth of plants on the planting soil, and achieve the effect of ecological restoration and greening; the addition of sodium carbonate not only acts as a porogen to improve the loose porous structure of the copolymer, but also increases the pH value of the system and increases the pH value of the system. Sodium ions increase the ratio of polymerization and grafting between humic acid and acrylic acid, acrylamide, plant fiber and starch.

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 ...

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
