Spray-seeding grass planting construction method for side slope of high-altitude area

The invention discloses a high-altitude area side slope spray-seeding grass planting construction method. The method comprises the steps that a slope surface is cleaned, and soil is loosened; laying a net; paving stones; anchor rods are installed; performing multi-layer spray seeding; covering a non-woven fabric; and performing subsequent maintenance. The high-altitude area side slope spray-seeding grass planting construction method is mainly suitable for a stable cutting side slope with the side slope ratio being 1: 0.75 or 1: 0.5 and the single-stage side slope height being smaller than 10 m. According to the slope spray-seeding grass planting construction method, a multi-layer spray-seeding mode is adopted, matrix spray-seeding is conducted on the lower layer firstly, grass seed mixture spray-seeding is conducted on the upper layer after soaking is conducted, perennial ryegrass, trifolium repens, sophora davidii and willow orchid which are more suitable for growing in high-altitude areas are selected as gr
