Snow moisture sowing method for herbaceous plants on side slope of arid region

Abstract

The invention discloses an arid region slope herbaceous plant snow moisture sowing method, and belongs to the technical field of desertification prevention and control, in the complete mature period of the Tiemann and the Tiemann, capsules with full grains and good maturity on dead plants are collected, and Tiemann clean seeds and Tiemann clean seeds are obtained respectively and stored for standby application; soil of the slope surface of the side slope is prepared; the method comprises the following steps: uniformly mixing clean seeds of the gleman pitaya and clean seeds of the elaeagnus mollis to obtain mixed seeds, then mixing the mixed seeds with dry and fine sandy soil, and uniformly stirring to obtain mixed seed soil; adding clear water into the mixed seed soil to obtain wet seed soil; sowing the wet seed soil; the slope surface is covered with a straw mat and fixed; after heavy snow in winter, snow on the flat ground above the slope surface is evenly scattered on the slope surface straw mats, and light pressing and smoothing are conducted; in spring of the next year, after the grass seeds germinate, the grass mats are removed. According to the method, conditions are created for successful planting of plants on the arid region slope, so that the persistence of water and soil conservation of the arid region slope is achieved.

Description

technical field [0001] The invention relates to the technical field of desertification prevention and control, and more particularly to a method for sowing snow moisture of herbaceous plants on slopes in arid areas. Background technique [0002] In recent years, due to the large-scale construction of water diversion canals, high-grade highways and railways, it is often necessary to excavate and fill a large number of side slopes. Numerous exposed slopes commonly have scouring erosion, sand blowing erosion, soil erosion and shallow local landslides. Taking the slope of the water supply channel in Karamay as an example, the observation and research on the slope protected by engineering measures for 20 years shows that the natural restoration of the slope vegetation cannot be achieved only by the engineering concrete grid beam measures and natural restoration. Wind erosion and sandification, snowmelt water, floods, and water erosion from summer rainstorms cause soil erosion an...

Problems solved by technology

The artificial vegetation construction technology on slopes in arid areas based on the above species has the following disadvantages: 1) The grass seed sowing and planting technology based on irrigation requires a certain amount and multiple pre-irrigation to ensure the normal germination and growth of seeds

However, in many arid and semi-arid desert areas, there are no irrigation conditions in the section where the project slope crosses, and there is a lack of water in the suitable spring planting period, making it difficult to plant grass and trees artificially; 2) Sowing technology of grass and shrub species based on low irrigation conditions It does not require much irrigation, but the growth of species is slow in the early stage, and the vegetation coverage on the ground is low. During the snow melting period in spring and the heavy rain period in summer, soil erosion is serious on the slope terrain
