The invention provides the preparation and application of a water-retaining and temperature-regulating material for forage planting in wind-eroded pits. The material is prepared by compounding at least two organic phase change energy storage materials at high temperature to obtain a eutectic, then mixing the eutectic with a polymer water-retaining material, adding tap water and stirring evenly, and adding the material to the Mix the mixture of soil, sand, sheep manure and forage seeds, put it into sacks, and put it into the wind erosion pit. In the present invention, at least two kinds of organic phase-change energy storage materials are used for high-temperature compounding to obtain a eutectic, which is used to slow down the sudden drop of the ambient temperature, so as to achieve the purpose of adjusting the temperature and provide suitable temperature for the germination and growth of forage grass, and then The eutectic compounded by the organic phase change energy storage material and the polymer water-retaining material are mixed to obtain a water-retaining and temperature-regulating material connected by hydrogen bonds, and the eutectic compounded by the organic phase-change energy storage material and the polymer water-retaining material are coordinated with each other , working together, the material has excellent water retention and temperature regulation performance. |
