The invention relates to the field of applications of biomass materials to crop planting, in particular to a corn seed coating agent with root strengthening, seedling strengthening and water retention functions and a preparation method of the corn seed coating agent. The coating agent comprises polyaspartic acid, a crosslinking agent and xanthoceras sorbifolia bunge shell flour, wherein the weight ratio of polyaspartic acid to the crosslinking agent is 200: (1-6), and the proportion of xanthoceras sorbifolia bunge shell flour to polyaspartic acid is 1: (15-45). By means of the obtained corn seed coating agent, corn seeds planted in the soil under the arid and semiarid climate conditions can obtain more sufficient water and nutrients, the seed germination rate is guaranteed, growth at the corn seedling stage is promoted, and stress tolerance of corn is increased. With adoption of the method, the cost is low, and the operation is simple and convenient.

The invention discloses slope-greening eco-concrete and a preparation method thereof and relates to the slope-greening field. The slope-greening eco-concrete comprises the following ingredients: 1200-1300 parts of coarse sand, 200-250 parts of pottery sand, 70-100 parts of cement, 25-50 parts of sodium carboxymethylcellulose, 20-30 parts of sodium silicate, 3-5 parts of calcium superphosphate, 2-3 parts of vermiculite, 2-3 parts of perlite, 5-10 parts of turfy soil and 160-200 parts of water. The preparation method comprises the following steps: preparing the raw materials; throwing coarse sand, pottery sand, cement, vermiculite and perlite into a first blender to be blended; throwing sodium carboxymethylcellulose, calcium superphosphate and water into a second blender to be blended; throwing the material in the second blender into a first blender to be blended; throwing turfy soil into the first blender to be blended to obtain the slope-greening eco-concrete. The slope-greening eco-concrete is strong in adhesion, high in strength, low in cement consumption and suitable for plant survival.

The invention discloses a device for greening and circularly supplying moisture and nutriment for vegetation on a rock slope and a construction method. The device comprises the rock slope, wherein anchor rods are anchored on the rock slope through bolt-shotcrete supports, the anchor head position of each anchor rod is lengthened and provided with a bearing platform, the bearing platforms are provided with water tanks correspondingly, and vegetation growth devices are arranged at the tops of the water tanks correspondingly; a reservoir is arranged at the top of the rock slope, the reservoir isconnected with the water tanks through PVC hoses, and the PVC hoses are provided with water valves correspondingly; and flared openings are formed in the outer walls of the bearing platforms correspondingly. According to the construction method, lawn nursery strips are laid on the slope surface of the exposed rock slope by utilizing the climbing or hanging growth habits of climbing plants, meanwhile, the reservoir arranged at the top of the slope and the water tanks arranged on the slope surface form a water circulation system, and a nutrient circulating system is formed by the bearing platforms used for recycling the plant nutrients, so that on one hand, the slope can be rapidly covered and greened by the vegetation, and on the other hand, a long-term stable vegetation greening can be achieved.

The invention discloses a method for governing deserts by utilizing vegetal modified sand. The vegetal modified sand is paved on the surface of a desert to be governed, and is formed by dissolving a water-soluble solid organic matter in water to form a cohesive and adhesive solution, and mixing the cohesive and adhesive solution with plant seeds and sand; after moisture evaporates, the water-soluble solid organic matter can bond sand, and can be dissolved in water again after meeting water to form the cohesive and adhesive solution to bond sand. According to the invention, common sand can serve as soil; the interaction among sand grains is changed fundamentally; a particle pore structure with binding force (sticking force) is formed; materials cannot run off easily due to the cohesive and adhesive properties; the vegetal modified sand can be as stable as soil, and can store water and nutrients as soil; plants can grow directly after the vegetal modified sand is mixed with the plant seeds. Therefore, the method provides a solid condition for tree growth, and is an ideal desert governing measure.

The invention discloses nutrient modified sandy soil for planting. The nutrient modified sandy is formed by dissolving a solid organic substance, which can be dissolved in water to form a solution with cohesiveness and adhesivity and then blending the solution with sandy soil and nutrient; the solution can be adhered to sandy soil particles after being blended with sandy soil, and formed modified sand adopts a particle pore structure; after water is evaporated, the solid substance is adhered to the sandy soil particles, and is dissolved in water again when meeting water and is adhered to the sandy soil particles. The nutrient modified sandy soil ensures that general sandy soil forms soil, and thoroughly changes the interaction relation among sandy soil particles, and forms particle pore structures with bonding force (cohesive force); the modified sandy soil is difficult to run away when in use because of the characteristics of cohesiveness and adhesivity; the modified sandy soil is enabled to be as stable as soil and have water and nutrient storage performances, is directly added to nutrient for plant growth, and belongs an ideal desertification control measure; the modified sandy oil can also serve as a measure for utilizing sand resources, such as sand beach, so as to perform planting.
