Vegetation particle for high and cold meadows and method for preparing vegetation particle

Abstract

The invention provides a vegetation particle for high and cold meadows, and relates to the field of ecological restoration of grasslands. The vegetation particle is heavier than 0.8 g, and the porosity of the vegetation particle is 45%-50%. The vegetation particle comprises diversified pretreated grass seeds, substrate nutrition layers and water retention layers. The substrate nutrition layers wrap the surfaces of the grass seeds; the water retention layers are positioned between the grass seeds and the substrate nutrition layers. The vegetation particle has the advantages that the technical problems of difficulty in sowing seeds in high and clod grassland regions, high destructiveness, weak material selection pertinence of pelleting processes and the like can be solved by grass seed pelleting processes; the drifting properties of the seeds can be effectively lowered, the seed landing stability can be improved, the seed sowing accuracy can be enhanced, the germination percentage of the seeds can be increased, and the vegetation particle is suitable for near-natural reseeding restoration of high and cold grasslands.

Description

technical field [0001] The field of grassland ecology of the present invention, especially the plant life grain for alpine grassland. Background technique [0002] Alpine grassland is a vegetation type of grassland community. It is generally above 4,000 meters above sea level. Its climate is characterized by low temperature, large temperature difference, little precipitation, long sunshine, strong wind, many sandstorms, long cold season and dry cold, warm season. Short and cool. However, most of the alpine grassland grass seeds have small and light seeds. Therefore, when weeding grass seeds on the plateau, we should ensure that the seeds are in full contact with the soil and have sufficient water, otherwise the seeds are not easy to germinate. However, the ecology of the alpine grassland is fragile, and excessive farming measures will easily lead to the destruction of its habitat and ecological deterioration. Therefore, it is not suitable to have too many farming measures o...

AI Technical Summary

Problems solved by technology

[0006] The invention aims to solve the technical problems that the seeds and the soil cannot be fully contacted when supplementing the alpine grassland, the grassland lacks water, the temperature difference is large, the nutrient is low, and the seeds are not easy to germinate. The planting grain and its preparation method solve the problems of seeds drifting with the wind, poor landing stability, low sowing accuracy and germination rate, low uniformity, and weak root system when grass seeds are sown on degraded alpine grasslands.
