Selection of vegetation for slope greening

  The selection of plants suitable for local growth is a key link.In the selection of greening materials, the first consideration is the temperature.The highest temperature determines whether the plant can survive the summer safely, and the lowest temperature determines whether the plant winters safely.Therefore, in the south, warm season plants, Bahia grass, dogtooth, and thrift are all suitable species of grass.In the north, cold season plants, such as tall fescue, perennial ryegrass, white clover, etc.In addition, local wild plant resources are often the best choice, it is the result of long-term evolution in the local climate and soil environment, the most suitable for the local environment.There are abundant plant resources in China, but there are few works in this field, such as thatched grass, wild pea, Amorpha fruticosa and so on.
