In the north, Sedum sarmentosum is better than Sedum sarmentosum in roof greening, because Sedum sarmentosum is more cold-resistant and high-temperature-resistant, with longer green period and better landscape effect.
"Sedum sarmentosum has stronger cold resistance, heat resistance and drought resistance than Sedum sarmentosum" (Tan China New Lawn Ground Cover). Sedum sarmentosum is a kind of lawn grass without watering, which has strong drought resistance.
Sedum sarmentosum has the following advantages:
1, drought resistance and high temperature resistance: Sedum sarmentosum can adjust its moisture when it is dry; Strong water absorption capacity, and it will not dry up without watering for a month (including natural precipitation); Sedum sarmentosum is extremely resistant to high temperature: it can still grow vigorously at a high temperature of about +45℃.
2. Strong cold resistance: when the lowest temperature in Shenyang reaches -32℃, it can safely overwinter without freezing injury.
3. Humidity resistance, saline-alkali resistance and barren resistance: it can grow in the crevices of rocks on the hillside all the year round.
4. The green period is long and the ornamental value is high: the ornamental period of Shenyang green leaves is as long as 8-9 months, generally turning green at the end of March and withering in 65438+early February. Beautiful grass, green as jade, quite neat and spectacular; Golden and bright color, high ornamental value.
5. Strong ability to resist pests and diseases: it has been used in Shenyang for many years and basically has no pests and diseases.
6, fast growth, easy reproduction, no need to prune.
As long as Sedum sarmentosum lawn is laid in the project, it generally does not need maintenance management such as watering and pesticide application, and it can maintain good green and coverage through natural precipitation, providing excellent landscape effect. Compared with similar products, it can greatly reduce the maintenance cost of lawn.
In Shenyang, Sedum sarmentosum has been used in many urban landscape projects, such as roof greening, ground cover plants, slope protection, flower beds, hanging baskets and so on. And the effect is excellent. Among them, the ground cover and slope protection project along Qingnian Street in Hunnan Development Zone, Shenyang was well received by the Management Committee of Hunnan Development Zone and peers.
Sedum sarmentosum, as a lawn grass, is worthy of wide application in urban landscape engineering such as roof greening, ground cover, slope protection, flower beds and hanging baskets.
