Breve descrição da melhor prática

High Vertical Living Sand Barrier is a protective barrier set in the wind and sand stricken areas. The barrier with certain height and penetrability is made up of growing plants suitable for dry and sandy conditions to alleviate the wind and sand drifting speed through the rows of plants, and finally piling up the drifting sand. It is an effective sand fixation approach to protect infrastructure from being ravaged.

Breve descrição das principais atividades, por objetivo

1. Select cutting of C. klementzil and one year seedlings of Haloxylon ammodendron for planting, with plant space 10 cm of more.
2. Check the plant survival condition in the spring following the establishment of the plant barrier, conduct replanting to the unplanted of dead. 3. The living sand barrier built should be looked after by specialized people to avoid damages of domestic animals.|
1. 2-4 belts of windbreak are proper for the seriously affected areas and 1-2 belts are suitable for lightly affected places.
2. The first belt of windbreak should be planted perpendicular to the wind direction about 200m to the rail tracks to be protected at the windward side.
3. Further, windbreaks should be planted in 20m intervals to total 2-4 belts in parallel with the first one.

1. High vertical living sand barrier is built in spring.
2. On drift sand site, draw straight line perpendicular wind direction of afforestation, at the span of about 20m.
3. Afforestation and watering.|

Breve descrição e especificações técnicas da tecnologia

Select suitable plant species and determine row spacing and specifications according to drift sand condition, especially drift intensity, and to form a high vertical barrier.
The first belt of windbreak should be planted perpendicular to the wind direction about 200m to the rail tracks to be protected at the windward side. Further, windbreaks should be planted in 20m intervals to total 2-4 belts in parallel with the first one. Calligonum klementzil, Haloxylon ammodendron, Salix psammophila, etc. may be planted. 25cm or longer cuttings, or one year old seedlings in 30cm are proper for the plantation of Calligonum and Salix psammophila; one year old seedlings of 30cm in length suits planting of Haloxylon ammodendron. Initial density should be kept in 10-12 tree/m.
