Horsetail Beefwood Windbreak along seaside (Huang Xinquan)

Horsetail Beefwood (Casuarina) Windbreak along Seaside (China)

Seaside Shelter Belt of Horsetail Beefwood' test

Description

Planting Horsetail Beefwood as a shelter belt along seaside to prevent serious wind and water erosion/destroy of the cropland.

Horsetail Beefwood windbreak along seaside is applied to prevent serious wind and water erosion/destroy of the cropland. It is planted as a shelter belt in the cropland. Horsetail Beefwood is a perennial tree growing in sub-tropic and tropic climate. Its timber can be used in industry and fuel timber. It is easy to maintain.
