61 results about "Sandhill" patented technology

A sandhill is a type of ecological community or xeric wildfire-maintained ecosystem. It is not the same as a sand dune. It features very short fire return intervals, one to five years. Without fire, sandhills undergo ecological succession and become more oak dominated.

Wind prevention and sand fixation greening planting technology

The invention discloses a wind prevention and sand fixation greening planting technology with good sand control effect. The wind prevention and sand fixation greening planting technology mainly comprises the following steps of: firstly arranging a plurality of strip sand-protecting barriers in a traveling dune zone; then mix-seeding herbaceous plant seeds in open grounds among the strip sand-protecting barriers, and planting shrub seedlings at the positions where the strip sand-protecting barriers are located; and finally fertilizing among the strip sand-protecting barriers and inside the strip sand-protecting barriers. According to the wind prevention and sand fixation greening planting technology, normal germination growth of most herbaceous plant seeds and shrub seedlings can be ensured without planting by multiple times; moreover, the growth period of herbaceous plants is relatively short, so that grass capable of sand fixation can be formed in a short time to further ensure normal growth of shrub seedlings; a grass and shrub forest can be formed in a relatively short time, two to three years in general, through the combination of the sand fixation of sand-protecting barriers with grass and shrub plants so as to achieve the effects of wind prevention and sand fixation; and the desertification of land can be effectively prevented.
