Title:
SOIL CONDITION IMPROVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/096669
Kind Code:
A1
Abstract:
A soil condition improving device comprises a hollow annular body (1). A plurality of raised-ridge elements (2) is disposed on the periphery of the hollow annular body (1). Each raised-ridge element (2) outward extends to form multiple raised peaks (3) disposed at intervals, and the raised peak (3) can extend into a pit (8) when the pit is formed by using the raised-ridge element (2) on a soil surface, so as to further form a concave hole (6), and the concave hole (6) can enable the soil surface not to be compacted, further facilitating keeping of water permeability of the soil. When the soil condition improving device rolls on the soil surface, the raised-ridge elements (2) form a series of reinforced hull-shaped pits (8) on the soil surface, and the raised peaks are further pressed at the bottom of the pits to form a series of small tapered concave holes (6), so as to prevent surfaces of the outer edges of the raised-ridge elements (2) from compacting the soil. By using the device, the soil can be reinforced but are not compacted, a soil surface area can be increased, a soil temperature can be improved, soil permeability can be enhanced, water utilization can be improved, the crop growth can be promoted, and the production gain can be improved on the basis of effectively preventing water and soil loss.
