Sandy soil fertility promoting circulating system

Abstract

The invention discloses a sandy soil fertility promoting circulating system which comprises a water storage unit, a backflow unit, a flow seepage and guide layer, a sandy soil protection layer and a plurality of independent water supply and drainage matrixes. Sustainable water circulation is formed by the water storage unit, the backflow unit and the water supply and drainage matrixes, and the water supply and drainage matrixes can be combined to operate or selectively and independently operate. According to the sandy soil fertility promoting and circulating system, the water supply and drainage matrixes have independence and autonomously form a net, combined use or randomly alternative use can be achieved, and the circulating system is more flexible in application. Height differentiatinglaying of the water supply and drainage matrixes can be carried out according to the need for different depths of a sandy soil layer, the selectivity is flexible, and the on-site laying needs of various landforms and terrains are met. The flow seepage and guide layer is adopted for guiding water in sandy soil, a water gathering and flow converging function is achieved, the water circulation use rate of the circulating system is increased, and the sustainability of the circulating system is improved. The structure for the water drainage matrixes and fertilizer applying matrixes is easy to assemble and lay, and construction is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of sandy soil water and soil conservation and soil fertility improvement, in particular to a sandy soil fertility improvement circulation system. Background technique [0002] Sandy soil refers to soil mixed with a large amount of sand and a small amount of clay, and generally refers to soil with a large sand content. [0003] The formation of sandy soil has both natural factors and man-made factors, and man-made factors are the main ones. The loose sandy sediment on the surface is the parent material of sandy soil. The soil-forming process takes place under the combined action of wind erosion, sand burial, leaching process, biological sand fixation, and accumulation of nutrient elements in a semi-humid climate environment. Its formation is characterized by weak soil formation, often interrupted by wind erosion and sand pressure, and it is difficult to form a complete soil profile. Keep the parent materia...
