Sand soil fertility promotion circulation system

Abstract

The invention discloses a circulation system for sand soil fertility improvement, including a water storage unit, a return flow unit, a seepage diversion layer, a sand protection layer and several independent water supply and drainage matrices, and the water storage unit, return flow unit and supply and drainage matrix form a sustainable water cycle , where the water supply and drainage matrix can operate jointly or selectively independently. The water supply and drainage matrix of the present invention is independent, and forms a network independently with each other, which can realize joint use or arbitrarily selected use, and the application of the circulation system is more flexible; the height difference laying of the water supply and drainage matrix can be carried out according to the requirements of different thicknesses of sandy soil layers , flexible selectivity, to meet the needs of various landforms and terrains; the seepage diversion layer is used to divert the water in the sand and play the role of water accumulation and confluence, which improves the water cycle utilization rate of the circulation system and improves the efficiency of the circulation system. Sustainability; the structure of the water supply and drainage matrix and fertilization matrix is ​​easy to assemble and lay, and the construction is convenient and fast.

Description

Technical field [0001] The present invention relates to the technical field of sand and soil and geostative improvement, and in particular, there is, in particular, there is an inkodilizing cycle system. Background technique [0002] The sand finger is mixed by a large amount of sand and a small amount of clay, and it refers to the soil that is large. [0003] The formation of sand has both natural factors, and some people are factors. Surface loose sand sediments are the soil of sandy soil. Its native process is an anti-wet climate environment, the wind erosion, sand buried, the leaching process and the aliasing of the biological sand, the aggregate nutrient process. Its formation is that the soil is weak, often interrupted for wind erosion and sand pressure, and it is difficult to form a complete soil profile. Keep the mother body. The organic matter content of the sand is small, the soil is thin, the water is insufficient, leak, and drain. [0004] In the prior art, it is gene...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art, such as the traditional sandy soil with little effect of improving soil fertility and poor sustainability, and the traditional circulation system with complex laying, low water seepage recovery rate, poor sustainability, and easy blockage, etc.
