Abstract
The invention provides a double-layer composite underground drainage device for improving farmland soil of coastal mud flat reclamation areas by combining short-term rapid drainage desalination with long-term control accumulation of salt. The device comprises a short-term shallow straw gap underground drainage system salt leaching channel, a stream collecting and fixing water absorption subdrain and an open drain on the coastal mud flat saline-alkali soils, wherein the salt leaching channel is positioned above the stream collecting and fixing water absorption subdrain and is arranged with the stream collecting and fixing water absorption subdrain in parallel; the open drain is arranged at the water outlet end of the subdrain and the salt leaching channel; the water head difference is formed between the open drain and the coastal mud flat ground surface. The drainage method method comprises the steps of leaching the salt in the coastal mud flat soil by using the percolation generated by irrigation or rainfall, enabling the salt to enter into the shallow straw underground drainage system salt leaching channel and the stream collecting and fixing water absorption subdrain along the stream, discharging the salt in the soil along the water, and leading to the open drain. After the underground drainage system salt leaching channel formed by shallow straw gaps is deformed caused by pressure, the channel can still keep excellent drainage and salt elimination performance, so that the technical problems that the plastic corrugated subdrain is easy to deform and not suitable for shallow burying after being subjected with burying and operation agricultural implements dynamic load pressure can be solved.
Description
Technical field
The present invention relates to bilayer combination underground drainage device and the water discharge method thereof of the improvement Coastal beach reclamation area agricultural land soil that the desalination of a kind of short-term Quick drainage combines with the long-term control accumulation of salt in the surface soil.
Background technology
Very long and the plain coast large percentage in China coastline, and containing more salt and alkali component in the Coastal beach soil body, the suppression that its bad physico chemical property cause the growth of most plants to be subject in various degree, even can not survive.The large-area Coastal beach salt affected soil of modified utilization effectively and rationally, can alleviate that arable land is day by day reduced, freshwater resources are not enough and population constantly increase between contradiction.
So far, China administers and utilizes saline soil substantially to have two kinds of approach: one is comprise the abiotic technical measures such as cultivation and fertilization, soverlay technique, water resources industry, chemical measure, electromagnetism improvement.The method changes water and soil character and ecotope by dropping in a large number, to adapt to plant growth, but the deficiency of Coastal beach ground freshwater resources, the scale that the reclamation of salinep-alkali soil is utilized and effect are difficult to there is large breakthrough for a long time.Two is the modified utilization approach containing the biotechnologys such as Screening of Germplasm, distant hybridization cultivation, gene engineering cultivation.The method adopts excavation, introduces, screens, cultivates a kind of development mode that the salt-tolerant plant with certain economic value carries out alkaline land improving.
At present, the utilization of China in saline land with administer to improve etc. in defined some single technologies, possessed certain technological reserve.But because various places exist difference in saline and alkaline the barrer types, physioclimate resource, economic society feature etc.; be difficult to agriculture and forestry efficiency utilization supporting technology and the application model thereof of unified use standard when zones of different, dissimilar alkaline land improving, thus many technical measures also have with a certain distance from scale application.Therefore, seeking suitable technical measures, is the core determining reclamation result, is also the key factor of early development benefit height.
Saline land is typically employed in underground and arranges the mode that fixed current collect hidden pipe and realize salt discharge, hidden pipe material adopts plastic film capicitor usually, but plastic ripple hidden pipe exist be subject to burying mutability after soil and operation farm machinery dynamic load pressure, should not the technical barrier of shallow embedding, way is in the past lay open drain shallow and close in a large number in field to accelerate Soil Desalting mostly, and the method soil pressure is useless many, easily silt is shallow, quantities large, invest high, weak effect.
Summary of the invention
