Coastal heavy solonchak 5N rapid high efficiency desalting method

Abstract

The invention discloses a coastal heavy solonchak 5N rapid high efficiency desalting method, and belongs to the technical field of mudflat solonchak improvement. The method includes: tillage, soil sunning, soaking, water rotation, and salt discharging, and the five steps are cycled for many times, multiple water rotation tillage is a key of the technical system, and is an important key to achievement of rapid desalting. The advantages of the invention are that watering and drainage are easy to perform in a field, the operation flow is complete and is easy to implement, the electricity safety is high, the desalting efficiency is high, rapid high efficiency desalting of coastal heavy salt fields is facilitated, and a cultivation level of the coastal heavy salt field can be reached; and the coastal heavy solonchak 5N rapid high efficiency desalting method has economic value and social meaning to coastal mudflat soil resource development and utilization, grain production, environment protection, and salt-tolerant plant research.

Description

technical field [0001] The invention relates to saline soil desalination technology, in particular to a fast and efficient desalination and desalination method for coastal heavy saline soil, and belongs to the technical field of coastal beach land improvement. Background technique [0002] China's coastal wetlands are vast and rich in land resources. However, some original sea salt production sites have left large areas of coastal land idle and wasted due to reasons such as closure, suspension of production, and business transfer. These salt fields are characterized by extremely high salinity, heavy compaction, and exceptional fertility Low, even salt-tolerant plants are difficult to grow; how to improve these lands, so that the heavy salt fields that could not grow food plants before become good fields with a yield of 1,000 jin of rice is the purpose of this case. , food production, environmental protection and salt-tolerant plant research all have economic value and social...

[0002] China's coastal wetlands are vast and rich in land resources. However, some original sea salt production sites have left large areas of coastal land idle and wasted due to reasons such as closure, suspension of production, and business transfer. These salt fields are characterized by extremely high salinity, heavy compaction, and exceptional fertility Low, even salt-tolerant plants are difficult to grow; how to improve these lands, so that the heavy salt fields that could not grow food plants before become good fields with a yield of 1,000 jin of rice is the purpose of this case. , food production, environmental protection and salt-tolerant plant research all have economic value and social significance; there are many existing methods of desalination and desalination of salt fields through irrigation and drainage. The mechanical irrigation and drainage method with water pumps; manual digging and filling irrigation and drainage methods are labor-intensive, difficult to operate, low in efficiency, poor in irrigation and drainage effects, and easily cause soil loss. The mechanical irrigation and drainage method of water pumps has complex facilities and consumes more power and The investment cost is high, cable laying and installation of electrical cabinets are difficult, easy to get an electric shock and poor in safety; the most important thing is that the existing saline soil desalination method is very simple and the process is not detailed. Other methods, so the desalination effect is not good
