High efficiency planting method for improving common saline land and serious saline land of dig-built type platform field

Abstract

The invention discloses a highly effective planting comprising the steps of, shoveling with a ditching machine and raising the field, controlling the elevated ground surface height to 1.6-2.0m, stabilizing the groundwater under the trench water level, pumping alkali with fresh water in spring, and conducting salt washing and desalination with river water. The method can reduce the salt content from 0.4-1.0% to below 0.2%.

Description

1. Technical field: [0001] The invention belongs to the agricultural planting technology, and is mainly applicable to a high-efficiency planting method for improving medium and heavy saline-alkali soils by excavating terraced fields in coastal areas. 2. Background technology: [0002] In the coastal area, the improvement of medium and heavy saline-alkali land has always been a major research topic for the majority of scientific and technological workers. Some improvement methods and measures in the past have not achieved a complete cure effect. However, there is no record that the salt content of the plow layer of the soil before improvement is reduced from 0.4-1.0% to below 0.2%. 3. Contents of the invention: [0003] According to the above conditions of heavy saline and alkaline land in the coastal area, the present invention provides a digging-type terrace to improve medium and heavy saline land and a high-efficiency planting method to solve the problem of radically cur...
