Problems solved by technology

However, this method also has obvious defects: it is easy to cause secondary compaction of the soil, and the saline-alkali backlash is serious
Biological improvement requires the smallest investment, but the requirements for salt-tolerant plants are relatively high. It is necessary to have a better understanding of the salt-tolerant mechanism of halophytes, and biological improvement is often slow to take effect
[0017] Therefore, the effect of adopting the traditional single governance method is not ideal, and due to the serious mutual constraints among the various methods, simply integrating the tradition

Abstract

The invention discloses a saline-alkali soil improving method by engineering-chemistry-biology-desalination and water conservation-information technology. The saline-alkali soil improving method includes steps of S1, lowering salt content in the saline-alkali soil to be treated gradually by engineering measures and isolating and discharging soluble salt in the soil; S2, reasonably utilizing water resource of the saline-alkali soil to be treated by brackish water desalination technology; S3, reasonably irrigating the saline-alkali soil to be treated by water-saving irrigation technology; S4, online detecting the saline-alkali soil to be treated by information technology; S5, improving chemical components of the saline-alkali soil to be treated by chemical measures; S6, finally improving the saline-alkali soil to be treated by biotechnology measures. The saline-alkali soil improving method provides a feasible, economic and efficient scheme for improving the saline-alkali soil in coastal regions, improvement time is short, effect is good and no backflow is caused after improvement.

Description

technical field [0001] The invention relates to a method for improving saline-alkali land, in particular to a comprehensive method for improving saline-alkali land by integrating engineering technology, biological technology, chemical technology, brackish water desalination technology, water-saving irrigation technology and information technology. Background technique [0002] With the deterioration of the ecological environment, soil salinization is expanding at an unprecedented speed. Therefore, rational use of saline-alkali land, thorough improvement of saline-alkali land, and cultivation of saline-alkali-resistant plant varieties will be the future development direction. [0003] As far as my country is concerned, the total population has reached 1.3 billion, and the total cultivated land area is less than 2 billion mu, but the total area of ​​saline-alkali land has reached 2.045 billion mu, and its area is constantly expanding; the per capita cultivated land and fresh w...
