These approaches help to reduce soil salinity, enhance soil fertility, and improve soil structure, thereby supporting healthy plant growth. The authors found that targeted improvement techniques are necessary for different regions.
For instance, in the arid northwest part of China, mulched drip irrigation can significantly reduce water evaporation, control the rise of salts, and improve irrigation water use efficiency. In the Northeast, rice planting can improve the physical structure of alkaline soils and lower soil pH. In the North China Plain, appropriate utilization of saline water for agricultural irrigation is favorable to salt leaching and can also partially replace freshwater resources.
Additionally, constructing fertile soil layers is crucial via employing various measures to improve soil quality and establish fertile arable layers.
In recent years, the concept of "crop for saline soil" in terms of improving plant tolerance to saline-alkali soil has been proposed, and the authors review the relevant progress and development advances including halophyte planting, saline-alkali tolerant crop breeding and functional microbial agent research.
These plant-oriented approaches can not only significantly improve the utilization efficiency of saline-alkali land, but also improve the yield and quality of crops.
