| Humic acid is an important component of soil organic matter in farmland, and it is the most dynamic core material of soil life. To study the problems of soil structure degradation, low efficiency of water\|fertilizer, low yield and efficiency in the development of dryland farming, this paper summarized the biochemical humic acid and coal\|based humic acid resources and its industry development progress and analyzed the principle of the composition characteristics of humic acid in improving soil structure, maintaining soil acid and base balance, and improving fertilizer utilization efficiency and stimulating crop growth and crop quality and reducing heavy metal pollution. It also examined the application of humic acid in acid soil, saline\|alkali soil improvement and soil structure improvement on water and fertilizer maintenance in abandoned land and introduced the development materials and the effects of water conservation fertilizer with humic acid, soil amendment with humic acid and the heavy metal pollution treatment. The development trend and demand of dryland agriculture and the application of humic acid in arid areas and future direction of the research and development of humic acid in dryland farming were also discussed. |
