Tridge summary
Editor’s note In recent years, the Ministry of Agriculture and Rural Affairs has actively promoted saline-alkali land aquaculture in conjunction with relevant scientific research units and fisheries authorities at all levels. This technology has become more mature and its development models have been diversified. It has not only effectively turned waste into treasure and improved the comprehensive production capacity of saline-alkali water fish and farmers, but also And realize the utilization of saline-alkali water and soil resources. This report focuses on a new model for the healthy development of saline-alkali land aquaculture, so stay tuned. In mid-winter, in the rows of fish ponds on a large saline-alkali land in Wufo Township, Jingtai County, Gansu Province, splashes of aerators rolled out Adding vitality to the fish, a ridge of small tomatoes and strawberries in the big shed by the pond grows gratifyingly. This model of "digging ponds to reduce salt and fish to control alkali" has changed the past saline-alkali land "watery in summer and white in winter" The successful practice of saline-alkali land aquaculture in Jingtai County is the fruit of the comprehensive utilization of saline-alkali land water resources promoted by the Ministry of Agriculture and Rural Affairs in recent years. The promotion of this technology not only "turns waste into treasure", realizes saline-alkali water and soil resources Improve the comprehensive production capacity of saline-alkali water for fisheries and farmers; and "use fish to control alkali" to improve the soil structure, realize the re-cultivation of saline-alkali land, improve the ecological environment, and take a road of comprehensive management of saline-alkali land for sustainable development. Policy guidance actively promotes saline-alkali fishery Healthy development China has 1.48 billion mu of saline-alkali land resources, and there are also about 690 million mu of low-lying saline-alkali waters. For a long time, the outlet for washing salt and discharging alkali water has become a bottleneck problem in the management of saline-alkali land. Saline-alkali fishery refers to digging ponds on saline-alkali land. Raise fields, integrate various technologies such as improving and regulating the quality of saline-alkali water, and carry out fishery aquaculture production.

In mid-winter, in rows of fish ponds on a large saline-alkali soil in Wufo Township, Jingtai County, Gansu Province, the water splashed by the aerator adds vitality to the fish. A row of small tomatoes and strawberries grows gratifyingly in the greenhouse by the pond. The model of "digging ponds to reduce salt, and using fish to control alkali" has ...
