What methods can be taken to protect water resources and save water in agricultural production?

Agricultural water resources include surface water, groundwater, soil water and purified wastewater.

Under the condition of sustainable development, the methods to ensure the safety of water resources include strengthening water-saving management, rational development and utilization of water resources, increasing sewage treatment and improving water environment.

First, strengthen water-saving management.

1, vigorously promote water-saving technology, water-saving equipment and water-saving appliances. New construction, renovation and expansion of industrial projects, the competent department of the project in the examination and approval of construction and water administrative departments for examination and approval of water permits, with the production process in line with the requirements of the province's water quota as the standard.

2. Adjust the agricultural structure and build water-saving and efficient agriculture. Popularize drought-resistant and high-quality crop varieties, and popularize high-efficiency water-saving agricultural supporting technologies that combine engineering measures, management measures, agronomic measures and biological measures.

Second, rational development and utilization of water resources.

1, strictly limit the exploitation and use of self-prepared wells. In the future, unless it is really necessary to take water to solve the problem of drinking water in rural areas, new self-prepared wells will no longer be approved, and all self-prepared wells within the coverage of urban water supply network will be shut down before the end of the year.

2. Optimize the allocation of water resources. Encourage the use of non-traditional water resources such as reclaimed water, brackish water and rainwater in flood season; Give priority to the use of shallow groundwater, control the exploitation of deep groundwater, and comprehensively use administrative and economic means to realize the optimal allocation of water resources.

Third, strengthen sewage treatment and improve the water environment.

1. Where a sewage outlet into the river is set, an application for setting the sewage outlet into the river shall be submitted to the water administrative department before the environmental impact report of the construction project is submitted to the administrative department of environmental protection, and the water administrative department shall make a reasonable setting after examination and approval.

2, accelerate the construction of urban drainage pipe network, in accordance with the principle of "drainage pipe network first, then sewage treatment facilities", accelerate the construction of urban drainage pipe network.
