How to solve the 10.73 billion mu "Wang Tiantian"?

[ China Agricultural Machinery Industry News ] China's total water resources account for 6% of the world's total, and the per capita water resources are only 1/4 of the world's. Under the rigid constraints of water shortages, the annual agricultural irrigation water consumption is 360 billion cubic meters, which is used to produce 26% of the world's agricultural products and to support 20% of the population. In China's existing 2.25 billion mu of cultivated land, not only the utilization rate of irrigation water is only 52%, but also 1.073 billion mu is the “Wangtiantian” without irrigation conditions. How to alleviate the contradiction between water supply and demand and promote the sustainable use of water resources.

How to solve the 10.73 billion mu "Wang Tiantian"?

On December 17, at the Third National Symposium on Water-saving Irrigation Equipment and Technology Strategy held in Xuzhou, Jiangsu Province, experts pointed out that although agriculture is a major water user, it must be ensured that agriculture is not only the survival of the people but also the economic development. It is an important part of the ecological environment. The key to alleviating the contradiction between water supply and demand is to vigorously develop irrigation and drainage equipment and improve water utilization efficiency, and realize scientific, simple, automatic and utilization of water resources.

Gao Xiangzhao, an expert from the National Agricultural Technology Center of the Ministry of Agriculture, believes that in agricultural production, extensive water flooding is a waste of water, low efficiency, large amount of irrigation and drainage of ditches, and low water resource utilization. Therefore, the development of irrigation and drainage machinery and the implementation of water-saving irrigation are sustainable in agriculture. The inevitable choice for development. The implementation of water-saving irrigation should be transformed from channel water delivery to pipeline water transportation, from irrigated land to water supply to crops, from water and fertilizer to water-fertilizer coupling, from single technology to integrated management, to achieve scientific use of water resources.

Yuan Shouqi, secretary of the Party Committee and president of Jiangsu University, believes that the development and energy-saving technologies and products have become an inevitable trend in the development of irrigation and drainage machinery technology. They are the main direction of product design and manufacturing. Intelligentization and informationization are the comprehensive improvement of development quality in the irrigation and drainage machinery industry. And the key link of core competitiveness, the integration of the Internet platform and information and communication technology into the product life cycle, to achieve digital, network and intelligent production process, the formation of "Internet + irrigation and drainage machinery standard parts" is a future development model. The “Thirteenth Five-Year Plan” should promote the drainage and irrigation machinery industry to a high quality direction with the standardization as the engine, the application of new materials, new technologies, new technologies and the integration, completeness, systemization, generalization and diversification of technical equipment. development of.

The seminar was hosted by the China Agricultural Machinery Society Drainage and Irrigation Machinery Branch, China Machinery Industry Standardization Technical Association Drainage and Waterlogging Professional Committee, Jiangsu University Fluid Machinery Engineering Technology Research Center, National Pump and System Engineering Technology Research Center and Jiangsu Huayuan Water Saving Co., Ltd.
