Develop high-efficiency water-saving irrigation action to develop sprinkler irrigation technology
[ China Agricultural Machinery Industry News ] In China, agriculture is a major water user, agricultural water consumption accounts for about 63.1% of the total economic and social water use, and in some areas up to 90%, but the problem of low water use efficiency and low automation is widespread. Therefore, vigorously developing agricultural water-saving and promoting water-saving irrigation technology is conducive to expanding irrigation area and improving irrigation water efficiency while agricultural water consumption is basically stable. It is also promoting sustainable use of water resources, ensuring national food security, and accelerating economic development. Important measures of the way.
Carry out water-saving irrigation action and vigorously develop sprinkler irrigation technology
Since 2011, the state has attached great importance to the development of water-saving irrigation, and has successively issued the “Decision on Accelerating Water Conservancy Reform and Developmentâ€, “National Water-saving Irrigation Development Twelfth Five-Year Planâ€, “Water Conservancy Development Plan (2011-2015)â€, National Agricultural Water Conservation Program (2012-2020), "Opinions on Promoting Comprehensive Reform of Agricultural Water Price", "Interim Measures for the Management of Water Rights Transaction", "Implementation Plan for Promoting Water and Fertilizer Integration (2016-2020)", "Farmland The Water Resources Regulations and other policy documents have accelerated the development of agricultural water use.
In the “Thirteenth Five-Year Plan†of the Five-Year Plan, it is clearly proposed to carry out large-scale water-saving irrigation operations in key irrigation districts, during which the newly-built water-saving irrigation project covers an area of ​​100 million mu. With the focus on water saving in the northeast, water saving in the northwest, water saving in North China, and water saving in the south, the construction of water-saving irrigation projects will be promoted in a regional and large-scale manner.
On the 6th of February, Tang Renjian, deputy head of the Central Rural Work Leading Group and director of the office, said that the groundwater over-exploitation is very serious and the spatial and temporal distribution of water resources is very uneven. Especially in the three north areas of North China, Northwest China and Northeast China, it is the main production area for grain production. In the long run, China solves the problem of water shortage and high water consumption. The effective way is to save water. Therefore, we must focus on agricultural water conservation as a directional and strategic event. It is necessary to vigorously implement regional large-scale water-saving irrigation operations, concentrate on the construction of a number of water-saving irrigation projects, and steadily promote the construction of water-saving irrigation forage materials in pastoral areas, and strictly limit the extraction of groundwater irrigation artificial grassland in ecologically fragile areas. Accelerate the development of water-saving irrigation technologies and products with complete range, series matching and reliable performance.
As a way of water-saving irrigation, sprinkler irrigation has been continuously improved and improved for more than 100 years, and has developed into an advanced irrigation technology with economical efficiency and mature technology. According to statistics from the Ministry of Water Resources and other relevant departments, the area of ​​sprinkler irrigation projects in the country has reached 457 million mu, accounting for nearly 20% of the national water-saving irrigation project area. In particular, the area of ​​the sprinkler irrigation project in the northeastern region (including the central and eastern Inner Mongolia) is relatively rapid, accounting for 63% of the national sprinkler irrigation project area. In recent years, with the vigorous promotion of the national land transfer policy, many large-scale growers will bring breakthrough growth to the market development of the sprinkler irrigation industry.
It is understood that in order to improve the scientific and technological level of sprinkler irrigation products and equipment and promote the healthy and sustainable development of the sprinkler irrigation industry, China Agricultural University held the “First National Sprinkler Irrigation Technology and Industry Development Forum†in Beijing on March 27-28. Representatives from upstream and downstream of the sprinkler irrigation industry chain, such as government departments, research institutes, production enterprises and end users, will be invited to analyze the policy environment, market trends and technical problems faced by the sprinkler irrigation industry development, directly attack industry issues and dig deep into the industry. Contradictions, sharing innovative technologies, exchanging corporate experience, and exploring industrial development models in the new economic environment.
Liu Yang, founder of Beijing Irrigation Network Technology Co., Ltd., said that in recent years, the degree of attention paid by sprinkler irrigation in water-saving agriculture has been generally lower than that of micro-irrigation, but in fact, sprinkler irrigation equipment has a single acre in the development of large-scale agriculture. Low cost, easy management, high degree of automation and many other advantages. It is hoped that the society will pay more attention to it, especially the development of sprinkler irrigation technology in the main grain producing areas such as North China, Northwest China and Northeast China, which is more conducive to promoting the development of agricultural scale.
