China’s water resources are in serious shortage, and the contradiction of agricultural water use is becoming increasingly prominent. To develop modern agriculture, change the mode of agricultural development, promote disaster prevention and reduction, and achieve stable and increased agricultural production, we must vigorously develop water-saving agriculture. In order to implement this year’s central governmentoneDocumentNo. and the spirit of the instructions of the CPC Central Committee and the leading comrades of the State Council on vigorously developing water-saving agriculture, and accelerating the sound and rapid development of water-saving agriculture, this opinion is formulated.
First, fully understand the great significance of developing water-saving agriculture
Agriculture stands on soil, prospers with fertilizer and prospers with water. Water is one of the most scarce agricultural resources, and it is also a key factor restricting the sustainable development of agriculture. Agricultural departments at all levels should fully understand the significance of water-saving agriculture in ensuring national food security and changing the mode of agricultural development, earnestly enhance their sense of responsibility and urgency, seize the opportunity, and accelerate the development of water-saving agriculture.
(A) The contradiction of agricultural water shortage is becoming more and more prominent.China’s total water resources only account for the world’s.6%Per capita is less than a quarter of the world average. Agricultural water consumption is about3600Billion cubic meters, the proportion of water from1997Annual69.7%Drop to the current61.3%About, reduced200Billion cubic meters. With the population growth, especially the acceleration of industrialization and urbanization, the contradiction of water use between workers and peasants and between urban and rural areas has further increased, and the difficulty of ensuring agricultural irrigation water has been increasing. At present, the irrigation area of farmland in China9.05100 million mu, irrigation water gap300More than 100 million cubic meters. According to the national water resources development plan, the future15The annual agricultural water consumption will maintain zero growth, and the situation of agricultural water shortage is becoming increasingly severe.
(2) The threat of drought to agricultural production is increasing.With the global warming, the frequency, scope and severity of drought in China are getting higher and higher, and the threat of drought and water shortage to agricultural production is getting bigger and bigger. Drought has become the normal state that affects the development of grain and agricultural production, and the sustainable development of agriculture is facing a serious threat. near10In recent years, the average annual drought area in China has beenfourAbout 100 million mu, which is the last century.50S more than twice, the average annual disaster area.2More than 100 million mu, grain loss due to drought.600More than 100 million Jin. Therefore, we must take the development of water-saving agriculture as a revolutionary measure and explore a way to use water reasonably and efficiently.
(3) The potential of developing water-saving agriculture is increasingly apparent.At present, all over the country9.05Of the 100 million mu of irrigation area, the water-saving area of engineering facilities only accounts for.44.3%; exist23Agronomic water-saving area accounts for only 100 million mu of crop planting area.17.4%. The utilization rate of agricultural water in China is lower than that in developed countries.twentyAccording to the calculation of relevant experts, by popularizing water-saving technology in farmland, it can save water in wheat and rice production in irrigation areas.360The potential of 100 million cubic meters is equivalent to the new irrigation area.8200Ten thousand mu, increase production per mu.300Jin grain calculation can increase grain production capacity.246Billions of Jin. Improving the utilization rate of natural precipitation in dry farming areas has the following advantages.260100 million cubic meters of potential. At the same time, the grain production efficiency of irrigation water will be improved by popularizing farmland water-saving technology.0.1kilogram/Cubic meters, the grain production efficiency of precipitation per millimeter in dry areas is improved.0.1kilogram/Mu, can increase grain production capacity.1000More than 100 million Jin is equivalent to the national goal of increasing grain output by 100 billion Jin.
(D) The policy of developing water-saving agriculture is getting stronger and stronger.The CPC Central Committee attaches great importance to the work of water-saving agriculture, and has issued a series of supporting policies in recent years to promote the development of water-saving agriculture. In the face of the drought in southwest China the year before last, arrangements were madethree100 million yuan was used for the popularization of plastic film mulching technology, and it was arranged last year.five100 million yuan for plastic film mulching in northwest China. All localities responded positively, integrated resources, increased investment, and made overall planning and coordination to form a joint force. According to incomplete statistics, the whole society invests as much money in water-saving agriculture every year.50More than 100 million yuan. The development situation of water-saving agriculture is getting better and better, the atmosphere is getting stronger and stronger, the policies are getting stronger and stronger, and the agricultural water-saving technology modes such as full film mulching and drip irrigation under film are becoming more and more mature, which has created rare opportunities and conditions for planning large projects, building large demonstration areas and popularizing and applying new water-saving agricultural technologies in a large area.
Two, accurately grasp the guiding ideology and objectives and tasks of developing water-saving agriculture.
Agricultural departments at all levels should further clarify the working ideas of developing water-saving agriculture, clarify the objectives and tasks, highlight regional characteristics, and accelerate development.
(5) Guiding ideology.Adhere to the guidance of Scientific Outlook on Development, according to the requirements of building a resource-saving and environment-friendly society and accelerating the transformation of agricultural development mode, firmly establish the concept of "saving water and increasing production, saving water and increasing efficiency", comprehensively apply engineering, agronomy, biology, management and other measures according to the law of crop water demand and the characteristics of agricultural water resources utilization, accelerate technology integration, and demonstrate and popularize water-saving agricultural technology on a larger scale and at a higher level with the construction of demonstration areas as a platform; Establish an investment mechanism led by the government and widely participated by all sectors of society, and greatly increase the investment in farmland water saving; Further strengthen the construction of functions and means, establish and improve the national soil moisture monitoring network system, and establish and improve the grass-roots water-saving agricultural extension service system. Gradually form a water-saving agricultural policy system, technical system and working system, strengthen classified guidance, improve the optimal allocation of water resources and water production efficiency, and provide strong support for ensuring food security and changing agricultural development mode.
(6) development goals.According to the principle of optimized layout and overall promotion, during the "Twelfth Five-Year Plan" period, the National Modern Agriculture Demonstration Park was established and built nationwide.100A distinctive, large-scale water-saving agricultural core demonstration area, the new water-saving agricultural technology demonstration and promotion areaoneOne hundred million mu, irrigation water and natural precipitation production efficiency improved.10%. By vigorously developing water-saving agriculture, the overall goal of "one promotion, two alleviation and three improvement" will be realized, namely: promoting grain production and increasing farmers’ income; Alleviate the contradiction of water shortage in agricultural production and the threat of drought to agricultural production; Improve water productivity, improve agricultural drought resistance and disaster reduction capacity, and improve the comprehensive production capacity of cultivated land.
(7) Basic principles.Based on the field, comprehensive support. The key link of water-saving agriculture is in the field, and grasping farmland water-saving will grasp the foundation of water-saving agriculture. Strengthen the integrated application of engineering, equipment, agronomy, biology, chemistry and management measures in the field, and establish a comprehensive water-saving technical system of "storage-collection-protection-saving-use". Highlight key points and demonstrate. Highlight the key areas, main promotion modes, leading crops and key technologies of water-saving agriculture, strengthen integrated assembly, demonstration and radiation-driven, strive to produce scale effect, and gradually form a new pattern of water-saving agriculture with obvious benefits and unique characteristics. According to local conditions, classified guidance. According to the situation of water resources, crop distribution and farming system, the development plan and work plan of water-saving agriculture are formulated according to local conditions. According to the type of cultivated land soil, climate characteristics, water demand law of crops, etc., strengthen classification guidance and scientific management. Government-led, multi-party participation. Give full play to the leading role of the government in developing water-saving agriculture, strengthen policy support and capital investment, co-ordinate a number of resources, and give full play to the comprehensive effect of project funds. Encourage enterprises, farmers and all sectors of society to actively participate, and form a good situation of promoting the development of water-saving agriculture at multiple levels and through multiple channels.
Third, determine the regional main push technology model according to local conditions
To develop water-saving agriculture, it is necessary to integrate key technologies, make clear the main mode and achieve key breakthroughs.
(eight) the "three North" regional technology model.The northwest, north China and northeast China are seriously short of water resources, with less precipitation and large evaporation. Drought and water shortage have become the main bottleneck of agricultural development, and the annual output fluctuates greatly due to drought. These areas actively develop corn, potatoes, cotton and other staple crops mainly by popularizing and applying water-saving agricultural technologies. In areas without irrigation conditions, water storage and moisture conservation should be carried out simultaneously, and soil reservoirs should be built through conservation tillage, subsoiling and soil improvement to improve water storage and water conservation capacity; Rational development of drought-resistant small water sources, popularization of drought-resistant sowing with water, scientific application of drought-resistant agents and water-retaining agents to solve the problem of drought-resistant seedlings in spring; Vigorously promote plastic film and straw mulching technology to achieve rainwater harvesting and moisture conservation; In areas with irrigation conditions, we will vigorously develop high-efficiency water-saving technologies such as drip irrigation under film, micro-irrigation, sprinkler irrigation, rainwater harvesting and supplementary irrigation, water and fertilizer integration, and water-saving mechanization in dry farming.
(9) Technical model of main wheat producing areas in Huanghuaihai.The resource water shortage and engineering water shortage coexist in the main wheat producing areas of Huang-Huai-Hai, water shortage and waste coexist, flood irrigation is more common, groundwater is seriously over-exploited, and the contradiction of water use is increasingly prominent. The key point is to popularize soil moisture measurement and irrigation saving technology, improve irrigation system and optimize water delivery and irrigation methods. Through the monitoring of soil moisture, the irrigation scheme is scientifically formulated, and the technical modes such as "Xiaobailong" water conveyance, "Little Dilong" sprinkler irrigation and changing long border into short border are mainly popularized and applied. Focus on the production of horticultural crops such as fruits and vegetables, and vigorously promote the integration technology of micro-irrigation and fertilizer. In suitable areas, conservation tillage should be implemented, and soil moisture conservation measures such as subsoiling and suppression, hoeing and mulching should be adopted to improve soil moisture storage capacity.
(10) Technology model in southern China.The precipitation in southern China is abundant, but the spatial and temporal distribution is uneven, and the terrain is complex, and the engineering water shortage is more prominent. In recent years, the frequency of seasonal drought is getting higher and higher, and the threat of drought and water shortage to agricultural production is increasing. In seasonal arid areas, the key points are to strengthen the construction of slope to ladder, field rainwater collection, irrigation and drainage facilities, and enhance the capacity of water storage and water transfer. Around corn, potatoes and other crops, technologies such as plastic film mulching, biological mulching and rainwater harvesting and supplementary irrigation are mainly promoted. Develop efficient water-saving technology with modern micro-sprinkler irrigation and water and fertilizer integration as the core on economic horticultural crops. Popularize techniques such as shallow wet and thin sun irrigation and controlled irrigation in paddy fields to promote the coupling of water and fertilizer.
Four, earnestly do the key work of water-saving agriculture.
During the "Twelfth Five-Year Plan" period, agricultural departments at all levels should base themselves on the existing foundation and promote the development of water-saving agriculture from the aspects of facility construction, technology popularization, rational planting and scientific drought resistance.
(eleven) to strengthen infrastructure construction.Seize the favorable opportunity that the state attaches great importance to farmland water conservancy construction, integrate resources and strengthen the construction of water-saving agricultural infrastructure in the field. Combined with the construction of high-standard farmland, we will strengthen the construction of cultivated land quality, improve the guarantee conditions of farmland water sources, and form a new pattern of water-saving agriculture integrating storage, protection, collection, saving and use. In combination with the organization and implementation of projects such as the field project of adding 100 billion Jin of grain production capacity nationwide, the demonstration project of dry farming water-saving agriculture and the popularization of dry farming science and technology, we will strengthen the construction of water-saving micro-projects and supporting facilities in the field and improve the ability of farmland to store water and preserve moisture. Combined with farmland water conservancy construction and comprehensive agricultural development, we will comprehensively improve the ability of farmland to resist disasters and reduce disasters and continuously increase production of cultivated land.
(twelve) to speed up the demonstration and popularization of technology.Carry out in-depth demonstration activities of water-saving agriculture and establish a demonstration platform. Make full use of platforms such as the establishment of high yield of grain, cotton, oil and sugar and the establishment of horticultural crops standard garden, highlight superior crops according to the production conditions, resource characteristics and farming systems in different regions, strengthen the construction of farmland water-saving demonstration areas, integrate and demonstrate a number of new simple and practical water-saving technology models, and carry out the popularization and application of water-saving technology and equipment. Pay close attention to technical experiments and demonstrations, so that there are demonstrations in counties and villages, and the scale of demonstrations is constantly expanding. Strengthen the cultivation of demonstration subjects, focus on supporting, serving and guiding large grain producers, science and technology demonstration households and professional cooperatives, set an example, drive surrounding farmers, and effectively play the role of demonstration.
(thirteen) the implementation of adaptive planting methods.According to the situation of water resources in different regions, make overall planning, rationally arrange crop planting structure because of water layout, and promote the sustainable utilization of water resources. Adjust and optimize the structure of planting crops and varieties, make full use of natural rainfall, synchronize the water demand period of crop growth with the rainy season, and change passive drought resistance into active drought avoidance. Cultivate and popularize high-yield and drought-tolerant varieties, improve farming and cultivation systems, improve crop water use efficiency, and achieve the goals of saving water, increasing production and increasing efficiency.
(fourteen) do a good job in scientific drought relief.Make overall plans, plan ahead for a rainy day, study and formulate emergency plans for drought relief, actively prepare for drought-resistant technology, materials, work organization and operation mechanism, and improve the ability to cope with drought. Establish and improve the network system of soil moisture monitoring, make full use of modern information technology, optimize monitoring methods, and improve the timeliness, pertinence and scientificity of soil moisture monitoring. Improve the information release mechanism and provide scientific basis for agricultural production and drought relief in time.
Five, constantly strengthen the safeguard measures for the development of water-saving agriculture
(15) Strengthen organizational leadership.Agricultural departments at all levels should fully understand the great significance of developing water-saving agriculture in safeguarding national food security and transforming agricultural development mode, earnestly strengthen organizational leadership, conscientiously perform the responsibility of "developing water-saving agriculture by using engineering facilities, agronomy, agricultural machinery, biology and other measures", develop and expand the professional team, promote the construction of water-saving agriculture system, and provide organizational and institutional guarantee for accelerating the development of water-saving agriculture.
(16) Increase investment.Strengthen communication and cooperation with relevant departments, integrate resources, form a joint force, and establish an investment mechanism with government as the leading factor and social participation.
