ROro reverse osmosis report: At present, the total water consumption in China has already increased by 60 million cubic meters, accounting for 74% of the comprehensive utilization of water sources. However, the water shortage in various parts of the country still exceeds 50 billion cubic meters; The average and per mu water resources are 2100 cubic meters and 1400 cubic meters respectively, which are only 28% and 50% of the global average. This series of data indicates that China is a country with water resource pollution. Among the total water consumption of over 600 billion cubic meters, China's agricultural water consumption reached 37.9 million cubic meters last year, accounting for 62% of the total water consumption in various parts of the country. Agriculture is undoubtedly the first major water user.

ROro Reverse Osmosis Report: According to calculations, at the current stage in China, the amount of water used by enterprises for grain production is not enough to reach 1.2KG/cubic meter. A volume of 1 cubic meter of water with a quality of 1000KG. After simple calculation, it was found that the water consumption for producing 1kg of grain in China reached 800KG. Let's discuss the global excellent level again. The water consumption for grain production in enterprises is around 2KG/cubic meter, and the water consumption for producing 1kg of grain is about 500KG. The significant difference also indicates from another perspective that there is great potential for agricultural water-saving development in China. Over the years, outstanding achievements have been made in the basic construction of agricultural water conservancy and irrigation infrastructure in China, making remarkable contributions to increasing grain production and generating income for farmers. Little did they know that everyone still needs to recognize the reality of having a large amount of "debt" and basic weakness, especially the problem of being "constrained by others" one kilometer behind the irrigation and drainage of farmland is very prominent. The irrigation channel next to Yang Yuting's house in Liaoqiao Village, Malianqu Township, Gansu Province was built and protected last year, and the neat waterproof layer replaced the winding soil channel. "The seepage of the earthen canal is too severe, and before the water flows to the crops, it consumes up to half of it. The water cannot keep up, and planting grains can only be done blindly, resulting in low production." Yang Yuting said. The imperfect and incomplete methods have caused water to come out of river sections and branch canals, and before it reaches the ground, it has already been damaged, leaked, and evaporated in the final level canal system.

At present, the reasonable utilization rate of agricultural irrigation water in our country is only 0.51, which refers to the ratio of the amount of water used to irrigate crops in the fields to the total amount of drainage channels. The global excellent level is about 0.7 to 0.8. The basic shortage of water conservancy irrigation in farmland results in severe water consumption for irrigation. In addition, the current agricultural water use methods in China are still relatively extensive, and the economic benefits of water source utilization are not high. On the one hand, the practice of flooding still exists in some areas. On the other hand, the marketing and promotion of agricultural water-saving technology is relatively backward. According to a survey, the total area of water-saving irrigation in China's 9.05 arable land red line is only 430 million mu, which is less than half of the proportion. High efficiency and water-saving irrigation techniques such as sprinkler irrigation equipment and irrigation are considered reasonable methods to improve water source utilization and economic benefits. At Hongji Farm in Ranghulu District, Baishan City, Heilongjiang Province, the subsurface drip irrigation equipment has been in use for 5 years. Deputy factory director Zhang Chaofu roughly calculated: one acre of corn (2362, -4.00, -0.17%), if using infiltration irrigation, the annual water consumption is about 200 cubic meters, while using subsurface irrigation only requires 30 cubic meters. Under film irrigation allows water to immediately infiltrate the growth and development areas of grain crops through fine pipelines. With less water, production can be significantly increased. Little did they know that in China, the total area of high-efficiency water-saving irrigation is less than 200 million acres. To reduce the consumption of irrigation water and improve the utilization rate of water infiltration, the development potential of agricultural water-saving in China must be explored through "frugality and frugality".

ROro Anti Osmosis Report: In response to the anxiety and anxiety of water sources, China has clearly proposed the implementation of stricter water resource management regulations. By 2015, the total water consumption in various parts of the country will strive to be controlled within 63.5 million cubic meters; The reasonable utilization rate of agricultural irrigation water has been increased to 0.53. By this year, the total amount of water used across the country is expected to be controlled within 67 million cubic meters; The reasonable utilization rate of agricultural irrigation water has been increased to above 0.55. This kind of "hard and particularly good" has put forward new regulations for agricultural water conservation. To achieve this overall goal, it is necessary to use engineering project methods. For the current problems such as poor supporting facilities for irrigation and drainage equipment, embrittlement and disrepair, and economic efficiency attenuation coefficient, China will focus on implementing the expansion of supporting facilities and water-saving renovation for large, medium, and small irrigation projects, as well as upgrading and renovating irrigation and drainage sewage treatment plants. By 2015, we will carry out daily tasks for the expansion of supporting facilities and water-saving renovation for 190 large, medium, and 800 key small and medium-sized irrigation projects. In addition, we will do a good job in the basic construction of demonstration counties for water conservancy and irrigation in small and medium-sized farmland, and enhance the basic construction of water conservancy and irrigation infrastructure in small and medium-sized farmland, with high efficiency and water-saving irrigation engineering projects, intelligent irrigation and drainage canal systems, "Five Small Water Conservancy Engineering" engineering projects, precipitation collection and utilization engineering projects, and field irrigation and drainage "one kilometer later" as the key.

ROro Reverse Osmosis Report: In addition, China will also vigorously develop popularization and high-efficiency water-saving irrigation technologies. By 2015, the total area of water-saving irrigation projects will be increased by more than 150 million mu, with a guaranteed increase of 0.5 billion mu in the total area of high-efficiency water-saving irrigation and efforts to increase it by 100 million mu. In 2020, the Ministry of Water Resources of China, along with the Ministry of Finance, the Ministry of Agriculture and other units, launched a water-saving and grain increasing campaign in the four provinces and regions of Northeast China. The plan will take four years to develop a total area of 3800 square kilometers of high-efficiency water-saving irrigation projects, improving the comprehensive production of grains and the high efficiency of agricultural irrigation water. Little did they know that agricultural water-saving is not only a challenge in engineering design, but also a challenge in management methods.

ROro Anti Osmosis Report: During interviews in Shandong Province, Shanxi Province, and other places, it was observed that many villages have already implemented the original method of water rights allocation, implementing total amount control quota management for irrigation water. Farmers use IC cards to purchase water for irrigation first, and the water flow purchased within the scope of water rights allocation belongs to themselves, and can be freely sold among industry businesses. In the future, China will gradually improve the rules and regulations for controlling the total amount and quota management of agricultural irrigation water, enhance the basic construction of water measuring equipment, and improve the collection methods of water and electricity fees. With excellent management mechanisms and appropriate use of financial leverage, we will continuously strengthen the self-awareness of farmers in water conservation. In recent years, Gansu, Inner Mongolia Autonomous Region and other regions have carried out water-saving renovation of old irrigation projects in the Yellow River irrigation areas based on industrial investment, and the saved water flow is used for industrial production basic construction according to water rights transformation. Promoting the construction of water rights organizations and the cultivation of water sales markets is a beneficial attempt to enhance the initiative of agricultural water-saving and improve the allocation of water sources.
