摘 要:Our country is a big country with traditional agriculture, and agricultural production plays a vital role in our socialist construction. Since the founding of New China, China's grain output has continued to increase, but the problem of irrigation water behind the increase in grain output has become increasingly prominent. China is a country with a large population and a large population, but it has less water resources. With the rapid development of cities, water use in cities and industries is increasing year by year. The allocation of water resources is becoming more and more prominent. The "flood irrigation" method used in traditional agricultural irrigation obviously does not meet the water demand of today's society. Based on this, this paper analyzes the level and trend of agricultural water use from the perspective of farmland irrigation quota and reasonable allocation of water demand, so as to better develop and utilize water resources.
关 键 词:farmland irrigation QUOTA rational development configure
