With the rapid development of China's economy in recent years, agricultural economy, as an important part of the national economy, has been paid more and more attention. The application of water-saving irrigation technology in farmland water conservancy construction can enhance the environmental protection of farmland water conservancy construction and effectively improve the economic benefits of farmers. Based on this, we should pay more attention to water-saving irrigation and adopt advanced water-saving irrigation technology to better improve agricultural production efficiency.

1, concrete application of water-saving irrigation technology in farmland water conservancy construction

1. 1 Application of sprinkler irrigation technology

From the current situation, sprinkler irrigation technology is the most widely used form of water-saving irrigation technology. Sprinkler irrigation technology refers to transporting water resources to farmland through pipelines and internal pressure, and spraying water resources evenly on the surface of crops, which not only ensures uniform irrigation of crops, but also saves water resources to some extent. Generally speaking, sprinkler irrigation technology can ensure that more than 90% crops are irrigated evenly; Compared with the previous flood irrigation technology, sprinkler irrigation technology effectively improves the utilization rate of water resources, saving water by about 50%, and fundamentally avoids the waste of resources. In addition, sprinkler irrigation technology can also reduce the input of labor costs. Because of its high working efficiency and even crop irrigation, the labor intensity of growers is reduced.

Application of 1.2 micro-irrigation technology

Micro-irrigation technology is a water-saving irrigation technology developed on the basis of drip irrigation technology, including infiltration irrigation, drip irrigation, micro-sprinkler irrigation and other forms. Compared with other water-saving irrigation technologies, micro-irrigation technology can directly transport water resources to the roots of crops, accurately control water consumption, and then form local irrigation, so it requires less water and effectively saves water resources. In addition, micro-irrigation technology can also integrate fertilizer and water to irrigate crops, which reduces labor costs to some extent. However, before micro-irrigation technology, it is necessary to establish a perfect water distribution network to ensure the rational distribution of water resources, so it has the disadvantages of long time consumption and short irrigation cycle, and cannot be applied to all types of crops. At present, micro-irrigation technology is widely used in the planting process of cash crops and protected crops to better improve the economic benefits of crops.

1.3 Application of Walking Irrigation Technology

Walking irrigation technology is a water-saving irrigation technology developed for farmland in urgent need of irrigation, which can effectively meet the irrigation needs of some farmland. Walking irrigation technology is to combine the corresponding irrigation equipment with the agricultural machinery used in farmland planting at present to carry out mobile irrigation on farmland. Therefore, walking irrigation technology can effectively combine agricultural mechanization technology with water-saving irrigation technology, and both of them can improve the mechanization degree of irrigation work through simple assembly and configuration, thus improving the efficiency of agricultural planting and production. In addition, for the farmland in urgent need of irrigation, the hand-held irrigation technology does not require too complicated operation technology and repair works, which can not only save water resources better, but also reduce costs and effectively improve the quality of farmland water conservancy construction.

1.4 application of low-pressure pipeline irrigation technology

Low-pressure pipeline irrigation technology refers to water-saving irrigation technology that transports water resources to farmland through pressure irrigation system. Low-pressure pipeline irrigation technology is applied by more and more growers because of its convenience, rapidity and high efficiency. At the same time, low-pressure pipeline irrigation technology can effectively improve the utilization rate of water resources, reduce the loss of water resources during evaporation, avoid the waste of resources to a certain extent, and promote the sustainable development of agriculture in China. In addition, compared with open channel irrigation technology, adopting low-pressure pipeline irrigation technology in canal irrigation area can effectively reduce the loss caused by water resources during transportation and reduce the occupied area of channels, which not only greatly improves the land utilization rate, but also strengthens irrigation technology and farmland management, so that the farmland water conservancy construction area can develop on a large scale [1].

2. The role of water-saving irrigation technology in farmland water conservancy construction.

2. 1 Improve the environmental protection of farmland water conservancy construction

The main purpose of using water-saving irrigation technology in farmland water conservancy construction is to reduce the waste of water resources, improve the utilization rate of water resources, and then better complete agricultural production. Based on this, water-saving irrigation technology can make scientific and reasonable planning and utilization of water resources, and further improve the efficiency and quality of farmland water conservancy construction. In addition, water resources, as a kind of resources that all countries in the world pay more attention to at present, are indispensable for both production and life, so the use of water-saving irrigation technology in farmland water conservancy construction can also alleviate the pressure of water resources in China to some extent, which is in line with the strategy of sustainable development of resources in China; At the same time, it can also protect and improve China's water quality, further promote the recycling ability and conservation ability of water resources, and effectively improve the energy conservation and environmental protection of farmland water conservancy projects.

2.2 Improve agricultural production efficiency

Water-saving irrigation technology includes sprinkler irrigation technology, micro-irrigation technology, walking irrigation technology and low-pressure pipeline irrigation technology, which can be adjusted scientifically and freely according to the irrigation needs of crops. On the one hand, it improves the utilization rate of water resources and effectively avoids the waste of water resources. On the other hand, water-saving irrigation technology can better meet the irrigation needs of crops, irrigate crops more reasonably according to the growth, environment, climate and other factors of crops, so as to cultivate crops more scientifically, create a good growth environment for crops and avoid the adverse effects brought by irrigation, thus improving the production efficiency and quality of crops to a certain extent and further promoting the efficient and long-term development of China's agricultural undertakings.

2.3 improve economic efficiency

The traditional irrigation method in farmland water conservancy construction not only needs to invest a lot of manpower and material resources, but also has problems such as low efficiency and economic benefit, which makes the input and income of growers disproportionate, not only consumes a lot of money and energy, but also wastes water resources, which hinders the process of farmland water conservancy construction to some extent. Based on this, the application of water-saving irrigation technology in farmland water conservancy construction can carry out automatic and technical irrigation work through advanced mechanical equipment, which can not only make full use of water resources, but also reduce the labor intensity of growers, so that growers can disperse their labor force into other agricultural production activities, thus improving agricultural production efficiency, effectively increasing the economic benefits of growers and promoting the further development of farmland water conservancy construction in China.

3. Optimization strategy of water-saving irrigation technology in farmland water conservancy construction.

3. 1 Improve the importance of water-saving irrigation.

In order to fundamentally improve the water-saving irrigation technology in farmland water conservancy construction, we must first strengthen the growers' attention to water-saving irrigation. As growers are the participants and beneficiaries of the whole farmland water conservancy construction, their water-saving consciousness affects the use effect of water-saving irrigation technology to a certain extent. For example, in the construction of farmland water conservancy, the use of micro-jet energy-saving irrigation technology in water-saving irrigation technology can better reduce the waste of water resources and reduce the damage to the ecological environment; At the same time, because the micro-jet energy-saving irrigation technology can make the farmland irrigation work more automatic and mechanized, so that the growers' work is simpler and faster, and the growers' attention to water-saving irrigation is further improved, so that they can fully participate in the farmland water conservancy construction [2].

3.2 Combination of water saving and water preparation.

Because the water-saving irrigation technology in farmland water conservancy construction in China is not perfect at present, it is necessary to strictly control the whole process of crop irrigation, and then fundamentally improve the effectiveness of water-saving irrigation technology. At present, most water-saving irrigation projects pay more attention to water saving, but ignore the importance of water distribution. Based on this, in order to better improve the water-saving irrigation technology in farmland water conservancy construction, it is necessary to effectively combine the water-saving link with the water distribution link. For example, when irrigating crops, growers should pay more attention to water pipes, adopt efficient and reasonable water-saving irrigation technology, further improve the water distribution link and improve the water distribution effect, so as to better realize the purpose of saving water resources and improve the effectiveness of water-saving irrigation technology to a certain extent.

3.3 Adopt scientific water-saving irrigation technology

Due to the large planting area in China, there are certain differences in climate, water resources and land resources in different planting areas. Therefore, scientific water-saving irrigation technology should be adopted in farmland water conservancy construction to irrigate crops more reasonably. On the one hand, growers should choose suitable water-saving irrigation technology according to the climate of crop planting areas to provide better growth environment for crops. On the other hand, according to the hydraulic resources in the planting area, growers should rationally plan the irrigation methods of crops and effectively improve the utilization rate of water resources. For example, for Jinan, Shandong Province, the productivity of most crops is relatively high, and growers can use the pressurized water pump power machine for irrigation, which better improves the efficiency and quality of irrigation work, thus enhancing the economic benefits of crops and improving the utilization rate of water resources.

3.4 Strengthen publicity work.

The application of water-saving irrigation technology in the construction of farmland water conservancy projects can effectively combine modern irrigation technology with the actual irrigation demand of crops, thus better improving the production efficiency and quality of agriculture and further promoting the stability and long-term development of China's agricultural undertakings. Based on this, we should strengthen the propaganda work of water-saving irrigation technology and continuously introduce advanced technology, so as to better carry out the construction of farmland water conservancy projects. For example, relevant units can organize publicity lectures regularly to let growers fully understand the advantages of water-saving irrigation technology; It can also let growers experience water-saving irrigation equipment and let them know the important role of water-saving irrigation technology in the construction of farmland water conservancy projects.

3.5 Strengthen the maintenance of water-saving system.

The effective maintenance and management of water-saving system can promote the sustainable development of farmland water conservancy construction and further promote the growth of agricultural technology in China. However, due to the inadequate maintenance and management of water-saving system, there are many problems in farmland water conservancy construction, which hinder the development of water-saving irrigation technology. Based on this, relevant units should establish a strict management system and strengthen the maintenance and management of water-saving systems. For example, the most important link in the water delivery system is anti-leakage treatment, but the workflow of technicians is not standardized, which leads to the lack of stability of the water delivery system. Therefore, the relevant units should establish a strict supervision mechanism, standardize the workflow of technicians, and make the anti-leakage treatment work more perfect [3].

4. Conclusion

To sum up, the application of water-saving irrigation technology in farmland water conservancy construction can not only bring more income to farmers, but also further promote the development of China's agricultural economy. Therefore, it is necessary to continuously strengthen propaganda work and improve people's attention to water-saving irrigation; It is also necessary to adopt scientific water-saving irrigation technology, combine water-saving links with water distribution links, and strengthen the maintenance and management of water-saving systems.
