Observe the hydrological conditions in this area. Terrain, so as to choose the appropriate irrigation method.
1. 1 When irrigation is irregular, we should also consider the cost-benefit ratio and the profitability of irrigation. If the cost of irrigation measures is increased, the benefits will be little, then this irrigation measure is not worth implementing, otherwise it will lead to a situation of "drawing water with a sieve".
Before planning 1.2, it is necessary to analyze the ratio of irrigated water source area to irrigated area. To make an irrigation plan well, we need to analyze all the factors that can be referenced, including the water demand of farmland, the water supply of water supply area, how to realize the balance relationship between them and so on.
1.3 planning also needs to pay attention to water saving. Although irrigation itself consumes a lot of water, every drop of water should be fully utilized to save water resources. After all, no one wants the last drop of water in the world to be the tragedy of human tears.
2, in the process of water conservancy project construction
In the process of water conservancy project construction, many facilities need to be built and many things need to be integrated and transformed. It is necessary to store water scientifically, and store a proper amount of rain when there is more rain or in flood season for use in case of drought; It is also necessary to build channels to dredge irrigation water and rivers to facilitate the circulation of water. Under the condition of complete equipment, the problem of irrigation water can be effectively solved.
3. In the process of implementing irrigation technology
In the process of implementing irrigation technology, there are many precautions that need to be reflected in the planning: regularly check the facilities with irrigation problems, and if any equipment with poor running speed is found to be less than half, it should be removed; Check the waterlogging prevention equipment, and if it is found that it does not meet the waterlogging prevention standards, it should be dismantled in time, and the reconstruction work should be carried out immediately after dismantling.
4. The significance of irrigation technology planning for water conservancy projects.
Planning irrigation technology of water conservancy projects can achieve good social effects and cater to the relevant policies of the state on agricultural issues. The establishment of water conservancy facilities convenient for irrigation can also improve the environment and prevent many farmers from recycling water without knowing the irrigation plan, which will cause serious damage to the land structure. After the completion of small-scale irrigation and water conservancy projects, the environmental, social and economic benefits of the planning area are very remarkable. The establishment of irrigation facilities can also reduce the waste of water resources and reduce soil erosion. It becomes easier for farmers to engage in agricultural work and their income increases, so the gap between the rich and the poor in society will be narrowed and social contradictions will be reduced. The establishment of these irrigation facilities can also effectively prevent waterlogging, protect the environment, reduce the possibility of people being harmed by disasters and purify the living environment in rural areas, which is of great significance to the further development of rural areas.
5. In order to better manage irrigation facilities, a perfect management system must be established.
At present, in order to strengthen the management of water conservancy facilities, the state has established a water conservancy project cooperation office. Its main responsibilities are: to formulate annual irrigation water plan and emergency water plan; Register all irrigation farmers, formulate annual irrigation water charging standards, and collect irrigation water charges from farmers. These collected fees are used for the restoration and reconstruction of water irrigation; Responsible for coordinating the water use of all farmers to avoid unnecessary disputes caused by large irrigation demand and limited water supply speed of irrigation facilities in dry season.
