Analysis of water saving irrigation methods and advantages

Scientific irrigation is an irrigation method that professional irrigation enterprises have been promoting, including drip irrigation, micro spraying, infiltration irrigation, sprinkler irrigation and other modern irrigation methods. It is necessary to make reasonable design according to the water demand characteristics, growth stage, climate and soil conditions of corresponding plants, and formulate corresponding irrigation system for timely, appropriate and reasonable irrigation.

This kind of method can achieve local accurate irrigation. In addition to supplementing soil water to meet the needs of plant growth, it can also dissolve fertilizers and pesticides in water and carry out fertilization and pesticide spraying in combination with modern fertilization devices such as fertilizer injection pump. It can also avoid soil salinization. For the salinized soil, irrigation can be used to wash the soluble salt in the soil to improve the soil. In addition, scientific irrigation can also prevent frost of fruit trees and vegetables, dry hot wind hazards, and soil wind erosion.

Advantages of water saving irrigation

Scientific irrigation can effectively maintain the good state of water, fertilizer, gas and heat in the soil. It has many advantages such as water saving, labor saving, energy saving, fertilizer saving, increasing production and income, and is gradually recognized and used by everyone. However, due to the lack of funds and understanding, there is still a lot of work to be done by peers in the industry.

Since modern times, with the rapid increase of population and increasingly developed economy, the prominent contradiction between supply and demand of water resources has also been reflected in the worldwide irrigation industry. In addition, there are still some problems, such as further reducing construction and operation costs, improving irrigation benefits, and preventing salinization and swamping of irrigated land. There is a serious problem of soil salinization in Shouguang, Shandong, the hometown of vegetables in China.

On the other hand, at present, many water-saving irrigation projects have the serious problem of just building and not using. Many countries have shifted the focus of irrigation development from developing new irrigation areas to rebuilding old irrigation areas and strengthening irrigation management.
