CCTV news: March 22 is the 34th "World Water Day", and the 39th "China Water Week" also opens simultaneously. The latest data from the Ministry of Water Resources shows that my country has built the world's leading national water network. Compared with the world's advanced level, my country's water efficiency has changed from a follower to a current leader, and some fields and regions have even reached the leading level. Smart farms “sense” the environment and automatically develop irrigation strategies.
Agricultural production is one of the largest consumers of water. The addition of new technologies allows every drop of water to fully realize its value. In a smart farm in Hangzhou, Zhejiang, the 450-acre field is equipped with more than 200 field sensors and 4 IoT micro base stations, which can automatically determine the amount of irrigation and the corresponding time based on the growth attributes of rapeseed, combined with the soil moisture, field size and real-time water level monitored by the sensors. In the greenhouse nearby, the lush green kale is growing happily. New aerosol cultivation technology is introduced here, using nutrient solution instead of soil. The system can automatically formulate irrigation strategies based on light, temperature, humidity, and crop growth stage, and accurately regulate the spraying frequency of nutrient solution to ensure that crops receive timely and appropriate amounts of water. AI decision-making for water supply makes mountain blueberry irrigation smarter. In a blueberry base in Beichuan, Sichuan, the AI smart water-saving irrigation system loads soil, water, fertilizer, and meteorological data into the "smart brain", transforming traditional mountain agriculture from "watering based on experience" to "AI decision-making for water supply," allowing hilly and mountainous areas to develop modern agriculture that saves water and electricity.

After fully applying AI smart irrigation in this 1,800-acre orchard, the total annual water saving exceeds 90,000 cubic meters, the annual electricity and labor costs are saved by more than 400,000 yuan, and the water and fertilizer utilization rate is nearly doubled. Propaganda reaches people’s hearts and enhances the public’s awareness of water conservation.
Another major factor in improving water efficiency is the increasing public awareness of water conservation. On March 22, various publicity activities were held in various places, and water-saving knowledge was organized and carried out in schools, communities, and business districts to guide the whole people to participate in water resource protection. At the promotional event site in Weihai, Shandong Province, the organizers set up interactive water-saving experiences, knowledge questions and answers, and initiative signatures to allow citizens to learn practical water-saving methods and further strengthen their awareness of loving and protecting water. City Water Plant Opens to Understand the "Past and Present Life" of Tap Water.
