"The weather is hot, and the roadside trees are wearing 'swimming rings'. It's really strange!" Recently, Mr. Gao, a citizen, passed by the Beijing Tianqiao Art Center and was attracted by the roadside trees. The blue "swimming ring"-like devices were put on the roots of the trees, which looked quite fresh.

"It's the first time I've seen such a device. I wonder what it's used for?" Mr. Gao took a photo and posted it on social media, sparking the curiosity of many netizens. Following Mr. Gao's instructions, the reporter came to Tianqiao South Street in Xicheng District and saw that the roots of more than 20 roadside trees on the roadside east of Beijing Tianqiao Art Center were covered with this device. The outer layer of the device is a blue plastic shell, and the inside is a black rubber hose. There is a water pipe on each side connected to the underground pipeline, and a valve on one side.

The reporter later learned thatIt turns out that the device is a new "smart drip irrigation" technology used in the Xicheng District's roadside tree rejuvenation and salt-damaged tree replanting project.As early as 2021, it was put into use in areas such as the Financial Street. It was the first of its kind in the city's garden maintenance and has been gradually promoted throughout the district in the past two years. The intelligent drip irrigation equipment uses water storage equipment and directional pipes for infiltration irrigation. The infiltration head slowly infiltrates water one meter below the surface under the action of gravity. There is no sun evaporation or wind volatilization in the middle. The infiltration is concentrated at fixed points, and the utilization rate can reach more than 90%. At the same time, nutrient solution and related drugs for the prevention and control of diseases and insect pests can be added to the water for efficient use.

In addition, the water storage part of this infiltration irrigation equipment has many other appearance styles, which can be beautifully integrated with the environment. It is a new, scientific and efficient equipment.In addition to street trees, it can also be used in other greening projects where water is scarce or watering is inconvenient or requires unattended operation, flower cultivation, crop breeding, etc.
