In pics: Cutting-edge tech employed in Yunnan flower greenhouse

In Jinning district, central Yunnan’s Kunming city, lies China’s largest smart greenhouse for soilless cultivation of fresh-cut roses—the Yuntianhua demonstration park for modern flower industry. The greenhouse covers some 1,00 hectares.

Here, the roofs automatically open or close in accordance with the light, heat, humidity, and CO2 conditions. A precision drip irrigation system delivers nutrient solutions containing 17 elements for the roses. Automated sorting and packaging systems boost labor efficiency by 30%.... Let’s take a closer look.
