By widely promoting smart greenhouse farming, Qiongjie county in Shannan city, southwest China's Xizang Autonomous Region, has significantly increased its land productivity in recent years.

Operators of the greenhouses have adopted technologies to continuously improve the soil quality, closely monitor temperature and humidity inside the greenhouses, and effectively intervene in crop growing conditions. These have successfully transformed previously barren saline-alkaline land into highly productive vegetable and grain fields, according to Guan Dapeng, a manager of the greenhouses.

"Currently, our greenhouses covering an area of over 400 mu (26.67 hectares) produce more than 2 million kilograms of fruits and vegetables annually, providing convenient employment opportunities for nearly 200 locals," Guan said.
