China: Greenhouses heat up thanks to 'intelligent' temp control system

In order to meet agricultural electricity demands, State Grid Changle County Power Supply in Weifang, Shandong province, organized an innovation workshop, headed by Zhang Aiguo and Ge Yuting to develop an intelligent temperature control system for greenhouse usage.

Working together with the county's labor union and agriculture bureau, they noticed that the low soil temperature in winter greenhouses could affect crop growth and severely reduce the added value of agricultural products. Addressing the problem, the system can monitor the soil temperature in real-time through sensors installed underground and then automatically adjust the soil temperature to help it remain at around 20 degrees Celsius.

The intelligent system has provided better conditions for vegetable and fruit planting to achieve higher yields and benefits, bringing stable income and employment opportunities for many local residents.

In the planting base, rows of greenhouse structures are arranged in order. While inside the greenhouse, the temperature is very warm, with fist-sized small watermelons hanging on the vines, showing the vigorous growth and vitality within the greenhouse.
