Harvesting the future

For example, a positive pressure air supply system has been installed.

It allows temperature and humidity adjustment in the greenhouses, so everything remains on an even keel, Geng explains.

The green room ceiling is made of diffuse reflective glass, which enables up to 97 percent of light transmittance, as opposed to 85 percent in traditional ways, and thus efficiently raises the photosynthesis effects.

Nutrition liquids are concocted and applied to the plants by an automated and smart farming system.

"The water and nutrition ratio has been optimally figured out and how much liquid each vegetable needs is precisely controlled by computer, based on real-time sunlight and the growth phase," Geng says.

The Xiangjiadang agriculture digitalization plant is expected to provide 1 million kilograms of premium green vegetables and offer job opportunities to about 500 local farmers, according to the local authority.

"We can offer 58,000 yuan a mu to the government over the next 12 years," Geng says, adding that local farmers can get land rental and income from working here.
