At the Shangshantang substrate blueberry base of Shangshantang in Weihai, Shandong province, the plump and round blueberries are covered with a layer of misty white fruit frost, resembling large indigo pearls.
"We use a nutrient solution instead of nutrients in the soil, and a mixture of peat, coconut husk, and perlite as the growth medium for blueberries. By breaking away from the limitations of soil, we can precisely control the intake of substances needed for plant growth," said Gao Yong, production manager of the blueberry base, adding that the growth rate is two to three times faster than in soil, effectively improving yield and quality.
The entire greenhouse is equipped with intelligent drip irrigation, spray irrigation and temperature and humidity control systems. Through precise control, every blueberry can receive sufficient water and nutrients, nurturing the blueberries throughout their growth process, Gao said.
Cutting-edge high-tech is also applied at the base. With a few taps on the phone, real-time data on the pH value, water content, and environmental temperature of the blueberry substrate soil can be received.
