BEIJING, Dec. 26 (Xinhua) -- When cold spells persisted in east China's Tai'an City recently, local grid operator Tai'an Power Supply Company helped high-tech agribusinesses access reliable power services to ensure winter vegetable supplies.
In Quangou Town of Tai'an City, the fish and vegetable symbiotic greenhouses, a characteristic and high-yielding mode of green agriculture developed by Zunhao Zhiyu Ecological Agriculture Development Co., Ltd., usually demand resilient and stable power supply.
Generally, every such greenhouse is equipped with a multiple sensors-based smart data sensing system to maintain a constant temperature both in summer and winter and suitable water and ultraviolet rays parameters to improve the quality and output of vegetables.
Under such circumstances, the greenhouses enable refined production of aquatic products and vegetables thus every segment of their data sensing systems is separable from electricity supply, according to Zhu Qinglai, deputy manager of Zunhao Zhiyu Ecological Agriculture Development Co., Ltd.
By establishing a special service team, Tai'an Power Supply Company under the State Grid Shandong Electric Power increased power patrols over the fish and vegetable symbiotic greenhouses.
Checking electric facilities such as water circulation pumps, ventilation systems and aerating devices within the greenhouses on a regular basis, Tai'an Power Supply Company helped guarantee that all these facilities could weather the low temperatures during the cold spells.
Apart from these, the company also formulated tailored power use solutions for these greenhouses to meet their concrete power needs, which, together with its power security lectures, largely contributed to their production expansion.
As a quintessential example of green agriculture, the resilient power supply-facilitated fish and vegetable greenhouses attracted people from near and far to learn from the characteristic innovation to further vitalize the rural economy there.
