　　In East China's Shandong province, winter date grower Guo Ning expressed a myriad of emotions while looking at the thriving winter jujube trees growing at the Guo Ning Winter Jujube Demonstration Park in Xiahe Town.

　　In order to usher in an early harvest of his winter dates and sell them for a good price, Guo has introduced “smart temperature control “technology to the greenhouses in the park, set up by the local township government with an investment of 1.6 million yuan ($221,270).

　　At Guo's demonstration park, a key industrial project in the town, controlling greenhouse temperatures is conducive to maintaining the activity of the root system and boosting the revival of seedlings in early spring, said Xu Lin, government head of Xiahe town in Zhanhua district.

　　In recent years, Zhanhua, which is part of the prefecture-level city of Binzhou, has vigorously developed its winter jujube industry and bolstered modern agricultural technology, helping jujube growers raise their income and become prosperous.

　　Zhanhua, sitting on the lower reaches of the Yellow River in northern Shandong, governs two sub-districts, seven towns and two townships with a total population surpassing 331,800.
