In Jiangdian township in Gaotang County, Hebei province, a special hotline was set up in 2019 for farmers to provide agricultural technical support to each other and address questions and difficulties they encounter, a local media outlet reported.
The person behind the hotline is Zhang Caiyun, head of the agricultural technology station in Jiangdian and a member of Du Lizhi's agricultural technology office.
Seeking assistance from the Caiyun hotline is now common among the farming community in the township.
"With the guidance of a specialist, I feel more confident in growing greenhouse vegetables," said farmer Zhu Aibin, whose tomato greenhouses have benefited from Zhang's expertise.
Though Zhu had spent years growing greenhouse tomatoes, most of his fruits were of lower quality, categorized as second-grade. Feeling disheartened, he called the Caiyun hotline for help.
Upon learning about the situation, Zhang promptly arrived at Zhu's greenhouse to offer advice. She discovered that the temperature of the greenhouse was too low, hindering the growth of the tomatoes.
