In Nagqu, Tibet, where the average altitude is over 4,500 meters, the climate is dry, cold, windy, and low in rainfall. It is difficult for trees, vegetables, and fruits to grow and survive in such an environment. Although the development of the logistics industry has enabled people here to eat fruits and vegetables shipped from other places, it is the first time that local residents see such fresh local fruits and vegetables. The production of these fruits and vegetables is done by the Zhejiang Industrial Support Tibet Precision Poverty Alleviation Demonstration Base, with a multi-span smart greenhouse covering over 6 hectares.
The smart greenhouse covers an area of over 6 hectares and has a total investment of more than 70 million RMB [10 million USD]. The overall structure is composed of light steel, equipped with an automatic environmental control system, aeroponic cultivation system, water treatment system, and precise nutrient solution distribution system. "In order to meet the needs of high altitude and harsh environment, many of our equipment is specially customized. Such a modern greenhouse can be considered advanced even if it is located in Zhejiang," said Wang Dongsheng, the technical leader of the project construction.
Cucumbers, greens, lettuce, spinach, and tomatoes are planted neatly in rows on aeroponic cultivation racks. Looking at the fresh fruits and vegetables just picked and being packed and ready to be given to Tibetan residents, Jia Yongyi, an official of the project “Zhejiang Support to Tibet” also deputy director of the Nagqu Agriculture and Rural Bureau, was very pleased.
"We moved in in April, completed in June, planted in July, and harvested the first batch of fresh vegetables in August. In the future, the fresh fruits and vegetables produced here will be continuously supplied to the local people in Nagqu." Jia Yongyi said, the design and construction of the "smart greenhouse" come from Zhejiang, the talent team comes from Zhejiang, and the planting technology comes from Zhejiang.
Next, the smart greenhouse will also open plateau “oxygen bars”, ecological restaurants and other facilities, and gradually build the world’s highest altitude and largest modern smart greenhouse, integrating with facility cultivation, digital control, ecological recycling, Tibetan culture, agricultural tourism, science education and other functions in one.
