Over the past decade, China's vegetable production has increased and has always been the world's largest. Thanks to the six large key vegetable production areas and technologies such as greenhouse and vegetable breeding, China now can provide its 1.4 billion people with fresh vegetables all year round, despite the country's diverse land and weather conditions.
In Mohe, China's northernmost city winter temperatures can reach below minus 40 degrees Celsius. In western China's Tuokexun, there are only nine days of rainfall on average each year. The Qinghai-Tibet Plateau in southwest China has an average elevation of more than 4,000 meters.
Despite its diverse land conditions, 1.4 billion Chinese people are still able to eat vegetables all year round. So how does China provide vegetables to its population all year round?
In northern China, temperatures drop rapidly in autumn and soil gradually freezes in winter and outdoor plants cannot be grown for five to six months. But science and technology have solved this problem.
