The average altitude of Ali is more than 4,500 meters, the average annual precipitation is only about 75 mm, and the oxygen content is less than 50% of that in the mainland. It is a medically recognized "life forbidden zone" that is not suitable for human habitation. The crowd joked that Ali has only two seasons in a year: winter and around winter. The cold and oxygen-deficient environment makes it difficult for many plants to survive, and it is even more unimaginable to grow vegetables and fruits.

For a long time, the vegetables and fruits that people living here eat mainly come from Xinjiang and other places thousands of miles away, and the high freight rate keeps the price of vegetables high. It is difficult and expensive to buy food, which has long plagued the local government and greatly affected the people's sense of gain.

The Gaer County Party Committee and the county government have successively invested nearly 100 million yuan to build a modern facility agricultural park integrating vegetable planting, experimental demonstration, scientific and technological training, planting and breeding cycle and other functions. The industrial park introduced domestic advanced facility planting technology, and built 6.5438+0.2 million square meters solar greenhouse, five-film arch shed and intelligent linkage greenhouse, and finally planted high-quality and high-yield flowers, vegetables and fruits in the plateau area.
