First, let's learn about the origin of asparagus. Asparagus originated in the eastern Mediterranean and Asia Minor, and was introduced to America in the17th century, to Japan in the18th century, and to China in the early 20th century. It is cultivated all over the world, with the largest in the United States. China has been planting asparagus since the Qing Dynasty, with a history of 100 years. ?
Due to the market demand, the good environment in China is suitable for the growth of asparagus, so although the planting history of China is only 100 years, the output is increasing year by year. At first, Taiwan Province Province planted the most asparagus and exported the most. Later, Henan, Fujian, Sichuan and other places began to grow asparagus on a large scale, and the export volume soared. Among them, Shandong is the main base of asparagus production, accounting for a large proportion of asparagus exported nationwide. Shandong got its name from this? The land of asparagus? This shows the status of Shandong asparagus. China's asparagus exporting countries are mainly the United States, Japan, Europe and other countries. ?
It can be seen that China produces the most asparagus for export, the demand for asparagus abroad is increasing, the price is getting higher and higher, and the export volume of China is also increasing. At present, China's asparagus industry has developed into a new industry with international competitive advantages, and its planting area and output rank first in the world. I believe that the development prospect of asparagus will be better and better in the future. Therefore, if someone wants to grow asparagus, Bian Xiao thinks he can try, but he must find a good partner and know the technology to avoid loss.
