When were the foods that were introduced to China through the Silk Road other than tomatoes, potatoes, and corn?

The two were introduced to China before 1628 for potatoes and 1531 for corn.

1. Potato

Before the 17th century, the potato had become an important food crop in Europe and had already spread to China. Xu Guangqi (1562-1633) wrote "The Complete Book of Agriculture and Politics" (農政全書), in which "potato" was recorded. In the "full book of agricultural politics" volume 28 recorded the following paragraph: "potato, a potato, a yellow alone; trailing leaves like beans, root round as a chicken egg, inside the white skin yellow, ...... boiled, can also be steamed; and boiled taro juice, wash greasy clothes, white as jade."

From this it can be seen that the introduction of potatoes in 1633 years ago, no doubt; more accurately, the potato in 1628 years ago has been introduced into China, and widely known, commonly planted, because 1628 for the "agricultural policy book" published roughly time.

2, corn

According to the records of provincial general records and county records, corn was first introduced to China in Guangxi in 1531, less than forty years after Columbus discovered America (1492). By the end of the Ming Dynasty (until 1643), it had spread to Hebei, Shandong, Henan, Shaanxi, Gansu, Jiangsu, Anhui, Guangdong, Guangxi, Yunnan and other ten provinces. There are also Zhejiang and Fujian provinces, although the Ming Dynasty Fangzhi did not record, but there are other documents to prove that in the Ming Dynasty has been cultivated corn.

On the record alone, from 1531 to 1718 less than two hundred years period, corn in China has spread to twenty provinces.
