明时玉米和红薯传入中国，清初传入土流并存的广西，但是两者在广西的传播、推广境遇却有很大的不同：玉米传播迅速，种植面积较大，成为山区主要粮食作物，而红薯传播速度较慢，种植面积不大。究其原因，学界有人提出主因是广西在清朝嘉庆以前尚不存在较为严重的粮食短缺以及红薯对土质要求比玉米高，其实最主要的原因是红薯的品质不如玉米。

Introduced into China in Ming Dynasty, corns and sweet potatoes were brought into Guangxi which was governed by both Tusi and authorized officials designated by the Central Government during Qing Dynasty. However, these two plants experienced big difference in the way and result of spreading in Guangxi.. corns enjoyed a fast spread and a wide planting area and became the major food crops in mountainous areas, while sweet potatoes spread at a relatively low speed and had a small planting area. As for the reasons, some hold that no severe food shortage had occurred before the period Emperor Jiaqing （1796- 1820）, and additionally the soil quality required by sweet potatos is higher than that for corns. Actually the main reason is that the quality of sweet potatos was inferior to that of corns.
