Ming and Qing dynasties, with the rapid growth of the population, a growing problem of food shortages. In this social context, the American high-yielding grain corn, sweet potato, potato into China one after another in the middle of the Ming dynasty, played an important role in the solution of the food problem in China. Center, explore the three crops States Period from Ming Ye Zhimin them in our introduction, dissemination and utilization, and focus on the tremendous impact they produce. Corn, sweet potato, potato, three pathways of the food crops of the Americas has always been different opinions, is difficult to determine. In this paper, based on the local history of the Ming and Qing Dynasties and the agricultural history of ancient records, analyzed and summarized route incoming course, subregional and their spread in China's, summed up the basic features of its spread distribution. Details of our working people, the multiple uses of these crops, reveals the importance of the lives of our people and agricultural production. Three crops of incoming and promotion of our many, one played a certain role in promoting agricultural production and socio-economic development, in this article from arable land to expand, the improvement of grain yield per mu and the total grain output increased three examine their impact on China's grain production, and food crops structural changes; examine their impact on the socio-economic development in China and from the food commercialization and development of mountain areas, the development of economic crops and handicrafts and commercial aspects. Played an important role in the diet of the people living in our country. Third, the impact of population growth, from the study of the Qing Dynasty, the population growth, combined with the propagation characteristics of the food crops of the Americas, to analyze its internal relations. Fourth, the impact on the ecological environment, large amounts of data references Chronicles cultivated species of corn caused by environmental degradation lead to reduced agricultural productivity. In short, the Ming and Qing Dynasties the Americas food crops, corn, sweet potato, potato incoming, the spread had a huge impact on China. Innovation of this paper is investigated from the diet angle analysis of the impact of three exotic crops, food crops widely Americas hundreds of years, first became the staple food of the mountain people, but also to other regions of China's traditional staple structure changed corn and sweet potato largely replaced by a variety of traditional low-yielding grains planting become the main force of the grains in traditional agricultural areas has always been the main crops of rice and wheat Shuji cheaper diet lives of poor farmers choice. Corn sweet potato became the staple food of the poor, and reflects the deepening of the crisis in agriculture, but also to some extent to promote the commercial grain trade. Through the analysis of this transition process, you can understand our working people diet system changes brought by the Inter-American food crops, these crops further people's lives today.
