中国马铃薯产业发展与食物安全

 在人口增加、耕地面积减少、水资源缺乏以及水稻、小麦和玉米三大粮食作物种植面积下降等因素的影响下，中国食物安全存在着潜在的危机。马铃薯作为一种兼用型农作物，具有较高的水分利用率和较长的产业链，种植面积逐年增加。可利用冬闲田进一步扩大马铃薯种植面积，与三大粮食作物相比，其单产还有较大的增加潜力。马铃薯产业的不断发展，将对缓解中国食物安全压力起到重要作用。

Development of Potato Industry and Food Security in China

Under the pressures of population increase, arable land decrease, water shortage, planting area reduction of three major grain crops (rice, wheat and maize) in recent years, there is a potential crisis in food security in China. As an all-purpose crop with high water utilization efficiency and long industrial chain, the potato planting area has been increased year by year. Compared with the three major grain crops, potato planting area can be further increased by using the winter fallow fields and its yield can be further increased as well. With the development of potato industry, potato will play more and more important roles in alleviating the problem of food security in China.
