Let potatoes gradually become the staple food on the table.

What would happen to the world if there were no potatoes? If you trace back to the past life of potatoes, you will find that how many small potatoes have changed human life in the history of the world and solved the problem of food and clothing for many people. Now, it has become the fourth largest food crop in the world.

Potato has been planted in China for more than 400 years, covering an area of more than 80 million mu, and has been planted in all parts of the country, including east, west, north, south, east, south, south, east, south, east, west, north, south, east, south, east, south, south, east, south, east, south, south, middle, spring, summer, autumn and winter. Potato is rich in nutrition, which contains all seven kinds of nutrients, such as carbohydrate, protein, vitamin, dietary fiber and so on. It is one of the ideal foods for modern people. However, due to the influence of consumption habits and market demand, the overall growth rate of potato production and consumption is not fast, the production level is not high, and the consumption capacity is not strong. Although the output has increased in recent years due to the promotion of western-style fast food, due to the lack of staple food products in line with Chinese cooking culture, the lack of special potato varieties and processing technology suitable for Chinese staple food products, and the lack of social and environmental conditions to guide the consumption of potato staple food, potato has not yet developed into a staple food.

At present, the time is ripe to promote the staple grain of potato. In recent years, the society's understanding of the nutritional value of potatoes has been deepened. in line with the new needs of urban and rural residents to eat well and eat healthily, the market environment for promoting the main grain of potatoes has been formed. Moreover, potato is resistant to cold, drought and barren, and has wide adaptability. It can be planted in most areas from south to north and from high altitude to low altitude. It has a good effect of water-saving, land-saving, fertilizer-saving and medicine-saving, and can be used as the main substitute crop for agricultural structure adjustment. It meets the new requirements of sustainable development and structural adjustment of agriculture. Coupled with the successful research and development of potato staple food product formula and processing technology, variety breeding and supporting technology development, such as the completion of potato genome fine map in China in 2011, which provides theoretical support for potato molecular breeding, all these have laid a good foundation for potato staple food.

Today, with the continuous pursuit of dietary diversity and nutritional health, it is an important measure to actively promote the transformation of potatoes from non-staple food consumption to staple food consumption, and to develop and provide a series of fully nutritious potato products suitable for Chinese people's consumption habits of three meals a day. In the future, we should continuously increase the intensity of work and strengthen measures, and strive to significantly improve the planting area, the level of per unit yield, the total output and the consumption of staple food products after several years of unremitting efforts, so that potatoes will gradually become the staple food on the table of the common people.
