Why did China start its strategy to become a staple potato food?

China now has a large population, the pressure on food rations is increasing, the original staple grains rice and wheat have a certain risk of shortage, so we should make arrangements in advance, develop some crops that can resist the shortage of staple food, and add them to the staple food category, so as to improve social stability. And here, potatoes are chosen for their high energy, ease of production and safety. Personally, I think that's all.

As for whether there is a problem with the country's grain reserves, I think it's unlikely, after all, our current grain ** is counted in the world, if there is a problem, then the first thing should be that the grain becomes single (because at that time the country must first make up for the gap in staple food), but now there is no sign at all. In addition, I hacked India, India has the best arable land in the world, but most of the people do not have enough to eat, and the most frustrating thing is that India is still an international grain exporter, that is, the people who do not have enough to eat at home do not provide relief, but use their own grain to sell internationally. <>

When it comes to food safety, it is not food quality and safety, but genetically modified organisms. Potatoes are relatively good in this regard. Therefore, among the candidates for the development of spare crops, he has his advantages, so it makes sense for the country to promote him (not that GMO is unreliable, mainly because China has little advantage in GMO technology, and at this time we must make use of our strengths and avoid weaknesses, avoid GMO crops, and prevent being generalized by foreign countries).

The connotation of potato staple food is to use potatoes to process into staple food products such as steamed buns, noodles, and rice noodles suitable for the consumption habits of Chinese, so as to realize the current transformation of potatoes from non-staple food consumption to staple food consumption, from raw material products to industrialized series of manufactured products, and from subsistence consumption to nutrition and health consumption, as a supplement to China's three major staple foods, and gradually become the fourth largest staple food crop. <>

Until now, the Chinese population will break 1.5 billion (estimated to have exceeded it, the base is too large), although there are some great talents such as Academician Yuan Longping who have made breakthroughs in biotechnology, and now Mr. Yuan Lao has broken through the yield of rice by 1,000 kilograms, that is, broken through one ton, here is the link: Yuan Longping's super rice has a large area of more than 1,000 kilograms to set a world record (photo) Netease News Center, but these are still a little stretched. After all, rice belongs to grains, and you can't expect him to continue to break through, although theoretically he has the possibility of breaking 10,000 kilograms (sorry I'm not in the black money Mr. Xuesen), but now it is very unrealistic.

At the same time, China's red line of 1.8 billion mu is becoming more and more vivid, and China must ensure that the people eat well while ensuring that the people are well fed (many countries have far less abundant food baskets than China). Of course, many people say that the United States is also rich in vegetables and fruits, but the geographical environment and weather climate of the United States are second only to India, and there are advanced industries, which are similar to the level of China, which is natural), when the idle fields in European countries are used to grow flowers, China has planted a variety of non-major crops, such as onions, ginger and garlic. Then land is extremely precious, if we take into account the occupation of cultivated land involved in the future land reform, our cultivated land should be under the withering line, only a little.

You know, we only have seven percent arable land at best.

In this is where the potato has his natural advantage, that is, the yield is large. And the requirements for the planting environment are not high. I remember that when I visited a ginseng field in Korea, the old farmer (who should be the old village chief) told us that we could not grow crops within seven years after planting ginseng, and we could only raise them.

The comparison is soybean peanuts, these two crops are for land-raising, and my uncle showed me the peanut field, saying that those small rhizobia are very effective for land-raising. As for potatoes, although he can't raise the land, he doesn't damage the land, and the yield is very large (I think the reason for the large yield is because potatoes are a very dense thing in crops). <

The yield of sweet potatoes is not as high as that of potatoes, the planting and storage are complex, the nutritional value is not as good as potatoes, and the nutritional value is not as large, which are all reasons why sweet potatoes cannot become a staple food.

Sweet potatoes and potatoes are both potato ingredients, but potatoes are recognized as a staple food, and people also advocate the staple food of potatoes, but people do not recommend making sweet potatoes a staple food. Because sweet potatoes have many shortcomings compared to potatoes, their yield is much worse than that of potatoes. The yield of potatoes per mu is between 2 kg and 4 kg, while the yield of sweet potatoes is between 2000 and 3 kg per mu.

But potatoes can be grown multiple times a year, while sweet potatoes can only be grown once a year. In terms of annual yield, potatoes are much higher than sweet potatoes.

Considering the planting area and yield of potatoes from the yield factor, it is easier to solve the problem of rations in our country, so it is easier to become a staple food, while sweet potatoes cannot meet these conditions, so it is difficult to become a staple food. Potatoes are a plant that is easy to grow and store, and the planting method of sweet potatoes is very different from that of potatoes. When planting, it is often limited by temperature and environment, so it cannot be popularized in a large area, and the storage of sweet potatoes after harvest is also a big problem, and if it is not stored, it often rots and deteriorates.

The reason why sweet potatoes are not recommended as a staple food is also because the nutritional value of sweet potatoes is not as high as that of potatoes. The main beam of food should not only consider its satiety, but also its nutrition and health. Potato is a healthy food with high nutritional value and good for human health, and sweet potato is slightly worse than potato, and there are many people who are not suitable for eating sweet potato, especially the three high people and gastrointestinal insufficiency, as well as people with diabetes will have adverse reactions after eating sweet potato, and they will not affect their health when they eat potatoes.

It is not recommended that sweet potatoes become a staple food, but also because people eat sweet potatoes as a staple food, which will affect gastrointestinal function, easy to have flatulence, and will also have a variety of uncomfortable symptoms such as heartburn and spitting sour water, which will affect the normal digestive function of human beings. In addition to these reasons, potatoes are eaten in a variety of ways, can be cooked with a variety of ingredients, and can be used to meet people's daily dietary needs, which is why they are regarded as a staple food by people, while sweet potatoes have no advantage in this regard, so sweet potatoes have not become a staple food in people's lives.

Because there is too much starch in sweet potatoes, eating too much may lead to excessive secretion of stomach acid, and sweet potatoes are not easy to store; Sweet potatoes are very rich in calcium and vitamins that can promote the growth of our bones, potatoes contain a lot of starch, and some proteins can supplement our body with sugar, and can also improve the body's energy.

Because sweet potatoes cannot be used as a staple food in terms of storage or nutrition, the difference lies in some of their nutritional value.

The main reason is that the nutrients in sweet potatoes are insufficient, which can not provide sufficient energy for the human body, and in addition, the taste of sweet potatoes is too sweet and not suitable for the general public.

Sweet potatoes have a very high starch content and a lot of fibrous substances, so too much intake will easily cause bloating and indigestion. Although potatoes are high in starch, they do not cause bloating or indigestion, so potatoes can become a staple food.

Because eating too many sweet potatoes is not good for the stomach, and there will be sour water in the stomach after eating, if you eat too many sweet potatoes, it will make people get a series of stomach problems.

Because sweet potatoes have high temperature requirements and are difficult to grow in large areas, they cannot be used as staple foods.

Sweet potatoes are not as adaptable as potatoes, and the consumption of sweet potatoes has limitations. Eating too many sweet potatoes will cause heartburn.

Potato producers in order of output: China, India, Russia, Ukraine and the United States, the current total annual potato planting in China has exceeded 100 million tons, and the annual output of the remaining four countries is also more than 20 million tons, and sweet potato planting is mainly concentrated in Asia, and the total output is less than 200 million tons, from this point of view alone, potato globalization planting is a trend, and sweet potatoes in a short period of time can not achieve a counterattack, the failure of the main food, looking at the world, losing to potatoes is also an inevitability.

Is there a more cost-effective crop in the world than sweet potatoes?

But sweet potatoes are already a staple food, and he can't eat them as vegetables, potatoes can.

The future of our country's food.

Consumer demand is still showing a rigid growth trend, and the increase in grain demand will be more than 100 billion catties by 2020. However, due to the constraints of cultivated land and water resources and the influence of planting efficiency, the cost of increasing the output of wheat, rice and other food ration varieties has increased, the space has become smaller, and the difficulty has increased, and it is necessary to open up new ways to increase production. Potato is cold-tolerant, drought-tolerant, barren and thin-tolerant, and has wide adaptability, especially in the development and utilization of winter fallow fields in southern China, and has great potential for expanding potato planting.

In addition, China's potato yield is relatively low, and there is greater potential to rely on science and technology to increase yields.

Especially from the perspective of water conservation, promoting the staple food of potatoes is conducive to alleviating the pressure on resources and the environment and achieving sustainable agricultural development. Potatoes require less water to grow, with a minimum transpiration coefficient (water requirement) of only 350, compared to 450 for wheat and 500 for rice. In the arid and semi-arid areas of northwest China, where annual precipitation is about 350 mm, cereal crops are difficult to grow and develop, while potatoes can not only grow normally, but also reduce soil erosion.

Last year, the Ministry of Agriculture conducted an experiment in Hengshui, Hebei Province, and found that in the overexploited groundwater area of North China with an annual precipitation of 500 mm, the yield per mu of potatoes still reached tons under the condition of complete rain-fed. Farmers plant potatoes to save water, fertilizer, medicine, and energy.

Potatoes as the staple food is the trend of the times, look at the United States and Russia abroad, the fighting nation is so strong, there is the credit of potatoes, in the northwest of our country, potatoes are also eaten very much, the whole is baked, shaved and sprinkled with pepper powder to eat directly.

A strategy for processing potatoes into steamed buns, noodles, and rice noodles as a staple food. The strategy of turning potatoes into staple foods refers to processing potatoes into staple foods such as steamed bread, noodles and rice noodles, and potatoes will become another staple food in addition to rice, wheat and corn. According to the Ministry of Agriculture, China will launch the strategy of turning potatoes into staple foods, promote the processing of potatoes into steamed bread, noodles, rice noodles and other staple foods, and potatoes will become another staple food in addition to rice, wheat and corn.

More than 50 percent of potatoes are expected to be consumed as a staple food in 2020.

Potatoes are called"Perfect"The nutritional products are rich in dietary fiber and low in fat, which is conducive to controlling weight growth and preventing high blood pressure, high cholesterol and diabetes. The per capita annual consumption in European countries has stabilized at 50-60 kg, and in Russia it has reached more than 170 kg. For example, the per capita annual consumption of European countries has stabilized at 50 60 kilograms, and the per capita consumption of Russia has reached more than 170 kilograms.

At present, only a few regions in China regard potatoes as a staple food, and more people eat potatoes as vegetables. In the future, potatoes will change from non-staple food consumption to staple food consumption, "potato staple food is actually processing potatoes into staple food products such as bread, steamed buns, noodles and other staple foods that adapt to Chinese consumption habits, and change from non-staple food consumption to staple food consumption."

By 2020, China's grain demand will increase by more than 100 billion catties, but due to the constraints of cultivated land resources and the impact of planting efficiency, the space for wheat, rice and other staple food varieties to continue to increase production has become smaller and more difficult. The potato is cold-tolerant, drought-resistant, barren-tolerant, widely adaptable, and easier to plant, and belongs to the "four provinces" crops of "saving water, fertilizer, medicine, and energy". China's potato production supporting cultivation technology is becoming more and more mature, integrating key technologies such as double ridge, film mulching, drip irrigation, water and fertilizer integration with agricultural machinery as the carrier, and successfully developed staple food products such as steamed bread, noodles, rice noodles and snack foods such as bread, which account for more than 35% of the total potato flour.

When it comes to the goal of the potato staple food strategy, Yu Xinrong, vice minister of the Ministry of Agriculture of China, said that it is expected that more than 50% of potatoes will be consumed as staple food in 2020, and the country should strive to make significant progress in the planting area, yield level, total output, and the proportion of staple food products in the total consumption of potatoes, and potato staple food products have become one of the choices of the people's three meals a day.

In China, especially in the vast western region, the climate and water and soil conditions are very suitable for growing potatoes, and the yield and economic value far exceed the traditional wheat, corn and other grain crops, and their yield increase potential is also greater than that of corn, wheat and rice, which are subject to climate, water and fertilizer conditions, and potatoes are much less restricted by these factors. Therefore, potatoes have great potential in terms of economic value and strategic value for food security. It is precisely for this reason that promoting the strategy of turning potatoes into "staple foods," actively expanding potatoes and their processed products, and expanding the industrial chain of deep processing of potatoes are of very positive significance to the underdeveloped areas of the western region in terms of increasing agricultural output value, adjusting the agricultural planting structure, and increasing peasant incomes.

Even in the process of implementing targeted poverty alleviation in rural areas, the strategy of "staple food" of potatoes also has a strong role in promoting. It can be said that the "staple food" of potatoes is a win-win strategy that is beneficial to national health and economic development.

Of course, whether from the perspective of national strategy or nutritional advantages, promoting the "staple food" of potatoes requires effective "tactical" means to make people increase their consumption, which is the key to the success or failure of the strategy of "staple food" of potatoes. Now, after scientific and technological research, the potatoes that were originally eaten in a single way have been made into biscuits, steamed buns, noodles, peach cakes, moon cake residues and wild plums, and the use of potatoes has been greatly expanded, which is a positive market exploration for promoting the "staple food" of potatoes. However, it may be more important to actively promote the deep processing of potatoes than to directly transform the way potatoes are eaten.

At present, the development of society has led to the increasing daily consumption of processed foods, such as corn, a staple food, is now more used as feed, transformed into a variety of meat and served to the public's table. Therefore, through deep processing, potatoes are decomposed into starch and protein, and after appropriate improvement, they become more important raw materials in various processed foods, which may be a more effective direction for the implementation of the "staple food" strategy of potatoes in the future.
