Sweet potato, potato, cassava, why is only sweet potato "ostracized" by the poor?

There are many kinds of truth in the world, but people often only choose the one that is beneficial to them. No matter how high-sounding the reason is, it must contain personal interests. This is human nature and cannot be avoided. The same is true for planting crops. People often choose to plant crops that bring the highest benefits to themselves. Most of the poor people in the world are engaged in planting, but there are also preferences for planting crops. What we are going to talk about today is why are the "three brothers" sweet potato, potato and cassava, and why are sweet potatoes "ostracized" by the poor all over the world?

The three major potato brothers in the world

On the earth, there are three types of potatoes. They are the three brothers: sweet potato, potato and cassava. Although they are all potatoes, they have their own characteristics. Different growth habits, different growth requirements

But the main thing is that they are both full of starch and are herbal plants, and they are also popular foods, and they are all imported from abroad. Crops were introduced into our country, but why do the poor around the world prefer cassava and potatoes and rarely plant sweet potatoes?

Sweet potatoes are commonly known as sweet potatoes, sweet potatoes, etc. Sweet potatoes were first planted in central America, that is, Mexico and Colombia. There are different opinions on how sweet potatoes entered my country, but most people believe that they were brought back by Chen Zhenlong and his son Chen Jinglun, a Chinese businessman in the Philippines during the Ming Dynasty.

But there is no clear evidence, it can only be said to be everyone’s guess. There is a reason why sweet potatoes are loved by Chinese people. Our country has sufficient light, fertile soil, a lot of precipitation, and the temperature is suitable for the growth of sweet potatoes. Therefore, in There are already more poor people growing sweet potatoes in our country than in other countries, but they are still not as large as the amount of potatoes and cassava grown.

Cassava is known as the "King of Starch" because of its high starch content. The content is not comparable to that of ordinary foods. Cassava is mostly grown in areas with poor soils such as Africa, America and Asia. After being introduced to my country, it is mostly planted in Guangxi, Guangdong and other places. The economic benefits of cassava are very good, and the yield of cassava is high. , and its uses are diverse, it can be used as feed for poultry, it can also be processed and used as cassava flour to make food, and it can also be used to make ethanol and other industrial raw materials.

When it comes to potatoes, most people's eyes light up. What are potatoes? Potatoes are the potato chips we like to eat. Potatoes are also called potatoes in some areas. It can be seen that potatoes are not a native crop in our country. , it was introduced to my country from Europe. Potatoes are loved by most people.

Potatoes can be fried, steamed, boiled, fried and stir-fried, and can meet the most important requirements of foodies. ?Delicious, potatoes are an essential dish on our table. The history of artificial cultivation of potatoes is also very long, and can even be traced back to 8000 to 5000 BC. It can be seen that potatoes have played an important role in human production and life. What a great effect.

Potatoes like cool places with plenty of light and rainfall. Therefore, in our country, potatoes are mostly planted in places with fertile soil and deep soil in the north. The poor people who grow potatoes see this. The value it generates is like a prince crossing the river, who started planting potatoes because the sales of potatoes are very good and the yield is also high, which is loved by everyone.

The crop adapts to the environment

People. As we all know, wheat is grown in the north of my country and rice is grown in the south. Crops have their own growing conditions, so when choosing crops, the first choice is to adapt to the local climate. Only by adapting to the local climate can crops grow, bloom and bear fruit.

Sweet potatoes have high requirements for growth conditions. They like areas with warm climates and have very strict requirements for light. They also have high requirements for temperature. They will stop growing at low temperatures and Sweet potatoes have different requirements for temperature at different stages of growth. Under these conditions, many places that want to plant sweet potatoes are deterred. Apart from these conditions, the cultivation of sweet potatoes also has high requirements for soil and requires a variety of of chemical fertilizers.

Most of the poor in the world are engaged in planting. The cost of planting sweet potatoes is very high, so in areas where the environment is not suitable for sweet potatoes or where poor people cannot provide enough fertilizer, the poor will give up planting. Instead of sweet potatoes, choose to grow cassava, potatoes or other crops.

Harvest and income determine whether planting one grain of millet in spring will yield ten thousand grains in autumn? Another big requirement for planting crops is harvest. Harvest determines many things. Harvest is also the yield. In cassava, Among the three brothers of potato and sweet potato, the yield of cassava is also significantly higher than that of potato and sweet potato.

Therefore, the planting conditions of cassava are obviously much lower than those of sweet potatoes and potatoes. It is suitable for planting in many places with poor environment and where water and fertilizer cannot keep up. Moreover, the labor cost of cassava planting is lower. The cost of artificially raising sweet potato seedlings is high, the planting history is short, and the technology is immature. In addition, pest control in the later period increases the cost of planting. Therefore, in the eyes of most poor people engaged in planting, growing cassava is more profitable and more efficient.

Practical value and edible value

If there is any reason for growing the same crop, it is the practical value and edible value. If we talk about practical value and economic value, the first choice is cassava.

The sales market of cassava is very broad. First, cassava can be used to extract cassava flour for use in some desserts and the like. Second, cassava can be processed into ethanol and become a fuel for automobiles. At the same time, Cassava can also be used as feed and processed into other industrial supplies. This value of cassava is not found in sweet potatoes and potatoes. Therefore, in terms of practical value, poor farmers around the world will choose to grow cassava.

Edible value. When it comes to edible value, potatoes are far ahead of sweet potatoes and cassava. Sweet potatoes taste sweet and can be used to cook porridge and other desserts, but there are not many ways to cook sweet potatoes. Sweet potatoes are rich in starch and are very filling. However, people who work for a long time prefer salty and oily meals, so they will have enough strength to work.

Moreover, most Chinese people’s tastes are spicy or sour, and few people in some areas have sweet tastes. Therefore, the edible value of sweet potatoes is not very great for poor farmers. Most poor farmers have Choose to sell large quantities of sweet potatoes after they are ripe.

Potatoes are our potatoes, and they are also a kind of food that most people like. Potatoes are tasteless and can satisfy our various ways of eating food. It is a home-cooked dish for the whole family, and compared to other vegetables, potatoes can be stored for a long time, have high yields, and have a good feeling of satiety. Most poor people live in remote places with inconvenient transportation, and the price of vegetables rises in winter, and potatoes can be eaten across seasons. Storage can also meet the needs of poor people for vegetables in winter. Therefore, in terms of food value, potatoes are higher than sweet potatoes and cassava.

Potatoes, sweet potatoes and cassava, there is a lot to consider when growing these three crops. Therefore, choose the best, comprehensively compare from all aspects, and choose the ones that can bring benefits. Whether it is economic value, food value, or practical value, sweet potatoes are lower than the other two brothers. Therefore, this is why potatoes are so popular. The reason why poor people around the world are "ostracized".
