China can earn 30 billion yuan a year by following suit, and the coming of autumn every year also means that a bumper harvest will be ushered in. But for the farmer's uncle, what followed was half joy and half sorrow. I am glad that the harvest is finally coming, and I am sad that the garbage left over from the crops is difficult to dispose of. For example, corn straw, although it has been said that China has burned straw for thousands of years, but the pollution caused by burning straw is really too great. Polluted environment, polluted air, China has clearly stipulated that straw burning is not allowed, but the annual open burning phenomenon is still repeatedly prohibited, which to a large extent caused environmental pollution.
For this difficult problem, the Americans have made a different move, not only did they not burn corn stalks, but they favored a large number of ** corn stalks. It is said that if our country follows suit, it can earn 30 billion a year, why would the Americans ** straw?
The United States is a big corn planter, and corn cultivation is only a strategic crop for the United States. According to relevant data, in 2020, the area of corn planted in the United States was 92 million acres, **3% from the previous year, and the yield increased by 2.31 million mu from the previous year. Compared to 2019, 28 U.S. states have increased or remained unchanged in corn planting, with an estimated corn harvest of 84 million acres, an increase of 3% year-over-year.
In addition, the U.S. government has heavily subsidized corn growers and encouraged farmers to strip corn from planting so that corn yields can be higher. Therefore, the degree of corn planting in the United States is much higher than that of other crops, so it shows the importance of corn planting. So why do Americans love corn so much?Is it because of the taste?The answer, of course, is not.
As for the relevant data, the annual output of corn in the United States is 300 million tons, but in 2020, the consumption of corn in the United States is only more than 5,000 tons, not to mention three meals a day. So, what exactly are Americans growing so much corn for?Americans may not guess that a large part of the reason Americans grow corn in large quantities is to get corn stalks.
Start planning for my 2024
In my country, every year because of the problem of straw burning, it will rush to the hot search. However, it is such a corn stalk that is not popular in our country that went to the United States but turned waste into treasure, why is this?It turns out that corn stover can be turned into biofuel ethanol through a series of processes, and each ton of corn stover can produce 500 liters of ethanol, which can provide 25% of biofuel oil for the United States every year.
So that's why Americans are so fond of corn stalks. I believe many people know that with the development of society, energy has also become the focus of competition among countries, oil, natural gas and other traditional energy is not renewable energy, and the new energy with corn straw as raw material is not only renewable energy, but also will not pollute the environment, in addition to being raw materials, but also made into plastic products, ordinary plastics are difficult to downgrade, and will pollute the environment. The degradable nature of corn straw plastic generally only takes two years, and if it is decomposed, it will also pollute the environment.
Although China is also a big corn planter, the way to deal with corn straw is not optimistic, most of the straw is burned, which not only pollutes the environment, but also has the risk of causing fire. If China follows the example of the United States and processes corn stover into biofuels and plastic products, so that farmers can not only make more money on straw, but also manufacturers can process ethanol and plastics, which can be described as a win-win deal.
In addition to this, straw that cannot be processed can also be made into handicrafts. All in all, these ways of disposing of straw are much better than direct incineration, and they can also be converted into income.
It is estimated that if China can follow the example of the United States and make full use of corn stalks, the annual income can reach 30 billion yuan, which can feed the lives of many people.
