i have a small world

Zhou Wenqing is 64 years old this year. He is now a professor at Anxi Agricultural University. Zhou Wenqing is that kind of real professor, not those so-called "beastmen" on TV. He is a rice professor at Anxi Agricultural University. The leader of the research is here, and he has a strong skill in rice research.

Of course, as a guy who studies rice all the year round, Zhou Wenqing often goes to the fields in person. He even planted a few acres of rice in the research base of Anxi Agricultural University. The food of Zhou Wenqing's family is taken from these experimental fields. Zhou Wenqing wanted to commit suicide, but to test whether the food in the experimental field would have any bad effects on the human body after eating it.

Zhou Wenqing has always believed in one thing, if you want the people to accept what you have researched, you have to test it yourself first, otherwise it would be very irresponsible for you to use it for the people without testing it yourself. .

Therefore, every time a new type of rice is introduced, Zhou Wenqing and some of his students will first taste the taste of the food grown from these types of rice, whether there is any discomfort after eating, etc., in order to The most important thing is to make the food on the table of ordinary people absolutely safe and delicious.

Zhou Wenqing has gradually become a figure not to be underestimated in the field of rice research in China by virtue of his persistence and serious and responsible work attitude. Of course, after decades of personally cultivating rice in the fields, Zhou Wenqing now looks like An old farmer was more than a university professor, and Zhou Wenqing didn't have a scholarly air at all.

Zhou Wenqing didn't care much about the emergence of martial arts secrets before. He always thought that martial arts practice was a waste of time. If you have this time for martial arts practice, you might as well spend it on researching rice. These things are real. event.

China is a populous country, but China's current arable land area is only 18 billion mu, a decrease of 460.2 million mu compared with the previous year. The per capita arable land area in the country is 1.39 mu, approaching the red line of 18 billion mu.

However, although China has more than 18 billion mu of arable land, the grain yield per mu of arable land varies from north to south.

In the south of North China, cultivated land is cropped twice a year, and winter wheat yields 800 jin per mu in one season, which can feed one person.One season of corn can also produce 800 catties per mu, which can also feed one person.The average person has more than 2 catties of grain a day, which should be sufficient for food and clothing.The cultivated land in the south of North China is cropped twice a year, and one mu can feed two people.

In the Northeast, cultivated land is harvested once a year, and the yield of wheat or corn per mu is close to 800 jin, which can feed one person; in the Northwest, cultivated land is harvested three times in two years, or once a year.The yield per mu is slightly lower, and each mu can basically support one person; in Lingnan, where there are three crops a year, each mu can basically support three people, which may be slightly less; in Jianghuai, paddy fields, one mu can support more than two people.

There is no precise statistics for these data, they are all estimated numbers, but the actual situation in China is not much different from this. It can basically be considered that one mu of cultivated land in China can feed two people on average.Maybe a little less than two people, but not much.

If there are 2 people per mu, China's 18 billion mu of arable land is all planted with food crops, which can feed 36 billion people.These 36 billion people can fully satisfy their food and clothing, but they don't eat much meat.Now China's population is only 13 billion people, doubled to 26 billion people, we can still support them.

But don’t think that we will have no worries, because our arable land not only grows food, but also needs to grow some weak white noodles, such as tobacco leaves, which require tens of millions of acres of arable land. There are many tobacco leaves in North China. of arable land.If 00 million mu of arable land is needed to grow tobacco leaves, according to two crops a year, the rations of 5000 million people can be reduced.

We also need to wear clothes, so we need to grow cotton.This also requires tens of millions of acres of arable land. Cotton is better, and wheat can be interplanted, and the food rations for about 5000 million people will be reduced.Therefore, planting cotton and tobacco leaves reduces the food rations of 1 million people.

We need to eat vegetables, and probably need to reduce the rations of 1 million people.We need oil crops, and probably need to reduce the rations of 2 million people.There is also a need for crops such as sugar crops, melons and fruits, and peppers, and it is necessary to reduce the rations of 2 million people.

A lot of arable land suffers from natural disasters every year. Based on the calculation of hundreds of millions of mu of arable land affected by disasters every year, it is estimated that the food rations of 2 million people can be reduced.The above factors have reduced the food rations of 8 million people in total.

To sum up, probably China can feed (24 million people now, if the possibility of overestimation is taken into account, maybe China can feed 30 billion people. If it is underestimated, China can now feed more than [-] billion people.

But this is only a handy way of estimating land to support population.These estimates of the number of people that China's arable land can support, and the standard of living are only at the level of food and clothing, not at the level of a well-off society.According to the well-off level, it would not be able to feed so many people.

Because small people eat a lot of meat, corn and other grains are fed to livestock, and everyone eats these corns indirectly through eating meat.A well-off level also means a lot of consumption in other areas.

For example, more fruits, condiments, etc. are consumed, which will also take up more arable land.People may keep more pets, and these pets will also consume the rations of hundreds of millions of people.People will drink more alcohol and consume some food.People would need more clothes, which would require more cotton, which would also reduce food production.

And the most important thing is that the process of urbanization is greatly accelerated today, and many cities are developing faster and faster, so the scale of the city is also getting bigger and bigger, and the bigger the city, the bigger the surrounding suburbs it annexes. The greater the extent to which a city annexes surrounding suburbs, the more vast amounts of arable land disappear.

You must know that the cultivated land around the city has always been the best cultivated land. As these cultivated lands disappear year by year, the area of ​​cultivated land in China is also rapidly decreasing. Coupled with the current implementation of the policy of returning farmland to forests, the area of ​​China’s cultivated land It is already getting less and less, and the breaking of the 18 billion mu cordon is just around the corner.

Therefore, in order to feed China's 13 billion population, in addition to expanding China's territory, it is necessary to accelerate research on high-yield grains. Academician Yuan's hybrid rice saved the Chinese people at that time, and now it is their turn to develop more high-yield grains. Rice varieties too.

However, it is not easy to study new high-yield rice varieties, which require a lot of time and materials, especially new wild rice varieties. Academician Yuan's hybrid rice was developed on the basis of wild rice varieties, but As the environment is getting worse and worse, a large number of wild rice species have disappeared in the river of history. It is really difficult to find a brand new wild rice species now.

However, Zhou Wenqing actually obtained several new wild rice seeds from his students in May, which made Zhou Wenqing very excited. Of course, Zhou Wenqing soon learned the origin of these wild rice seeds. The rice seeds that his students found when they went to play in the Wulin Secret Realm during May Day.

This matter made Zhou Wenqing knock his head hard. Due to the serious environmental pollution on the earth, it is difficult to find new wild rice seeds, but new rice seeds can be found in the beautiful martial arts environment. The chances were definitely high, so Zhou Wenqing immediately took his students and assistants and set off towards the martial arts secret environment, where there was a brand new wild rice seed that they had always dreamed of.

As soon as he entered the Wulin Secret Realm, Zhou Wenqing felt that the Wulin Secret Realm was indeed a fairyland on earth. Not to mention the indigo sky and the fresh air, it was so charming that people would linger on it just by looking at it. The soil on that land is so fertile.

If it is said that the fertility of cultivated land on the earth reaches 100 points (percentage scale), the fertility of the land in this martial arts secret environment is absolutely [-] points. As long as such good land is planted with grain, a good harvest is a sure thing.

Seeing such fertile soil and fresh air, Zhou Wenqing was very excited about this research operation, and he felt that he would definitely gain a lot this time.

And the result was just as Zhou Wenqing expected, this time their harvest was really great. Zhou Wenqing and the others not only found more than 30 new wild rice species in the martial arts secret environment, but they also discovered something even more surprising.

The yield per mu of rice farmers in Yushi District actually reached nearly [-] kilograms, which stunned Zhou Wenqing and his team. It is absolutely unexpected that there will be such a large yield per mu.

If there is such a production of rice on the earth, then there will be no food crisis in China, and there will be no need to import a large amount of food from those poor countries.

After Zhou Wenqing and the others knew the rice output of this farm family, they asked him about the origin of his rice seeds. To Zhou Wenqing's surprise, the rice seeds grown by this farm family were actually developed by them. No. Rice (made up), this situation made Zhou Wenqing and the others really unbelievable.

Zhou Wenqing and the others immediately began to test the rice seeds. Sure enough, the situation was exactly the same as what the old farmer said. This made Zhou Wenqing feel incredible. How could the rice seeds have such a big change?
Zhou Wenqing and his party stayed here because of this, and if they didn't study the abnormality inside, Zhou Wenqing was not going to leave. As long as he developed the reason for such a mutation, China would no longer have to worry about food in the future.

For professors like Zhou Wenqing, it is their biggest dream to serve the country. In order to realize this dream, it is worth spending a few years in the secret world of martial arts. Compared with making China stop worrying about food in the future, suffering a little bit is really nothing. Nothing.

After Zhou Wenqing and the others stayed in the martial arts secret environment, they used their solid knowledge to solve a large number of rice planting problems for a large number of farmers, especially in the prevention and control of some diseases and insect pests. They are loved and loved.

In order to better develop rice seeds, Zhou Wenqing and the others applied for [-] acres of land as their research base. When Zhou Wenqing and the others started researching rice seeds in a hurry, he didn't know that a black hand had reached out to Without Zhou Wenqing and the others, Zhou Wenqing was in danger.

The dwarf country and the monster country have always been big rice exporters. To be honest, the rice industry accounts for about 40.00% of the national income of the dwarf country and the monster country. Pillar industries, and these two countries rank first and second in the world's rice exporting countries. It can be seen that the importance of the rice industry to these two countries is unparalleled.

The quality of the rice in the Dwarf Country and the Human Monster Country is quite good. Not only are the grains full, the taste is very good, and the aroma of the rice grains is very sweet.What is even more satisfying is that the two countries pay close attention to quality control when planting rice. The fertilizers used in the rice fields are all organic fertilizers, and the pesticides used are also biological pesticides.

Therefore, the harmful substances contained in the rice produced by these two countries are equivalent to zero, and it can be said that it is a real green rice. Therefore, it is certain that it will be very popular in the modern era when food safety is emphasized.Coupled with the low breakage rate of the rice in the Dwarf Country and the Human Monster Country, the rice of the two countries is invincible in the international market.

It can be said that the government of the dwarf country and the demon country have made a lot of money in the rice market. They have already regarded the national rice market as a cash machine for their governments, so as long as any country wants to get money from the rice market Even if you take a bite of meat, you will be attacked by the dwarf kingdom and the monster kingdom.

However, the two countries are accustomed to price wars. Compared with the production cost of rice, the low labor costs of the two countries are enough to make them invincible in the price war. In addition, the two countries are struggling in the national grain market. Annihilation, so in the past few decades, no country can shake the status of the little dwarf country and the monster country as the world's number one rice exporter and the second rice exporter.

Originally, the two countries thought that such things would continue forever, but something unexpected happened to them this year. A batch of grain suddenly appeared on the international market, but the amount of these grains was very small, and the price was so high that it was shocking. daunting.

After the little dwarf country and the human monster country government ax knew about this situation, they didn't care at all, and they still secretly ridiculed whether the food seller was crazy about money, and he actually sold more rice than the best quality rice in their country. Dozens of times higher price, this is not whimsical, what is it? !

They believed that the rice would never be sold in the end, but something happened that made them dumbfounded. The rice had just been put on the trading platform, and the rice was sold out in just a few seconds. On the two sides of the country, Monk Zhang Er was confused and confused.

But this incident really hit the little dwarf country and the monster country. At first, they thought that the people who bought the rice were just hired by the seller who placed the order, and they just wanted to raise the price of their own rice. But it is often done, but the feedback shows that the people who bought the rice were some big shots in the United States. This fact made the little dwarf country and the monster country frown. They knew that this time they were in big trouble. (To be continued.)
