Yuan Longping s team successfully planted seawater rice in the desert with high yields, do you think

Speaking of Yuan Longping, the old man, everyone will certainly not be unfamiliar, for the development of China is definitely a historical level of great man, we were not even able to eat enough in the early days because of the famine, but now the food is completely fine, this is Yuan Longping's pay, and people are also puzzled that Yuan Longping's team planted seawater rice in the desert with high yieldDo you consider this a scientific advancement? I think so, after all, it has to overcome a lot of hardship conditions, and it also makes a great contribution to society.

First of all, in the early days, China just began to develop, many science and technology are very backward, compared with other developed countries is really a big gap, but now the development, the gap with developed countries has narrowed a lot, this can really be said to be a miracle, this is the success of countless Chinese efforts, the most important thing in the early days is to solve the problem of rations, at that time really many places can not even eat enough, the direct problem is that the yield of rice is too small, and there are famines, etc., And Yuan Longping began his own research at that time.

Generation after generation of successful rice appeared, followed by super rice, which directly solved China's food problem, and even can be exported to other countries, and now it is to the desert to plant seawater rice with high yield, you must know that there are many desert areas in the world, and basically there is no use, after all, if you want to use, no matter when the construction or planting is too difficult, so this time in the desert planting seawater rice high yield success I think should be a scientific research progress.

Now it is not said that there is a breakthrough in scientific and technological progress, it can be regarded as the progress of scientific research, and it can be said that there is a huge contribution to society, this kind of behavior can directly make the desert have a huge use in the world, and it is a great contribution to the whole country and even the world, after all, there are still many desert areas in the world, many of which are difficult to use, but now there is a possibility.

I think it's a scientific advance. Yuan Longping's experiment in the desert will provide a reliable guarantee for China's grain and make great contributions to national scientific research.

Count progress. Because it is of great practical significance to grow seawater rice in the desert to achieve high yields, after all, there are many deserts that have not been developed.

It is a kind of scientific progress. Because it has broken through the restrictions of rice cultivation in high-salinity soil, it has been possible to grow rice in deserts.

As the saying goes, "food is the sky", and food is the material basis for our survival. If there was no food, there would be no human beings in this world. A few decades ago, China was very poor and its grain production was very low, so many people had no way to solve the problem of food and clothing.

Under such circumstances, Yuan Longping appeared, and he spent a lot of time developing hybrid rice, which increased China's grain output and solved the problem of people's food and clothing. In recent years, Mr. Yuan Longping has made a major breakthrough in rice, that is, he invented high-yield seawater rice, and the invention of seawater rice is of great significance to China's grain production. So what is the significance of Mr. Yuan Longping's invention of high-yield seawater rice?

Here's what I think:

1. What is seawater rice?

Seawater rice is not a rice planted in seawater, but a rice that can grow normally under the irrigation of saline-alkali land and seawater. Due to some problems in the world, there will be a lot of saline-alkali land, which cannot grow crops, while seawater rice can be planted on such plots, and can reach a certain yield.

2. Seawater rice can make efficient use of land.

Crops cannot be grown on saline land, nor can crops be grown on arable land close to the sea, so there will be a lot of vacant land, resulting in waste. After the invention of seawater rice, these saline-alkali lands and lands that are susceptible to seawater erosion can also be used to grow crops, which can effectively reduce the waste of cultivated land and effectively use China's cultivated land resources.

3. Enhance China's international status.

Saline-alkali land is not only available in China, but also in other countries. After the invention of seawater rice, China will be able to exchange this patented technology with other countries and help other countries to effectively use the land, which will be conducive to enhancing China's international status.

The success of this technology has benefited not only our people, but also our country and the whole world. So Mr. Yuan Longping's invention can be imagined what significance and value it has.

The significance of seawater rice lies in the fact that these rice can be cultivated in saline-alkali land, especially in the coastal areas, and the invention of seawater rice can provide more food for our country and even the world, and reduce the number of people who cannot eat.

It can promote the growth of rice production, help to improve China's grain output, and promote the improvement of agricultural level.

Personally, I feel that it is of great significance, first of all, it can increase China's grain output to tens of billions of tons per year, and it can also save fresh water for irrigation, and it can also increase the world's grain output when it is widely popularized, especially in some poor and backward countries and regions.

The significance of the invention of high-yield seawater rice is that we can achieve complete self-sufficiency in grain without having to go out to buy it in the future, and we can even export grain to foreign countries to promote our economic development.

Mr. Yuan Longping's invention of high-yield seawater rice means that there has been a major breakthrough in the technology of growing food, and will provide food reserves for tens of thousands of people, so that people have abundant food rations.

Through the invention of seawater rice and hybrid rice, Mr. Yuan Longping has greatly increased China's grain output, which has played a great role in modern economic development and human civilization.

First, to alleviate the worldwide food shortage during the pandemic. Second, we can make fuller use of the vast ocean resources on the earth, make the impossible possible, and make great contributions.

This means that rice can be grown in saline soils as well as in seawater, which can greatly increase food production and solve the global food problem.

The technologies used in seawater rice include: gene sequencing technology, which screens out natural salt resistance, alkali resistance, and disease resistance genes; Conventional breeding, hybridization and molecular marker-assisted breeding techniques.

"Seawater rice" is the common name of saline-alkali tolerant rice, is a kind of rice varieties that can grow in saline-alkali land such as seaside tidal flats, not directly in seawater, but planted in the land through which seawater passes, and has the three characteristics of no need for fertilization, resistance to diseases and insects, and salt and alkali tolerance, so it can turn wasteland into fertile land.

When it comes to the desert, everyone's impression is that there is a high temperature and water shortage, and the wind and sand are raging, but now there is a unique scene of desert on one side, fields on the other, and rice all over the ground. Desert rice can be gradually expanded and eventually become an "artificial oasis".

As one of the three major staple foods in China, rice has a very large planting area in China, especially under the research and development of hybrid rice, the yield of rice has been continuously improving. China's scientific research experts saidIn fact, the soil that is most suitable for rice growth is actually the desert. After all, the environment has not been destroyed, and greener rice can be grown

For example, in the desert of Inner Mongolia and Xinjiang, the temperature difference between day and night here is more obvious, which is more conducive to the growth of rice. The high temperature during the day meets the needs of rice for heat preference, and the temperature at night is relatively low, which can better precipitate nutrients.

The soil has a lot of silicon, and the groundwater is melted by snow, which tastes sweet and clean, and the rice is producedThe content of trace elements is much higher than that of conventional rice. In addition, growing rice in the desert can also save a lot of water, and only 400m of water is needed to grow.

The team of Qingdao Seawater Rice R&D Center led by Yuan Longping, an academician of the Chinese Academy of Engineering, recently measured the yield of rice experimentally planted in the tropical desert of Dubai, with a maximum yield of more than 500 kilograms per mu. This is the world's first successful experimental rice cultivation in a tropical desertIt will add "China's contribution" to improving the food self-sufficiency capacity of desert areas, ensuring global food security and improving the ecological environment of desert areas

I think the technology of growing rice in the desert can be used to green the desert. But growing rice does not green the desert.

I don't think so, because rice is for food, it is harvested every year, and it cannot be used for greening.

I don't think it's very practical, so I can only say that it can be changed temporarily, and it still has no effect in the long run.

Grow rice in the desert! Definitely not! I bet. At most, he has developed drought-resistant rice, such as planting it in the soil. Rice cannot be grown in the desert. Because of the lack of water!

Yuan Lao first slowly increased production and brought up the delicious taste. I only eat two or three taels of rice a day, and I only eat fragrant rice, northeast rice or other old varieties of rice. In addition, don't make tomatoes and other high-yields, can you make them taste back? And .........

The fundamental reason for a desert is that there is no water, and a lot of water can also be an oasis.

No, the desert becomes an oasis and crops cannot be grown or farmed.

I'm sick! If you don't plant this large area of fertile land, you have to go to the sea and the desert to plant rice! The old man is also a master of showmanship.

It's really a person who laughed at his mother again, and the good mouth with abundant water in the interior was used to build houses and trees, and then went to the desert to grow rice.

Grow rice in the desert! Of course. However, it is necessary to divert water from all the rivers in the country to Xinjiang. Then, everything outside of Xinjiang became a desert.

Chinese peasants do not grow grain, mainly importing a lot, rice, soybeans, do not enter the plant.

I think we can try to use it to green the desert, but it will be very difficult to implement it, so let's look forward to it.

Growing rice in the desert costs more than harvesting.

Why should we plant rice with a large amount of water and plant plants with a small amount of water to green the desert due to the lack of water in the desert?

Contemporary Shennong, the saint of the Republic, and his exploits will go down in history.

The fertile farmland is abandoned and rice is not grown, but a lot of manpower and material resources are spent on research in the desert. The good earth is destroyed and the environment is not as good as a year, but they go to the alien planet to explore, hoping that one day the earth will not be able to live and move to an alien planet. A good wife doesn't cherish it, but goes to find a worse lover.

It's dizzy!

After planting for three or five years, you can plant trees.

It can only be said that it may be realized in the future, but the current science and technology are still limited, and it cannot be done in this way.

Don't be inflated, do everything and be realistic.

In another century, let's wait for the desert to become fertile land.

This Chinese guy named Tengfei has grown rice in the desert with his efforts. The success of growing rice in the desert has also led to an investment of up to 300 million yuan. And Tengfei planted rice in the desert, which also improved the land utilization rate of the desert, so people called Tengfei the second Yuan Longping.

Soaring, he planted rice in the desert and made full use of such wasteland as the desert, which was very successful.

This is Takeoff. Tengfei led the scientific research team to plant 500 acres of rice in the first phase of the Horqin Desert, and expanded to 5,000 acres in the second phase. It has obtained 15 patents and 4 inventions.

China is a populous countryThe need for food has always been one of our top concerns. The importance of food is self-evident, and rice is one of our staple foods.

Rice needs to survive in fresh water. WhileNow, with the efforts of Academician Yuan Longping and Professor Chen Risheng, rice can also be grown in saline-alkali land. China's saline-alkali land has reached hundreds of millions of acres.

Once the sea rice production is high, the value to China will be immeasurable. On this basis, millions of people will be fed. However, the process of Haimi's research was extremely difficult and arduous.

It is called "seawater rice" not because it is planted on the sea, but because it is a common name for saline-tolerant rice. This rice can be grown in seaside tidal flats, and short-term soaking in seawater will not affect it. So what happens when planted in saline soil?

Come, Qingdao Seawater Rice Research and Development Center Bainidi Experimental Base will tell you that the first batch of saline-alkali tolerant rice harvesting evaluation - the highest yield per mu kilograms!

Seawater rice is relatively salt-tolerantProbably, it is suitable for planting in the delta of the estuary at the junction of brackish and fresh water, seaside tidal flats, low-lying saline-alkali land and other places. However, seawater rice tends to be a wild rice type, and the yield is very low, only about 200 kg per mu.

The most basic experience is that fresh water is required for salt washingThe salt content of the irrigation water is below, and the irrigation amount is about 1000 m3 667 m2, which reduces the salt content of the soil to the following. After 1980, tidal flat rice was widely promoted in the coastal zone of Jiangsu, and the yield could reach 800 900kg and 667m2. The index of freshwater salt washing did not change, and the increase in yield was mainly due to the improvement of varieties and the popularization of accurate quantitative rice cultivation technology based on the rice leaf age pattern.

At the same time, controlling the salt content at or below is a necessary condition for the normal growth of existing rice varieties, and it is also a necessary condition for the development of rice planting in freshwater irrigation and salt washing land.
