Time flies, the rice will soon mature, and now when you go to the renovated greenhouse, you can see that almost all the rice is already hanging with golden ears of rice.

Countless people want to visit Yangzhou's rice base, and the president, the dean of the School of Life Sciences, and some experts from the Academy of Sciences have come to visit the site several times.

Experienced agronomists can confirm how much yield there is in an acre just by looking at an ear of rice.

Yang Zhou didn't lie at all a month ago, in a normal paddy field, one mu of field, the minimum yield of mutated giant rice is more than 2,000 kilograms.

The most exaggerated thing is that some rice is still planted on saline-alkali land.

However, the yield of these rice is limited, each plant has only a small number of ears, and the yield per mu is estimated to be less than 200-300 kilograms, which is not one-third of that of normal rice.

But this is also a remarkable scientific research achievement, and there is very little rice that can survive in saline-alkali land.

Now the problem is whether we can survive in such a land, not how much we can produce.

Even if the yield per mu is only 200 kilograms, the total resources of saline-alkali soil in China are about 1.48 billion mu, of which the area of modern saline-alkali soil is 550 million mu, and the residual saline-alkali soil is about 670 million mu, which does not count about 260 million mu of potential saline-alkali soil.

Taking Beihe as an example, the salinized soil area of Yanzhao Land reaches 9 million mu, of which 3.5728 million mu is salinized soil in the coastal front, mainly distributed in Tangshan, Cangzhou and Qinhuangdao.

If this land could be used to grow staple foods, countless more grains could be produced every year.

Of course, it is not only the survival of rice that restricts saline-alkali land, but also the problem of water supply.

There are two conditions for the formation of saline-alkali soil: first, the climate is arid and the groundwater level is high (higher than the critical water level); The other is low-lying and there is no way to drain the water.

Groundwater contains a certain amount of salt, such as its water surface is close to the ground, and the area is relatively arid, due to the capillary action to rise to the surface of the water evaporation, it will leave salt, accumulate over time, the soil salt content gradually increases, forming saline-alkali soil;

There is also the seaside, it seems that there is no shortage of water at the seaside, but in fact, seawater cannot be used for irrigation, and in fact, if you want to achieve large-scale rice cultivation in saline-alkali land, there are still many problems to be solved.

But in any case, Yang Zhou's mutated rice is a good start, and a part of the saline-alkali land can be fully utilized.

What's more, there is upland rice grown on dry land.

The yield per mu of normal giant rice is more than double that of the previous one, which is also equivalent to the land area being doubled compared with before.

Now it depends on how the rice tastes and whether countless farmers can choose this high-yielding giant rice.

Yang Zhou was busy for a few days, and originally planned to ask the villagers of Qiankou Village to help with the harvest, but when the security guard learned the news, he was afraid that the rice seeds would be leaked, and after asking for instructions, he decided that they would come to harvest in person.

All rice seeds are closely guarded.

Most of Yang Zhou's four guards were born in peasant families, and they were proficient in harvesting rice.

The rice in the rice base is slightly more complicated, and each group of rice is harvested separately, and then threshed and dried separately and weighed.

The whole process was also filmed by the CCTV documentary team, and Yang Zhou just stood aside and watched everyone busy.

Some doctoral and graduate students, under the leadership of Tang Yue, recorded all the data, and finally incorporated it into Yang Zhou's latest paper.

After finishing everything, Yang Zhou prepared a special event in Yang Zhou in Qiankou Village.

That's the Mutant Rice Tasting Conference.

Teachers from Qingbei University, some biologists, academicians of the Academy of Sciences, students of Qingbei University, and media reporters were also invited to participate in the conference.

Everyone will give a fair score to all the rice.

Among them, it is also mixed with the more expensive premium rice on the market.

Yang Zhou hopes that through this event, everyone will know that the taste of the rice he has researched is no worse than that of some top rice.

Of course, before this, Yang Zhou and Tang Yue had already tasted it quietly.

Of the thousands of varieties of rice, about 100 varieties of rice with special characteristics have been selected, which either taste good but have slightly lower yields, or are adapted to various types of land, and some have particularly high yields.

It was precisely because after tasting it and knowing that the mutated rice tasted excellent, Yang Zhou wanted to do this activity.

Anyway, these shots have to be put into the documentary, and even Wang Bingbing said that the rice materials filmed plus this event can be on the news for 30 minutes, and it is even more necessary for Yang Zhou to do this event.

In the past, after hybrid rice came out, there were not many people who planted it because of the taste problem.

Because at present, food is not very scarce, because of the relationship between many grain merchants, they even import a lot of rice from Annan every year, and it is more cost-effective to import than to grow it yourself.

Farmers grow long-grain fragrant rice with a good taste although the yield is not as good as that of top-quality hybrid rice, such as Longdao 18, Longdao 21, Longyang 16, Songjing 16, etc.

According to the data released by the National Center for Statistics, all hybrid rice in China will feed 60 million people if the grain yield is increased, and nearly 85% of the grain output in China is not hybrid rice, and the varieties developed by Yuan Lao have a low market share.

However, Yuan Lao's contribution to hybrid rice is the greatest, and hybrid rice is more like a strategic weapon for us.

It is precisely because of such high-yielding varieties of rice that foreign countries cannot control our staple food.

There are also a lot of modern compradors, in a profitable situation, there are countless foreign brands of fragrant rice into China, of course, many brands are just unscrupulous businessmen selling dog meat on the head of a sheep, in fact, these fragrant rice is still domestic, but it is said that it is imported from Annam.

Yang Zhou's successful research on giant rice means that the taste can be compared with fragrant rice.

In the face of higher yields, better taste, wider adaptation to the land, and better disaster resistance, farmers' choices can be imagined.

When the mutant rice tasting conference was held, Yang Zhou followed Principal Hao Yu, and a long line of rice was placed in front of them.

All the rice is placed on the table in a large basin with a score sheet with the sealed name on the front of the basin.

After everyone tastes it, they give the rice a score, the highest score is 100 points, and finally the highest and lowest scores are removed to calculate the average score.

Because I don't know the name of the rice, everyone's tasting is very fair, and according to their own preferences, there is basically no misjudgment.

There are almost 100 pots of rice in total, the front is dry rice and the back is porridge, Hao Yu didn't see the porridge in the back, and said with a smile before he ate it: "The grains of this giant rice are much larger than fragrant rice, will there be a deviation in the final score?" ”

"Principal, we still have a gruel link, eat it all the way, and when it's time to drink porridge, you can't tell which ones are giant rice, and besides, the size of some giant rice is not much different from the normal size." Yang Zhou explained.

"Well, it's very thoughtful, then I'll be a judge!" Hao Yu smiled and nodded.
