That night, lying on the bed in the guest house of the National Hybrid Rice Research Institute, Chen Cheng's mood could not be calmed down for a long time.

Zeng Yinghua, who is now in his eighties, (the first name and surname, and even the deeds cannot be related, so I changed my name, and once again stated that this is an alternate world, please do not associate it.) The audit is too strict⊙ 〈⊙), not only Taishan Beidou of Huaxia hybrid rice technology, but also the first person in the world's hybrid rice technology. Having picked the pearl at the pinnacle of hybrid rice technology, he is still thinking about the country's food security.

Let him admire and move him, this is the charisma of the great man.

The reason why Huaxia was able to get out of the suffering and embark on the road to take-off was precisely because of the batch after batch of heroes like him, who worked hard and made selfless dedication in their respective posts.

Behind the rise of great powers is the baton forged by the painstaking efforts of generation after generation, which has been passed down one baton after another.

Now, the baton is handed to him.

Thinking of this, Chen Cheng, who couldn't sleep, sat up directly, mobilized the system, and began to query the cultivation and hybridization technology of saline-alkali tolerant crops in the supercomputer, and learned hungrily.

Since you can't sleep, let's use it to study.

The next day, Zeng Lao took him to visit the first generation of seawater rice varieties in their experimental field.

What made Chen Cheng more envious was that Zeng Lao's experimental fields in their research institute were numerous and large, and some important experimental fields were surrounded by walls on all sides, with sprinkler devices and fluorescent lamps, as well as movable roofs.

In this way, the impact of the environment on the experimental product is minimized.

It is really worthy of the title of "National Hybrid Rice Research Institute".

"If the Agricultural University had this kind of rice experimental field, then I would not have encountered the difficulty of the experimental rice on duty being blown down by the wind." He thought boredly.

to the first generation of seawater rice experimental field. This is a separate experimental field, and the transparent plastic shed on the top is tightly covered, and a hot air comes from the pavement.

"This batch of seawater rice was planted late, and we were afraid that the temperature would affect the yield, so we deliberately built a roof." Zeng Lao explained.

Chen Cheng nodded.

It's rice grown in greenhouses.

Taking a closer look, this batch of seawater rice has passed the flowering stage and has just entered the critical stage of the grain filling stage.

In agricultural technology, rice growth is generally divided into eight periods, namely seedling stage, transplanting stage, tillering [niè] stage, jointing stage, booting stage, heading stage, flower pollination stage, and grain filling stage.

The grain filling period is from the beginning of the grain filling to the end of the mature harvest, which generally takes about 20 days. During this time, the white color slurry is continuously formed in the grains, and the starch in the grains continues to accumulate, and the dry weight and fresh weight of the grains continue to increase.

The grain filling period is the final period for rice growth, and it is also an extraordinary period related to rice yield.

Chen Cheng observed that there were automatic water outlets and drains at the edge of this experimental field, and the water outlets were connected to the pool in front, and there were experimenters preparing fertilizer and water nutrient solution by the pool.

Because rice is sensitive to water during the grain filling stage, it is necessary to constantly adjust the water content of the experimental field.

At the beginning of rice filling, a shallow water layer should be maintained to meet the water demand of rice. In the middle of grain filling, the intermittent irrigation method should be adopted to keep the field moist. In the later stage of grouting mainly dry, it is beneficial to improve root activity, prolong leaf life and prevent lodging.

An extended small platform was built at the edge of the experimental field, so that Zeng Lao could observe the growth of rice up close without going to the field.

He beckoned Chen Cheng to his side, gently supported an ear of rice with his hand, and carefully counted the number of rice grains.

The ears of rice that have not yet started to fill are very small, and the grains are sparse and shriveled.

"Xiao Chen, you see, this is our first generation of seawater rice, with small ears and only 60-80 grains."

Chen Cheng asked: "Wouldn't that be a very low yield?" ”

Because of conventional rice, one ear has 120-200 grains.

Zeng Lao sighed: "We have searched all the wild rice along the coast, and the plants with saline-alkali tolerance genetic characteristics that were only discovered in some villages in Haizhou Province are the first generation of seawater rice after being crossed with our premium rice after conventional cultivation and screening.

However, we found that after hybridization, they only complemented some of their excellent traits, such as body size and salinity tolerance, but they could not eliminate the rough and bitter taste of wild seawater rice. ”

After speaking, Zeng Lao recruited someone to get a few seawater rice seeds.

The rice in the experimental field has just begun to fill the grain, and there is nothing in it, and there is no taste.

Chen Cheng peeled off the husks of rice seeds, put them in his mouth and chewed them carefully, a faint astringency came, and the tip of his tongue could feel its rough taste like grains of sand.

If it is made into rice, it is indeed not something that people can eat.

After carefully observing the seawater rice plants and comparing the pictures of wild seawater rice, Chen Cheng roughly understood the current situation.

Wild seawater rice plants are very short, the ears are so small that even the mature ears cannot bend the stalks, and the leaves are narrow and narrow, looking like weeds.

Zeng Lao has studied most of his life, and has cultivated a very good special grade rice, the rice stalk is thick, the leaves are wide, the rice ears are huge, the mu production capacity reaches more than 1400 catties, and the traits are very good.

However, even with such excellent traits, after crossing with the selected wild seawater rice, the traits were still not fully assigned to the wild seawater rice.

It can be seen how strong the disadvantage genes of wild seawater rice are.

And it's no wonder they're not.

These traits are the most suitable genes for survival that have been accumulated over thousands of generations under harsh living conditions.

"So now your goal is to improve the taste and yield of seawater rice?" Chen Cheng asked.

Zeng Lao nodded and said, "After you released the paper on plant mineral operants, I immediately arranged for researchers to test wild seawater rice and hybrid seawater rice, and found that there was no mineral operans in seawater rice.

I intuitively feel that Mineral Operator is the only solution to improve the taste of seawater rice, which is why I am in such a hurry to ask you to come. ”

Chen Cheng said: "We can now look at the chemical composition of seawater rice body fluids. ”

"Let's go, let's go to the lab."

After speaking, Zeng Lao took Chen Cheng's hand again and led him to the experimental building.

After looking at the chemical substance map of seawater rice, Chen Cheng confirmed that there was indeed no mineral operanin in seawater rice.

Back in Zeng Lao's office, Deng Xing made tea for him and Zeng Lao, while Chen Cheng took out his laptop from his schoolbag and called up the experimental analysis data of mineral operants.

"Elder Zeng, come and see."

Chen pointed to Zeng Lao and pointed to the picture of Chen's polyamine chemical bonds on the screen.

Zeng Lao glanced at it, immediately turned his head, looked at him in surprise, and said, "You haven't announced the chemical bonds of Chen's polyamine to the outside world, but now you show it to me." Aren't you afraid that I'll steal your technical secrets? ”

After saying that, he laughed heartily.

Chen Cheng also laughed.

Zeng Lao is like this, when he is engaged in academic research, he has a serious face, but Dan always suddenly makes a joke with you when he is not expecting.

Chen Cheng said: "Zeng Lao, you are a master of agricultural technology research, and it is my honor to be able to take it out for you to check." Moreover, I decided to share the results of mineral operation hormone research with domestic industry experts a long time ago. ”

Zeng Lao looked at Chen Cheng with a smile on his face and nodded with satisfaction.
