That night, Chen Cheng and his family first took a motorcycle from the village to the county seat, and then took a bus from the county seat to the provincial capital of Haizhou.

Only in the provincial capital did the plane fly back that night.

Deng Xing naturally also knew about Chen Cheng's plagiarism on the Internet, and he wanted to come over to comfort him, but seeing that Chen Cheng seemed to be fine, he gave up this idea.

Sitting on the bus, Chen Cheng texted back to the people who cared about him one by one, then leaned back on the seat and looked sideways at the shadows of the trees flashing outside the window.

Zeng Lao's sentence "Shake the hand with the king, what is the honor and disgrace in the rest?" It gave him great psychological comfort.

Have a clear conscience, honor and disgrace are not shocked.

It's not about not fighting, not fighting, but keeping a peace of mind.

Whew-wah screams usually die early.

The kind of person who silently accumulates strength and then kills with one move is the master.

Now for him, the priority is to improve the salinity tolerance of this batch of premium rice, and as for Freman, he will have to wait until he has time to clean him up.

That night, Chen Cheng and Deng Xing separated at the airport, Deng Xing and the two returned to Hannan Province, and Chen Cheng flew back to Hanxi Province.

The main reason is that in addition to screening high-quality seawater rice pollen, he also has to recombine and improve them. It is inconvenient to take Deng Xing to the laboratory.

When I returned to the Agricultural University, it was already past three o'clock in the morning.

Chen Cheng walked into the lab and was ready to start work, he had been resting for a few hours on the plane.

He sat down and lined up the collected bags of pollen from the wild seawater rice male flowers on the bench.

"System, analyze their traits and screen out the optimal pollen."

【Okay】

After the scan, the supercomputer began to calculate.

[After analysis of 8 varieties of wild seawater rice from left to right, No. 2 and No. 7 traits were the best]

"Tell me more." Chen Cheng said.

[The traits of No. 2 wild seawater rice are low plants, good lodging resistance, full grains, high yield, and leaf-changing characteristics. The disadvantage is that the taste is poor and the growth cycle is long]

Chen Cheng flipped the pollen tape over and looked at the label on the back.

This is a plant they found at the mouth of a river by the sea, and thinking of its harsh growing environment, Chen Cheng understands why it has these traits.

The river channel at the mouth of the sea is often irrigated under the tides, so this seawater rice has to be soaked in seawater for a period of time from time to time, which makes it low and resistant to lodging.

The plants are low and have a long growth cycle, so there are naturally enough nutrients stored in the rice, so the yield is relatively high.

As for the "leaf-changing characteristic" that stumped Chen Cheng, this was the first time he had heard this term.

[Leaf-changing characteristics refer to the trait that annual herbaceous plants have the trait of growing new leaves to replace old leaves]

Chen Cheng understood a little.

Generally speaking, the number of leaves that grow during the life cycle of herbaceous plants is roughly fixed. For example, most rice plants can only grow 12-19 leaves in their entire life cycle.

The leaf-changing characteristic means that the number of leaves is not fixed, and the old leaves that may be born fall off and some new leaves come out.

It's like trees.

"Oh! It is supposed that after the seawater rice has been submerged for too long, and the leaves have died, it has reproduced some new leaves. ”

Growing more leaves means consuming more nutrients, which is not a good thing for crops that want to be fruitful.

[The traits of No. 7 wild seawater rice are tall plants, strong roots, branches and leaves, large rice ears, high yield, and short growth cycle. The disadvantage is that the taste is poor]

This wild seawater rice was discovered by Chen Cheng during the day in a swamp. The swamp is full of weeds, and in order to compete for survival, it has to grow taller and taller.

The short growth cycle and large ears of rice should be its advantages in order to strive for more opportunities to reproduce.

Creatures are like this, constantly changing themselves and adapting to their environment in the competition for survival.

"What is their salt and alkali tolerance?" This is the issue that Chen Cheng is most concerned about.

[No. 2 salinity resistance 10.1, No. 7 salinity resistance 10.5]

"Isn't No. 2 often flooded by the sea? With such a high salt concentration in seawater, its salt alkali tolerance is not as good as that of No. 7 growing in swamps? Chen Cheng asked.

[No. 2 is often flooded by seawater, but most of the time it absorbs fresh water from the river. Marshland No. 7 is rich in high salinity brought by the wind-blown sand on the seaside, and there is no water flow, so it is more tolerant to salinity.

Chen Cheng nodded slightly.

From the current point of view, the excellent traits of No. 7 wild seawater rice are better than those of No. 2, especially the saline-alkali tolerance is more prominent.

Zeng Lao's team developed the world-famous special grade rice, with a yield of up to 1,500 catties per mu. Because of the continuous increase in yield, the plants of premium rice must grow tall and thick in order to withstand the ears of rice and not lodging.

The plant is tall and the ears are large, and these traits are just the same as those of No. 7 seawater rice, which means that it is not too difficult to combine genes.

"The genetic combination of No. 7 and Premium Grade rice retains the excellent traits of high salinity tolerance, high yield, lodging resistance, and resistance to diseases and insects."

[This experiment will cost 100,000 reputation points, do you want to start the experiment?] 】

"Let's go!"

Chen Cheng watched as the DNA double helix chain of the premium rice was marked with the color of different segments, and then it was broken down into many segments, floating in the void like this.

The same is true for the DNA of No. 7 wild seawater rice, but it has fewer color markings, indicating that it has fewer excellent traits than premium rice.

Immediately afterwards, DNA fragments, representing high salinity tolerance, were embedded into the DNA strand of premium rice, and then recombined to form a new rice DNA strand.

"Simulate its growth and analyze the traits."

Looking at the DNA slowly spinning in the air, Chen Cheng was a little impatient.

This means that it is a completely new rice variety.

Two minutes later, the supercomputer simulated its growth.

[The yield per mu is 1200 catties, the salinity tolerance is 10.2, and the taste is poor]

"Why does it still taste bad?!" Chen Cheng frowned.

[Regardless of the salinity tolerance of the plant, minerals always accumulate in the plant and inevitably accumulate in the rice]

Chen Cheng buckled his head and blamed himself for not even thinking of such a simple question.

It's almost dawn, and this is the time when people are most tired.

He is not a god, so naturally he will feel dizzy.

"I'm afraid the addition of the mineral operation hormone will only reduce the taste even further, right?"

Chen Cheng rubbed his face with both hands, making himself a little sober.

"The last time I added the mineral Operaton to the generation of seawater rice that had been old in the past, the leaves withered after a few days, and then the plants died."

Chen Cheng thought back to all the research he had done before, trying to find a solution.

"Leaf wilting? Then let it grow new leaves! Chen Cheng slapped his head.

"Doesn't No. 2 wild seawater rice have the property of changing leaves?"
