Zhang Chen made a temporary decision to announce Hefeng Rice.

As a result, Hefeng rice, which has added antiviral ability, has not had time to verify its specific yield.

Before dinner, Zhang Chen took the seeds and came to the laboratory.

He plans to start processing rice seeds now.

Zhang Chen inspected the laboratory and found that the equipment and reagents were complete.

So I immediately started to do it.

First, soak the dried seeds of Hefeng rice with 100 grams and soak them for about five minutes.

The seeds were then removed and some aqueous solution containing imidacloprid wettable powder was prepared.

For the next 48 hours, the seeds need to be soaked with this solution all the time.

Finally, when about 80% of the rice seeds have germinated and turned white, they can be sown.

The seeds treated in this way can not only improve the emergence rate of rice, but also improve the ability of rice to resist diseases and pests.

It can effectively control seedling disease, dry tip nematode disease and early gray planthopper.

After soaking the seeds, Zhang Chen took off his gloves, washed his hands, and walked out of the laboratory.

He thought that if the seeds were processed now, the rice seeds would begin to germinate by this time the day after tomorrow, and after that, the seedlings would need to be raised.

Seedling cultivation is divided into wet seedling cultivation and dry seedling cultivation method, and the dry seedling cultivation method is generally used in the laboratory.

Dry seedling rearing is carried out on a fertile and loose seedbed using a plastic floppy disk or paper tube.

The sowing time of this seedling raising method is not limited by water source, and the operation is convenient, and it is suitable for cultivating open and closed film dry seedlings.

The width of the bed is about 1.5m, and the middle height of the arch is about 25~35cm, which is made of bamboo or iron wire.

The two sides are covered with a layer of semi-plastic film, overlapping 20~30cm on the arch shed, and uncovered from the top when ventilating the seedlings.

From the middle of the roof opening to ventilate the seedlings, the operation is very convenient, and it is very convenient for fertilization, watering and spraying.

The benefits of this seedling raising method are very obvious.

The temperature and light in the bed are evenly distributed, the seedlings grow neatly, and the seedling rate is relatively high.

At this time, moisture management is particularly important.

Moreover, it should be watered in time to prevent the seedlings from dying when the film is removed, and a reasonable humidity should be maintained during the emergence of the seedlings.

After the rice grows to a height of about 10 centimeters, it can be dug out with soil and then divided into the experimental rice field.

When planting, it is necessary to control the spacing.

Generally speaking, the spacing between every two seedlings should be about 15 cm, and the row spacing should be about 20 cm.

In the process of planting, it is necessary to pick out some seedlings that do not grow well.

In fact, rice is suitable for growing in a place with sufficient light, and if there is insufficient light, it is not easy for rice to be budded, which will affect the yield.

In addition, it should be noted that during the growth process of rice, the demand for nutrients is relatively large.

Therefore, in the process of maintenance, it can provide balanced nutrients for rice, which can improve the growth rate of rice.

Another trick is to apply some nitrogen fertilizer when the rice is growing faster.

And when the scion is made, phosphorus and potassium fertilizers need to be used, which can increase the yield of rice.

However, when Zhang Chen verified Hefeng rice, he did not use any fertilizer at all.

I don't know if the application of fertilizer will increase the yield of rice again.

However, this time, Zhang Chen estimated that he could only participate in the seedling stage.

Before the second phase of the clinical trial in Shaocheng People's Hospital, he still needs to rush back to Shaocheng.

Therefore, a series of experiments such as rice seedling transplanting will be handed over to Academician Yuan Zhiguo.

In the Nanfan base, it was inconvenient for Zhang Chen to take out the growth factors directly.

This kind of sharp weapon still needs to wait until the right time to take it out, otherwise it will definitely cause unnecessary trouble.

On the other hand, there is no way to mass-produce this growth factor at the moment, and this is not one of those fertilizers, which can be mass-produced casually.

And this verification in the Nanfan base, its scale is not small, and the growth factors required must be massive, and Zhang Chen can't afford it at all.

If growth factors are not used to accelerate the growth of rice, then even Hefeng rice, its growth cycle will take one and a half months.

That's pretty good.

The normal growth cycle of early-season rice is three months, while the growth cycle of late-season rice is more than six months.

Relatively speaking, the growth cycle of Hefeng rice has been shortened by half.

But Zhang Chen definitely wouldn't choose to spend a month and a half here.

The main purpose of his visit this time was to personally send Yuan Lao some scientific and technological products that could improve his physique.

When people reach their age, they will inevitably be sick, but now Zhang Chen has the ability to remove this pain.

He couldn't bear to be tortured by various physical diseases all year round for such a talented person who had made outstanding contributions to the country.

When Zhang Chen walked out of the laboratory, he saw Zhang Yue chatting with Academician Yuan Zhiguo.

Yuan Zhiguo saw Zhang Chen come out, and a smile bloomed on his face.

Li Bozhan had already told him about Hefeng rice.

He really thinks that the young man in front of him is very good, and he can make such epoch-making scientific research achievements as Hefeng rice and Hefeng soybeans.

In his eyes, there is a reason why Zhang Chen can produce such great results.

Other young people, at this age, are just greedy for pleasure.

And Zhang Chen is different, he is very hard-working.

No, I just came to the base and plunged headlong into the laboratory.

"Xiao Zhang, don't be too tired, just arrived at the base, the experiment matters, let's rest for a while."

"Old Yuan, it's nothing, I'm just soaking the seeds."

Facing Yuan Zhiguo, who always had a peaceful smile, Zhang Chen could feel that it was very comfortable to talk to him.

Yuan Lao didn't have any sense of oppression as a superior, and it was estimated that he would definitely be very happy as his student.

Zhang Chen thought so in his heart.

"Let's go, take you to taste the canteen of our base, and after eating, you can also take this girl to the beach for a walk."

Yuan Zhiguo was full of smiles, led the way first, and led the two to the cafeteria.

After eating, Zhang Chen and Yuan Lao said goodbye.

The two walked around and came to the beach.

Blowing the warm and humid sea breeze, breathing in the slightly salty fresh air, and surrounded by beautiful women.

At this moment, Zhang Chen felt extremely relaxed.

He didn't think about the system, he didn't think about whether there would be gangsters, he didn't think about anything else.

Just take a quiet walk.

Zhang Yue walked beside Zhang Chen playfully with her hands behind her back.

At this time, when she saw Zhang Chen's enjoyment, she suddenly felt a little distressed.

"Zhang Xiaochen, you haven't been so relaxed for a long time, haven't you?"

Zhang Chen was stunned for a moment.

In retrospect, it really is.

Since I inexplicably had a system, I think about earning points as quickly as possible every day.

Since then, there has been no leisure time at all.

Even my favorite playful Dota has not been touched for a long time.

"yes, it's been a long time since I've been so idle."

Zhang Chen glanced at the sunset, and there were large and small ships passing by on the sea from time to time.

Not far away, there were three or two seagulls rowing from time to time.

Looking at the beautiful picture in front of him, Zhang Chen felt something.

He thought that if the system appeared to him, it would be a test and a responsibility.

Whether the motherland can become stronger and whether people will be happier depends on him.

He sighed and said, "This world is very beautiful, and I really want to keep this beauty as much as possible, this is probably my responsibility." ”
