Since the lotus root leaf cells are too full and too active, resulting in easy ice and rupture in a low temperature environment, whether to reduce the water content in the cell and reduce the activity can solve this problem.

That is, to inhibit the cell activity of the new leaves of the lotus root.

However, the level of cell activity will affect the amount of nutrients it produces, so how to inhibit it and to what extent is the main problem.

This is a dynamic process, and it may be difficult to achieve ordinary experiments, but for Chen Cheng's supercomputer, it is only a matter of minutes.

The first is the choice of hormones that inhibit plant growth.

Common hormones that can inhibit plant growth are: abscisic acid, triiodobenzoic acid, maleic hydrazide, mequartin, and chlorocyanin.

But there are still differences between them.

The effect of abscisic acid can be seen from its name, and its main effect is to promote the shedding of leaves. In addition, it can also make the buds go into a dormant state, and it also has an inhibitory effect on the elongation of cells.

Triiodobenzoic acid is also known as anti-auxin. It can hinder the top-down polar transport of auxin in plants, effectively inhibit apical growth, and affect the growth and development of plants.

Maleic hydrazide can enter the plant through the foliar cuticle, reduce photosynthesis, osmotic pressure and evaporation, and can strongly inhibit the growth of buds.

Ampat quartin is an excellent plant growth regulator, which can inhibit the elongation of crop cells, but does not inhibit cell division, can make plants shorter, thicker stems, and green leaf color, which can make crops drought and waterlogging tolerant.

Cyanthin is a selective herbicide or temporary plant growth inhibitor. It can reduce photosynthesis, osmotic pressure and transpiration, strongly inhibit the growth of buds, and inhibit crop growth and prolong flowering.

They work differently and have different effects when used on different plants. If the concentrations are not well controlled, they can become "herbicides".

It's too much to suppress, but don't you just kill the plant?

At this time, the capabilities of the supercomputer are manifested, and it is required to continuously simulate and try on its own, including the dosage, application method and time point.

After a set of simulations, these data can be obtained.

It's safe, reliable, and efficient.

Five phytostatins, different doses, these conditions were combined with each other, and there were a total of more than 20 simulation experiments, which were completed by the supercomputer in about ten minutes.

Of course, its computing power is sufficient, but it takes a little more time to simulate the growth process.

[According to the simulation calculation, among 25 combinations, an optimal cold tolerance technology for the secondary growth of lotus root was selected]

"Show it up!" Chen Cheng couldn't wait.

[Step 1: After removing the diseased leaves and sanitizing the field water, apply 3% cytokinin and 6% gibberellin to the field water. This step is to promote the growth of new leaves of lotus root as soon as possible.

[Step 2: After the water comes out of the new leaves, drain the original auxin field water and replace it with clean new water]

[Step 3: After the new leaves are fully expanded, apply a combination solution of plant inhibiting auxin with a concentration of 0.02% on the foliar surface every 3 days, and the ratio of the combination solution is 30% triiodobenzoic acid, 45% maleic hydrazide, and 25% cyanoxin]

[Step 4: Continue to apply until the new lotus leaves have a large area of wilting due to extremely low temperatures]

"In the climate of Xiting County, how long can the second round of new leaves be expected?"

[According to the prediction, the lotus leaf can survive normally at a minimum temperature of -5 °C or above]

“-5℃？！”

Chen Cheng knows that the lowest temperature in Xiting County is only about -5 °C, which means that if you are lucky, the new leaves of this season of lotus root can withstand the whole winter!

"What is the yield of lotus root after this simulation?" Chen Cheng asked.

[Harvested after 2 months, the production capacity per mu reaches 3100 catties]

"3100 pounds! Ahem! ”

Chen Cheng coughed twice before suppressing the surprise in his heart.

This completely preserves the yield of lotus roots!

He couldn't wait to get out of the system and get ready to go home and tell his dad the good news.

Just as he was about to turn around, he found that he had been standing in the paddy field, his feet had sunk deeply, and he almost didn't fall into the mud.

Finally coming out of the field, Chen Cheng found that his feet were about to be frozen and unconscious.

He had been standing in the paddy field for more than an hour!

Although the temperature is about ten degrees now, he feels a little cold when he has been standing in the paddy field and being soaked in cold water.

Chen Cheng didn't care about his wet pants and the mud on his legs, so he ran home with his shoes. Before he ran to the entrance of the village, he saw Chen Kang standing at the entrance of the village looking in the direction of the lotus root field.

"It turns out that Dad didn't come home to rest just now, but has been standing here waiting for me."

Chen Cheng felt a burst of emotion in his heart, and then walked over quickly.

"Dad, I've found a solution to the reduced production!" He excitedly declared.

Chen Kang's face didn't show the smile that Chen Cheng was expecting, but he asked in a low voice, "Why are your pants wet?" The legs are full of mud! ”

"No... It's okay. ”

"Hurry back and change your clothes." Chen Kang said in the tone of the head of the family.

When Chen Cheng heard this, he stuck out his tongue like a child making a mistake, and hurriedly ran home with his shoes.

He returned home, changed his clothes, and Chen Kang walked slowly into the courtyard gate.

"Guihua, boil a bowl of ginger soup for your son! The rabbit cub stood in the paddy field for two hours, and he was sure to catch a cold! ”

Chen Kang's voice sounded in the courtyard, and Xu Guihua hurriedly answered.

After a while, a steaming bowl of ginger soup was served.

"Son, come and drink, it's not hot." Xu Guihua shouted.

Chen Cheng picked it up and poured it down in one go.

Ginger soup is a medicinal soup commonly used in rural areas to ward off cold and prevent colds. It is boiled with ginger and brown sugar to make a soup and drink, and it has a spicy taste.

Chen Cheng often drank it when he was a child, and it was slightly sweet with brown sugar, which was not difficult to drink.

After he finished drinking, Chen Kang asked, "You said you found a way, what is the way?" ”

Chen Cheng said: "It is still necessary to remove the diseased leaves, and then sanitize the paddy fields, and then combine auxin and auxin inhibitory to make the lotus root grow lotus leaves again." After two months, it is guaranteed that there will be no reduction in production! ”

"Why do you need to use auxin and inhibition again?"

Engaged in lotus root cultivation all year round, coupled with the guidance of technicians stationed in the village, Chen Kang and his family naturally have an understanding of auxin.

"The main thing is to make the lotus leaf resistant to low temperatures, so that it will not freeze to death due to frost." Chen Cheng said.

"You have learned a lot of techniques, and I don't understand these things of yours, I don't know if Technician Zhang can understand these things, and whether he will agree with your method."

"He's a graduate student, I'll explain it to him, he should understand."

Thinking of today's incident, Chen Kang couldn't help but be a little angry, so he said: "If it doesn't make sense to them, you won't bother to care about them, and our family will use this method ourselves." ”

Chen Cheng said: "The village chief is a little stubborn, but they are all neighbors left and right, watching them do some useless work, and the lotus root yield will be seriously reduced at that time, and I can't help it." ”

Chen Kang sighed, and then quickly relieved.

People are different from others, some people are angry and some are stingy, and the villagers are not a big contradiction, even if they don't support or understand.

Chen Cheng can have such a broad mind under his training, which should be something he should be proud of.
