Seeing the displeasure on Han Qi's face, Chen Cheng put away his smile and concentrated on checking the situation of the wheat.

He scanned all the information about the whole wheat into the system, and then scraped some rust bacteria from the wheat leaves and put them into a petri dish.

Putting away the petri dish, Chen Cheng asked again: "At present, I think that the situation like yours is more serious, how many acres of wheat are there in the province?" ”

"It's almost 10,000 acres." Uncle Wang said.

This is not a small amount, accounting for one-tenth of the winter wheat in the province of Hanzhong Province.

The main thing is that these wheats are constantly infected with other wheat.

Chen Cheng nodded, got up and said to Han Qi, "Let's go." I'm pretty much done and can go back. ”

"That's the end of it?" Han Qi was a little incredulous.

Chen Cheng said as he walked: "The real research has just begun. ”

Han Qi hurriedly followed and asked, "What are you going to do?" ”

Chen Cheng said: "No matter what you do, you must first control the current condition. ”

"Do you need our Huanong Group to do something?" Han Qi asked.

"I'll naturally contact you when I need you."

was about to get in the car, Chen Cheng suddenly said: "Uncle Wang, I still need your use, Kewei Company's special effect compound fertilizer, can you get me a little?" ”

Uncle Wang said, "Yes." I'll take you to the village committee's warehouse to find it. ”

Successfully got a small bag of compound fertilizer, Chen Cheng and the others rushed to the airport.

When he arrived at the airport, Han Qi originally wanted to go back to Handa with Chen Cheng, but was rejected by Chen Cheng.

"You still have important things to do when you go back to Huanong Group. That is to figure out the ins and outs of Kewei Group's special effect compound fertilizer, and when I have my hands free, let's expose their little trick to him! ”

Han Qi nodded earnestly in agreement.

Back at Henda, Chen Cheng went directly to the laboratory.

He divided the wheat rust bacteria he brought back into two parts, one for Ding Tao, and asked him to do a culture experiment.

Generally speaking, to observe the development and growth process of fungi and bacteria, the laboratory will use culture method and microscopic examination method.

The culture method is to place the target on the medium and culture it in a sterile box. Microscopy is a direct electron microscope.

Spore pathogens, on the other hand, generally use solid medium.

This medium should be able to make the bacteria grow rapidly, produce more high-quality spores, and require that this medium is not easy to cause bacteria to mutate.

The basic preparation requirement is not too rich in nutrients (especially organic nitrogen sources), otherwise it is not easy to produce spores. For example, Streptomyces gray can grow and produce spores well on the medium of glucose-nitrate-other salts, but if 0.5% yeast paste or casein is added, it will only grow hyphae but not spores.

Ding Tao's current culture research and observational research are all for Chen Cheng's basic work to completely defend against this type of germ in the future.

What Chen Cheng needs to do now is to solve the problem of wheat rust in Hanzhong Province as soon as possible.

Entering the laboratory, Chen Cheng adjusted the system and leaned the spores in the petri dish into front of him.

[Scanned wheat rust fungal spores, ripe stage.] 】

[Harm: The pathogen will not only reduce photosynthesis, but also cause a large loss of water in wheat plants, reduce the fullness and filling of grains, make wheat leaves prematurely senescent, and then seriously reduce the yield of wheat]

Chen Cheng called up three chemical molecules produced by different manufacturers that had been analyzed in the system before, and set them to different concentrations to act on the spores of wheat rust fungus. It was used to experiment the effect of triazolone on spores at different concentrations.

In less than a minute, the supercomputer analyzed the results.

The triazolone of the three manufacturers achieved good sterilization effect at a concentration of about 14%. The inactivation rate of wheat rust spores reached more than 80%.

In other words, if it is a direct effect, there is no problem with the effect of Huanong Group's triazolone.

Again, the problem lies in the absorption and operation of triazolone in wheat.

The day before yesterday, Chen Cheng had already studied that the reason why Kewei Group's triazolone can gather on leaves is that after their triazolone enters the wheat body, it attracts the positrons of some active chlorophyll in leaf cells.

Huanong Group's triazolone does not have this kind of microelectronics.

"What kind of chlorophyll electrons are the microelectrons of triazolone combined? Are they positrons or negative electrons? ”

In order to clarify this question, Chen Cheng once again called up the process of combining Kewei Group's triazolone with wheat chlorophyll and observed it carefully.

In the simulation effect, he directly pinched out the triazolone molecule after the chlorophyll binding in the root and projected it separately in the air.

After using virtual chemical bonds to mark the connection of the two molecular clusters, Chen Cheng immediately understood at a glance how they combined.

In the current research of scientists on chlorophyll, the chlorophyll molecule is divided into two parts.

The core part is an inhodolent ring, whose function is light absorption; The other part is a very long aliphatic hydrocarbon side chain called chlorophyll, with which chlorophyll is inserted into the thylakoid membrane.

The more important thing is that the chlorophyll non-relenting ring contains a magnesium atom, and the chlorophyll molecule absorbs visible light through the change of single and double bonds in the non-relenting ring, and the free and adsorption of magnesium atoms is the key to the single-double switching of the non-relenting ring.

The magnesium atom is in the center of the non-pyronic ring and tends to be positively charged, while the nitrogen atom associated with it is negatively charged, so the non-glycoline is polar, hydrophilic, and can bind to proteins.

The system was able to metamorphoscopically show the chemical bonds of chlorophyll and triazolone binding, which made Chen Cheng suddenly discover that their binding was to use the free magnesium atom to make the triazolone functional group containing weakly negative ions and the non-pyronic ring of chlorophyll attract and combine with each other.

When the problem is clear, the technical path is also clear.

That is to ionize the triazolone of Huanong Group with negative electrons.

Thinking of this, Chen Cheng once again called up all the chemical elements of Kewei Group's triazolone pesticide.

One of the common NaCl caught his eye.

0.02% NaCl?

Why do they add such a tiny, but common, compound?

Chen Cheng already had a rough answer in his heart, and then added the same amount of sodium chloride to the triazolone of Huanong Group.

In the second simulation, Huanong Group's triazolone achieved the same effect as Kewei Group.

"This..."

While Chen Cheng lamented that the technical strength of the four major grain merchants should not be underestimated, he also felt a little embarrassed for the technical staff of Huanong Group.

Kewei Group's triazolone product packaging does not contain sodium chloride at all, and its content in its solution is also extremely low.

Perhaps the technicians of Huanong Group did not measure such a low content of sodium chloride at all when they used Kewei Group's triazolone for experiments.

If Chen Cheng hadn't had a system that could directly analyze all the elements, I'm afraid he wouldn't have discovered this and its subtle differences.

Chen Cheng, who had found out the technical method, exited the system and dialed Han Qi.

"Hey, Mr. Han, I found a way to improve your triazolone."
