Chapter 116

"And..." Cheng Nuo walks to the stall, bumps the bundle of spinach in his hand, and then pretends to observe carefully, and continues to speak.

"When spinach is picked from the soil, in a short period of time, because the cells are not dead, they will also carry out photosynthesis and respiration. Photosynthesis 6CO2 + 12H2O = = C6H12O6 + 6o2 + 6H2O; respiration: C6H12O6 + 6o2 + 6H2O = = 6CO2 + 12H2O. "

"Boss, you said that your picking time was last night. In the absence of light, you would not carry out photosynthesis at all, produce organic matter, but only breathe and consume organic matter. The organic matter content of spinach should be less than that of growing spinach at this time! "

"But!" Cheng Nuo tone turns, push glasses, light a smile way, "I just bumped. According to my years of shopping experience, the weight of this spinach is about 580 grams. Then, according to a formula called Woz zybende, the content of organic matter is about 56 g, which is about 5 g higher than the normal value

What does that mean? It means that after you pick the spinach, the leaves of spinach also undergo photosynthesis for a period of time. In the dark, photosynthesis is not possible at all. So, I dare to judge, boss, the time when you picked spinach was not midnight, but Day time

"The normal growth cycle of spinach is about 37 days, and the time from planting to the present, I just observed that it has been about 41 days. Therefore, I presume boldly, boss, you picked these spinach in the greenhouse one morning two or three days ago. Then it was left outside in the sun for about an hour. Then put it in a dark place to keep it fresh, and finally, take it to this vegetable market and sell it! "

"So I wish there was only one! Boss, what you said is not true! It's not fresh spinach at all Cheng Nuo's voice can not be raised a few minutes, causing people around the side of the eye.

"Boss, I don't know. Am I right?" Cheng Nuo looks at the female boss with a smile.

When Cheng Nuo first saw the bundle of spinach, he was already suspicious.

If it is just picked spinach, the kind of green leaves, is absolutely green light, green to the kind of you panic.

But the spinach that this female boss stands on, did not let Cheng Nuo have that kind of flustered feeling at all.

So he turned on the power and took a simple glance.

Sure enough, with Cheng Nuo's intelligent brain, he quickly deduced the exact time for the boss to pick spinach based on the data in his eyes.

Silence A silent silence

The female boss grew up and looked at Cheng Nuo with consternation. She couldn't say a word.

Because Everything Cheng Nuo said is right!

This batch of spinach was indeed picked in the greenhouse the morning before yesterday. Because it didn't sell out yesterday, so I'll sell it today.

This is also a common situation in the vegetable market.

Those vegetables that are not sold out on the first day and have a lot of surplus will be sold the next day.

Most of the customers will doubt it for a few times, but there is no sufficient evidence. The customers don't doubt him, and they still pay for it happily.

Cheng Nuo is so serious that he takes a lot of data to infer the exact time of vegetable picking. To be honest, it is the first time for a female boss to see him.

The key is That's right!

Are senior high school students so good now? Can you infer so much just by looking at it?

The female boss deeply doubted whether she had read a fake high school!

By Cheng Nuo naked expose, the female boss can not continue to deceive in the past. But she didn't want to lose the business, so she said with an embarrassed smile, "cough, auntie, although my spinach is not freshly picked. But I dare say that in the cultivation process, I have not sprayed any pesticides, absolutely safe, green and pollution-free. Take it back and cook the soup. It's absolutely safe! "

The female boss is still a pledge.

“nonono……” Cheng Nuo pushed his glasses and waved his fingers with a smile. "Boss, you're wrong again."

"The inhibition rate of pesticide residues in your spinach is more than 65%. And the national standard is 50%. Boss, you have exceeded the standard by 10%, and you still said that you didn't use pesticides? " (pesticide residue inhibition rate: under certain conditions, organophosphorus and carbamate pesticides can inhibit the normal function of cholinesterase, and the inhibition rate is positively correlated with the pesticide concentration.)

Cheng Nuo a corner of the mouth, looking at the boss with a thick shock in his eyes, slowly opened his mouth, "boss, do you want me to tell you about the brand of pesticide spraying?"

"No. No need to... " The boss gave a dry smile and forced a smile on her face. She said to her grandmother, "Auntie, I really can't afford to bring this guy with you. You'd better go to another home and have a look."

The female boss is also afraid. So many people watching? His bottom continues to be shaken by Cheng Nuo again, the word-of-mouth that hard to accumulate can be all gone.The female boss also wants to understand that she would rather not do this single business, but also want to get rid of the evil guy Cheng Nuo.

"Well, let's go to another place." Grandma, ha ha, a smile.

For Cheng Nuo's words, grandmother is convinced. Look at the woman boss's face, you can see that Cheng Nuo's reasoning is all right.

It's not fresh and healthy. What's grandma doing here?

So he turned and went to the other stalls.

"Xiaojun, what are you doing there? Let's go." Grandmother saw Jiang Jun in Leng in situ, can not help greeting a.

"Oh, here it is..."

Now Jiang Jun's head is in a daze.

After watching Cheng Nuo Gang's forced performance, Jiang Jun's mind has been echoing a few words.

Tianxiu! ***！ Flower show! Good luck Zhong Shenxiu!

It's so beautiful that the second battalion commander's Italian cannon will explode directly!

There is such operation!!

In Jiang Jun's long-standing idea, is it not just adding, subtracting, multiplying and dividing when you go to the vegetable market?

After watching Cheng Nuo's operation, Jiang Jun felt that he was not qualified to buy vegetables in the market without a college degree!

I haven't seen you for a few months. My cousin has become What a show?

………………

Finally, with the help of Cheng Nuo's ability, after visiting four or five stalls, grandma finally bought fresh, safe, pollution-free, green to flustered spinach.

Then they went around and bought all the vegetables they needed in the vegetable area.

"Come on, let's get some ribs and meat!"

Since grandma has promised to make sweet and sour pork ribs at noon, the ribs must be indispensable.

So they went to the meat market area of the market.

Jiang Jun helped his grandmother carry several bundles of vegetables and followed him with wheezing breath.

Jiang Jun looked at Cheng Nuo in front of him with his hands gently on his face. "Cousin Cheng Nuo, seeing his cousin is so tired, shouldn't he offer to help?"
