Professor Andrew seemed happy, probably because of the beautiful pasture.

On the way, Han Xuan was told the habits of many plants, such as the mountain subway line lotus planted with other trees, which may cause the other party to die; Lily of the valley is beautiful now, but the fruits of autumn will be poisonous and so on.

The nearby half kilometer area is used as a living area, and there are no alfalfa plants, and even if there are, they are not infected by the fungus.

Andrew carefully inquired about the specific situation of downy mildew in the pasture, and Han's father suggested that he go to the serious place first, and when he agreed, he would return to the garage alone to pick up the car.

"What a cute shorthair, what's its name?" said Andrew, bending over and petting Chubby's head.

Fat Ding surprisingly didn't dodge, his face was unhappy, but it was true, and when he stopped, he quickly hid to Han Xuan's side, and his big tail rubbed against the boy's lap.

Han Xuan was only wearing a pair of shorts, which made him a little itchy, and he took two steps to the right, and Fat Ding also followed, as if he was pestering him.

Helplessly, the dead fat cat was held in his arms, and Han Xuan said: "Jigglypuff (Fat Ding)." ”

"Looking at it like this, it's estimated to cost fifteen pounds, right?"

"You can't give it too much to eat in the future, especially snacks, because you may get diabetes, bone and kidney diseases. ”

After Professor Andrew finished speaking, he reached out to touch Fat Ding's belly.

This is not unexpectedly slapped away by Fat Ding, and his limbs and tail are shaking together, protesting against this guy who ruined the cat's future and cut off the cat's food route.

Do you want to touch the cat uncle after doing something bad?

No way!

"Look, you see it can't even touch its ribs, that's a sign of being overweight. ”

Fat Ding stopped when he heard this, his two front paws curled up on his chest, and he stared at Andrew with a blank expression, as if asking who couldn't touch the ribs

Andrew saw its natural appearance. Haha laughed: "What a smart cat, it seems to understand me?"

Han Xuan was afraid that the cat would really shake his head, so he hurriedly pinched the fat ding and put it on the ground to let it play with it.

He said: "I will feed it less rations, Fat Ding is just smarter, it can understand what people think in their hearts." ”

"Yes. Animals are people's friends. ”

Andrew pointed to the cattle and sheep in the distance, and sighed slightly: "They are also, in some cultures, before hunting and gathering animals, you must first obtain their permission and thank them for their dedication. ”

"Human beings naturally need to eat and nourish in order to meet their own energy needs, and plants are seasonal, and the energy contained is not particularly comprehensive. Our ancestors set their sights on animals. ”

Han Xuan didn't know why he was saying this, nodded in agreement, Andrew saw his doubt, and explained: "I am a vegetarian, I have not eaten meat since I was thirty-one years old, although I am not against humans eating meat, but I think we should still be grateful to them." ”

It's rare to be able to resist not eating meat. At least Han Xuan hadn't seen it in Huaxia in his previous life, and the only one he knew was Natalie Portman. The girl I met once in New York.

Now that he finally saw the living, Han Xuan's eyes were full of admiration, knowing that this old man was educating himself, and nodded seriously: "I know, so if you don't eat meat, will there be any changes?"

"What's changed, now there are a lot of trace elements. It has been able to be synthesized artificially. Andrew's expression was like crying and laughing, his tone was helpless, and he struggled to explain for a long time: "I'm sorry, do you know trace elements? ”

The corners of Han Xuan's mouth twitched. "I'm a first-year student at Brown University, Mr. Andrew. ”

"What?"

"Are you Chinese all from Mars?!"

……

A few years ago, there was a Chinese in Australia, Mensa IQ test result was 230 points, he studied mathematics at the age of two, entered middle school at the age of 8, took the American SAT (American college entrance examination), the mathematics part of the test scored a full score of 800 points, and he got a high score of 760 points.

He finished college mathematics at the age of 9 and became the youngest gold medalist in the International Mathematical Olympiad at the age of 13.

This is what Han Xuan learned from Professor Andrew.

There is never a shortage of geniuses in the world, but Han Xuan means that a genius who is a little bit stupider than him is the smartest.

I suddenly learned the bad news today, and I couldn't come back to my senses for a long time, thinking that Hawking's IQ was only 160, Einstein's IQ was only 200, and this product was as high as 230!?

Sitting in the back of a Humvee SUV, staring out the window and sighing.

Father Han didn't understand that he had gone home, but it had only taken more than ten minutes, how could his son have become like this, and turned his questioning eyes to Professor Andrew.

Andrew didn't expect his words to be so lethal, so he turned around and comforted: "Don't be discouraged, you are already very smart, smarter than 99.999% of the people in the world." ”

"Mending the knife, this is definitely a mending knife!"

Han Xuan's mind instantly reflected this sentence.

It's just a little depressed, and when I saw my father's worried appearance, I rubbed my face and regained my smile.

I thought to myself, I am the most special person on this planet

The car drove west for seven or eight minutes, passing by the foot of the hill where the black-nosed sheep were staying, and unexpectedly did not see their cute figures.

Further on, I found a alfalfa bush that had not been eaten by cattle and sheep, and it was gray and white, the plants were shorter than the rest of the place, and some of the alfalfa leaves were yellow and dead.

Some leaves still have traces of being eaten by insects, Professor Andrew put on reading glasses, picked a piece and put it in the palm of his hand, observed it for two seconds, and affirmed: "It's not just downy mildew, alfalfa resistance has decreased, and now there are aphids." ”

Han Xuan didn't care about downy mildew, as long as the forage was safe, he could buy it all from other pastures.

However, aphids are a small thing that is troublesome, they can reproduce for dozens of generations a year, and the number is completely increasing exponentially, if you don't kill them, it won't take long for the whole pasture to have intact plants.

Moreover, the vegetable base is still built nearby, and it is a big trouble to infect the past.

"Is there any way to cure them? I mean the safe kind, we don't use pesticides on our farms. ”

Han Xuan was just about to speak, but he didn't want to be asked by his father first, and the words came to his mouth and then held back.

"It's a little bit better than I thought, but when the temperature drops in the fall, the downy mildew will naturally die. ”

"If you are not at ease, you can sprinkle some organic fertilizer and spray it once a week with a small amount of HILOT Kai cream diluted 600 times, but in this way, you can't feed the livestock for a long time. ”

Professor Andrew held the leaf in his hand in front of the father and son: "As for aphids, it is even simpler, in the book "Plant Protection Products and Substances Allowed to Be Used in Organic Crop Cultivation", published a few years ago, it is marked that sulfur is an organic mineral, and it is only necessary to spray sulfur with water. ”

"I think that if there are aphids, this is the only one that needs to be killed quickly, and the grass that is fed to the livestock must be plucked from the leaves with downy mold, otherwise they will have diarrhea. ”

Han Xuan suddenly felt that Professor Andrew was tall again, and at the same time as his father, he blamed Martinez for his own lack of learning and skills.

Thinking about it, the image of passing by the foot of the mountain just now suddenly came to my mind.

"Eating will make you diarrhea, those cute black-nosed sheep, won't be" (To be continued.) )
