Ye Tianfeng is actually very familiar with field potatoes.He has seen this beautiful plant in many places.

All of a sudden, all the knowledge about field potatoes poured into his mind——

Field potato, long cylindrical tuber, vertical growth, up to 1 meter long, white when the section is dry.

Stems usually purplish red, dextral, glabrous.Leaves simple, alternate at the lower part of the stem, opposite above the middle, rarely 3-lobed; leaf blade variable, ovate-triangular to broadly ovate or halberd-shaped, 3-9(-16) cm long, 2-7 wide (-14) cm, apex acuminate, base deeply cordate, broadly cordate or subtruncate, margin often 3-lobed to 3-parted, middle lobe ovate-elliptic to lanceolate, lateral lobe auricular, rounded , nearly square to oblong; when young, the leaves are generally broadly ovate or ovate, and the base is deeply cordate.There are often bulbils in the leaf axils.dioecious.

The male inflorescences are spikes, 2-8 cm long, nearly upright, 2-8 are born in the leaf axils, and are occasionally arranged in a conical shape; the inflorescence axis is obviously zigzagging; the bracts and tepals have Purple-brown spots; the outer tepals of male flowers are broadly ovate, and the inner ones are ovate and smaller; stamens 6.Female inflorescences are spikes, 1-3 inserted in leaf axils.

Capsule not reflexed, triangular oblate or triangular round, 1.2-2 cm long, 1.5-3 cm wide, with white powder on the outside; seeds inserted in the middle of the axis of each chamber, surrounded by membranous wings.

Flowering from July to September, fruiting from September to December.

The living habit of field potato is that it likes high temperature and dryness. The tubers start to germinate at 10°C, the suitable temperature for stem and leaf growth is 25-28°C, and the suitable ground temperature for tuber growth is 20-24°C. Low temperature of 15°C.Short days can promote the formation of tubers and subtilis.

It does not have strict requirements on the soil, but sandy loam soil with fertile and loose soil, strong water retention capacity and deep soil layer is the best, the groundwater level is below 1 meter, and the pH of the soil is between 6.0-8.0.Attention should be paid to the preparation of the soil. Stones with a diameter of more than 1 cm should not be mixed in the soil, otherwise the field potato tubers will be severely forked and the root shape will not be beautiful.

How is it so detailed?

Could it be that my head suddenly turned into an encyclopedia?
How come all the information about it pops up in my mind once I focus on the potato?

That's right, I was very familiar with field potatoes before, but it's impossible to be familiar with it to such a fine level?
Ye Tianfeng was dumbfounded at his own thinking for a moment: Oh my God!Is this still human thinking?I am afraid that the computer brains of alien advanced creatures are not so powerful, right?

Suddenly, Ye Tianfeng seemed to see a disc in the sky above his mind, a purple disc, that's right!The purple disc that is the same color as the purple bamboo is that mysterious disc!

"What's the matter with you?" At this moment, Gao Zhuang's mother suddenly asked Ye Tianfeng.

Ye Tianfeng returned to reality as if suddenly awakened, knowing that Gao Zhuang's mother suddenly became stupid when she saw him.

"It's okay, Auntie, I'm sorry, I suddenly thought of something, but I can't think of it all at once, it seems to be about Uncle Gao's condition," Ye Tianfeng quickly explained, "I'm also going to see the field potatoes in the yard outside. , see if I can remember, and help Uncle Gao recover."

So it is!Gao Zhuang's mother was moved in her heart.She thought to herself: But Ye Tianfeng did this because he wanted to cure his old man.

I thought he was... Sigh!

"Well! Thank you!" Gao Zhuang's mother said.

Ye Tianfeng said "no need", he went to the courtyard for a while, and saw Yan Yu and Gao Zhuang still looking at the field potato.

There is no field potato in the Yan's manor, as if Shicheng is not the hometown of field potato, Ye Tianfeng remembered that he had never seen field potato in Mu County.

It is natural for Yan Yu to be attracted to this beautiful plant all of a sudden.

As soon as he arrived in the courtyard, his eyes met the vines of the field potato. Ye Tianfeng had no time to speak. Suddenly, he became "Spartan" again. As a round of purple discs flashed from his mind again, the story about the field potato Everything immediately flooded into his head like a tide——
