Back to the era with space materials

As soon as Jiang Yue's voice fell, the captain who had been silent in front asked Si Ningning: "Where did you see that three seasons of rice can be grown in the south?"

Luo Daqing is a true southerner. He has been farming all his life. The common people are exhausted from farming every year. He has never heard of a place that can grow the third crop of rice in a hurry.

Luo Daqing didn't mean any harm, he was just curious, but to Jiang Yue's ears, this sentence sounded so sweet, it was like Luo Daqing slapping Si Ningning in the face in public.

Jiang Yue was secretly happy for a while, but before she could step forward to laugh, Si Ningning spoke again:

"I used to like reading books, and this is what it says in the book: 'The Yangtze River Basin is located in the subtropical zone, and rice can be harvested twice a year; north of the Yangtze River, with high latitude, rice can only be harvested once a year. Hainan Island is located in the tropics, with sufficient heat, so

Rice production can produce three crops a year.'"

Luo Daqing nodded and said "hmm". In fact, he had never heard of Hainan Island, but Si Ningning's previous two sentences about south and north of the Yangtze River were pretty good.

Luo Daqing is not sure whether there is really such a place called "Hainan Island" that can grow three-crop rice, but at least one thing is certain.

That means Si Ningning really has a certain understanding of this aspect.

Jiang Yue thought that this matter would develop further, but she didn't expect that after Luo Daqing said "hmm", there would be nothing more to say.

Jiang Yue was unwilling to not see Si Ningning embarrassed, and sneered and deliberately stepped forward to sarcastically say: "Have you been to Hainan Island? You are so sure that what you said is clear and logical. Who knows whether what you said is true or false."

Everyone just walked along the road and chatted when they felt bored. Not many people cared about whether Hainan Island can grow three-season rice.

But when Jiang Yue said these words, the atmosphere suddenly cooled down. Everyone looked at me and I looked at you, feeling a little embarrassed.

"In the summer of 1970, Teacher Yuan conducted research on Hainan Island and succeeded in planting the third season of rice. In the same year, the results were published in major city dailies." Si Ningning looked at Jiang Yue, speechless, silent, and said helplessly:

"This is what happened two years ago. Even if you don't read books or newspapers, you should have heard about it."

Although in later generations, the cultivation of three-crop rice in Hainan was not promoted on a large scale because it required huge manpower and economic support, but in this era when most people do not have enough to eat, this achievement is also a milestone of this era and is regarded as

Most people keep it in mind.

Jiang Yue opened her mouth.

Don't read books? Don't read newspapers. This is driving her to the core.

Song Shuhan, a male educated youth, said: "It seems that there is such a thing. I was in the first grade of junior high school at that time, and the school teacher even mentioned this matter, but we have never farmed..."

Song Shuhan was the fairest among the male educated youths. He was elegant and elegant, with round-rimmed glasses on the bridge of his nose. He had a bit of the bookish air of a literati from the Republic of China.

As he talked, he chuckled sheepishly: "Just, I didn't really listen very carefully."

Other educated youths followed suit and joked, "Haha, you have to remember this time, it's not the teacher who teaches you now, it's the Si educated youth!"

Song Shuhan glanced at Si Ningning, touched the back of his head and nodded sheepishly.

Si Ningning was not someone who couldn't take a joke, and everyone was joking around in a good mood, so she didn't say much, she raised her fingers, rubbed her knuckles against her nose, and laughed with everyone.

Jiang Yue snorted coldly, her face extremely expressionless. It would be superfluous to say anything else at this time, so she simply shut up and kept silent.
