Chapter 657 The Doubts of the Space Spirit
Ji Wushuang made up her mind and began to rummage in the space for the things she brought from the end of the world.

She remembered that although her life was not very good in the last days, sometimes when she saw some seeds when she went to the store, she would stuff them all into the space for later use. She didn't know if these seeds were still there. Cleared out by her.

After searching for a long time, I only found a few catties of sweet potatoes and a shriveled tomato.

As for rice and corn, there is not a single grain.

Space Spirit looked at the crops from the end of the world that Ji Wushuang found, and asked curiously: "Master, I'm actually very curious, why don't we grow corn?"

The space is that the land cannot grow rice, but corn has no effect!
It was puzzled and said: "I heard that corn takes more than 100 days to mature, and sweet potatoes take about 1000 days to mature. There is no difference in time between the two. As for the yield, I heard that the yield of corn per mu is more than [-] catties, while the yield of sweet potatoes is about [-] days. It is several times that of corn, but corn is much more hungry than sweet potatoes!"

Speaking of this, it still didn't forget to add, "And I also heard that you can't eat too much sweet potatoes, too much will cause heartburn and make you feel uncomfortable."

Ji Wushuang fiddled with the small shriveled tomatoes in his palm, and raised his eyebrows, "Because this is ancient times, many of the modern corn with an yield of one or two thousand catties per mu are excellent varieties that have been carefully bred by scientists. How can the original varieties of corn in Zhaoguo compare with them? It would be good if the yield per mu can reach several hundred catties."

She glanced at the pile of sweet potatoes she found, and said, "In the absence of good varieties of corn seeds, it is natural to give priority to sweet potatoes. Look at the sweet potatoes in my space, they are all high-yield. Although it’s only a few catties at the moment, as long as Qin Yufeng’s supernatural ability is passable, it’s more than enough for us to use these few catties of sweet potatoes to produce hundreds of catties for seedlings to grow seedlings.”

The space spirit let out a sigh, looking at the pile of sweet potatoes, it was a pity and said: "Master, you should have put a few more bags of corn in the space, so that we can let the people of Dazhao country eat high-yield corn. .”

Ji Wushuang didn't feel sorry at all, and said with a smile: "Don't feel sorry, many corns in modern times are hybrid/cross varieties, and usually no one will keep this kind of hybrid/cross varieties, because the corn seeds that they saved are planted. The second generation will reduce the yield, which is useless at all. Self-breds can save their own seeds, and the second-generation corn can mostly produce high yields, but how do we know whether those corns are self-bred or hybrid/hybrid varieties? Maybe even if I harvested a few The bags of corn, in the end, are all hybrids, too, no good."

Space Spirit stared blankly at Ji Wushuang, and asked worriedly, "Then the sweet potatoes we brought from the end of the world are also hybrid varieties? Will they also reduce production?"

Ji Wushuang shook his head, "Sweet potatoes are propagated vegetatively, that is, from cuttings. The second generation grown from their own seeds has very little impact, almost negligible."

Although Space Spirit doesn't know much about these high-tech terms, it still shook its head with a look of sudden realization, "No wonder those farmers spend money every year to buy new rice seeds and corn seeds on the market, but sweet potatoes, potatoes and others Soybeans are crops that they have planted themselves."

Ji Wushuang didn't know if she was right or not, she just vaguely saw someone talking in the penguin group.
