Gu Yunji planted a small amount of potatoes in his backyard for observation at any time, and entrusted the remaining 100 catties of potato seeds to Zhang Cuiying, who asked her to sow seeds on her family's dry field, and taught the corresponding sowing methods and precautions. matter.

Two or three months later, the potatoes were ripe. While Gu Yunji sent someone to tell Zhang Cuiying to start harvesting, he personally dug out the potatoes planted in the back garden.

The potato seeds sown at the beginning weighed about [-] to [-] catties, but now the harvested potatoes are about [-] catties. It takes only two months to harvest one species, and the number of potatoes planted has increased by five or six times.

Although he had heard Gu Yunji say that potatoes were highly productive earlier in the morning, Xu Shuhua was still a little unbelievable when he saw the results with his own eyes: "Fifteen or six catties turned into more than 80 catties, and it only took such a small piece of land. As you said, planting full A total of 1000 catties of yams are needed for one mu of land, so there will be more than [-] catties when harvested."

"In this way, it only takes one mu of land and two or three months to grow enough food for a family for a year. If the cultivation can be popularized, wouldn't the people in the world really not have to go hungry anymore?"

Gu Yunji smiled and said: "If it weren't for this, I wouldn't be so proactive in looking for potatoes. Besides, there are more than one high-yield crops, such as sweet potatoes, corn, etc. The combination of these crops is what really brings food production. Change. But those crops don’t know where they are, and they can’t chew on more. Now we just need to do a good job of planting yams.”

These potatoes have not been selected and bred, their shape is very irregular, their size is generally small, and their quality is not good.Although the current production is still far inferior to that of the previous life, it can be widely spread just based on the yield per mu, Gu Yunji is already very satisfied.

Now that Xu Shuhua already knows Gu Yunji's origin, he doesn't need to hide it in front of her, and said without hesitation: "Crop promotion takes a long time. In the history of my previous life, it took two to three hundred years for high-yield crops such as artichoke It has been widely planted across the country and triggered an explosive growth in population."

"Even if I'm consciously encouraging the promotion, planting takes time, and seed selection also takes time. It would be great to see obvious results in the entire Syrian capital in the next few years."

Xu Shuhua naturally understood this truth, nodded and said: "It is very good that you can do this when you are in charge of politics. You said before that if the natural development of history is followed, it will take at least several decades before the large-scale spread of yams. , such a high-yield crop, planting a year earlier can save a lot of people from starvation, which will benefit generations to come, and it must be better if you do more, so you don’t have to be too demanding on yourself.”

"My lord! My lord!"

Just as he was talking, Chen Peishi ran over excitedly, incoherently speaking excitedly, gesticulating indiscriminately in his hand: "Zhang Cuiying's harvest has been completed, there are so many yams! So many, so many!"

Seeing this, Gu Yunji looked at Xu Shuhua and smiled: "Then I'll go and have a look?"

Xu Shuhua smiled and nodded lightly: "Okay, let's go."

Arriving at Zhang's [-]-acre land in Rongyin Mountain, Zhang Cuiying was sitting on the ground, stunned by the shock, staring at the potatoes all over the ground in a daze.

She is a person who has suffered from hunger, and has also struggled on the verge of life and death, so she knows the preciousness of food.When Gu Yunji entrusted her to grow potatoes, she had no practical idea about it. She only knew that she had to do well what Gu Yunji had entrusted to her. Unexpectedly, in just two or three months, more than 100 catties of potatoes were planted like this extra.

Zhang Cuiying came from an out-and-out peasant family. People like them have nostalgia for food and land that is unimaginable for the well-off and rich. She doesn't need Gu Yunji to elaborate on the long-term significance of potato planting, she can understand what it means—let More people are fed.

To have enough food, a wish that sounds extremely simple and simple, is a goal that our ancestors have worked hard for thousands of years but have not achieved.It is easy to feed one person, but it is difficult to feed everyone.

Even in the previous life, food production has been greatly developed by virtue of various science and technology. After careful calculation, modern people have only had enough food for decades, and the hungry stomach has never been very close to ordinary people. .

Now there is such a crop that can feed millions of people and prevent millions of people from starving to death. Maybe they still can't let them live a good life with fish and meat, but as long as they don't starve, they will be fine. It is the greatest merit.

Zhang Cuiying stroked the potatoes all over the floor, and couldn't help but burst into tears.Seeing Gu Yunji coming, she struggled to stand up, her legs were so weak that she could not walk steadily, and said in a crying voice: "My lord, there are so many... so many yams."

Gu Yunji couldn't laugh or cry: "Yes, there are a lot of yams, how many are there, have you weighed them?"

Seeing Zhang Cuiying's bewildered face, Gu Yunji smiled helplessly, so he had to ask someone to weigh all the yams they harvested with the scales they brought with them.

Not long after, the weighing was completed, and a total of more than 150 kilograms of yams were planted out of more than 980 kilograms of yam seeds, and the yield rate was higher than that of Gu Yunji's planting at home.Perhaps Zhang Cuiying's field is located halfway up the mountain, with good drainage and air permeability, so the yield is relatively high.

Hearing this number, Zhang Cuiying couldn't believe it for a while, her voice trembled: "More than 980 catties, which is almost a thousand catties, and it only takes half an acre of land and more than 100 catties of seeds. If there are enough seeds to put fifty If the mu of land is full, wouldn't my family be able to grow ten...one hundred thousand catties a year?"

Gu Yunji smiled and said: "Not only. Artichokes can be sown in spring and autumn, and at least two seasons can be planted in a year, so it is 20 catties."

"20 catties..." Zhang Cuiying's legs gave way, and she almost collapsed on the ground again.

Gu Yunji was afraid that her ability to bear it would be too poor, so she fainted by accident, and quickly said: "But don't be too happy, this is just an ideal situation. After all, we don't have enough seeds. If we only rely on the existing potatoes to sow seeds, at least one or two There are only 20 catties per year, and if the seeds are not screened, the more they are planted, the lower the yield will be."

Planting crops must be selected from the best, just like rice, which evolved into what it is today after thousands of years of selection.Gu Yunji didn't have the science and technology of breeding for later generations, so he could only choose a stupid method - to pick out the good-looking and big ones from this batch of potatoes, and save them as seeds for the next time.

There are not too many potatoes, and Gu Yunji didn't have enough for strict screening. In the end, only about [-] catties of seeds were picked out, and Zhang Cuiying put them in the cellar for safekeeping.The rest will be distributed to everyone, let them take it home and try it out, or plant it, in short, try it yourself.

If he wanted to grow potatoes in large quantities in a short period of time, he still had to buy them from America, so Gu Yunji called Fan Li and discussed with him about the subsequent purchases.
