Gu Yunji planted a small amount of potatoes in her back garden so that she could observe them at any time, and the remaining more than 100 catties of potato seeds were entrusted to Zhang Cuiying, allowing her to sow seeds on her family's dry field, and taught the corresponding sowing methods and precautions.

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

At the beginning, there were about 15 or 6 catties of potato seeds, and now the potatoes harvested are almost 80 catties, and it took only more than two months to harvest one kind of potatoes, and the potatoes planted have increased by five or six times.

Although he heard Gu Yunji say that potatoes were highly productive in the morning, when he saw the results with his own eyes, Xu Shuhua still had some hard time: "Fifteen or sixteen catties have become more than eighty catties, and only such a small piece of land is used." As you said, it costs a total of 300 catties of artichoke to plant an acre of land, and it will be more than 1,000 catties when harvested. ”

"In this way, it only takes one acre of land and two or three months to grow enough food for a family to need for a year.

Gu Yunji smiled: "If it weren't for that, I wouldn't be so proactive in looking for artichokes." Moreover, there is more than one high-yield crop, as well as sweet potatoes, corn, etc., and these crops together are the real changes in food production. But those crops don't know where they are, and we can't chew them if we are greedy, so we just need to do a good job of potato planting now. ”

These potatoes have not been selected and bred, and their shape is very irregular, and they are generally small, and they are not in good condition. Although the current output is far less than that of the previous life, just by virtue of the yield of 1,000 catties per mu, it can be completely promoted, and Gu Yunji is already very satisfied.

Now that Xu Shuhua already knows Gu Yunji's origin, there is no need for him to hide it in front of her, and he said without hesitation: "It takes a long time for crop promotion to be promoted, and in the history of my previous life, it took two or three hundred years for high-yield crops such as artichokes to be widely planted across the country, and triggered an explosive growth in population. ”

"At the moment, even if I consciously encourage promotion, it takes time to plant and select seeds, and it will be very good to see obvious results in the whole Xuzhou capital in the next few years."

Xu Shuhua naturally understood this truth, nodded and said: "It's already very good that you can do this in his position." You said before that if you follow the natural development of history, it will take at least a few decades for artichoke to be introduced on a large scale, and such a high-yield crop can be planted a year earlier to reduce the starvation of a group of people, which is a matter that will benefit thousands of generations. ”

"My lord! My lord! ”

As he was talking, Chen Peishi ran all the way over excitedly, talking incoherently excitedly, and gesturing chaotically in his hand: "Zhang Cuiying's side has already harvested, there are a lot of artichokes!" Many, many, many! ”

Seeing this, Gu Yunji and Xu Shuhua looked at each other and smiled: "Then I'll take a look?" ”

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

Coming to the fifty acres of Zhang's family in Rongyin Mountain, Zhang Cuiying was sitting on the ground, shocked and looked at the potatoes all over the ground in a daze.

She is a person who has suffered from hunger, and has struggled on the line of life and death, and knows the preciousness of food. When Gu Yunji entrusted her to plant potatoes, she didn't have any practical concept of this, she only knew that she had to do a good job of the things that Gu Yunji handed over to her, but she didn't expect that in just two or three months, more than a hundred catties of potatoes would be planted.

Zhang Cuiying is an authentic farmer, and people like them have an attachment to food and land that is unimaginable for the rich and wealthy, and she doesn't need Gu Yunji to explain the long-term significance of potato cultivation from a lofty position, she can also understand what this means - to let more people have enough to eat.

Eating well, a wish that sounds as simple and simple as it sounds, is a goal that our ancestors have worked hard for thousands of years to achieve. It is easy for a person to have enough to eat, but the hard thing is to make everyone have enough to eat.

Even in the previous life, it was only with various science and technology that grain production has been greatly developed, and after careful calculation, modern people have only eaten enough food for decades, and their hungry stomachs have always been very close to ordinary people.

Today, there is such a crop that can feed millions of people, save millions from starvation, and may not allow them to live a good life with fish and meat, but as long as they do not starve, it is the greatest merit.

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

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

Seeing Zhang Cuiying's dazed face, Gu Yunji smiled helplessly, so she had to ask someone to weigh all the potatoes she had received with the scales she had brought with her.

After a short time, after the weighing was completed, more than 150 catties of artichoke seeds were planted, and a total of more than 980 catties of artichoke seeds were planted, and the yield rate was higher than that of Gu Yunji's home plant. Perhaps Zhang Cuiying's field is located in the middle of the mountain, with good drainage and air permeability, so the yield is relatively high.

Hearing this number, Zhang Cuiying was incredulous for a while, and her voice trembled: "More than 980 catties, almost 1,000 catties, this only uses half an acre of land, more than 100 catties of seeds, if there are enough seeds to plant 50 acres of land, wouldn't my family be able to plant 10 in a year...... 100,000 catties? ”

Gu Yunji smiled: "More than that." Artichoke can be sown in spring and autumn, and at least two crops can be planted in a year, so it is 200,000 catties. ”

"200,000 jin ......" Zhang Cuiying's legs were weak, and she almost collapsed to the ground again.

Gu Yunji was afraid that her ability to bear it would be too poor, so she fainted accidentally, and hurriedly said: "But don't be happy too early, this is just an ideal situation, after all, we don't have enough seeds." If you only rely on the existing potatoes to sow seeds, it will take at least one or two years to have 200,000 catties, and if the seeds are not screened, the yield will only be lower the more you plant. ”

Crops should be cultivated to be the best of the best, just like rice, which has evolved over thousands of years of selection. Gu Yunji did not have the science and technology of breeding in later generations, so he could only choose a stupid method - that is, to pick out the good quality and large size of this batch of potatoes and keep them as seeds for the next time.

There were not too many potatoes available, and Gu Yunji did not have enough quantities for strict screening, so in the end, he only picked out about three hundred catties of seeds and asked Zhang Cuiying to put them in the cellar for preservation. The rest is distributed to everyone and given to them to take home to try or plant, or to try it out for everyone.

If you want to expand potatoes in large quantities in a short time, you still have to buy them from the Americas, so Gu Yunji called Fan Li and discussed the follow-up purchase with him.
