I trade in both worlds

Xu Ziqing couldn't help but sigh: "Alas~"

Xu Xu asked curiously, "Is it very low? What is the yield per mu in your area?"

"We." Xu Ziqing looked up at Xu Xu and said, "Our output is more than ten times that of yours."

"How much? Ten times?" Xu Xu was so surprised that his voice became sharp.

Xu Ziqing nodded: "Yes, our wheat yield per mu exceeds 10 dan, and our rice yield per mu is 24 dan."

"Ten...ten...ten stones of wheat?" Xu Xu asked in disbelief.

Xu Ziqing looked at Xu Xu and said, "Don't disbelieve me, your yield per mu is really too low, alas~"

Xu Xu pursed his lips, still finding it hard to believe. The yield from one acre of land there might be higher than the yield from ten acres of land. If their yield was that high, then it would basically solve everyone's food and clothing problems.

Their yield is so high, can the seeds be used for planting? Thinking of this, Xu Xu asked directly: "Can your seeds be planted here?"

"Ah?" Xu Ziqing was stunned. He had never understood this before. "I don't know. I seem to have heard somewhere that the seeds can only be planted for one season and cannot be saved."

After thinking for a while, Xu Ziqing continued, "Wait for me to go back and check. If the latest varieties cannot be saved for seeds, then buy the old ones that can be saved for seeds. No matter what, the yield will be higher than what you have now, right?"

Xu Xu nodded: "Yes, please help me check it. How do I pay?"

"Well, it's a small matter." Xu Ziqing said, "Gold and silver are also hard currencies in our place, but the gold and silver content in yours is not as high as ours. If you bring yours over there to use here, there might be trouble. There's no problem exchanging yours there, but you just can't afford the price."

"That's good." Xu Xu felt relieved when he heard that gold and silver could also be exchanged for money.

Xu Ziqing remembered that potatoes had not been mentioned yet, so he continued, "In fact, there are several kinds of foreign food that have higher yields. One is the potato we eat in the morning. It can be used as a staple food or as a vegetable. We grow potatoes over there and the yield per mu is more than 100%. Do you want to try growing potatoes first?"

“?” Xu Xu was stunned. There was actually such a high yield of grain?

Xu Ziqing nodded: "You don't need fertile soil to grow potatoes. Sandy soil is most suitable for planting. The most important thing is that the growth cycle is short. The shortest one can be harvested in about 60 days."

"Two months?" Xu Xu was already numb with shock. She felt that nothing could stir up any waves in her heart anymore.

"Yes, it's short-term." Xu Ziqing searched the Internet and continued, "It says that early-maturing varieties of potatoes take about 60 to 70 days from germination to harvest, mid-maturing varieties take 85 to 120 days, and late-maturing varieties take more than 120 days."

Xu Xu said: "Even if it is 120 days, it is more than 4 months, which is much shorter than the cycle of other grains."

Xu Ziqing: "Yes, do you want to try planting it?"

Of course, Xu Xu looked at her expectantly and asked, "Can we grow it here?"

Xu Ziqing said affirmatively: "Of course, of course. Many potatoes on the market now are continuously improved varieties, and their main features are resistance to diseases, waterlogging, drought, and storage. The environment here is much better than today, so it is definitely possible to grow them."

"Drought and flood resistant?" Xu Xu asked puzzledly, "This means that the harvest can be guaranteed regardless of drought or flood, and there is no fear of any natural disasters."

Xu Ziqing had just searched this passage in the morning, and had not expected it to be so contradictory. He was stunned for a moment. Even if he did not understand, he knew that potatoes could not be immune to any natural disasters: "That shouldn't be the case. Soaking in water will definitely not work. It's too dry. Not watering it at all will definitely not work. It will die."

"Yeah, that's right." Xu Xu continued to ask, "When are potatoes usually planted?"

看了看手机上搜索出来的内容，徐梓青看着手机一字不落地念了出来：“春季种植在每年的3-4月份最合适，秋季种植在每年的9-10月份最合适，冬季种植可在每年的12-1月份左右最合适。”

"Can we grow three crops a year?" Xu Xu asked in surprise.

"Yes." Xu Ziqing knew the answer without even looking it up: "But it depends on the climate. The surface temperature needs to be 5-8 degrees when planting."

"Temperature? What temperature?" Xu Xu asked.

Why was she always asked to figure out such simple but difficult to understand questions? Xu Ziqing felt that she had spent more time thinking in the past half day than she did in the whole of last year.

Xu Ziqing waved his hand and said, "You won't understand this question even if I tell you. I'll give you a thermometer so you can experience it yourself. Let's get back to the topic of potato planting."

Seeing Xu Xu opening her mouth to speak, Xu Ziqing was afraid that she would keep asking what a thermometer was, so he interrupted her and said, "The weather in my hometown can only support two seasons. According to some time travel rules, the weather here should be similar to my hometown."

Xu Xu: "If we can plant two crops, one in March and one in September, then can I start planting after the autumn harvest?"

"Yes, yes..." Xu Ziqing nodded halfway before he remembered that the time he searched out should be the Western calendar, but the lunar calendar is used here, so the planting time cannot be calculated in this way.

Xu Ziqing quickly corrected himself and said, "No, the time I mentioned may be different from yours. You should be able to plant the first season after the spring, and plant the second season after the summer harvest."

When Xu Xu heard that they could start planting after the summer harvest, he became anxious and said quickly: "We just finished the summer harvest, so can we plant now?"

"Huh?" Xu Ziqing said excitedly, "It is indeed time to plant. How about we go back and buy some potato seeds?"

Xu Xu was excited to nod, but when he thought about the money he had to spend to buy seeds, and he didn't have the money, he looked at Xu Ziqing awkwardly and asked, "Sister Qing, can I exchange silver for money?"

Seeing her embarrassed expression, Xu Ziqing thought she had some difficulty. She smiled and said, "Oh, this thing is very cheap. It doesn't cost much. I can buy it for you."

Xu Xu refused, "No, I plan to plant three to five acres. Seeds are not cheap, not to mention this kind of high-yield seed. If you don't charge me, then I'd rather not have it."

Seeing her stubborn look, Xu Ziqing said helplessly: "This thing is really worthless, but forget about exchanging it for money. How about we find something to sell over there, and then you can return it to me?"

"That's fine." Xu Xu thought that after the potatoes were planted, he would find some better ones that were rare over there but not too expensive here and take them over there to have a look.
