In the rumbling sound, the two trains ran for three days and brought a large amount of supplies to Chang 'an.
The ship with mooncakes and grapes sailed to Dengzhou and Lai Zhou in Henan Province. In a few days, it will be August 15th. The navy in Chang 'an has to send the supplies to their families in advance.
At this moment, they had already received a letter from the Haizhou Courier Station, including the Yulin Flying Cavalry who were responsible for setting off the fireworks.
Li Yi planted the potatoes and sweet potatoes he brought back in order to prevent them from rotting. When the weather turned cold, he would put a greenhouse on them.
He didn't plant the potatoes in the current season, so he planted the potatoes in the greenhouse one month later.
Because there were a lot of potatoes in the autumn harvest, they could be preserved until spring.
When the potatoes in the greenhouse were ripe, the cheap potatoes were not eaten up. Few people were willing to spend a lot of money to buy new potatoes in the greenhouse.
From mid-February to March, the potatoes in the greenhouse would be harvested.
At this time, many potatoes began to sprout or were black-hearted, so the new potatoes in the greenhouse would be accepted.
No one in the Tang dynasty competed with the Li Family Zhuangzi in the potato sales. They could plant the potatoes at any time.
If they planted the potatoes now, they could be harvested before the twelfth lunar month.
They kept some to eat and kept the temperature suitable. The potatoes they harvested before could be planted again.
When this batch of potatoes could be planted, it would be a little later. They wouldn't plant other crops and would continue to put up the greenhouse.
It was easy to make the potatoes and sweet potatoes sprout.
For the seeds, they were willing to put up the greenhouse in all four seasons.
"This winter, we can eat roasted potatoes and sweet potatoes as much as we want."
Li Yi held a big potato in his hand and was about to fry it for lunch.
The potatoes he brought back could be harvested. They were just planted and brought back by the navy, so they could be planted.
Now, he just needed to taste them and then give the potatoes an artificial environment to let the new potatoes pass the dormant period as soon as possible, sprout, and then plant them again.
Later on, he would have to give them to the Sinongsi. It was quite troublesome for them to organize people.
Almost all the people in the Sinongsi were there. Those who went to look for seeds were still there.
The Sinongsi had the most people now, both internal and external, and the imperial court had allocated a lot of funds.
They did produce results, which was different from Li Yi's at the beginning.
In the beginning, it wasn't that his country didn't pay attention to it. It was just that they didn't have enough money. They didn't have enough funds and were short on manpower. They had to rely on luck to find a crop.
Under Li Yi's request, the Tang dynasty's Agriculture Temple mobilized tens of thousands of people, and the local government also had to cooperate.
The Minister of Agriculture, Shaoqing, and the others personally ran to the field to dig the potatoes.
They took off their official robes and wore cropped trousers and waistcoats. Each and every one of their muscles looked quite beautiful, indicating that they were indeed people who worked.
A group of people collected the potatoes, followed by another group of people. They picked up the leftover potatoes, regardless of their size, and put them into baskets. Afterwards, they had to be weighed.
First, they harvested one mu of land and carried baskets of potatoes over.
Li Longji and the others watched and waited.
Actually, there was no need to look any further. He already knew that the harvest was higher than anything else.
Each basket weighed seventy to eighty catties. Fifteen baskets were filled, and there were still some left.
With no one holding an umbrella, everyone was sweating profusely. Beside them, there was someone passing them a cool mountain spring water. Only after taking a sip did they feel better.
"That's all? I live in a fertile land and take care of it carefully. You don't give me any face. "
Li Yi mumbled and complained, blaming the potatoes for not growing well.
The people around him were speechless.
"Xiao Yi, that's enough. We know that the potatoes you brought back have a high yield per mu. Why do you have to do this? "
Bi Goo was so angry that he scolded Li Yi.
"Watermelons are a lot in one mu of land. How long will it take for you to be hungry after eating watermelons?" Li Yi calculated another matter.
"Potatoes are the same as habits? I eat fried potato slices and shredded potatoes, not watermelons. "
Li Dan knew what Li Yi meant. He had eaten potatoes before and found that they could fill his hunger.
"According to the amount of water in them, the proportion of water in potatoes is more than three times that of rice and wheat.
Rice and wheat in good fields can yield about three dan per mu.
If we calculate the water content alone, the yield of ten dan per mu of potatoes can be considered equal.
Of course, there are other things in potatoes that rice and wheat flour can't compare to. "
Li Yi disliked the low yield, but he approved of potatoes in other aspects.
"Doctor Li, I'll give you three dan of rice or millet, or ten dan of potatoes. Which one will you choose? You can only eat one of the three. "
Liu Youqiu was the most straightforward. Don't talk about other things, what do you want?
"Of course, potatoes. There are other things in potatoes that are good for the body. I'm not allowed to eat other vegetables, so I can only rely on potatoes to supplement."
Li Yi was also straightforward. Potatoes. Although he always treated potatoes as vegetables and snacks, it didn't mean that he didn't understand.
"Okay!" Liu Youqiu was satisfied with the answer, which meant that potatoes were good.
While they were talking, all the potatoes were taken out, placed in a basket, weighed, and finally peeled.
After Qin Shouyi finished calculating the data, he stood there and didn't make a sound.
"How much?" Song Jing asked in a deep voice. I'm waiting for you. You're in a daze.
"One, one thousand eight hundred, eight hundred and forty, nine catties." Qin Shou stuttered.
"Weigh it two more times." Yao Chong urged.
According to this number, when converted to stones, it was more than fifteen.
Didn't Li Yi say that there was a lot of water? More than three times the amount of water was deducted. There were also five dan of dry things, which was 60% more than the three dan.
Everyone weighed it again. After weighing it twice in a row, the difference between the numbers was less than five jin.
"See, I said it was less. According to my idea, with this kind of land and care, it should be at least forty-five or sixty-six dan."
Li Yi calculated according to the best potato seeds in his time, which had a yield of eight thousand jin per mu.
It was impossible for the common people to use good land for planting, and it was impossible for them to take care of it.
It was normal for the yield to drop to ten dan per mu. Compared to the rice and wheat in good land, it was only a little better.
"Should we plant it or not?" Su Yi found that he was particularly annoyed with Li Yi. Can't you say something to make everyone happy? What forty-five or sixty-six dan?
"If we plant it, it can be a staple food or a non-staple food. The yield is low, but we can think of ways to increase it.
In terms of management, it's easier than rice and wheat.
It's not realistic to plant rice in the grassland. Wheat is also afraid of birds. Plant potatoes and wait for them to grow, then bury them in the ground. "
Li Yi nodded. He did not want to pour cold water on them. According to his calculation, the yield of rice was even lower now.
"What should we plant after the potatoes are harvested?" Bi Goo looked at the empty ground and knew that Li Family Zhuangzi's land was fertile.
"Planting vegetables. We can still get a season. Actually, potatoes can be planted twice a year in some places. For example, in Henan Province, we are planting indica rice now. "
Li Yi calculated the time. Chang 'an was not suitable for planting crops now.
Of course, he would not plant vegetables. He would plant other things and then plant them in the greenhouse.
"Gang Rou, what about the potatoes now?" Zhang Jiuling looked at the potatoes in the basket and wanted to know how to deal with them.
"Pick the big ones and leave them for us. We can eat the medium and small ones. The small potatoes can be pickled or boiled with more salt. When the potatoes are boiled, there will be a layer of salt frost on the outside, but it's not salty inside. Potatoes with salt frost. "
Li Yi smacked his lips as he spoke. If he wanted to eat, he would cook it now and eat it as a snack.
"Ok, let's eat potatoes at noon." Li Longji, who had eaten potatoes before, was also hungry. This time, he could eat freely without any heartache.
