"I just remembered that I still have some of these two things." Su Li said with a smile on his face. Li Er was stunned, and quickly asked: "Where is it? Get it quickly." Su Li pouted her lips, motioning Li Er to look back. "It's in the pot behind you." Su Li panted heavily, which made Li Er uncomfortable. However, at this time, he didn't care about other things, and turned his head and looked back. Under the night, with the help of the light, Li Er could see the emerald green branches, leaves and vines at a glance. The potatoes don't grow very high, and a bunch of leaves are randomly scattered above the flowerpot, swaying with the wind. The vines of sweet potatoes are whitish, even if they are planted in pots, they look a bit sparse. These two things look ordinary, and there seems to be little difference from the common green leaves on the roadside.
But in Li Er's eyes, these flower pots in front of him are simply the most precious things in the world. Li Er couldn't help standing up, walked to the flower pot, lowered his head, and looked at the things inside with a fascinated expression. The hands that had grabbed French fries and sweet potatoes were casually wiped on the expensive robes. Afterwards, Li Er raised his hand and gently stroked those few leaves. Seeing Li Er's appearance, Su Li was also a little emotional. Not to mention other things, Li Er, who cherishes food so much, obviously has a real heart for the suffering of the people. Just for this point, Li Er can be called a good emperor. At this moment, Li Er's heart was full of ecstasy. In the short quarter of an hour just now, his mood can be said to have been on a roller coaster. Li Er was as happy as Yunxiao when he suddenly heard that there was a thousand jins of divine food per mu. But then he learned that the precious grains had been eaten. Even Ji Er couldn't bear the great sense of loss. Just when he was about to mobilize the power of the whole country to travel across the ocean to bring these two things back, Su Li suddenly said that there were still some grain seeds. Su Li gasped for a few breaths, almost causing Li Er, the father-in-law, to have a heart attack. But Li Er didn't blame Su Li at all! "These two things have been planted for a long time, counting the time, they are almost ripe, you can see for yourself. Su Li's voice sounded from behind, and Li Er was overjoyed when he heard that. Without hesitation, he reached into the flower pot and picked up the soil inside. Seeing his cautious appearance to avoid touching the roots, Su Li couldn't help being a little amused. After all, he is his father-in-law, so how can he work there and sit on the sidelines?
Besides, although the flower pot is not big, the soil inside is quite solid because it grows grain. Just rely on Li Er's two hands to pull slowly, when will this be done? He stood up and walked to Li Er's side. Reach out and grab the part of the rhizome exposed on the soil surface, and apply a little force. Then, a large lump of potatoes was pulled out of the soil by Su Li. "Why so rude!" Li Er gave Su Li a dissatisfied look. Immediately afterwards, his eyes were attracted by the things in Su Li's hands. Li Er simply squatted on the ground, staring straight at the pile of yellow fruits of different sizes under the rhizome. "Is this a potato?" He gently picked off the smallest potato, stroked the dirt off it with his hands, and tapped it lightly with his nails. The moist touch of his fingers immediately filled Li Er with an unprecedented sense of satisfaction. "This is a potato, and its fruit is also a grain seed. You can pick it off and roughly estimate its weight.™ Su Li knew what Li Er was most concerned about, so she kindly suggested. Li Er immediately followed suit and called his eldest grandson over. As a result, the couple with the most distinguished status in the entire Tang Dynasty picked potatoes just like ordinary old farmers. The eldest grandson dug out a basket out of nowhere, dropped it in his hand, and held a ladle of water in his other hand. Every time Li Er picked a potato, the eldest grandson would wash it clean and put his heart in the basket. After a while, the two of them finished their work. Li Er looked at his eldest grandson and asked, "What is the weight?" Even with Su Li's words as a basis, Li Er was still a little uneasy at this moment, and always wanted to confirm it by himself. Empress Changsun weighed the basket, and a look of disbelief flashed in her eyes. "It weighs more than ten catties? I don't think you are allowed to try it yourself." Li Er immediately became excited. He took the basket and weighed it up and down. This weight, ten catties can't hold it... A mere two-palm-wide flower pot can grow ten catties of grain. In terms of yield per mu, hey... Thinking of this, Li Er couldn't help but gasp. 0…ask for flowers…… He immediately figured out that the yield of potatoes per mu may exceed the one thousand catties that Su Li said! "Look at the sweet potato again!" Li Er said impatiently.
The couple went to the flower pot with sweet potatoes again, this time without Su Li's help. Empress Changsun found a small shovel from the side, and then Li Er emptied the soil in the flower pot with three shovels. Soon, the weight of sweet potatoes was also calculated. Sweet potatoes are big and don't produce as much fruit as dry beans. But overall, the weight is not lighter than potatoes, or even worse. seeing is believing! The big stone in his heart fell to the ground, and in turn, Li Er was surrounded by boundless excitement. Li Er closed his eyes, imagining that one day, potatoes and sweet potatoes would spread to the world. At that time, he can tell the world that from now on, under the rule of the Tang Dynasty, no one will starve to death! With such achievements, even if Li Er fails to achieve anything else, it will not prevent him from leaving his name in history and becoming the eternal emperor praised by future generations! "I want to plant these two kinds of grains in all the fields of Datang..." Li Er turned his head to look at Su Li, and said slowly. Hearing this, Su Li was taken aback and quickly tried to persuade her. "Although the yield of potatoes and sweet potatoes is high, the storage conditions are harsh. The trouble of storage means that the circulation is inconvenient. Large-scale promotion is unnecessary!" Compared with other staple foods, potatoes and sweet potatoes are really not a good thing to preserve. In granaries all over the country, there are many old grains that have been stored for three to five years. But can potatoes and sweet potatoes last that long? The storage conditions of potatoes have relatively strict requirements on temperature. If the temperature is slightly higher, if it is left for a long time, it will turn purple and germinate. Potatoes with sprouts are poisonous. Compared with potatoes, sweet potatoes are relatively easy to store, but under normal circumstances, they will be stored for a month if they are full. If you get a sweet potato cellar, you can greatly extend the storage time, but it is difficult to exceed one year. After a long time, it will also germinate and become moldy, and the heart will become stiff. Li Er's current mentality is like most poor people getting rich. Simply put, happiness comes so suddenly that it goes from one extreme to another. But in any case, these two things are really not like this!.
