"Daughter of the common people, please see His Royal Highness the Thousand Years Old."
When they saw Li Chen, Liu Sichun and others immediately put down what they were doing and came over to pay their respects.
After looking at a young man behind Liu Sichun who looked respectful and excited, with his head lowered and not daring to look at him, Li Chen said, "Everyone is exempt from the courtesy."
"Your Highness, this is Minnu's second brother Liu Sida. This trip to Zhejiang and Fujian to buy sweet potato seedlings is all thanks to his hard work along the way."
Under the introduction of Liu Sichun, Liu Sida came to Li Chen, bowed respectfully, and said excitedly: "Liu Sida, a common man, has met His Highness the Crown Prince. His Royal Highness is a thousand years old, a thousand years old, a thousand years old."
"No gift."
Li Chen glanced at Liu Sichun thoughtfully and said, "How many seedlings have been purchased this time?"
Liu Sida hurriedly replied: "There are more than 400 seedlings in total. Excluding those lost along the way, there are still more than 380 surviving seedlings. Moreover, the grassroots have also invited farmers with planting experience from the local area to come in person.
sowing."
Li Chen nodded with satisfaction and said: "Not bad."
Although it was just two words, it already made Liu Sida extremely excited.
"Your Highness, can it really be planted in this freezing cold weather?" Liu Sichun asked.
Li Chen smiled and said: "Of course it is possible, otherwise I would ask you to prepare such things."
With that said, Li Chen brought Su Jinpa to the edge of the field.
Although it has been cleaned up, the snowy and muddy ground and being on the edge of a field are naturally nowhere near clean.
Within a few moments, Li Chen's boots and trouser legs were already stained with mud, and Su Jinpa beside him was not much better.
But neither of them cared about these details.
Su Jinpa looked at the almost completed greenhouse on the field with curiosity and asked, "Your Highness, what does this mean?"
"This thing, I named it the shed."
Li Chen pointed to the newly built frame on the field and said: "Tender, soft but tough bamboo strips are used as the skeleton, which are tightly connected to each other, and then covered with glass and bronze mirrors that are polished by hand until they are transparent."
"In this way, it not only blocks sunlight, but also isolates the internal and external air temperatures, providing a good and suitable environmental temperature for the plants inside."
"Therefore, as long as you take proper care of it, eating watermelon in winter is no longer impossible."
Su Jinpa next to him felt more and more miraculous the more he listened.
Not only her, but also Li Keshou, Liu Sichun and others who were in charge of the construction, no one knew the true purpose of this thing.
Now that Li Chen explained it, everyone found it incredible.
Everyone knows that watermelon is a summer crop and requires hot weather to grow. It is impossible to eat watermelon in the middle of winter.
But this thing that His Highness the Prince has made can actually grow vegetables and fruits against the seasons. Is there such a magical thing?
Originally, the best material for making a greenhouse was plastic film, but in this era, it was impossible to produce plastic, and Li Chen was not a chemical engineer, so after thinking about it, he could only use bronze mirrors and polish them manually, although it was time-consuming and labor-intensive.
It cost a lot of money, but fortunately he was only temporarily cultivating a test field, so it didn't cost much.
Li Chen came to the greenhouse, and everyone followed him. He felt a little stuffy inside, but he could clearly feel that it was much warmer inside than outside.
Taking out a handful of seedlings, Li Chen turned to Su Jinpa and said: "This thing is called sweet potato, and because it is from foreign countries, it is also called sweet potato. It weighs tens of stones per acre, and is twenty times more valuable than grain. It is moist and edible, or
Boiled or ground into powder, it can be eaten raw like kudzu, cooked like honey, and tastes like water chestnuts."
"It is originally an annual, but if fertilized and cared for properly, the harvest period can be shortened to half a year. In addition, it is extremely adaptable and can be planted in most places in China. Jinpa, you said that if this plant is promoted on a large scale, but
