At this time, the grain output of the Qin Empire was only an average of two shi of grain per mu. Calculating this, it did not exceed 300 kilograms of grain.
It can be said to be quite shabby and pitiful.
But there is no way. Before chemical fertilizers and irrigation technology made great progress, this kind of output was basically the limit.
Throughout the feudal period, the grain output per acre of land basically did not fluctuate much. It was all cultivated by manpower, and the seeds were all good and bad. The harvest was basically dependent on God's blessing.
"This product is called sweet potato, also known as sweet potato. It can be used as a staple food instead of grain. It is very useful. It can be washed and peeled directly and eaten raw. It can also be cooked and eaten. It can also be dried for a long time. If this is not possible, grind it.
After being turned into powder, it can be transformed and processed into a variety of foods."
Li Chen took the small cloth bag. It was a small cloth bag, but it was the key to the Qin Empire's improvement of people's lives.
"The most important thing is that once this thing is planted and taken care of properly, there will be as few as three or four fruits on such a plant, as many as six or seven, and the yield per acre of land can easily exceed 500 kilograms, which is almost as much as barley and corn.
More than double that.”
Li Chen's eyes flashed with excitement, and he said to Liu Sichun: "Now, do you know why I am so anxious and excited?"
Liu Sichun's pretty face was full of shock, and she exclaimed: "Seriously!?"
As a businessman, Liu Sichun's sense of smell is far more sensitive than ordinary people.
She knew very well that if what Li Chen said was true, then this thing could almost start a revolution.
The opportunity contained in it made her breathe quickly involuntarily.
But then, Liu Sichun realized something was wrong.
"If it's really so good, why don't people in Zhejiang and Fujian grow it even though they've been exposed to it for a long time?"
Li Chen waved his hands and said: "This plant likes warmth and is afraid of cold but is not cold-tolerant. Except for a few areas in Zhejiang and Fujian, there are many mountains and few plains. The wind is too strong and the environment is wet and cold, so it is not suitable for its growth. If it is to be planted in Zhejiang and Fujian, at least
It takes more than three generations of cultivation and careful selection of seedlings.”
"But north of the Yellow River is its natural hotbed, and it can certainly be planted on a large scale."
Liu Sichun suppressed her beating heart. She stared at the inconspicuous sweet potato on the cloth bag and said, "This thing is not common. If His Highness needs it, the daughter of the people will immediately have all the sweet potatoes that can be collected.
For His Highness’s use.”
Li Chen said happily: "Okay, we will start collecting immediately. Later, I will set aside a fertile field in the Huangjia Forest Farm and find someone to plant it. The harvest will be available within a few months. By then, something big will happen."
It’s done!”
Liu Sichun said in confusion: "Your Highness, didn't you say that it likes warmth and is afraid of cold? How can you grow it now that it's cold and the ground is freezing?"
Li Chen chuckled lightly and said: "There is a technology called a greenhouse, which allows you to grow spring and summer fruits in autumn and winter. It is amazing. When I promote it, it will not be unusual to eat watermelon during the cold winter months.
Already."
"Is there such a magical thing in the world?"
Liu Sichun's eyes flickered, and she asked curiously: "How did Your Highness know this?"
"It's just what I see in the book."
Li Chen waved his hands and casually found an excuse to dismiss it.
"You have made a contribution in this matter, what reward do you want?"
Liu Sichun pursed his lips and smiled, and said happily: "I am honored to be able to do something for His Highness, and I do not dare to ask for reward."
