"Yes, this is the thing!"

Li Chenxi is in shape.

At this time, the food output of the Great Qin Empire, but the average grain per acre of two stones per acre, which is counted, does not exceed 300 pounds of grain.

It can be said that it is quite shabby and pitiful.

But there is no way, before the fertilizer and irrigation technology have not achieved a lot of development, this output is basically the limit.

Throughout the feudal period, the grain output per acre of land basically did not have much floating changes. It depends on manpower to cultivate fields. The seeds are also different and bad. What is the harvest?

"This item is sweet potato, also known as sweet potato, which can replace food as the main grain, which works greatly. It can be washed and raw and eaten directly.

After becoming a powder, you can change into a variety of foods. "

Li Chen took this small cloth bag and a small cloth bag, but was the key to improving the lifeblood of the people's livelihood.

"The most important thing is that once this thing is planted and takes care properly, there will be less than three or four fruits under such a plant, as many as six or seven.

Doubles more. "

Li Chen's eyes flashed with excited light, and said to Liu Sichun: "Now, you know why the palace is so anxious?"

Liu Sichun's pretty face was full of shocking look, she exclaimed: "Truth !?"

As a businessman, Liu Sichun's sense of smell is far more sensitive than ordinary people.

She knew very well that if Li Chen said it was true, then this thing could almost set off a revolution.

The opportunity contained in it made her breathlessly breathe.

But immediately, Liu Sichun realized that it was wrong.

"If it is really so good, why does the people in Zhejiang and Fujian have long been in contact with its people, but they don't plant it?"

Li Chen waved his hand: "This thing is warm and afraid of cold and cold, Zhejiang and Fujian, unless a few areas, high mountains and plains, the wind is too large and the environment is cold and cold, it is not suitable for its growth.

It is necessary to carefully select seedlings through three generations. "

"But north of the Yellow River, it is its natural hotbed, which can inevitably plant it in a large area."

Liu Sichun held up the beating heart. She stared at the sweet potatoes that were not eye -catching on the cloth bag, and said, "This thing is not common. If the His Royal Highness needs, the daughter of the people immediately allows people to collect all the sweet potatoes that can be collected.

Use Royal Highness. ""

Li Chen was relieved: "Okay, start to collect immediately. The palace will later draw a fertile land in the Huangjialin Farm to find a special planting.

Cheng Yan! "

Liu Sichun confused: "His Royal Highness does not mean that it is afraid of cold? If it is frozen in cold today, how can it be planted?"

Li Chen laughed and said, "There is a technology, named a warm shed, you can plant spring and summer fruit in autumn and winter. It is amazing. When the palace is promoted, it is not unusual to eat watermelon in the cold winter.

"

"Is there such a magical thing in the world?"

Liu Sichun turned around, and she asked curiously: "How did His Royal Highness know these?"

"It seems to be in the book."

Li Chen waved his hand and found an excuse and sent it away.

"This matter, you made merit, what reward?"
