"Hu, Hu, Hu."

It was the kind of weightlessness that I was riding a roller coaster, and Li Chen once again saw the blue planet in front of me.

"Damn it, I jumped into P City this time." Thinking of this, Li Chen's consciousness twisted, as if he had jumped off the roller coaster.

"It turns out that Boyibo bicycles turned into motorcycles." Li Chen looked at the terraces in front of him and felt excited.

The People's Square has always been the place. As a commercial area, the People's Square can bring limited help to Li Chen in addition to its luxurious life.

In front of me is a rice field. It seems that it is the season of harvest, and the heavy rice ears are like gold.

"Hybrid rice, Grandpa Yuan, I love you so much." Li Chen was ecstatic. Hybrid rice would inevitably cause an uproar in Daqin.

"Rice, sweet potatoes, potatoes, corn." Li Chen chose these four crops.

There were five main types of grains for the people of the Qin Dynasty, namely millet (millet), wheat, millet (black yellow rice), rice, lily (small beans) and beans (soybeans). The fields were divided into upper, middle, lower, and upper fields according to their fertility. The upper fields did not need to be rotated, and the yield was 250 kilograms per mu. The middle fields should be planted for one year and rest for one year and the yield was 200 kilograms per mu. The downfields should be planted for one year and rest for two years, and the yield was only 140 kilograms per mu.

Most ordinary people use millet and wheat as their staple food. Because millet does not require too much watering, it is suitable for drier lower fields and middle fields. However, the Qin Dynasty taught land, and the lower and middle fields were generally two or four times that of upper fields.

South of the Qinling Mountains, large areas of land with fertile land and abundant rainfall are planted with higher yields. The taste of rice is better than that of millet and wheat, which is a food for nobles.

The yield of hybrid rice on the earth is 1,600 kilograms per mu, the yield of potatoes is 2,000 kilograms per mu, the yield of sweet potatoes is as high as 5,000 kilograms per mu, and the yield of corn is 3,000 kilograms per mu. The land of Daqin is naturally not as good as the earth, and even Daqin, which only has a population of 20 million, is more than enough.

There are two types of national civilizations in Chinese history: one is farming and reading civilization, and the other is farming and fighting civilization. The Qin Dynasty is undoubtedly a country that is farming and fighting civilization.

Food and population are the two most important factors in farming and fighting the civilized kingdom.

Farmers can feed more people and then have children when they grow up, farm, harvest, and have children again.

Hybrid rice, corn, sweet potatoes, and potatoes can make farming and having children a perfect closed loop that ensures the population and food of the Qin State.

Xianyang, suburbs, Lijiazhuang

"The master is crazy, all the fine grain seedlings in the field have been pulled out."

"It is said that we need to plant some new grains from abroad."

"Overseas, isn't that the place where the gods live? Could it be that the main family wants to plant the gods eat?"

"It's already autumn, and nothing can be planted."

"The owner also poured the feces into the ground, saying that he wanted to make the field rich."

"Can the smelly things be eaten?"

Since Li Chen asked the big bull to pull out the seedlings from the sky, Da bull and Hun slaves took turns to the field to pick up manure all day long. There were rumors in the village that Li Chen was crazy.

"Boss, when you built that public cottage, were you just calculating me?" The big bull poured the last bucket of manure to the ground and said depressedly. Several big men were covered in stench.

"What do you know? This is called fat fields. When the manure is fermented tomorrow, you can plow the fields." Li Chen ordered.

"Boss, it's nothing to ask me to do this dirty work. Can you tell me about it? I'm confused. Now the people in the village see me and I'll show the fool." Daniu was a little depressed.

"Please take good care of these experimental fields. We will plant the seeds in a few days. I will ensure that the yield per mu is at least." Li Chen explained.

"Boss, you didn't lie to me." Daniu asked in disbelief.

"The fields in our Lijiazhuang are all middle fields. If they are upper fields, it is not impossible to turn them twice or three times." Li Chen sighed.

"That boss, I think some manure can be taken from those thatched cottages, so I'm going to see it." Daniu, a man from an old farmer, heard that the yield per mu could reach more than 500 kilograms, and he was immediately disregarded the smell and fatigue.

"Cut all these potatoes into pieces, and don't be too big. You should apply a big beef knife with wine first. You can tell the eyes, and each piece of potato is two."

"In the field No. 1, the soil should be deep. The sixth son cannot do it too shallow. Come on, dig deeper."

"Big beef, sweet potatoes cannot be cut like this, sweet potatoes need large chunks."

"Yes, the size of five potatoes."

"There should be intervals for planting sweet potatoes, right, the intervals should be larger and keep them even."

"No. 2, right, no. 2 to grow sweet potatoes."

"The method of planting corn is the same as that of beans (soybeans), and planted in the third field."

Li Chen brought a lounge chair and slept under the shade of the trees on the experimental field.

"The landlord is rich." The novel muttered as the big bull passed by Li Chen.

"Are the landlords happy? Do you think the landlords are as fast as you imagined?"

"No, you can't imagine the happiness of the landlord." Li Chen retorted.

The maturity period of potatoes only takes three months. Without considering the field strength, you can plant at least three seasons a year. The maturity period of sweet potatoes is four to five months, and you can also plant two seasons a year. Corn is also about four months, so there is no problem planting two seasons a year.

If nothing unexpected happens, Li Chen will soon become the largest landlord in the entire Qin Dynasty. Li Chen, who has mastered the new crops, undoubtedly became the person who pinched Da Qin's throat. This is a good thing and a disaster.

These experimental fields are not only sweet potatoes, potatoes, and corn. This kind of planting is Li Chen's life and life, and it is also the future of the Qin Dynasty. This kind of thing that can change the fate of the Qin Dynasty must be in the hands of the First Emperor. Li Chen is still unable to see the First Emperor's Dharma at this time. Li Chen is waiting, waiting for Ying Yue to come back to accept this big surprise.

At night, several people who had finished their work gathered together for supper.

"Da Niu, from tomorrow on, you will take people to watch the experimental field day and night. The things in it must not be leaked until the princess comes back." Li Chen said to Da Niu.

"I know, I'm honest, not stupid." Da Niu muttered while stuffing potatoes and beef into his mouth.

That’s right, the potatoes on this table are the grains that Li Chen deducted. After eating delicious potato beef, Li Chen also experienced the fun of his African compatriots.

As for beef, it’s good. It’s illegal to kill cattle in Daqin. But as an upper class, it’s normal to eat something that is exhausted occasionally. What’s more, the cow’s coffin board is a bit uncontrollable. You are the one who dies of illness.

"Boss, our brick factory still has some bricks. Let's build a wall for the experimental field. If someone always goes to see it, I feel uneasy." Daniu guarded the ground all day and suggested the next day.
