"Whew, whew, whew."

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

"Damn, this time Lao Tzu jumped to P City." Thinking of this, Li Chen's consciousness body twisted, as if jumping off a roller coaster.

"Sure enough, Bo Yibo's bicycle turned into a motorcycle." Li Chen looked at the terraced fields in front of him, and his heart was excited.

The landing point has always been People's Square, and People's Square, as a commercial area, can bring limited help to Li Chen in addition to luxurious life.

In front of him was a rice field, and it seemed to be the harvest season, and the heavy ears of rice seemed to be made of gold.

"Hybrid rice, Grandpa Yuan, I love you to death." Li Chen was ecstatic in his heart, hybrid rice would inevitably cause an uproar in Daqin.

"Rice, sweet potatoes, potatoes, corn." He could only carry about a hundred catties of things at a time, and Li Chen chose these four crops.

There were five main grains for the people of the Qin Dynasty, namely millet (millet), wheat, millet (rhubarb rice), rice, adzuki (adzuki bean) and soybean (soybean). The fields are divided into upper, middle, and lower according to the degree of fertility. There is no need to rotate ploughing in the field, and the yield per mu is 250 catties. Zhongtian should be planted for 1 year and 1 year off, and the yield per mu is 200 catties. It takes 1 year to plant and 2 years off in the field, and the yield per mu is only 140 catties.

Most of the common people eat millet and wheat as their staple food. Because millet and wheat do not need much watering, they are suitable for the drier lower and middle fields. In the Qin Dynasty, the land granted by the Qin Dynasty was generally 2.4 times that of the upper field.

To the south of the Qinling Mountains, large tracts of fertile land with abundant rain are used to grow higher-yielding rice. The taste of rice is better than that of millet and wheat, and it is used as a ration for nobles.

The yield of hybrid rice on the earth is 1,600 catties, the yield of potatoes is 2,000 catties, the yield of sweet potatoes is as high as 5,000 catties, and the yield of corn is 3,000 catties. The land of Great Qin is naturally not comparable to the earth, even if it is discounted in half, it is more than enough to feed Great Qin, who only has a population of 20 million.

There are two kinds of national civilizations in Chinese history, one is the civilization of cultivation and reading, and the other is the civilization of cultivation and warfare. And Daqin is undoubtedly an out-and-out civilized country of cultivation and warfare.

Food and population are the two most important factors in cultivating a civilized kingdom.

Farmers farm, harvest, can feed more people, and then have children. The child grows up, farms, harvests, and has children again.

Hybrid rice, corn, sweet potatoes, and potatoes can make farming and having children a perfect closed loop to ensure the population and food of the Qin state.

Xianyang, suburbs, Lijiazhuang

"The lord's family is crazy, and all the good millet seedlings in the field have been pulled out."

"It's said that we want to grow some new grain from overseas."

"Overseas, isn't that where the gods live, could it be that the main family wants to plant the gods to eat."

"It's autumn now, and I can't grow anything."

"The lord also poured manure into the ground, saying that he wanted to fertilize the fields."

"Can you still eat that smelly thing?"

Since beating Li Chen and asking the big cow to pull out the seedlings in the sky, the big cow and the Hun slaves took turns to pick up dung in the field all day long, and it was rumored in the Zhuangzi that Li Chen was crazy.

"Boss, when you built that public thatched house, were you calculating?" Da Niu poured the last bucket of dung into the ground and said depressedly. A few big men, all covered in stinking.

"You know what, this is called Fat Field. Tomorrow, when the dung has gone down, you will plow the fields. Li Chen commanded.

"Boss, it's nothing to let me do this dirty work, can you tell me about it. My whole person is in the clouds, and now the people in Zhuangzi look at me as fools. "Da Niu was a little depressed.

"You take care of these experimental fields, and we will plant the seeds in a few days, and I guarantee that the yield per mu will be at least double." Li Chen explained.

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

"The fields in our Lijiazhuang are all medium fields, and if they are on the fields, it is not impossible to double or triple them." Li Chen sighed.

"That boss, I think there is still some dung in those huts, I'm going to take a look." Da Niu, an old farmer, heard that the yield per mu could reach more than 500 catties, and he immediately couldn't care about the smell and tiredness.

"Cut all these potatoes into cubes and not be too big. The big knife should be rubbed with wine first, and you will pierce the eyes of the six sons, and each potato will pierce two eyes. ”

"In the No. 1 field, the soil should be deep, the six sons are not too shallow, come to the big cow, dig deeper."

"Big cow, sweet potatoes can't be cut like this, sweet potatoes should be large."

"Yes, the size of five potatoes."

"Plant sweet potatoes at intervals, yes, at a larger interval, and keep them even."

"No. 2, yes, No. 2 grows sweet potatoes."

"The corn is planted in the same way as soybean (soybean), which is planted in the No. 3 field."

Li Chen moved a recliner and slept in the shade of the trees at the head of the experimental field.

"The landlord's old wealth." When Da Niu passed in front of Li Chen, he muttered in the novel.

"Is the landlord happy, do you think the landlord is as fast as you think."

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

Potatoes can be grown in at least three months in just three months, regardless of the fertility of the field. The ripening period of sweet potatoes is four to five months, and two crops can be planted in a year, and corn is also about four months, and there is no problem in planting two crops a year.

If nothing else, Li Chen will soon become the largest landlord in the entire Great Qin. And Li Chen, who has mastered the new crop and grain varieties, has undoubtedly become the one who grabbed Daqin's throat. This is both a good thing and a curse.

These experimental fields grow more than just sweet potatoes, potatoes, and corn. This is Li Chen's net worth, and it is also the future of Daqin. This kind of thing that can change the fate of Great Qin must be in the hands of the First Emperor. And Li Chen is still not in the eyes of the First Emperor at this time, Li Chen is waiting, waiting for Yingyue to come back to accept this big surprise.

In the evening, several people who had finished their work gathered around to have dinner.

"Da Niu, from tomorrow onwards, you will take someone to show me the experimental field day and night, and the contents must not be leaked until the princess returns." Li Chen said to Da Niu.

"I know, I'm sincere, and I'm not stupid." Big Niu muttered as he stuffed the potato beef into his mouth.

That's right, the potatoes on this table are the grain seeds that Li Chen deducted. Eating delicious potatoes and beef, Li Chen also experienced the fun of African compatriots.

As for beef, yes, it is illegal for Daqin to kill cattle. But as an upper-class person, is it normal to occasionally eat some tired and sick cows? It's just that the coffin board of this cow is a little unbearable, and you are dying of illness and exhaustion.

"Boss, we still have some bricks in our brick factory. Let's put a wall on the experimental field, there are always people to see it, and I don't feel sure. The bull kept watch for a day, and on the second day he proposed.

The next day, Li Chen gathered the idle tenants, tired of a three-meter-high wall, and surrounded the entire experimental field. Several blue brick houses were built in it, and a few experienced old farmers were specially transferred from the Dharma Academy. The newly built courtyard also hung a large plaque with three big characters on it: "Academy of Agricultural Sciences".
