Lu Xuan looked at Zhang Zhao's suspicious look and smiled softly.
He has lowered his voice.
In this era, there were no growth-stimulating substances such as urea and phosphate fertilizers. Considering the different conditions of the land, Lu Xuan downgraded and said that the yield per mu was three thousand catties.
In later generations of sweet potato cultivation, due to the optimization of grain seeds from generation to generation, coupled with the growth of chemical fertilizers, the yield of sweet potatoes of six to seven thousand kilograms per mu is normal, because this thing can grow so well. It is normal for a sweet potato vine to produce ten or twenty kilograms of sweet potatoes.
Zhang Zhao saw Lu Xuan chuckle, as if he was laughing, but he still looked serious.
He doesn't believe it!
Zhang Zhao solemnly said: "I have read ancient books and know that there is a lot of grain. However, there has never been a kind of grain that can reach the output of three thousand kilograms. I really can't understand it. Not only the minister, but also anyone who the king can ask will find out. It’s impossible to believe.”
Lu Xuan said calmly: "Zibu, believe it or not, sweet potatoes are here, and the yield is here. Spring is starting in February now, and after more than two months, sweet potato seedlings can be grown. In May and June, sweet potato seedlings If you keep planting, you will harvest at the end of the year. The yield of food cannot be faked."
Bu Zhao said sincerely and sincerely: "Your Majesty, the Holy Ming."
The planting methods mentioned by Lu Xuan were more detailed than those mentioned by the merchants, which was enough to prove that Lu Xuan really understood.
Zhang Zhao hesitated when he saw Lu Xuansha looking serious. His life experience and experience told him that the yield of sweet potatoes was impossible. However, Lu Xuan never failed since he started to rise.
As a result, Zhang Zhao was also a little suspicious.
Zhuge Liang took the words and said: "I believe what the king said, so I will leave the planting of the sweet potatoes in this sack to me. With the king's guidance, I will plant them all and calculate the yield per acre at the end of the year. It's just a sack of sweet potatoes, and one acre must be planted. The ground may be difficult.”
Lu Xuan shook his head and said: "This sack of sweet potatoes will be enough for another ten acres of land, not to mention one acre of seedlings."
Zhuge Liang scratched his head and looked at the sweet potatoes carefully.
He thought this was strange.
Can it be done?
Lu Xuan patted the sweet potatoes and explained: "For planting sweet potatoes, I just mentioned that we need to raise seedlings. To put it simply, we cut the sweet potatoes into pieces and plant them in the soil. When the seedlings grow, we just cut them off and plant them. "
“One seedling can be planted once.”
"After the first batch of sweet potato seedlings are pinched, they will continue to germinate and can be planted. After two or three times in a row," the final seedlings will not be as good as the first batch, but they can still be used. "
"So after these sweet potato seedlings are raised, it is easy to plant more than ten acres."
"As long as the weather is good this year and the harvest is harvested at the end of the year, it is possible to harvest twenty or thirty kilograms of sweet potatoes from one seedling."
Lu Xuan smiled and said: "The reason why it is said to be the most cost-effective is here. It is cheap to plant, but the yield is huge."
After Zhuge Liang heard this, his heart started to beat loudly. He was very excited and said solemnly: "Please rest assured, Your Majesty, I will plant it well and make sure this sack of sweet potatoes is put to good use."
Zhang Zhao was even more curious.
However, he did not question it.
Lu Xuanyan explained the sweet potato situation conclusively, and it was obvious that he was not lying or deceiving him.
Lu Xuan stopped talking about sweet potatoes, took out another potato, and continued: "Planting potatoes is similar to sweet potatoes, except that potatoes don't grow seedlings. Just cut them into pieces and bury them in the soil."
"The yield of potatoes is smaller. According to the current situation, the yield per mu may be about 1,000 kilograms."
"Potatoes are very nutritious. The key is to withstand hunger. They can be eaten roasted, fried, mixed with rice and cooked, or cooked. They are all suitable for cooking. Potatoes have a wider range of applications than sweet potatoes, which is very important. of food.”
hiss! !
Zhang Zhao and Zhuge Liang gasped again.
Very shocked.
Another divine item!
Bu Zhao blinked, his heart numb with shock.
Your Majesty understands so well.
When he bought it from a barbarian merchant, he said it was a sacred object and gave a brief introduction. However, he didn't know much about the specific way to eat it and the specific situation, but the king knew it clearly.
As expected of a great king, he was born to know it.
Lu Xuan looked at the shocked expressions of several people and continued: "Whether it is potatoes or sweet potatoes, they can be used as food to solve the famine on a large scale in years of famine. Planting these can fill your stomach to a large extent. "
"Great King Shengming!"
Zhang Zhao didn't understand much, so he spoke solemnly.
Zhuge Liang looked at the corn on the side and asked proactively: "Your Majesty, what is the yield of the corn that Brother Zishan mentioned?"
Lu Xuan glanced at the yellow corn kernels and said: "The yield of corn is lower than that of sweet potatoes and potatoes, and it requires higher soil quality. Sweet potatoes can be grown in sandy soil, but corn is much worse in sandy soil. It is best to use large soil. The yield of corn is around 800 kilograms per mu."
Lu Xuan still reduced the output.
After all, it’s not a high-quality crop, and it doesn’t rely on chemical fertilizers to produce it. Even 800 kilograms is pretty good.
Seeing Zhuge Liang and Zhang Zhao's slightly numb expressions, Lu Xuan smiled and said: "Don't underestimate corn. When corn is just mature, you can cook it and eat it. It tastes very good. After the corn is ripe, it can be threshed and dried in the sun, or it can be ground into Eat the powder and make corn cakes.”
"In addition, corn is harvested in July and August. It can grow as tall as a person and can be planted with sweet potatoes."
"Corn grows on corn stalks, and sweet potatoes grow in the ground. So when the corn is harvested, the sweet potato seedlings also become the weather. The planting method of corn is similar to that of wheat and rice."
Lu Xuan said in a deep voice: "This kind of food is quite good."
Zhuge Liang admired Lu Xuan so much that he fell to the ground.
These crops are as precious as the king's, and he even knows how to plant them.
Amazing.
Zhuge Liang looked at the fifth bag. He knew the rice seeds inside. But he didn't recognize the red pepper in the other bag, so he said, "Your Majesty, what is this red pepper?"
Lu Xuan replied: "This is chili pepper. It has a similar effect to dogwood, but it is spicier and more fragrant than dogwood. With chili pepper, food will have more flavor. Although pepper is not a crop, it cannot solve the famine. But we must pursue food. Delicious, that’s necessary.”
Zhuge Liang nodded without much interest.
He hopes to increase production.
He hopes that through food, more people will not be affected by hunger.
Lu Xuan took a look at the rice seeds and continued: "The Champa rice brought back by Bu Zhi is an excellent rice seed from the south. It is planted in the southernmost part of Kuaiji County or in the Jiaozhou area. Due to the climate, it can be harvested twice a year. , or even three crops a year."
Zhang Zhao and Zhuge Liang were shocked and numb.
Two crops a year!
Three crops a year!
This is unthinkable.
Lu Xuan talked about the general situation of the grain and said in a deep voice: "Kong Ming, you must carefully collect all the grain seeds, including dried peppers. Next, I will tell you how to plant them. The first batch of grain seeds this year has been harvested. We can slowly promote it next year.”
"Here!"
Zhuge Liang agreed excitedly.
Lu Xuan's eyes fell on Bu Zhi and asked, "Zishan, tell me now, where do these grains come from?"
Zhuge Liang and Zhang Zhao both looked at Bu Zhi again.
Such a powerful seed also aroused the curiosity of Zhang Zhao and Zhuge Liang, and their eyes were even extremely hot.
For a while, it was difficult for Yi Bu Zhao to adapt.
