Lu Xuan looked at Zhang Zhao's suspicious look and smiled softly.
He has already lowered his voice.
In this era, there were no growth-promoting fertilizers such as urea and phosphate fertilizers. Considering the different conditions of the land, Lu Xuan went lower 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 chemical fertilizers to promote growth, the yield of sweet potatoes per mu is 6,000 to 7,000 kilograms, which is normal, because these things can grow so well. A sweet potato vine can produce 10, 20 kilograms.
Sweet potatoes are perfectly normal.
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 the king can ask anyone at will."
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. In more than two months, sweet potato seedlings will be ready. In May and June, sweet potato seedlings will be ready."
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, Sheng Ming."
The planting methods mentioned by Lu Xuan are more detailed than those mentioned by the merchants, which is enough to prove that Lu Xuan really understands.
Zhang Zhao hesitated when he saw Lu Xuansha's serious look. His life experience and experience told him that the yield of sweet potatoes was impossible. However, Lu Xuan had never failed since he started to rise.
As a result, Zhang Zhao also had some doubts.
Zhuge Liang took over 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, so you need to plant one acre."
The ground may be difficult."
Lu Xuan shook his head and said: "This sack of sweet potatoes will be enough for the seedlings, not to mention one acre of land, and another ten acres of land."
Zhuge Liang scratched his head and looked at the sweet potatoes carefully.
He thought this was strange.
Is it possible?
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 continue to 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."
When Zhuge Liang heard this, his heart started to beat loudly. He was very excited and solemnly said: "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 Xuanyuan clearly explained the sweet potato situation, 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 sweet potatoes don't grow seedlings, so 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 eaten in 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 item and gave a general introduction. However, he didn't know much about the specific method of eating it and the specific situation, but the king knew it very well.
He is worthy of being 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 has higher soil quality requirements. 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 is not a high-quality crop, and it is not produced by chemical fertilizers. Even 800 kilograms is not bad.
Lu Xuan saw Zhuge Liang and Zhang Zhao's slightly numb expressions, and said with a smile: "Don't underestimate corn. When corn is just mature, you can cook it and eat it. It tastes very good. After the corn is dried, it can be threshed and dried in the sun, and it can also be ground.
You can eat it with flour 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 in it. But he didn't know the red pepper in the other bag. He said, "Your Majesty, what is this red one?"
Lu Xuan replied: "This is chili pepper. It has similar effects to dogwood, but it is spicier and more fragrant than dogwood. With chili pepper, food will have more flavor. Although chili pepper is not a crop and cannot solve the famine, we must pursue food.
Delicious, this is necessary.”
Zhuge Liang nodded, not showing 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.
, so that it can be harvested three times 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 Zhao 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 a little difficult to adapt to the situation.
