Xu Jishan?

Zhu Changluo was slightly in a trance, and only reacted after a while, Wang An was talking about Xu Guangqi, the agricultural master who was brought back by him when he first arrived in Ping'an Mansion, and now he is placed by Zhu Changluo in the mansion as a discipline worker.

But he just hung a title, after Zhu Changluo invited him back, he drew a separate boundary in the palace, let him toss in the middle, and the direction of the main attack is potatoes.

In Zhu Changluo's memory, the Wanli Dynasty was already the last glorious era of the Daming, and it was followed by the Xiaoice Age, which indirectly drew a stop for the Daming, and with the rapid change of climate, the frequency of various floods, droughts, plagues and earthquakes increased greatly.

For an agrarian civilization, there is no more terrible disaster than a large-scale natural disaster!

This is also the biggest reason why Daming was unable to support it in the end, and the only opportunity to change this situation is to introduce new crops that can increase the yield per mu on a large scale, and potatoes are one of the big killers.

And Zhu Changluo vaguely remembered that potatoes were introduced to China in the Wanli Dynasty, and first began to be planted in Jingshi, with the mentality of giving it a try, before Zhu Changluo left, he ordered people to look around Beijing, and really let him find the seeds of potatoes.

However, it makes him regret that this obviously new crop is not valued by anyone in Beijing, people are used to grains as a staple food, and they are not interested in this kind of tasteless thing at all, especially when the people find that planting potatoes will greatly reduce the fertility of the land, and after a long time will give birth to tender buds and become toxic, no one wants to plant it......

Zhu Changluo is also very helpless about this, after all, what vision can the common people have, although the Ming Dynasty is not Haiyan Heqing now, but it is finally smooth, especially the people of Beijing, there are very few disaster years, there is rice, wheat to eat, who wants to eat potatoes such a tasteless thing?

He had to temporarily plant the potatoes in two large vats and bring them to Ping'an Mansion together, but he was not a professional in this after all, so the first thing he did when he arrived in Ping'an Mansion was to find Xu Guangqi and ask him to serve these potato seedlings well, and then promote them on a large scale after accumulating a certain amount of production experience......

It's just that what is Xu Guangqi doing now? Could it be that the potatoes are already ripe?

"Minister Xu Guangqi has seen His Highness!"

Pressing the doubts in his heart, Zhu Changluo called Xu Guangqi in, but found that his face was indeed not very good.

"Mr. Xu doesn't have to be polite, but there's something wrong with the potatoes?"

For an agronomic celebrity like Xu Guangqi, Zhu Changluo has always been very respectful, and he doesn't ink, and he asks about business as soon as he opens his mouth.

"The minister is ashamed, and he has the high hopes of His Highness!"

Xu Guangqi drooped his head, looking weak, Zhu Changluo for him, it is simply the grace of recreation, not only solved his food and clothing problem, gave him an official position, but also vigorously supported his research on agriculture, the so-called life has a confidant, death without regrets, Xu Guangqi obviously regards Zhu Changluo as his confidant at the moment, and feels that he can only live up to his reuse if he works hard to do what Zhu Changluo handed over to him.

However, the ugly daughter-in-law also wants to see her in-laws, Xu Guangqi still said stubbornly.

"The potatoes brought by His Royal Highness are indeed good seeds, the maturity period is short, the yield per mu is high, the first batch of potatoes is now ready to be harvested, but the minister is incompetent, and the yield per mu is only 1,000 catties under the reluctance, and this thing is very hurtful to the land, planting a season of potatoes, at least one year can not plant other things, need to raise the land......"

Thousands of pounds per mu!

It seems to be a very remarkable achievement, you know, the yield of rice and wheat per mu is only about 200 catties, and the yield of potatoes is close to ten times.

But Xu Guangqi is very clear, this is not cost-effective at all, although the yield of potatoes per mu is 1,000 catties, and it only takes about 70 days to mature at the earliest, but it hurts the land, and in order to produce this 70 days, it is necessary to delay the land for a whole year.

And if this whole year is used to grow wheat, the combined cultivation of winter wheat and spring wheat can produce at least 500 catties, and you must know that rice and wheat are the staple foods today, and their price and role are not comparable to potatoes.

So it's a loss-making deal.

Let alone...... Xu Guangqi clearly remembered that when Zhu Changluo handed over the potato seedlings to him, he swore that the yield of potatoes per mu could reach at least 2,000 catties, but now it has only reached half of the target, how can Xu Guangqi not feel guilty?

He didn't believe that with the respect of Prince Zhu Changluotang, he would lie to him on such a trivial matter!

"Thousands of catties per mu?"

Zhu Changluo frowned, but also slightly unexpected, he naturally knew the difference between a thousand catties and two thousand catties, if the yield per mu is 1,000 catties, then the potatoes do not have the value of promotion at all, and two thousand catties, even if it tastes bad, even if it hurts the ground, but it does not prevent it from being used as a ration for disaster years, after all, the yield is twice as high!

"Take this king to see ......"

Zhu Changluo stood up and said to Xu Guangqi.

This is not a small matter, if he can't even use a big killer like potatoes, then how should he deal with the next Xiaoice River period?

Xu Guangqi's small courtyard is actually a very large place, and when Zhu Changluo built the palace, he deliberately asked Wang An to set aside five acres of fertile arable land in the middle as a test field.

He also deliberately found many farmers to help Xu Guangqi farm together, and he was not wrong.

It is indeed almost the harvest season of potatoes, Zhu Changluo stood on the edge of the field, looking at the farmers below happily harvesting potatoes, but his brows couldn't help frowning.

Because he found that Xu Guangqi did not lie to him, two acres of potatoes had been harvested, and the yield was indeed much worse than he expected, but what went wrong?

Zhu Changluo picked up a potato on the ground and found that it had grown very small, not at all full as he remembered, and the root part had rotted in some places, just dug out of the ground, and still damp......

Wait, Zhu Changluo patted his head, with a look of chagrin on his face, how could he forget the allusion of the southern orange and the northern orange, and actually made such a low-level mistake!

Potatoes are drought-tolerant and cold-tolerant and do not pick the ground, and can be planted in the case of very bad land, but it has a very serious shortcoming, it is not waterlogged, in short, potatoes are afraid of water, if the land is too humid, it will lead to a lack of oxygen in the underground root system of potatoes, and then rot, and the entire Nanzhili is a place in the south of the Yangtze River, the land is fertile, needless to mention, and more importantly, the rainy season is overflowing, in this case, potatoes can grow well is strange!

Thinking about it carefully, it seems that in later generations, the main production areas of potatoes were also Inner Mongolia, Northeast China and other places with drier climates......

Annoyed, Zhu Changluo was also depressed, waved his hand and said.

"This matter is taken for granted by this king, and it has nothing to do with Mr. Xu, it seems that the land south of the Yangtze River is not suitable for potato planting, even if it is Mr. Cai, it cannot compete with the number of days!"

Xu Guangqi can't be blamed for this matter, he actually reported to Zhu Changluo before that the growth of potatoes in the palace is not good, but Zhu Changluo was brainwashed by the miraculous yield of potatoes, and insisted that Xu Guangqi continue to work hard, and it is understandable to cause such a result.

After a pause, Zhu Changluo was about to turn back, but his gaze was nailed by a small, purple-red object......
