After three rounds of drinking, Chen Jinglun opened his mouth first.

He got up and stepped forward, filled a glass of wine for Wang Zaijin, and asked, "Sir, is it the matter that I asked you about last time, and there is a reply from the palace." ”

After receiving this glass of wine, Wang Zaijin raised his beard with satisfaction.

"It's not that you don't know that the palace has put its mind on a wealthy businessman with a big business."

"First of all, Jinyiwei was in charge of supervising the division, and then Li Shi, the eunuch who asked the draft girl to come back, went to manage the weaving bureau..."

Chen Jinglun was taken aback when he heard more than the second thing.

"Suzhou weaving has also been replaced?"

"You don't know yet?"

Wang Zaijin nodded and snorted coldly: "Among the many businessmen, you are still late. The others had sources everywhere, and as soon as the news came out in the palace, they were all clear. ”

"At present, it is only Suzhou weaving, Hangzhou weaving, Jiangning weaving, sooner or later have to be replaced."

"I took the meaning of the palace and presided over this sweet potato. You say, do you need an obedient commander? ”

The more he listened, the more shocked Chen Jinglun became.

"Sir, how do you want to promote sweet potatoes?"

"The palace is only more interested in sweet potatoes, whether this interest can be turned into a decision depends on whether your Chen family is sincere."

Saying this, Wang Zaijin smiled slightly and said no more.

Chen Jinglun's eyes rolled, he got up and paced back and forth, and after thinking for a long time, he decided and made a decision, success or failure.

"One husband cultivates the field, and the yield of sweet potatoes per mu can be more than thirty stones!"

Hearing this, Wang Zaijin's expression moved, and he became a little excited, and after a while, he calmed down again, took a sip of tea, and asked quietly:

"Is that serious?"

"My Chen family has been promoting sweet potatoes in Fujian for more than ten years, how can there be a fake?" Chen Jinglun said subconsciously.

Why did Wang Zaijin suddenly become a little excited, because he saw an opportunity to completely solve the famine in various places!

You must know that the current yield of rice and wheat per mu is indeed not very impressive.

According to the third volume of the "Hejian Chronicles": "A husband cultivates thirty or fifty acres of land, and harvests more than one stone of wheat per mu." ”

At this time, the yield of rice per mu in the rice and wheat fields in the south, such as Wujiang, Kunshan and other places, should be two stones per mu of rice, so it is converted into a yield of about 300 catties per mu in later generations.

"The Book of Supplementing Agriculture" also contains: "The field is extremely ripe, the rice is three stones, and the spring flowers are one and a half stones, and then there are them." Dayun has a total of three stones for Chang Er. ”

The ripe fields mentioned above are "three stones" of rice and "one and a half stones of spring flowers".

Then, the rice yield of Changtian is about two stones per mu, and the yield of spring flowers is one stone per mu, and the total yield is three stones per mu.

This is the south, the current north, due to the impact of the Xiaoice period, the wasteland is in patches, the people have no land, forced to flee everywhere, and the production is less.

According to the records of Fang Zhi, the Ming Dynasty introduced sweet potatoes from Fanwai, not only Chen Zhenlong of Fujian.

In addition to him, there are also Lin Huailan from Wuchuan and Chen Yi from Dongguan, which were introduced from Annan, but they have always been local and regional, and they have not been able to achieve large-scale promotion.

Since the end of Wanli, Shaanxi, Henan, Beizhi, Shandong, Guangdong, Guangxi, Fujian, and Yunnan have begun to introduce sweet potatoes.

It's just that there is still a long way to go from introduction to popularization.

What Wang Zaijin needed to do was to persuade the emperor to attach importance to sweet potatoes, start trial planting in the form of imperial decrees, and then promote them in the Ming Dynasty, Beijing, and Thirteen Provinces.

So what's the difficulty?

Since sweet potatoes have long appeared, but they have not been popularized so far, there must be a reason, before Shangshu was given to the emperor, Wang Zaijin had a lot of hard work.

The implementation of sweet potatoes to solve the famine has blocked the financial path of some people, but the bigger reason is that most of the people at the bottom do not know the advantages of sweet potatoes at all.

The promotion of sweet potatoes is a detrimental practice for local officials when they do not receive a clear decree from the imperial court.

Most of the magistrates planted only temporarily, and after alleviating the local famine, they seldom planted them again to avoid suspicion.

After all, there are too few people who directly ordered the promotion of the whole province like that.

Wang Zaijin understood that without seeing the true yield of sweet potatoes and before the emperor's clear decree was issued, sweet potatoes could only be implemented on a small scale in a certain place, which could not meet the current demand for alleviating the famine.

Wang Zaijin and Chen Jinglun talked for a long time about the implementation of the national policy of sweet potatoes.

said that it was for the implementation of the national policy, but both of them were like Spiegel in their hearts, they each had their own interests, but they were just for a common goal.

In this world, how can there be so many selfless, for the country and the people.

......

A few days later, Wang Zaijin, as a cabinet minister, presented Zhu Youxiao to "play sweet potatoes and promote sparseness", which caused an uproar.

For a time, the official of science and Taoism impeached the king in the middle of the Jin Dynasty to enter the cabinet, and the inscription that did not conform to the etiquette law also flew to the Xinuan Pavilion like snowflakes.

Xinuan Pavilion, the new manager of the Qianqing Palace, Wang Chaofu, is cleaning up the sparseness for the emperor and picking those "urgent matters".

He flipped through it and found that the revelation posts of the Taoist officials were still the same, either to criticize Yan and scales, or to impeach Xiong Tingbi and Wang Zaijin, there was really nothing to think about.

After a while, he pulled out a piece of music and said happily: "Your Majesty, the scholar of Dongge University is in Jin, please promote sweet potatoes." ”

The wide robe with large sleeves, the jade belt and the gold jacket, and the gorgeous clothes have become a burden at this time.

For the first time, Zhu Youxiao's mouth rippled with such a bright smile, and as soon as he took this piece of music in his hand, the more he looked at it, the more he sighed.

"Yes, yes!"

Zhu Youxiao looked at this recital very seriously.

This "Playing Sweet Potato to Promote Shu" is easy to understand, and I think about it, Wang Zaijin also conducted a detailed survey in the local area before Shangshu.

Wang Zaijin combined the planting experience shared by Chen Jinglun with his farming experience when he walked in Gyeonggi and other places, and came to the conclusion that sweet potatoes are easy to grow and the yield per mu is higher than that of rice and wheat.

Shu Zhongyun: "The implementation of sweet potatoes is a necessary national policy for this dynasty." ”

Zhu Youxiao also knew that at this time, sweet potatoes had been widely planted in South China and gradually promoted to the north.

Not only to promote sweet potatoes, but also to promote potato Rihui, first fill the stomach, before we can talk about the problem of opening up sources and reducing expenditure.

There are some things that can't be caused at the bottom.

Historically, due to the influence of the war in the late Ming and early Qing dynasties, although sweet potatoes entered the Ming Dynasty earlier, the spread of cultivation technology has been very slow.

In the Kangxi period of the Tatar Qing Dynasty, the cultivation technology of sweet potatoes was popularized, which just allowed the Tartars to pick up a leak.

In fact, then again, the Tartars picked up fewer leaks?

Wang Zaijin said in his recital that the cultivated area of a field is not only related to the texture of the land itself, but also determined by the crops cultivated.

Sweet potatoes have strong adaptability, can be cultivated in mountainous areas where rice and wheat cannot be planted, and can also be used for wasteland recultivation, turning large tracts of uncultivable land into arable land.

In addition, sweet potatoes also have the advantages of drought tolerance, strong disease resistance, strong insect pest resistance, high yield, and can be planted in spring and summer a year.

In this regard, Chen Zhenlong's pioneering promotion in Fujian has already allowed the trial planting of sweet potatoes in Gyeonggi and other places in the coming days, and has sufficient experience.

Based on the output of Fujian in the past, the yield per mu of spring potatoes was 30 stones, and the yield of summer potatoes per mu was generally between 10 and 20 stones.

The sum of spring and summer, even in the smallest case, is forty stones.

To put it more simply, the annual yield of sweet potatoes has increased dozens of times compared with the rice and wheat with "more than one stone per mu".

It turned out that a field that could feed one person could feed dozens of people if sweet potatoes were planted.

Zhu Youxiao closed the recital, only to feel that the scene in front of him suddenly opened up.

This Wang Zaijin explained everything clearly in the song, but he did not say a word about where to try planting in Gyeonggi.

After thinking about it, Zhu Youxiao leaned back on the seat and said with a long sigh of relief:

"Spread the word to Wang Zaijin, there are five imperial villages in Tongzhou, and I will give them all to him, so that he can try to grow sweet potatoes. If the spring potato production is sufficient, it will be promoted to all Huangzhuang in Gyeonggi before the summer potato and planted in one piece! ”

"This matter, let Wang Zaijin have a snack!"

"By the way, isn't Xu Guangqi also good at it, send a Tiqi to find him, and ask him to assist Wang Zaijin to try planting."

After Wang Chaofu left, Zhu Youxiao got up and moved in the warm pavilion, and asked the little eunuch on the side:

"I have already issued an edict to Tong Zhonghua and Chen Ce to return from Liaodong, where are they now?"
