After everyone discussed for a while, His Majesty Li Er waved his hand and said: "My Datang is mainly agriculture, if I really succeed in planting this corn this time, my Datang national strength will be even stronger." What I mean is to let Chu Ze be responsible for finding seeds from Nahu Shang, and Yang Aiqing will assist in finding a piece of fertile land to try planting first, if the yield per mu is really high, and then promote it in all provinces of my Datang. ”

All the people are called holy.

The eldest grandson Wuji said: "Yangquan County, can you know these agricultural things? ”

Chu Ze said: "Xiao Ke likes to read all kinds of books, and he knows a little bit about this farming." ”

Wei Zheng said: "These new crops are not familiar to the people of Datang, if they are promoted, it may be a lot more difficult, can Yangquan County have a countermeasure?" ”

Chu Ze said: "This matter is very simple. His Majesty can issue an order to order experienced old farmers from all over the country to come to Beijing to learn the planting methods of new crops, and return to their hometowns to teach them after they have learned. ”

After Chu Ze finished speaking, Wei Zheng nodded and stopped talking.

Fang Xuanling said: "These crop seeds are all from foreign countries, if they are harvested in one season, can the fruits be planted again?" ”

Chu Ze said: "In my opinion, when a yamen for the cultivation and improvement of crop seeds is set up, not only new crops, but also some of the original crop seeds of my Datang can also be improved. Xiao Ke has read a lot of agricultural books and has a lot of experience in this area. The seed problem can be solved. ”

His Majesty Li Er smiled and said: "Okay, okay, how can it be like a three-hall trial, Chu Ze is for the people, so don't ask any more questions." The crowd sang a promise.

After the matter of the seed was settled, His Majesty Li Er looked at the crowd, "I don't know what do you think about the governance of the Yellow River this year?" ”。

Since ancient times, the Yellow River has been plagued by disasters, and almost every year or two, there will be floods. The Qinling Mountains and the banks of the Wei River, an important tributary of the Yellow River, are the hardest hit areas. In the more than ten years since the founding of the Tang Dynasty, tens of thousands of people have drowned, and many surrounding villages and towns have been flooded, and countless houses have been flooded.

"Your Majesty! The flood of the Yellow River is mainly due to the siltation of the Yellow River, taking advantage of the drought and lack of water, the width of the water surface is greatly reduced, and a large number of laborers are recruited to dig up the sediment in the dry river and accumulate the sediment on the embankment, which is the best way to control the flood of the Yellow River. In this way, the riverbed will not be raised year after year. Cen Wenwen took the lead in saying.

"Your Majesty! Do you think this method is useless? Given the width and length of the Yellow River, if this move is to be effective, it will probably require millions of laborers to be conscripted and tens of millions of financial resources to be effective, and if the number of laborers is too small, there is no doubt that it will be a drop in the bucket, and even if it is effective, I am afraid it will have little effect. Therefore, the minister suggested that the lower reaches of the Yellow River should be divided into two parts, and the flooding of the Yellow River should be controlled by the method of dividing the river. The eldest grandson Wuji said.

"Your Majesty! The minister has already ...... "Cen Wenwen and the eldest grandson Wuji have been arguing for a while, and the literati are light on each other, so there are often arguments in the civil official group."

Looking at the two arguing endlessly, His Majesty Li Er finally felt impatient, waved his hand to interrupt the two, looked at Wei Zheng, who was not speaking, and said, "What do Wei Aiqing and Fang Aiqing think?" ”

Wei Zheng took a step forward, bowed down and said, "Your Majesty! The minister thought that Lord Cen's method of digging sand had never been used before, and he would talk about it after verification. ”

His Majesty Li Er nodded, his face was a little unnatural, thinking to himself how to verify this, could it be that millions of laborers were used to dig sand, and the people's crops were left alone, and then I emptied my already abundant treasury?

Fang Xuanling saluted His Majesty Li Er and said, "Return to Your Majesty!" Although it would cost a lot of money to raise the embankment and a lot of labor, it would be much less than the method of dredging. Therefore, for the sake of safety, the minister thought that the embankment should still be raised this year. As for the method of sand dredging, I thought that I could wait for a few years, when the national strength of my Datang Dynasty became more and more prosperous, and the treasury became more and more abundant, and then consider this method to see how effective it was. ”

His Majesty Li Er nodded, although Fang Xuanling didn't say anything more useful, but what he said was safe. However, this still did not achieve his goal of saving a lot of money and trying to reduce the number of servitudes as much as possible.

His Majesty Li Er thought for a while, swept his gaze to Chu Ze, who was bowing his head on the side, and said lightly, "Chu Ze, what do you think?" ”

Chu Ze raised his head and saluted everyone, "Where what Xiao Ke said is right or wrong, I hope you adults don't blame it!" ”

His Majesty Li Er waved his hand and said, "But it's okay to say it!" ”

Chu Ze thought for a while, then shook his head and said: "The method of digging sand must not be done!" ”

"Why?" Without waiting for His Majesty Li Er to speak, Cen Wenwen glared at Chu Ze and asked dissatisfiedly.

How to dig sand......... In the future, Chu Ze had never heard of the government using this method to control the floods of the Yellow River, so it can be seen that this method is absolutely ineffective.

The Great Demon King Cheng knew that Chu Ze probably didn't know Cen Wenwen, so he said: "This is Lord Cen, a scholar who has governed the Yellow River over the years. ”

Chu Ze organized his rhetoric and asked Cen Wenwen: "Dare to ask Lord Cen, there is also the Yellow River in Lanzhou in the northwest and the Yinxia area where the party departments are located, why don't you see these places to increase the embankment every year?" ”

"Of course, the water is different from the rapid, and the sediment does not sink." Cen Wen has been governing the river for many years, although he has had little effect, mainly because he has continued to increase the embankment. However, the specific reasons for this have been carefully studied. It's a pity that he only knows one thing, but he doesn't know the other. The truth of this is not fully recognized.

"And the method of dredging sand is the method of curing the root cause, how can it not be done." Cen Wenwen looked at Chu Ze, and then said. I thought to myself what you know about a weak-crowned child with no hair on his mouth, and he really doesn't know what the sky is thick and hairy.

Chu Ze said: "As we all know, the water of the Yellow River, a bowl of water and half a bowl of mud, in autumn, is seven points of sand and three parts of water. Let's not talk about how much labor is required to dig sand, how much financial resources the imperial court will spend, whether the people can stand it, and whether the finances can support it. ”

After a pause, Chu Ze continued: "Even if the sediment is dug up during the drought season, when the rainy season comes, the waters of the Yellow River will be widened, and the dug up sand can be silted up again in just a few days." If you don't believe it, you can dig a small canal and introduce the water of the Yellow River to conduct an experiment. Chu Ze also saw that this Lord Cen was dissatisfied with him, but he didn't care too much.

Cen Wenwen's expression was stunned, he couldn't speak for a long time, he just thought that he would go back and dig a small ditch to test it according to the method Chu Ze said.

In addition, the method of sand dredging requires a huge amount of labor and financial resources, but over the years, he has studied the management of the Yellow River floods, in addition to raising and reinforcing the embankment, it seems that the only method of sand dredging is the only method. As for the diversion method mentioned by the eldest grandson Wuji, in his opinion, it is pure.
