After the lost Xue Lang was rescued by the King of Qin, he successfully arrived at the Xuanzheng Palace. As soon as he arrived at the gate of Hanyuan Palace, before he arrived at the Xuanzheng Palace, King Qin suddenly stopped and said: "Youyang only needs to go down the stairs to enter, from the Rihua Gate or the Yuehua Gate, enter the Xuanzheng Gate, the Xuanzheng Hall is there, if you still can't find it, you can let the inner servant take you there." ”

Xue Lang said strangely: "Isn't the king going to court today?" ”

King Qin said: "As Shang Shuling, I want to go." It's just that if people see Youyang going to court with me, I'm afraid that I'll cause trouble for Youyang again. ”

It turned out to be for this!

Xue Lang said: "Xia Guan thinks that the king is too worried. If you want to say that you are afraid of being seen, you will go with the king from the dismounted bridge, and along the way, there are more people who have seen it, where is it that they are almost there before parting ways? Isn't this a thief? ”

When this word was used, His Royal Highness King Qin coughed directly. Xue Lang hadn't reacted yet, and persuaded King Qin: "Xia Guan and King Qin are selfless in their hearts, but it's just a coincidence, why hide it, it's suspicious!" It's better to go in together, and be frank! ”

King Qin nodded, glanced at Xue Lang appreciatively, and said, "Youyang is reasonable, today, I will go to the Xuanzheng Hall with Youyang." Young Yang, please. ”

Xue Lang arched his hand: "Thank you, king, please!" ”

The two entered the Xuanzheng Hall together.

The time of the last dynasty is almost there, and the ministers in the palace have almost arrived. After a while, the prince and the king of Qi also came, and as soon as the prince and the king of Qi arrived, there was a small yellow door preaching outside: "The saint has arrived!" ”

The saint Li Yuan walked in with square steps, sat on the throne, and the ministers below saluted together: "I have seen the saint." ”

"The Qing's family is flat, free of courtesy, sit down."

The ministers knelt down in their seats. As soon as he sat down, the sage asked Xiao Huangmen to pick up a letter and let Xiao Huangmen read it—

Xue Lang looked at the sparse performance a little familiar, and when he thought of the sage discussing his sparse performance when he said that the court meeting, a bad premonition surged in his heart! Listen to the beginning of the little yellow door read out again-

Sure enough, it's his sparse playing!

Well, the problem of not being able to write in classical Chinese anyway will be exposed sooner or later. The so-called early death and early superbirth, the so-called broken jar and broken fall, in short, love what's the matter, anyway, he just can't write, now that it's exposed, he will be sent to the sparse performance in the future, and he won't have to be afraid of being disliked by the people of the three provinces.

Xiao Huangmen read Xue Lang's sparse recital, Xue Lang secretly looked at the face of the civil and military forces of the Manchu Dynasty, but no one laughed at him...... Oh, except for His Royal Highness the King of Qi. His Royal Highness King Qi glanced at him mockingly, but he held back his temperament and did not ridicule Xue Lang for being uneducated on the spot.

For the mockery of the little brat, Xue Lang didn't pay attention to it at all-

Yes, His Royal Highness Li Yuanji, who has a beard more luxuriant than a middle-aged man, is actually still a young man who has not yet been weakly crowned. In Xue Lang's eyes, isn't he just a little fart? Although he is already the father of several children, it does not delay Xue Lang to regard people as little children.

After Xiao Huangmen finished reciting, Li Yuan said: "This is Xue Qing's plan and suggested measures on how to promote sweet potatoes. ”

In Xue Lang's recital, he mainly writes about the promotion plan and measures of sweet potatoes. Unprocessed sweet potatoes can only be stored for a year at most, and this is still a cold climate where cellars are built, and it is difficult to preserve sweet potatoes for a year if it is in the warm south.

In order to solve the problem of the difference between the north and the south, Xue Lang proposed the method of deep processing and processing into vermicelli. After that, as long as it is placed in a dry place, not to mention a year, it is no problem to store it for two or three years.

However, in order to process vermicelli, there is a problem of processing method. How to promote this method can be said to be directly related to the success or failure of sweet potato promotion.

Pei Lin asked: "Dare to ask Xue Jungong, how many catties of sweet potatoes can be made into one catty of vermicelli with this vermicelli?" ”

Xue Lang said: "About five catties." ”

Xiao Yu said: "In this way, the cost is not much. ”

Xue Lang said: "The high yield of sweet potatoes is destined to make the price of sweet potatoes naturally inferior to rice grains, let alone flour. Compared with rice grains, I position sweet potatoes as a material for disaster relief. It is the same as coarse grains such as soybeans and soybeans. With such a high-yield crop, it is easier to preserve when processed, and most people choose to make vermicelli in order to preserve food. ”

Everyone bowed their heads, and Xue Lang continued: "When it comes to promotion, no matter what means can compare to the rapid and powerful support of the state. The so-called upper has done something, and the lower one must follow it. As long as the measures are appropriate and steadily promoted, it is not difficult to promote sweet potatoes, and the speed will not be slow, but what I am afraid of is that the processing conditions have not kept up, so that the yield of sweet potatoes is wasted and vacant. Therefore, the minister suggested that local government offices should set up workshops for processing vermicelli and collect processing fees to maintain expenses. ”

Xue Lang analyzed the way to promote sweet potatoes in the sparse play. It is promoted in a way that leads to points and progresses layer by layer. Nowadays, there are only two places where there are sweet potato seeds, Chang'an and Weizeguan.

Taking these two places as the starting point, slowly, layer by layer, slice by slice to promote sweet potatoes. The state should set up processing workshops and strive to establish processing workshops in places where sweet potatoes are promoted, as soon as the sweet potatoes are planted.

Once the workshop is established, it will be operational when the sweet potatoes are harvested, and the processing fee can be charged in cash or converted into sweet potatoes. The harvested sweet potatoes, after being made into vermicelli, can also be supplied to the country's grain reserves, which can be described as a multi-task.

Xue Lang said: "Due to the high yield of sweet potatoes, they are actually promoted very quickly. The first batch of processing workshops in Chang'an and Weizeguan needed to be paid for by the government treasury, and the later workshops could use the early income to use the construction funds, so as to reduce the pressure on the government treasury expenses. It can also avoid the harmful consequences that may be caused by too hasty promotion, and it is also safe enough. ”

With the yield of sweet potatoes, the processing fee can be made even if it is only a penny per catty. The construction of a processing workshop is a very simple thing, where there is water, you can build a water mill, where there is no water, use donkeys, and you don't need many people, the main thing is that the place is spacious enough.

And now it is not that the population of later generations is small, but now it is still a vast and sparsely populated ancient time, and land is really not a scarce thing.

Xue Lang's sparse writing is easy to understand and well-organized, and all of the people present are well-educated, so it is not too easy to understand. Xue Lang explained it again just now, and he was already in his chest.

Li Gang said: "When the minister was ordered to go to Weize Pass to investigate the matter of Xiangrui, after hearing about the yield of sweet potatoes, he once calculated that the yield of sweet potatoes is so high, a household does not need to have many varieties, only one acre is planted, with the number of households in my Tang Dynasty, it is also a terrifying yield." Such a huge yield, plus the ability to grow the rest of the grain...... Not only is it a full stomach, but it is not difficult to have surplus food in addition to a full stomach. ”

Xue Lang said: "Li Shangshu's inference is correct, but it is also necessary to take into account the factors such as planting conditions and technology, if it is in a high mountain area, the land fertility is weak, and the cultivation technology is backward, I am afraid that it will not be able to achieve the current yield, and at that time, it is necessary to grow a few acres in these areas." ”

Li Gang said: "Even if there are a few acres of variety, it is enough for a few families to eat. ”

Xiao Yu continued: "In this way, at most, in five years, there will be a question in front of you. ”

Xue Lang had already expected it and said: "The problem of overcapacity!" ”
