After the eldest grandson gave Li Yuan a salute, he turned his face to look at the peddler, "Dabao, let's start now, shall we?" ”

"Hmm!" The peddler forced a smile at Li Yuan and the ministers and said, "Now I have to ask the crown princess to show you the solution of the way of poor clothes!" Everyone, please take a look! ”

The eldest grandson walked to the various tools brought by the eunuch door, and first grabbed a handful of cotton, "Your Majesty and an adult, this is the cotton brought by Niu Daochang, and I also have it in Datang, but our name is Bai Diezi, and now I will demonstrate Niu Daochang's solution one by one!" ”

After saying that, the eldest grandson took off the seeds in order, spun and weaved the cloth, because each link was just a demonstration, so it didn't take much time, and after everyone watched the demonstration, the vendor took the cloth she had woven before from the eldest grandson and presented it to Li Yuan, "Your Majesty, please see, this is the cloth spun by the crown princess herself, you can touch the feel now!" ”

Li Yuan stretched out his hand and wiped a handful of the cloth pulled out by the vendor, nodded with satisfaction, and the vendor knew that he had passed this level, and then held the cloth and explained to everyone, "As you can see, Poor Dao deeply observed the folk customs of my Tang Dynasty when he received His Majesty's will, and found that in addition to the princes and nobles, the people are all coarse linen clothes, and everyone knows that the texture of this hemp cloth is rough, and it is very uncomfortable to wear, so Poor Dao thought of using this white stack instead of hemp to weave cloth, It is used to improve the clothing habits of the people of my Tang Dynasty, and now everyone can feel the difference between cotton and linen! ”

After saying that, the vendor held the cloth around the field again, and all the ministers also felt the delicacy of the cotton cloth with their hands, and nodded after feeling it!

The hawker is very satisfied with the reaction of the crowd, and if you are satisfied, it means that we have passed this level, but it is over, and we want to live perfectly" Okay, everyone has felt it, and they all roughly understand the difference, so now I will tell you some things, in addition to making cloth, the most important thing is that it has a miraculous effect in keeping out the cold! ”

"Now the people use sacks wrapped in catkins to keep out the cold, and the effect of keeping out the cold is very poor.

"Then this time, not only to introduce cotton to you, but more importantly, to improve the weaving efficiency of Datang, please look at this loom, its appearance can make a woman weave two pieces of fine cloth in one day, I think with this efficiency, as long as the mother-in-law is not lazy, then the whole family will definitely not have a bare stomach, right?"

After the hawker finished speaking, everyone laughed together, and even the eldest grandson couldn't help but laugh! The peddler turned his head to look at Li Yuan again, "Your Majesty, this level is considered poor, right?" ”

Li Yuan looked at the reactions of the ministers, it seems that the things brought by the hawkers this time are still relatively convincing, and he can't go against these people, "Okay, even if you pass this level, what next?" ”

The vendor handed the cloth to the maid beside the eldest grandson, clapped his hands, and said, "Please also ask the prince to call someone!" ”

After a while, a few eunuchs from Li Er's Mansion moved two large storage boxes in pairs, each box had two plants, but the difference in appearance was too great, one inside was like the soft stamping of the pillar after Ai Ai, and the other was straight and tall than everyone before!

Li Yuan, including some ministers, saw these two things for the first time, and after the eunuch put down the two storage boxes, Li Yuan couldn't help but be curious and walked down the dragon case to the edge of the box to look, and also used his hands to compare the height of the two plants back and forth, and the confusion in his eyes became heavier and heavier!

The peddler hurried over, "Your Majesty, these two plants are dedicated to the Tang Dynasty by me, and they have been planted in the prince's house, and they were ordered to dig up completely for today's examination, but because of the late planting time, this thing is not fully mature, but it can also be eaten, and it will be displayed for Your Majesty now!" ”

"Here's a few helpers, get this thing out carefully!" As soon as the hawker finished speaking, the three fools of Chang'an rushed to come over to help, and the hawker hurriedly drove him away.

In the end, the eldest grandson pouted, and the little palace maid behind him came over and carefully removed the soil in the storage box little by little, which felt like archaeology, but it was good that the whole sweet potato root system was preserved, and when the last complete sweet potato was brought out by the vendor, everyone found that there were three to four arm-thick lumps hanging under each seedling, and those who had eaten it knew that this was the fruit of this thing!

The vendor looked at the sweet potato, because the time was short, only the thick arm of the sweet potato, the length of the sweet potato, if you plant it earlier, the time is longer, it is estimated that it will be more impactful!

The vendor pointed to the sweet potato and said to Li Yuan, "Your Majesty, this is the sweet potato brought by the poor road, which can be eaten raw, steamed, or dried and preserved, and the normal yield per mu is about fifty stones!" ”

Hearing this, Li Yuan, who was observing carefully, also stared at the size of a cow's egg, and his body shook irrepressibly, and waved his hand, "Come on, take it!" “

There was a eunuch who trotted all the way back and forth to hand a scale to Li Yuan, and was just about to help weigh it, Li Yuan waved his hand and drove the person away, and he carried the scale and motioned to the vendor to put the sweet potatoes up, and the hawker dragged down a few sweet potatoes and put them on Li Yuan's scale, and the old man took the scales back with a clear door, and the action was like the city management of many years of actual combat!

The old man put the scale to a position of about three catties, but don't forget that Tang weighed it sixty grams, and it was about four catties in modern times, looking at the high raised scale rod, Li Yuan compared the size of the storage box again, "Dabao, I'm afraid this thing can be planted more than 3,000 trees per acre, right?" ”

The hawker has seen the importance of agriculture in the ancient emperor, like us, the slogan shouts to attach importance to agriculture, but in addition to the annual subsidy of more than 80 yuan per mu, who has seen other benefits of being a farmer, you can now find a random leader to ask how many catties of seeds are needed for an acre of wheat, it is estimated that it is difficult for someone to answer!

"Your Majesty is aware of everything, this thing can indeed be planted with 3,000 to 5,000 plants per mu, and the harvest is generally between 30 and 100 stones!"

Li Yuan himself estimated that what the vendor said was true, "Well, Dabao has a heart, so tell me why you have this thing and contribute this thing next to it?" ”

The vendor has a toothache, isn't this Nima because he doesn't know what you love! "Back to Your Majesty, the reason why I offered this thing next to me is completely because of the vast territory of the Tang Dynasty and the different terrains in various places, so Poor Dao got two kinds of plants to adapt to the climate of different regions!"

Li Yuan nodded, "It should be so, then can this tall one also produce fifty stones per mu?" ”

The hawker wiped his sweat, "Your Majesty, this is not good, this can only produce seven or eight stones, but it is better in taste, and eating the two alternately can also increase the happiness of the people!" ”

Li Yuan nodded again, "Dao Chang is merciful, I thank you for the thousands of people in the Tang Dynasty, it doesn't matter if you don't take the next exam, the ancients know the etiquette, this people can eat and drink enough, I feel honored to do anything, Dabao I really thank you!" ”

Hawker Smecta, this is the end? This is too, no, we still have so many things that haven't been shown, "Don't, Your Majesty, I still have a lot of things that I haven't taken out, since I have passed the exam, let's watch more and not suffer a loss!" ”

Li Yuan was amused by the hawker's words, and he hadn't seen anyone who was in a hurry to get on the pole to find a ballast for himself, "Okay, I see that you kid is afraid that I won't let you preach, you can rest assured that I still speak a word, but since you have said it yourself, then what good things can be brightened outward, and let me open my eyes!" ”

Now that the school examination has passed, the hawker has no psychological burden, and he arched his hand at Li Yuan with a smile, "Your Majesty, just take a look!" ”
