In this era of low yield, almost every family has thousands of acres of land, and the output of refined grains is limited, so it is necessary to supplement some coarse grains. Now that sweet potatoes and potatoes, two crops with such high yields, can be made into vermicelli to improve the shelf life, the temptation of potatoes and sweet potatoes is not small for the families of the powerful who are accustomed to accumulating food.

Whether ancient or modern, food security is related to strategic security, and this truth can be explained in both the country and the family. The sage has these two things in his hands, and when he promotes them, he can do a lot of articles. Especially in the past two years, the imperial court has fought a lot of battles passively or actively, and military rations will always be a headache for the imperial court.

If the high-yield and easy-to-grow sweet potatoes and potatoes can be used as a supplement to military rations, they will certainly be able to greatly alleviate the pressure brought by raising military rations to the imperial court. This is the benefit of the saints alone, and the saints will pay attention to it.

Xue Lang said: "When the sage comes back, I plan to make a sparse performance, and suggest that the sage build a huangzhuang in Henan, Hebei, Shandong and other places, and use it exclusively to grow potatoes." When I was in the Ministry of Civil Affairs, I specially checked the climate of these areas, and with the geographical location and climate of these areas, it is completely possible to grow two crops of potatoes a year, and even if the yield of the second season is not as good as that of the first season, half of the yield should be reached. ”

Princess Pingyang was shocked, and immediately asked, "Is this true?" ”

Xue Lang seriously promised: "Nine out of ten are stable!" ”

Princess Pingyang silently calculated for a moment in her heart, and said happily: "If you can really plant two crops, the yield per mu does not need to be much, and if you can harvest more than 4,000 kilograms per mu of land a year, it will be enough!" ”

Speaking of this, he paused, glanced at Xue Lang, and said, "If that's the case, tomorrow I will send people to these places to buy land and build farms!" ”

Xue Lang smiled and asked, "Why do you want to accumulate grain?" ”

Princess Pingyang was stunned by the question, and asked rhetorically: "Didn't Youyang propose to increase our strength and be beyond the crown prince and the king of Qin?" ”

Xue Lang looked directly into her eyes and said slowly: "Therefore, there should be no accumulation of grain." ”

Princess Pingyang's eyes flashed and asked, "How do you say this?" ”

Xue Lang said: "Since Jianling has relieved you of the military power, then don't touch it again, instead of accumulating food to make people taboo, it is better to do something else." My suggestion is that you don't need to accumulate more food, just generalize it. If you want to plant cotton on a large area, you should not grow grain. In my opinion, two or three acres of sweet potatoes are enough, and the same is true for potatoes. ”

"White Stacked ......"

Princess Pingyang was thoughtful. Xue Lang nodded and said: "Cotton is very versatile, making quilts, spinning fabrics, no matter what, at present, it is our unique technology. Since it is unique, the initiative is on our side. Even if the cotton planting technology is publicly promoted in the future, we occupy the pioneer and technical advantage, and the market share is certainly not comparable to others, and we also have the initiative, and the room for operation is greater, and the action will be more transcendent. ”

Princess Pingyang suddenly, her eyes lit up, and she looked at Xue Lang's eyes with a smile, and slowly bowed her head: "Youyang is right, I thought about it before." Growing cotton...... What is the best way for Youyang? ”

Xue Lang rubbed his hands and said happily: "I also studied the information when I was in the Ministry of Civil Affairs, which area is suitable for growing cotton, I already know in my heart, come, I'll tell you!" ”

Xue Lang circled out the area suitable for planting cotton, and when it was over, Xue Lang said with regret: "In fact, the most suitable area is the Longyou generation, but now it is not the territory of our dynasty, and when the Turks are defeated and the land is divided, remember to circle a little more, build a big cotton plantation, and strive to be the first master of cotton products in the Tang Dynasty!" ”

Xue Lang's conclusive appearance made Princess Pingyang laugh and said, "Youyang actually despises the Turks so much? Are you so convinced that our dynasty will be able to destroy the Turks? ”

Xue Lang nodded and said, "This is the general trend of the world!" It will definitely be extinguished, but sooner or later! ”

Princess Pingyang looked at him with a smile, noncommittal, and only said, "Then I'll wait and see!" ”

After talking about cotton for a while, Xue Lang remembered something and asked, "How is the library being prepared?" ”

Princess Pingyang said: "The building has been built, and now it can be opened when enough books are raised." ”

Xue Lang nodded, with the current level of printing, it will indeed take a little time to raise enough books to open a library. The two talked for a while, and Changjian came to report that the meal was good and it was time to eat!

Xue Lang personally ran to bring the food in, put it on the desk, and ate around the desk with Princess Pingyang. Of course, I'm afraid that Princess Pingyang won't get used to it, so the meals are still separated, just a table.

Today's main dish is a large plate of chicken, the main food is steamed buns, and it is paired with three side dishes, which is more than enough for two people to eat. Princess Pingyang picked up the green peppers in the large plate of chicken with chopsticks: "This is the pepper that Youyang planted before?" ”

Xue Lang: "Yes, last year there were few seeds, and I didn't dare to eat green peppers, I only ate dried peppers, and this year I left enough seeds, but I can eat them, this variety of green peppers is not too spicy, you try." ”

Princess Pingyang nodded, took a bite, and then ate, her face turned red, and she covered her mouth and beckoned to Xue Lang, Xue Lang hurriedly handed over a glass of water and looked at her with a smile: "The first time I eat it, I may not be used to it, is it too spicy?" ”

Princess Pingyang swallowed the water and said, "It's a little uncomfortable, it's different from the taste of dogwood, and the spicy taste is purer." Remember to share some of this year's seeds. ”

"Okay!"

The two of them talked and ate at the same time, not talking much, but they did not strictly abide by the rule of eating and sleeping silently, but they were also happy.

With the base soup of the big plate of chicken, Xue Lang ate steamed buns, and also ate a lot of chicken and potatoes, Princess Pingyang was not far behind, seeing that she ate slowly and methodically, the chicken bones piled up on the plate in front of her were not less than Xue Lang.

Xue Lang looked at her with a smile and said with a smile: "After we get married, why don't we make a big table and eat like this in the future, okay?" ”

Princess Pingyang glanced at him and nodded: "But!" ”

After nodding in agreement, he said, "Have you ever thought about how to place the home furnishings?" Do you have any suggestions? It is better to draw a picture while the time is still early, and let the craftsmen make it, so as not to have to restructure it themselves in the future. ”

Neither of them is a twister, and they are not shy about talking about it. Xue Lang immediately said: "Okay, I'll draw it when I have time these days, and then let's discuss it and choose a style that we both like." ”

Talking about family life, it wasn't until it was about to get dark that Princess Pingyang left from the small door and went back. Xue Lang came back after sending people back, thinking of her smile, he couldn't help but curl the corners of his mouth, and when he was interested, he took out his drawing paper and brush, and simply sketched out many pictures of home furnishings.

When Xue Lang happily painted a picture of his home, the sage also announced that he would end the summer vacation early and return to Chang'an from Renzhi Palace.
