Nearly 10000 mu of potato experimental field is about to have a good harvest. Looking around, the mature leaves are feathered and green, like a group of flying birds about to spread their wings.


    After rough calculation, it is estimated that the harvest will be 30 million jin, enough for the people of Chang''an City for more than a year and nearly two years. People will not have to worry about having enough to eat this year. On the night before the harvest, Tang Hao stood by the ridge and looked at everything with joy.


    But it was difficult to digest so many starch pimples all at once because of the sudden large quantities of potatoes and the lack of advanced frozen storage technology.


    Maybe if you look here, you will say that you can sell it directly to Tubo and Persia, and earn some foreign exchange. However, in that era when there were only ox carts and ships for goods transportation, the product did not have twice the profit, and Datang merchants would not think of shipping this product hundreds of miles away for sale.


    Moreover, fresh potatoes have more water, which is inconvenient for long-term storage and transportation. Then Chang''an city will produce and sell itself.


    The royal nobles in the palace subscribe to thousands of kilograms in one palace, and most of the output can be consumed at once. For the common people, potatoes have just begun to be planted in Datang. In order to promote food, the purchase price is only one-third of that of rice, beans and wheat.


    In order to facilitate the purchase, Tang Hao issued a bill of lading to each shop in the general''s house. The buyer now fills in the number of potatoes purchased, pays on site, and then takes the bill of lading to the potato experimental field in the suburbs.


    At first, everyone dared not eat it. They had never eaten it before. What should we do in case of food poisoning after eating it? But soon, with the advantages of easy cooking and full flavor of potatoes, the popularity of Chang''an people for this new food increased day by day.


    On a sunny day, after placing orders and paying in the city, the people happily pushed their cars to the Tang''s experimental field in the suburbs to pick up potatoes with delivery bills.


    A large round potato was placed on the cart, and the people who picked up the goods were filled with joy, as if the cart was not pushing potatoes, but lumps of gold.


    Tang Hao''s father-in-law Li Jing and his mother-in-law Hongfu''s Palace also subscribed for one million jin. It could have been sent directly to the house, but Li Jing wanted to come to see his son-in-law''s experimental field himself. Hong Fu also wanted to come out and see the excitement.


    The couple dressed up very skillfully that day. Walking on the main road near the field, behind them were the young young students of Li''s house, one by one pushing carts to transport goods and materials.


    Looking at the people who received the potatoes in front and the round potatoes piled up on the car, Hongfu couldn''t help but say first: "our family subscribed for a million kilograms of this thing, that is, more than 200 yuan, not more money but less money." then she glanced at the oncoming potato car.


    Then Hongfu said to Li Jing, "but our family can''t eat all this in a year, even if it''s every day."


    Li Jing suddenly realized that yes, even in this year, Li''s house will eat potatoes for three meals. They will be the staple food. They will not be digested until the beginning of next spring.


    As one of the founding fathers of the country, he witnessed the tragic scene of no food to eat and starvation victims everywhere in disaster years. Now there is a bumper harvest of food, but the rations are ruined because they can''t eat up. Will God forgive them for this waste?


    Thinking of this, Li Jing regretted that she was hot headed for a moment and subscribed so many at one time, but she came all the time. Let''s move back to the Palace first.


    The people were happy that they had solved the problem of rations at once. But for princes and nobles, they can''t digest it at the dinner table. Li Jing, the father-in-law, looked at the huge potatoes on the table and wanted to cry without tears.


    It''s a great sin to waste food. Since the founding of the capital Chang''an, Datang has not encountered such a bumper harvest of potatoes and excess food as today. In the famine years, potatoes were really precious, but now they have enough food and clothing. Even if they are fragrant, they can''t stand to eat every meal. Eat every day and eat without rest.


    Nowadays, not only the National Treasury is full of potatoes, but people also have sufficient stocks in their own warehouses.


    Of course, as a potato experimenter and planting initiator, Zhenguo general Tang Hao personally took the lead in subscribing 3 million kg in the face of the current bumper harvest.


    Back home, the backyard of the Tang family was full of potatoes. Princess Changle was playing with her little son. Li Wanqing asked his servants to move most of the potatoes into a dry warehouse in the backyard.


    Seeing Tang Hao back, Li Wanqing happily said to the officials, "husband, your planting method is really good. We have saved so many potatoes this year. We don''t have to worry about rations until the beginning of next spring."


    Tang Hao smiled and said, "my lady likes it so much. From tomorrow on, in the morning, in the evening, including your snacks and snacks, what do you think?" obviously, Tang Hao is also a little difficult to face the sudden harvest.


    Princess Changle stood up, wiped her hands and said to Tang Hao, "this is your son-in-law''s merit. You have a bumper harvest of food and benefit the people. Compared with the casualties on the battlefield, this is a great achievement lasting for thousands of generations."
