Lu Xianling smiled embarrassedly: "Lord Hui Qincha, I'm too excited, I'm a little out of shape." I was overjoyed for a while, and I asked for forgiveness. ”

"I think you're a first-time offender, pay attention next time." Lord Qincha Zhang said in a deep voice that in fact, he made the same mistake as Lu Zhixian when digging sweet potatoes.

After digging out the sweet potatoes, there are less than three points of potatoes left.

Begin to weigh the land, and take a large scale from the yamen to pay the grain tax. There is a small official of the yamen, who is responsible for careful recording and supervision to prevent repeated weighing.

After half an hour of weighing, the yield of sweet potatoes per acre has reached 6,800 catties. Rice is abundant in the area. The yield of rice per mu can reach 200 catties, which is already very high. But these sweet potatoes can reach 6,800 catties. Even if it is dried and shrunk ten times, there are more than 600 catties!

The only deficiency may be difficult to save, but a solution to it can be found. Especially in the north, put it in the cellar and eat it again the next year.

High-yielding sweet potatoes and potatoes are right in front of them. They saw them being dug out of the ground.

This must be auspicious from the heavens!

Two at a time!

Lu Xianling cried with joy. If high-yield sweet potatoes can be successfully promoted in the north, even if the yield is only half, more than 3,000 catties per mu, it can feed a family.

This high-yielding crop first appeared under his rule. Lu Xianling was willing to be a witness and played to the court together. He'll be rewarded too.

Soon, every acre of potatoes was dug up. The number of potato piles is large, and the visual measurement is not less than the yield per mu of sweet potatoes.

Lord Lu was very excited

Zhang Zhao nodded and said, "When the potato yield is good, I will go back to the capital."

The next officials of the yamen were also very excited. It was an honor for them to be able to participate in such a grand event. Soon, the yield of potatoes per mu was as high as 5,600 catties.

Everyone was shocked and happy to get such a result.

Qin Cha Zhang Zhao was also very happy. He took out two hundred taels of silver on the spot and handed it to Shen Yunxi, "Mrs. Tian, this is what the lower official promised just now, the yield per mu reaches more than 5,000 catties, and those who come to help will be rewarded with five taels of silver, take it and distribute it to everyone, and the rest will be used as today's meal money." ”

Shen Yunxi did not refuse, but took it. "On behalf of the villagers, thank you Lord Zhang!"

Qin Cha Zhang Zhao waved his hand, not wanting to continue to be polite. "Mrs. Tian, tell me how to grow sweet potatoes and potatoes."

Shen Yunxi took the sweet potato, pointed to the place where the sweet potato had flower buds, and said, "Lord Zhang, keep these places with flower buds, make them into several pieces, and bury them directly in the soil." It is best to make vegetable furrows, which are convenient for fertilizing on the one hand, and drainage and watering on the other. The branches on the sweet potato seedlings can be pinched off and planted directly on the ground. Potatoes are grown in a similar way to sweet potatoes, but the branches should not be cut off, and the excess should be pinched off so that the fruits in the ground can grow larger. ”

Qin Cha wrote it down, and then said to Lu County Order: "Lu County Order, the sweet potatoes of Shen Yunxi's lady's house and the sweet potatoes of Qianlihua Village, except for keeping seeds, are all bought, properly preserved, and ready to be transported to the north as seeds."

Lu Xianling thought for a while and asked, "Lord Zhang, how much do you charge for sweet potatoes?"

Thinking of the huge impact of the popularization of this seed, Qincha Zhang Zhao thought for a while: "Let's give five wen and one catty." That's just the price for the first year. It won't be so expensive in the future. ”

Wuwen a pound is not as expensive as 30 wen a pound of tomatoes and peppers, but the yield per mu is large, the purchase price is too expensive, and the imperial court needs to spend too much money and the pressure is too great.
