If, as Yang Song said, the yield of potatoes and sweet potatoes is really abundant, how to plant them is indeed a secret.

"Can potatoes really be a staple food and a dish?" Zuo Yu has a lot of eyes in the city.

Yang Song nodded: "yes, it can be steamed directly, fried and roasted. As long as it is not eaten raw, it can be eaten. It's delicious."

Zuo Yu doesn't believe it very much.

He is the commander and naturally skeptical of everything.

If everyone followed suit, Whitewater would be gone.

Yang Song added, "you can ask the chef of Baifeng pavilion to teach the cooks in the military camp how to cook potatoes. There are simple methods and exquisite ones. They are very delicious."

"How long can I learn?"

"It should be tomorrow. It's not difficult."

Potato cooking is very simple. The cooks in the military camp can pick the girder to cook the meals of tens of thousands of people. It's too easy to learn a potato dish.

"Tomorrow?" Zuo Yu was surprised.

"Basically, I'll watch it once. Just in case, I'll keep them to practice in Baifeng Pavilion and let them come back after inspection. I think it's the slowest for them to come back to the camp tomorrow night. However, it takes about four days to learn how to make noodles. If you want noodles to be convenient for storage and transportation, you have to leave enough time for drying in the sun. I have to watch them do it again."

"In other words, it only takes five days to learn all?"

Cook for one day and make noodles for four days.

"No, it's four days in total. Just put the vermicelli in the air and learn to cook potato dishes in your spare time."

It's too simple.

Zuo Yu asked, "what is the yield of potatoes?"

Yang Song: "the yield per mu is about 3000 to 5000 Jin."

"What are you talking about?" Zuo Yu suddenly patted the table and stared at Yang Song. Jin Gang was angry and wanted to break Yang Song into pieces.

Yang Song has long been very experienced in covering his ears: "you heard right, that is, the yield per mu is 3000 kg to 5000 kg, mainly because the land is not good. If it is a fertile world, selecting excellent seeds can produce 6000 to 8000 kg per mu. Is this a thing?

Don't be shocked. When I told the magistrate and county magistrate, they were all so surprised. "

Zuo Yuqiang controlled himself without holding a knife against Yang Song's neck and said calmly, "do you know what crime it is to deceive the coach?"

Yang Song: "I don't know, but I guess it's similar to beheading. Xiaoqingshan still has a few acres of land confiscated. Take someone to verify it."

"Call the troops, take the scale and go at once." Zuo Yu actually wanted to go in person: "you too."

Yang Song was also taken.

Fast horse, and bring all the good players.

The sunny side of xiaoqingshan is almost full of potatoes and sweet potatoes.

"Be careful, don't trample on the field." Zuo Yu got off the horse first, asked someone to tie the horse away, went down to the ground in person, stared at the seedling stem exposed in the field and said, "but it grows underground?"

Yang Song followed and pulled out some sweet potatoes: "this is the sweet potato field."

The sweet potato stalks were pulled out and connected with four or five. They were not small.

Yang Song pulled down one and a worker immediately handed over the bucket.

After washing and breaking it off, the sweet heart sweet potato takes a mouthful of honey.

"It's really a mountain sweet potato. It's delicious!" Yang Song ran so far on his horse that he was just thirsty.

Zuo Yu stared at him and bit again and again like eating snacks.

Yang Song finally found it and handed him half: "try it."

Zuo Yu doesn't pinch. He doesn't need much effort. The crisp taste is like fruit. It's rich in juice. It also cushions his stomach to quench thirst. Most importantly, it's sweet.

How expensive is sugar? Ordinary people in Baishui city are only willing to weigh one and a half catties of sweet mouth to replenish their body during the new year's festival.

In the cold north, sugar can best supplement physical strength.

Three or two people ate half a sweet potato. Zuo Yu carefully weighed the weight of each sweet potato and squeezed it hard. It was very porcelain and the weight was not low.

Zuo Yu didn't have to do it himself. He squatted on the ground and picked up half a basket of sweet potatoes.

Weigh the weight.

"No less than 20 jin."

He didn't even move his steps. The sweet potato was planted intensively underground.

"Twenty Jin, twenty Jin, ha ha..."

Zuo Yu burst into tears excitedly. The yield per mu can definitely reach more than 1000 Jin.

This mountain area can only be regarded as a field below the middle level. There is no shortage of fertile fields in Baishui city.

With such grain output, civilians will no longer starve to death, and soldiers will no longer have to tighten their belts.

Before soldiers and horses move, grain and grass go first.

Whether it is war or defense, food is crucial.

Zuo Yu's biggest trouble every year is to urge the Ministry of household for food. Those bastards have never given them all, nor have they given them on time.

If self-sufficiency.

"How can I eat sweet potatoes?"

Yang Song: "it's sweet. It can be used as a staple food, eaten raw or boiled porridge, or steamed and roasted. It's convenient for storage. If you want to make vegetables, you can make sweet potatoes into vermicelli."

"Can sweet potatoes also be made into vermicelli?"

"Of course."

"Where do you grow potatoes?"

"Opposite."

Zuo Yu hurried over and dug with her hand.

Potatoes are buried deeper and heavier than sweet potatoes.

"Can you eat it directly?"

Yang Song choked: "no!"

"Potatoes can't be eaten raw. They must be cooked."

Yang Song ordered people to steam potatoes, roast potatoes, shred and fry potatoes, and stew potatoes.

"Get some more sweet potatoes by the way."

Soon, Zuo Yu tasted it.

"Delicious!"

Everything is delicious, nothing is not delicious.

The soldiers who followed were given steamed sweet potatoes and baked potatoes.

Sweet potatoes are more sweet after steaming. Potatoes are burnt and full.

Zuo Yu's eyes were shining at Yang Song.

"What do you want?"

"How to plant?"

Potatoes and sweet potatoes can survive on barren mountains like xiaoqingshan. If they are planted in good fields, the yield will be higher.

Zuo Yu made up his mind that Yang Song must tell him the planting method, or he would lift the knife.

"It's very simple. Just leave your own soldiers and learn from them. You're about to plant the next wave."

Yang Song didn't care about his style. Zuo Yu was fascinated: "do you know what these mean?"

The national economy and the people's livelihood, as long as potatoes and sweet potatoes are successfully planted, no one may be so easily starved to death after summer.

With food, the combat effectiveness of the Daxia army has also been guaranteed.

Yang Song is a businessman. This is definitely a business opportunity.

At least it can help Yang Song become the richest man in a country.

As long as money can be used, Yang song can be below one person and above ten thousand people.

"Of course, but I'm not interested." Yang Song said with a smile, "general Zuo may not know me. Compared with businessmen, I prefer to be a successful cook."

His job is to cook, and being a boss is just by the way.

Zuo Yu doesn't understand very well. How can anyone so easily refuse to break heaven's wealth and unparalleled power?

Yang Song said, "maybe if I explain this, general Zuo will understand that you are a general and a scholar. If the world is peaceful and the ruling and opposition are clear, I'm afraid the general would prefer to be a teacher, teach people to read and practice martial arts."
