An hour later, North Mountain.

As the carriage stopped and the door opened, Zhou Heng jumped down first, stretching his arms and legs.

Although the carriage was warm and comfortable, it was still uncomfortable, and it seemed that the carriage should be designed with a few comfortable sofas, otherwise it would be too uncomfortable.

Liu Xiuer and Su Xiaoxiao saw that the car stopped, but they just raised the curtain of the car window.

"Second brother, why don't I take Miss Su to Qingyun, and we'll go to the kitchen to prepare a spicy fish pot for you in a while."

Zhou Heng nodded, pointed to Zhuangzi and said:

"Go, Qingyun is on Zhuangzi, as soon as you ask where the white girl lives, they will know."

Liu Xiu'er and their carriage turned around and headed towards Zhuangzi at the foot of the mountain.

At this time, Liu Renli jumped down, and this time, Zhou Heng found that Liu Renli had changed a lot.

Although he is still persistent, the whole person is much calmer, which is what Zhou Heng is more pleased with, and being able to hide things in his heart is the basic skill of being an official.

Along the way, Zhou Heng had already told Liu Renli about what Beishan had done in the past few days, and what he planned to do in the future, including how to use everything on this barren mountain, and told him everything, of course, including the two new crops.

Standing on the mountainside of Beishan at this moment, looking carefully at the past, this piece of workshop is scattered, very spacious and tall, making him believe that it was built in two months, which is simply unbelievable.

Thinking of Zhou Heng's method of repairing the ditch, Liu Renli's eyes widened, he believed that Zhou Heng must have a way to dig on the frozen soil, and the wide road in front of him, as well as the workshop, is not much more difficult than digging a ditch.

He turned his head to look at Zhou Heng, "Second brother, tell me, what method can be used to dig on the frozen soil?" ”

Zhou Heng smiled, pointed to a place where there were personnel and said:

"Seeing is believing, let's go and see."

Although Liu Renli was in a hurry, he also knew that he still saw the most effective effect, so he hurriedly quickened his pace, and Zhang Huaiyuan helped him to follow behind Zhou Heng.

Several people moved quickly, and when they came to a construction site that was being built, all the construction people were wearing rattan hats like melon skins, with thick turbans wrapped in hats, and their bodies were also very thick.

Aren't the gloves on your hands cold when they are finger-barre?

However, in an instant, Liu Renli felt that the temperature of the construction place was a little higher than the place where they had just stood, and he took out his hand and did not feel how cold.

Liu Renli looked at it, and then found the problem, it turned out that the surrounding area was surrounded by thick cloth, and there were several large iron barrels in the middle, which seemed to be coal, and the temperature could be felt from a long distance.

"Is it because of these fences and the iron bucket heating?"

Zhou Heng shook his head, "They are not too cold during construction, so they invented these things, you see that there are handles on the edge of the iron bucket, and you can take them wherever you go, even if they burn, they will not be hot."

As for the frozen soil on the surface, the people on this Zhuangzi have thought of a good way, big brother, look here. ”

Saying that, Zhou Heng walked to the corner of the fence, where there was thick grass on the ground, and there were some dead branches thrown around the circle, Zhou Heng pointed to this pile and said.

"In the days before the road was built, it was much colder than the current weather, so they would lay a layer of dead grass and branches on the place where the road was going to be built, and then light it and burn it for half an hour, and the frozen soil could be dug down to half a person's height, and I think most of the ditches needed by the eldest brother should be at this depth."

Liu Renli nodded, and his hand gestured to his waist.

"In the county on the west side, the deepest is waist-deep, and the two counties on the east side can be reached to the chest, even if it is connected to the river, it only needs to be more than one person deep, so it can be burned twice, right?"

Zhou Heng laughed and kicked at the dead branch.

"These things can be taken locally, but the places that need to be excavated need to be cleared of snow, otherwise they will all be extinguished before they burn."

Zhou Heng remembered that the permafrost around Beijing, Hebei Province seemed to be about 85 centimeters, but in fact, as long as it was burned through, the permafrost could be thawed at one time without delaying the construction at all.

The more Liu Renli thought about it, the more he felt that this method was cost-effective and easy to implement, as long as it was dug to a suitable depth according to the topography of each county, even if it was flooded again next year.

"Don't say it, your method is really good, let's go back to each county and start implementing it."

Zhou Heng finally breathed a sigh of relief when he saw Liu Renli, and then he said with a smile:

"Big brother, don't worry, since half of your worries are solved, how about going and seeing the two new crops I planted?"

Liu Renli smiled and patted Zhou Heng on the shoulder.

"Let's go, let's see what you've got."

Zhou Heng looked mysterious, and said with a glint in his eyes:

"Let's put it this way, I'm already cultivating in the greenhouse here, as long as the outside temperature is suitable for planting, you can move outside, both crops are crazy grown, and the harvest is enough to scare you."

Liu Renli felt that Zhou Heng was exaggerating, but he didn't want to hit Zhou Heng, and followed him towards a gentle house.

As soon as he was about to enter, Liu Renli found a difference, this is not an ordinary resident's house, the north side is a high wall, the south side is half shorter, and the roof is paved with a whole glass board.

From the outside, you can see that there are ridges of land inside, and there seem to be green leaves in the middle.

This time, without Zhou Heng's urging, Liu Renli took a step in an instant, saw the door on the side, and directly opened the door and walked in.

The temperature in the warm room in an instant made Liu Renli stunned, not to mention spring, there was a feeling of early summer, it was too hot, and his body was sweating instantly.

Look at the few people in the conservatory, some of them are wearing sleeveless shoulders, barefoot and holding trouser legs, standing in the ditch, holding earthworms in their hands.

Seeing Liu Renli and Zhou Heng coming, he hurriedly threw away the earthworm in his hand and wiped his hands clean on both sides of his pants, then shouted with a smile.

"Don't do it, you guys are coming."

With a shout, everyone straightened up and looked over this side, regardless of whether they were disheveled or not, and ran over barefoot.

Even in such a joyful moment, I did not forget to look at the ditch and carefully bypass the green seedlings on the ground.

Zhou Heng looked at them and smiled, "I saw the green in the greenhouse from a distance, I didn't expect you to really grow these two things." ”

After searching in the crowd, Zhou Heng saw Laifu coming from behind.

Laifu waved to the crowd, "Okay, the son is here, just work hard, grow these two things, you can't miss your benefits, forget the red envelopes for the New Year?" ”

As soon as these people said this, they were even more grateful, and some immediately wanted to kneel down and kowtow, but Laifu was annoyed, and immediately shouted:

"Stop for me, go out and kneel, whoever steps on the seedlings is careful of the dog's head."

Such a shout was really very effective, and these people all waved at Zhou Heng, and then went to work.

However, seeing that Rifle said the same, Zhou Heng was still very satisfied, he didn't need how smart the manager was, as long as the execution was first-class, he could also bring out a good team.

Looking at the green seedlings on the ground, Zhou Heng can now conclude that all the potatoes planted in this greenhouse are potatoes.

"Golden potatoes grow well, I didn't expect them to sprout so quickly."

Laifu squatted down and said carefully:

"It's not planted on the same day, you see there are signs on it, some are planted with germination, some are planted without buds, some are planted after cutting and drying for a little day, although those that are cut and dried for a day are planted two days later, but the growth is faster than the previous planting."

Zhou Heng came to his senses and looked at Laifu seriously, he just knew where this thing was the seed and how to plant it, but the detailed process was really unclear.

I really need this kind of down-to-earth person, who can test in detail and get first-hand information.

Zhou Heng looked down at the two-inch-tall seedlings above the ditch, not to mention a few days of hard work, this thing grew so fast, but it was obvious to see the traces of the small pits in the roots, it had been watered here, but he was not good at it.

"Is this watering?"

Laifu smiled, "I pondered, this thing is so precious to be cultivated well, so I found bran to soak in water, and then watered, I didn't expect the germination rate to reach ten percent, and the seedlings grow very fast, I just don't know when this golden potato will be harvested." ”

Zhou Heng thought about it, and remembered that it seemed to take three months to plant potatoes in later generations, and some early-maturing varieties would take less than three months.

"I don't think it's okay for three months."

Liu Renli looked around, and then leaned closer and asked:

"Tell me, what the hell is this stuff?"
