Old Village Chief Zhu squinted his eyes and didn't say anything for a long time, he glanced at the copper coins and bamboo chips scattered on the table in the pit, and suddenly said: "Zhou Laiyu, if there is anything you want to make in Guo Dalu in the future, you can just do it, if you lack materials, you and I will mention it." ”

Carpenter Zhou was stunned, he knew that when Old Village Chief Zhu called his full name, it meant that he was speaking very seriously, and he thought for a while: "Medium." If that drip irrigation is really good, I'll be a lot more leisurely, so I'll accompany the Guo family kid to toss. ”

After sending off Carpenter Zhou, the old village chief Zhu hurriedly went out and went to the ancestral hall in the center of the village, and then returned to his home.

Early the next morning, without the old village chief's greeting, the villagers hurried to the kudzu grass field, continued to build bamboo pipes, and laid all the kudzu grass fields before the watering time arrived.

"Water!" With the shouting of the old village chief Zhu in his long voice, several of the strongest young men in the village stepped on the waterwheel in a hurry, and there was more than one waterwheel, and four waterwheels were erected along the side of the stream, and the bearings and nails of the waterwheel were all made of iron.

Of course, it is not Guo Dalu's stainless steel that is used, these stainless steel have become Li Dayan's treasures, whoever wants to touch him is in a hurry, and the old village chief of the government has not had time to formally ask for it, all the iron materials are spontaneously donated by the villagers, and all the iron pots of their own homes are sent to Li Dayan.

Streams of water rushed along the nullah, passed through the trough, poured into the bamboo pipes, and moistened the arrogant kudzu grass one by one.

Carpenter Zhou and Li Da were busy in front of and back, replacing the leaking parts from time to time, adjusting the jammed gates, and apart from these minor faults, the entire drip irrigation system ran very smoothly.

When the old village chief Zhu couldn't help but announce the stop of watering loudly with a little trembling, the fields were jubilant again, and Brother Hao jumped up and shouted in front of his sister and sister: "Brother Guo's idea is really amazing! Hahaha, when I first met him in Fengshen Mountain, I knew that he was not a mortal. ”

The younger sister was also very happy: "Brother, then I don't have to use a spoon to water in the future, right?"

Brother Hao threw the small wooden spoon far away: "I don't need this Laoshzi spoon anymore!"

After the villagers were jubilant for a while, they immediately packed up their farm tools and hurried to the back mountain, where there were still their family's ration fields waiting to be cleaned up.

Guo Dalu followed everyone to the back mountain, he actually didn't care about the sorghum millet in the few acres of thin land, anyway, the food in the trash can was enough for him and Guo Jin to eat, but he couldn't stand Guo Jin whispering in his ear, the land is the lifeblood of the Zhuang family, even if Guo Jin is blind, he can't let go of the field, and has been telling Guo Dalu to clean up the fields in the back mountain.

Guo Dalu came to the back mountain, and the villagers he met greeted him warmly, many villagers Guo Dalu couldn't name them, but they felt the gratitude from the bottom of their hearts from their red faces, a villager ran over with two buckets, and said in a rough voice: "Brother Guo, I see that your family's field strength is a little insufficient, pick some people for you, you can use it, if it is not enough, pick some for you." ”

Guo Dalu only glanced at it, and it was a grin - this honest villager Baba sent it as a good thing, and it was actually two picks of dung - this is human fat!

Guo Dalu had to thank him again and again in the face of the two stinking dung--In ancient times, there was no chemical fertilizer, and human and animal feces were the best fertilizer, and in the words of the 21st century, this is authentic organic fertilizer! Even this human fertilizer is very precious in the countryside, and thrifty peasant households have to pull their own urine and urine on their own fields, which is called fertilizer and water do not flow into the fields of outsiders.

In fact, until the 21st century, when Guo Dalu sometimes accompanied his little girlfriend to the countryside to play, he could also accidentally see the manure tanks in the fields, and those large tanks were half-buried in the fields, and the manure had to be ripe in them before they could be applied.

Hey, it's ripe -- Guo Dalu turned his head to look around, but he didn't see the manure tank in the field, he grabbed the villager who kindly gave him fertilizer: "Uncle, where did you get this manure?"

The uncle said: "Where else can I get it--of course it's pulled by my own family, Brother Guo, don't worry, we have a lot of family, and we have a lot of pulls, if you don't have enough, I'll pull it for you again." ”

Guo Dalu hurriedly said: "Enough, enough--I mean, this manure is pulled down at home and sent directly to the field?"

The villagers looked at Guo Dalu puzzled: "Of course, the crops are all dependent on manure, and the harvest is good if you apply more fertilizer." Brother Guo, there are only two people in your family, Uncle Guo and you, this manure is definitely not enough for the field, the soil power of the back mountain is thin, and it depends on more fertilizer to have a good harvest. I didn't say it, in the future, our family will have all the fertilizer in your family!"

In the face of the enthusiasm of the villagers to deliver manure to the door, Guo Dalu was thoughtful, and muttered in a low voice: "It's strange, this human and animal fertilizer must be cooked before it can be used, and directly using fresh human fertilizer will burn the crops." ”

Fresh human and animal manure will burn plants, or Guo Dalu learned from a teacher in the orphanage, the teacher likes to plant some flowers and plants, as a result, several children were kind, their own urine directly on the flowers and plants, said to help the teacher fertilize, the result was directly burned to death of those flowers and plants, making the teacher cry and laugh, and it was from the teacher who loved flowers and plants that Guo Dalu knew that the original manure had to be cooked before it could be used as fertilizer.

Later, Guo Dalu read some miscellaneous books, only to find that Chinese farmers have a long history of using human and animal manure as fertilizer, but until the Song Dynasty, they directly used fresh fertilizer, and after the Yuan Dynasty, they knew how to accumulate fertilizer. In this way, I have not yet had the experience of applying human fertilizer correctly in this ancient world.

Guo Dalu beckoned to the villager: "Uncle, I still want more human fat, the more the better, can you help me collect it?"

The villager grinned: "Brother Guo, your family only has a few acres of land, and these two picks of people are enough to fat." ”

Brother Hao has been guarding Guo Dalu's side, and then interjected: "Uncle, what Brother Guo wants you to do must be reasonable, don't ask why, go and pick fat, the more the better." I'll send our family's human fat first. ”

Carpenter Zhou was shoveling grass for his family's field, when he saw Guo Dalu hurrying over: "Uncle Zhou, can you help me find a few big water tanks, the bigger the better." ”

Carpenter Zhou straightened his waist: "Guo Dalu, what are you going to toss? Won't you want to do some drip irrigation in the back mountain? That can't be done, the hillside fields are not as watering the ground as the water by the stream, and the water alone can toss you to death." ”

Guo Dalu said: "It's not drip irrigation, I want to use this water tank to cook manure." ”

The hoe in Carpenter Zhou's hand fell to the ground, and he looked at Guo Dalu with the eyes of a madman: "You, what are you talking about?!Cooking manure? Is that the manure that fertilizes the crops?"

Guo Dalu nodded very seriously: "That's right, if Uncle can find some grass ash, bean dregs, bone meal, human hair, and cook them with manure, it is a good fertilizer." ”

Carpenter Zhou stayed for a long time, and suddenly remembered the advice of the old village chief Zhu, and asked him to cooperate with Guo Dalu as much as possible, and he slapped his thigh heavily: "Okay, I'll find you a big tank!"

Carpenter Zhou was not ambiguous, and took a few villagers to bring up a large water tank of four mouths and seven stones from the village below the mountain, which was the water tank that people were using, and Carpenter Zhou directly emptied the water and carried it up the mountain.

Guo Dalu commanded Zhou Carpenter and Hao Ge'er and others, according to the mountain, the four cylinders were placed side by side, and then a row of shallow pits were dug out below, and the villagers were called to pour the dung, grass ash, and human hair that were picked up the mountain.

A fire was lit under the water tank, and as the temperature became higher and higher, the feces in the water tank were bubbling and bubbling, and Guo Dalu had already stood far away - smelly, it really stinked to death, just looking at it disgusted to death.

What Guo Dalu is doing is boiling manure, which is also a kind of farmhouse fertilizer that is circulated among the people. The generally used cellar manure method needs to be cooked for several months or even half a year before it can be used, and now Guo Dalu is short of time, so he can only use the cooking manure method.

It's just that this job is really not capable of human beings, looking at Brother Hao holding a long wooden stick, stirring the boiling feces vigorously, Guo Dalu is about to vomit. Sure enough, he couldn't really get along with the working people, he was afraid of being dirty, tired, and bitter, and his petty-bourgeois style was serious.

But the villagers were huddled around the dung tank, talking about it: "What's going on here? Oh, how can a good water tank be used to put manure, and it's still boiled." ”

"What do you know, this is called boiling manure, Brother Guo just said, we used to apply fertilizer in the wrong way, this fertilizer is easy to hurt the crops. ”

"Hey, fresh, I've never heard of boiled manure being cooked. ”

"You haven't heard of drip irrigation before, but if you look at the kudzu grass field, if Guo Ge'er didn't come up with this method, we are still tossing in the kudzu grass field. ”

"If you want me to say, let's try according to Brother Guo'er's words first, anyway, no matter how neat it is, it will be abolished these four water tanks, but if it really happens, it will be good for anyone to get a few more mouthfuls of grain in the field. ”

As soon as the villagers heard that there was more food, they all nodded, yes, in the famine year, in order to have an extra bite to eat, they could sell their sons and daughters, but now they are just boiling dung, what is the big deal.

Guo Dalu listened to the discussion of the villagers on the side, shook his head and sighed in his heart, these villagers are really poor and afraid, it is good to be able to get a little more grain, but in the miscellaneous books he saw before, it was said that the fields fertilized by boiling manure can harvest more than the fields with raw fertilizer.
