In the following days, Aunt Qin and Mother Qin were busy with Qin Chuan's marriage every day, and Qin Yu also knew what was going on, and he didn't urge Aunt Qin to do anything.

Aunt Qin didn't let Qin Yu wait longer, she took advantage of Li Dian to come to their house, and told Li Dian about Qin Yu's plan.

Ridian: "That's what you've carved on the wooden slabs these days?" ”

Qin Yu: "Teacher, you know?" ”

Li Dian smiled: "You have broken several Mudu, how can you not see it as a teacher?" ”

Originally, how to design this rough biogas pit to make it more practical, Qin Yu as soon as he had time to draw on the wooden slab, if the painting did not suit his wishes, or the drawing was wrong, he had to use a knife to cut off the surface of the wooden defilement, and re-painted, this is the eraser of the pre-Qin period.

After many times, the wooden slip becomes thinner, and it can no longer be used, so it has to be replaced with a new one.

Li Dian often went in and out of Qin's house to teach Qin Yu to play the flute and touch the qin, and he had a lot of contact with him, and he knew more about him than Qin's mother.

Qin Yu said embarrassedly: "In the past few days, the disciple finally felt that he could give it a try, so he told the eldest mother, asked the eldest mother to say something for me, and asked the teacher to complete it." ”

After that, he bent down and gave Li Dian a disciple salute.

Li Dian held his elbow, kept brushing his beard with one hand, looked at the wooden stump on the desk, and said: "It is said that you should go to tell Tian Zuo and the township Sikong first, but you are just tossing in your own homestead, and it is not much of a fortification. Fish, if you just give it a try and don't attract people's attention, the teacher will allow you. ”

Yao County Decree left office, and some officials were transferred, and the new Liyang County Decree has not yet been determined. At this critical time, no one wants to make a bird with a head, and they all want to □□. Especially in their wealthy Xixiang, Ridian was almost certain that if he reported the matter of Qin Yu's side, there was a chance that no one would take the risk of agreeing.

After all, it is a matter of farming, and if you do it well, you may not be rewarded for your merits, but if you do it wrong, it is a living target.

Liyang Xixiang, it's really getting richer and richer, and when he goes out with this little Artemisia Lidian, there are a lot of Sifu subordinates to give face.

Aunt Qin and Qin Yu both understood, and what they said in the dictionary was very clear.

First, it must be in its own homestead, not beyond the scope of its own home, not on the road, in the field, not good.

Second, the scale should be small, give it a try, and not build large fortifications, otherwise, once it attracts attention, it will be difficult for him to explain to the above.

The third is to take care of the neighbors, and not let the neighbors report their homes. If a neighbor goes to report the construction of their house for fear of being consecuted, the matter can escalate into a civil case.

Qin Yu went to see Qin's mother.

Aunt Qin nodded, and promised Lidian: "The old woman still has some face among the neighbors, and she will definitely say hello first." The old woman here will also take a good look at him and don't let him toss around. ”

Ridian smiled and nodded.

Qin Yu got up happily and saluted the two: "Yu has thanked the teacher and the eldest mother." ”

......

In fact, the wheat that Qin Yu cultivated seamlessly in his own field was seen by the neighbors, and they all silently observed his one-third of an acre.

Qin's mother took Qin Yu to the surrounding neighbors' homes for a while, and they all said that they would support Qin Yu to try, and some of them also booked the so-called "fertilizer" with Qin Yu, hoping that their own fields could be fed according to his method, and after feeding, they hoped to produce more food.

Over the years, they have also discovered that this little prince Qin, there is nothing he can't do if he wants to do. Anyway, it's not digging a hole in their own house, what are they doing with so many hearts? Besides, the Qin family is generous and never hides their selfishness, if they really let this little boy do it, their neighbors will be the first to benefit.

Therefore, Aunt Qin took Qin Yu to say that there was nothing in the neighborhood that disagreed.

With the support of the two talkers, Qin Yu can use the servants at home to find a suitable day to break ground and excavate.

The reason why he told Qin Damu and Li Dian that he was digging a manure pit, instead of digging a biogas pit directly, was because he was embarrassed to say that he was digging a biogas pit.

As the name suggests, biogas pits are used to produce biogas. The biogas produced can't just be left in the pit, right? You have to put a gas duct in the pit, build a gas pipe, what piezometer barometer or something like that, at the very least, the biogas is produced, you can't just put it in the air and let it dissipate by itself, right? Not to mention the problem of waste and waste, even if there is too much, this biogas is also toxic. Therefore, it is necessary to have a stove that can burn biogas.

In fact, as long as we take action, these problems can be solved. However, if it is really done, just firing pottery pipes is a big project, and it is definitely not something that can be decided by Lidian alone.

Therefore, at the very beginning, Qin Yu wanted to make this "biogas pit" as simple as possible, removing the gas conduction, and leaving only the manure fermentation link, which was much easier to operate.

He is now making a good start, and after more people see its benefits, Qinyu can smoothly advance to the next step, and finally be able to use biogas for cooking and lighting, so as to realize the green ecological cycle of manure - biogas, biogas residue, biogas slurry - return to the field, fruit garden, and fish pond.

In addition to the fields and orchards, Qin Yu also plans to dig fish ponds in the wetland to raise fish, turtles and shrimps, lotus roots, water chestnuts and other aquatic products, but these are all future plans, at present, he has to devote himself to the construction of this simple biogas tank that does not use biogas - manure tank.

First of all, it is to dig a pit, dig an original pit with a diameter of one step and a depth of one step.

I saw Bo Niu standing still in the position designated by Qin Yu, Su Lian made a mark on his heel, and then Bo Niu began to raise his foot and walk forward, taking a step with his left foot, taking another step with his right foot, and then standing still, Su Lian drew a mark on his toe, so that the distance of one step came out.

That's right, Qin Guo's step is to take one step with both feet, the length is about one meter five, Bo Niu is tall, and he takes one more step than ordinary people, about one meter eight. Qin Yu specially invited him to take a step, just to dig the pit as big as possible, because after the pit is dug, he also has to pad stones at the bottom of the pit and ram the soil on the pit wall, so that the pit does not seep water to the outside, pollute the soil, and cannot let the rainwater and groundwater outside penetrate in, so that the pit dug in this way will soon be filled with silted soil.

After drawing the mark, Bo Niu said to Qin Yu: "Little master, I'm going back, are you here alone to watch?" ”

Bo Niu is the main force preparing for the wedding for Chuan, and he is inseparable from him everywhere in the family, and he can't take care of him by Qin Yu's side all the time, so he is a little worried about handing over Qin Yu to the servants below to take care of.

Qin Yu said with a smile: "Uncle Niu, it's only a few steps from home here, if I shout, you can all hear it, you can rest assured, I can do it alone." ”

Bo Niu looked at the yard not far away, it was indeed not far, so he had to pretend to be relieved and said: "The sun is spicy when he sees it, the little master should arrange to go home early, don't let the old master and the master mother worry." ”

It's just digging a pit, just watch the people below dig it, don't get involved with you, a villain.

Qin Yu said: "I know, when the sun rises a little more, I will go home, and I won't let the eldest mother and mother worry." ”

Don't you know that watching people dig holes is also addictive? I used to watch people digging pits on my mobile phone for most of the day, not to mention digging on the spot?

Bo Niu finally turned around and left.

Qin Yu asked people to straighten the rope between the two marks, draw a straight line along the rope, and then he went up and stepped on a point about the middle, so that one person was immobilized, and the other person pinched the rope to meet that person.

The rope is folded in half, Qin Yu finds the middle point, steps on it, and then asks the person who pulls the rope to hold a stone in the palm of his hand, pulls the rope to the ground and turns in a circle, while turning, the stone in the palm of his hand draws an arc on the ground at the same time, and after the end and end are connected, a circle with a diameter of about one meter eight will come out.

Su Lian stepped forward with a bamboo spear, deepened the traces of the circle, and then said to the five servants with the iron jue, "Start digging." ”

Anyway, let's start digging first.

Qin Yu stood aside and watched.

There are many people and great strength, besides, this pit is really not big, and it is less than half an hour small, and the pit that Qin Yu wants will be dug well.

Then, Su Lian instructed the others to carry water, sand, grass and wood ash, and quicklime, and mix them with the excavated soil in a certain proportion to ram the pit wall.

Qin Yu stood aside and watched them busy with their work, and asked Su Lian, "Su Lian, is the house we live in made of such mud?" ”

Su Lian smiled: "How can there be so much lime and grass ash to build houses for people?" Generally, the houses where the Qianshou live are made of yellow mud, at most exposed to the sun for a few days, the grass seeds and insects inside are sunburned to death, and then mixed with grass clippings to ram the walls, so that the house can be built stronger. I used the method of building a city wall, which is stronger, that is, the pit of the little master, your pit is small, otherwise, I would not dare to use it like this. ”

STM pit is small, I feel that you are secretly poking at me, but I have no evidence.

Qin Yu: "Is it okay to just add water and live like this?" ”

Su Lian: "You have to wait for an hour or two, the sun will come up, spread out the sand first, and then come and add quicklime and mud later." ”

Qin Yu looked at the big sun above his head, and said to the servants who were already beading with sweat on their foreheads, "Okay, that's all for the morning's work, let's go home." ”

These servants are all teenagers, they belong to the kind of people who have no hair on their lips and are not firm in their work, and they are dispensable for the important matter of marrying a wife in the family, so Aunt Qin sent them to Qin Yu to listen to the call.

At this time, they heard Qin Yu say that they were out of work, they all cheered, carried the iron hammer, and hugged Qin Yu and walked in the direction of home.

A young man said to Qin Yu: "Little master, is it okay for the slave to carry you away?" It's a little faster this way. ”

Ti, you think the master is walking slowly!

Qin Yu swooped forward and shouted, "I don't want you, I'm faster than you!" ”

As soon as Qin Yu ran, these young men also ran with him, joking with Qin Yu and playing with each other and going home.

Su Lian didn't follow, he carried the iron hammer and walked slowly behind, looking at the children and big children running wildly in front of him, shaking his head, showing a relaxed smile.
