Because the most difficult step in the whole process is to extract the mycelium, now that the bacterial strain has successfully developed, it shows that there is no problem with her extraction method.

Then the next step is to find suitable materials to make bacterial bags, and use a small amount of bacterial strains in the bottles for further breeding to cultivate a large number of bacterial strains to reach the quantity conditions that can be planted.

Common materials for mushroom bags in later generations include sawdust. In this era, there were no grinders, and even if there were, it would be impossible to obtain them. So as far as the current situation is concerned, it is difficult to collect large quantities of sawdust. We have to find ways to find suitable alternatives to sawdust.

Just fine.

Pretending to be worried, Si Ningning filled the military kettle with water and made room.

I went to the team to collect rice bran and then went to the pig pen. Unfortunately, Hegu and Sanmiao were not there. Si Ningning had finished his work and they hadn't come yet.

Si Ningning sat on a stone pier in the shade under the wall and waited for a while, but no one came. Si Ningning guessed that something happened to the Chen family, so she didn't wait, got up and went to the threshing floor.

Originally, he thought of picking up a small bundle of straw, but when he thought that the educated youth didn't seem to have a serious chicken coop, Si Ningning simply hugged half of the bundle.

Returning to Zhiqingdian, he threw the straw in the shade at the door. Si Ningning opened the door and carried the rabbit cage in the main room to the door step for ventilation and smell. Then he took the small horse and sat on the edge of the straw, starting to plate the chicken coop.

.

Si Ningning was busy with her hands and was still thinking about the issues before going out.

Mushrooms are not only cultivated on mushroom bags. As long as the temperature and humidity are appropriate, land and rotten wood can be used as seed piles for cultivation.

But if there is a bacteria pack, you can use the strains initially cultivated in the small bottle to expand to a whole pack of strains. In this way, you can basically cultivate a strain by breaking off any piece of such a large pack.

A bunch of mushrooms come.

It cannot be said that one bacterial bag can be divided into countless portions, but there should be more than ten or twenty portions, right?

It is equivalent to developing one seed into twenty seeds. This is just one bacterial package. If there are two or ten bacterial packages, the efficiency will be even more impressive.

But what can achieve the same effect as sawdust?

Si Ningning was thinking, and suddenly her thumb hurt.

When I lowered my head and looked down, I found that a piece of straw had just gotten stuck in the hole scratched by the bamboo yesterday.

Si Ningning pulled out the grass clippings, put his index finger against the wound on his thumb and rubbed it gently, then dragged the grass clippings with his other hand and blew in a breath.

Small grass clippings are floating in the air, and under the sunlight, they appear light blue for a while, and a little yellow for a while.

Si Ningning's eyes followed the piece of grass until it fell to the ground. There was a "ding" in her mind, like the moment when fireworks exploded, and she suddenly had an idea.

"straw!!!"

"What happened to the straw?"

There was a sudden sound in her ears, and Si Ningning was startled. She turned her head and saw He Gu and Sanae squatting beside her.

The two little ones should have come here when she was in a daze just now.

Si Ningning pretended to be serious and put her hand on He Gu and San Miao's foreheads. "Why didn't you say anything when you came? You scared me."

An apology flashed across Sanae's face, but Hegu held his belly and jumped away happily.

Si Ningning looked at Waiting Hegu angrily, then waved her hand to ask him to stand in a shady place:

"I'll set up two chicken coops and they'll be ready soon. Why did you two come here so late today? What happened at home?"

"No, elder brother asked us to wash our hair at home and then come back." Hegu thought for a moment and said seriously.

Si Ningning looked sideways and realized that Hegu's hair was indeed quite fluffy, while Sanae's hair was longer, and the corners were still a little wet at the moment.

Si Ningning didn't pay attention just now, thinking it was because it was too hot and she was sweating.

"Your elder brother is quite particular." Si Ningning chuckled twice.

Seeing her smile, Sanae laughed too, "Sister, my eldest brother asked you to help me cut it too."

Si Ningning asked with a smile: "Okay, what kind of cut do you want Sanae to have?"

"Hmm... cut it like the second brother." Sanae pointed to the grain, "The elder brother said, if you cut your hair short, it will be less likely to get lice."

"Why do little girls cut their hair so short?" Si Ningning gathered the chicken coop and led the two little ones into the house. "Lice has nothing to do with the length of your hair. Just wash it frequently. I'll cut it for you later."

Sanae's eyes wandered as she thought for a moment, then nodded obediently.

Si Ningning put the chicken coop on the chicken coop at the door and shouted to He Gu to take the pony. She then went into the house to get a washbasin, a towel, a comb, and small scissors. When she came out, she waved her hands and led the two birds toward the well.

go.

"Come one by one, cut Hegu first." Si Ningning filled a half basin of water and asked Hegu to sit on the horse. She put a towel on Hegu's shoulders to prevent the broken hair from falling into the clothes when she was cutting.

Turning around made my body itch.

Si Ningning had used a clipper to push her grandfather's hair and cut it seriously, but this was the first time.

Although there was no clue, Si Ningning felt inexplicably confident when she thought of Song Shuhan and Li Lingyuan's haircuts.

How to say something?

In everything, I am afraid of comparison!

Si Ningning's lips curled up into a soft smile. He Gu turned his head and raised his neck to look at her, "Why are you laughing?"

"You're not laughing at anything. Hurry up and sit down."

"oh!"

"Is it okay to cut it shorter?"

"Well... Big brother said that if you can shave your head bald, you can shave your head bald."

Si Ningning wetted the comb in the basin and combed Hegu's hair smoothly, "Shave your head? I'm not that capable, but your elder brother is. You can go home later and ask your elder brother to shave it for you."

Shaving your head requires specific haircut tools, but Si Ningning doesn't have any. The most she has on hand can cut Hegu's hair a little shorter.

"I don't want a bald head!" He Gu protested and shook his head, "A bald head looks too weird."

He said, "It's like an egg."

Si Ningning laughed out loud, "Okay, don't move around, I'm going to start cutting."

"Oh!" Hegu sat up, obediently and no longer moving, but his small mouth kept chattering, "By the way, Si Ningning."

"What?"

"When we came here, Sanae and I met Uncle Hongbing. Uncle Hongbing asked us to take a message and asked you to go to your house when you go to work in the afternoon. If you have something to say to you."

"good."

Si Ningning said "hmm" and guessed that it was about the literacy class.

He Gu's hair was combed and smoothed, and Si Ningning put a comb under the hair and slowly cut it.

The neck tends to sweat in summer, and children are more likely to get prickly heat. Therefore, close to the neck, Si Ningning's comb is basically close to the scalp on the back of Hegu's neck, and is cut as short as possible. On the contrary, if it is close to the top of the head, the length will be slightly

Be a little looser.

After pruning for more than ten minutes, Si Ningning reached out and fiddled with Hegu's hair, shaking off the broken hair, and then walked around to Hegu to look at it.

Hmm...how should I put it?

The broken hair is long at the top and short at the bottom. While it is clean and tidy, the side of He Gu's face is also exposed.

Originally, his small face was as big as his palm, and his chin was pointed and frightening. He always looked a bit sickly. But now, He Gu's whole face is revealed. His small face plate has become a little bigger. The previous sickliness is gone. Instead,

Revealing a little shot's exclusive breast cuteness.

Si Ningning pinched Hegu's cheek with satisfaction, "Very good!"

After gently patting Hegu's neck to clean up the broken hair stuck to it, Si Ningning took out a towel, shook it out, and asked Sanae to sit on the pony.

Wetting the comb as well, Si Ningning combed Sanao's hair through and said, "I'll boil a pot of water while I'm cooking. I'll wash your hair after dinner."

"But it was already washed when we came here, so it's not dirty."

He Gu squatted next to the basin, scratching his neck and taking a look in the water. After a while, he raised his head in displeasure and looked up.

The shadows of the trees above the head were far away, so the illumination was clearer. He Gu raised his head to look, and there was only a shadow outline in the basin, and nothing else could be seen.

Si Ningning was thinking about how to cut Sanae, and replied smoothly: "The purpose of washing your hair is to wash away the excess hair, so as not to leave it everywhere, prickly and itchy. It does not mean that you are dirty."

"oh!"

"Does Sanae know how to tie her hair?" Si Ningning asked.

"Yes." Sanae responded, and then added after a while, "But if it's not tied well, it will always fall apart easily."

Si Ningning nodded, knowing better.

Sanae couldn't tie her hair well, and there was no woman in the Chen family. It was basically impossible to expect Huo Lang to tie Sanae's hair.

Even if Huo Lang knew how to do it, he wouldn't be able to take care of it every day.

So... it is indeed more appropriate to cut it shorter and easier to manage.

Sanae's own hair was as long as her shoulders. Si Ningning lifted a strand of her hair, lowered her head and said before using the scissors: "Do you want to cut it shorter?"

I originally thought that the little girl would be reluctant to cut her hair short, but Sanae was ignorant and didn't look strange. Instead, she nodded obediently.

Si Ningning was no longer so worried.

Use the scissors to find the position of the earlobes on both sides, and "twist" it a few times. Sanae's hairstyle gradually takes on a student-like bob.
