Chapter 33 Mushroom Shed

The inside of the mushroom shed is a bit dark and the humidity is high, but the temperature is quite cool, around 10 degrees.

Song Yu thought he would see piles of mushroom bags like those on TV, but it wasn't.

Instead, I saw a bed of bacteria covered with a layer of nutrient material about 10 cm thick, and the bed was covered with a plastic film.

"This batch of fungi was sown 10 days ago. It is bed sown and is in the germination period. It will be the fruiting period in about 10 days. But in the last three days, I went out to participate in a training class. The mushroom shed I left it to my parents to watch. I thought it would only be three days, and my parents would check the temperature every day, and proper ventilation would be enough.” Zheng Wei sighed, and then said: “I didn’t expect that in just a few days, we found bacteria contamination. I don’t understand, and when I come back to find out, it’s already too late.”

Zheng Wei said, peeling off a corner of the plastic film.

Song Yu, who was standing next to Zheng Wei, felt a burst of hot air coming from the nutrient material, mixed with the smell of decay.

"Look, the mycelium of the inoculated Pleurotus ostreatus is white, and this kind of miscellaneous fungus is light green. You see, this piece, and that piece, are all contaminated by miscellaneous bacteria." A patch of miscellaneous bacteria and plaques on the open bed of bacteria said.

Song Yu looked in the direction that Zheng Wei pointed, and there were indeed some hyphae that were different in shape and color from the mycelium of Pleurotus ostreatus growing.

"Brother Zheng, didn't you ask the experts who grow oyster mushrooms?" Song Yu asked.

Zheng Wei said emotionally: "I asked in the morning. But I asked on the Internet. The person was a technician in an oyster mushroom breeding group I joined. He said it was infected by various bacteria, and it looked like Trichoderma. , said that it may be caused by incomplete sterilization when preparing the culture material. The key point is, he said that once this kind of bacteria is infected, it is extremely difficult to treat. What should we do! "

"Brother Zheng, don't worry, didn't he say there is any remedy?" Song Yu comforted.

"That's right, just follow the conventional method of dealing with the contamination of bacteria. Fortunately, the area infected by the bacteria is less than half, so he said, dig up the material in the contaminated area, sprinkle lime powder and wipe it with 0.3% carbendazim , and then fill in new materials. But he also said that this method may not be so effective in dealing with Trichoderma, and it is very likely that the disinfection will not be complete. Then my bacteria will be useless. It is a waste of work.” Zheng Wei said Lu said bitterly.

Song Yu saw that there were ways to deal with the contamination of bacteria, but Brother Zheng was afraid that if the cleaning was not clean, the pollution would happen again.

In this case, maybe Xiaoye can help him.

However, it is not enough to help openly.

Song Yu pretended to be thinking on the surface, and he had already started to ask Xiaoye for advice in his mind.

[Xiaoye, can you confirm what kind of bacteria is contaminating this bed of bacteria? ] Song Yu asked.

[Mr. Song, it is indeed Trichoderma, but there are also a small number of Mucor and Neurospora. ] Xiaoye replied.

Song Yu frowned and asked: [Can you get rid of these miscellaneous bacteria? 】

[Yes, Mr. Song. 】 Xiaoye replied confidently.

Sure enough, Xiaoye never disappoints when it comes to this type of microbe.

Song Yu felt relieved, and said: [Then after I dig out the fungus material, you will come to eliminate these kinds of miscellaneous fungi.By the way, even the spores in the air are inactivated, by the way, let's clean up the entire greenhouse. 】

【Okay, Mr. Song. 】

Knowing that Xiaoye can solve the follow-up problems, now is to finish the pre-processing.

Although Xiaoye can be more prepared to effectively kill these kinds of miscellaneous bacteria, and it can be done without lime or sterilized disinfectant, but superficial work is still required, so as not to expose your abnormality.

Thinking of this, Song Yu said apologetically to Zheng Wei, who was still distressed: "Brother Zheng, although I am a graduate student, we are not learning mushroom farming, are we? So, I can't give you the solution, so let's treat it as a technician." Let’s do it.”

"However, I am very careful. Then I will be responsible for digging out the bacteria material of the large contaminated part, and remove the other small contaminated parts with tweezers. With such careful cleaning, the chance of re-contamination should be smaller. "Song Yu then said patiently.

After Zheng Wei heard this, he nodded and said: "I also know that it is difficult for others to find you. Isn't this also a rush to the doctor. It would be great if you could help clean up together. Thank you for being the big brother."

Seeing that Song Yu really had no other way, so he could only do as the technician said, whether it would be successful or not was left to fate.

Maybe I'm really not expected to start a business, so I should go back and work as a security guard.

Seeing that Zheng Wei was discouraged, Song Yu could only encourage him and said, "Brother, I believe in my brother's craftsmanship, which was also cultivated through experiments. Not everyone has the patience and care to pick extremely fine straw in thousands of kilograms of soil. of."

After hearing this, Zheng Wei smiled wryly, and said, "Then let's do this. You are responsible for picking out the bacteria, and I am responsible for the subsequent disinfection and feeding. The lime and sterilizer are ready."

"Well! Let's move. Fortunately, there are not so many infections." Song Yu began to dig out bacteria.

Washing hands, putting on plastic gloves, and finding a sterilized shovel, Song Yu began to dig large pieces of contaminated plaque around the bacteria bed.

And Zheng Wei started to disinfect after Song Yu finished digging, and then filled with new materials.

After Song Yu started to pick up the scattered Trichoderma hyphae with tweezers, Xiaoye had already inactivated the miscellaneous bacteria in the whole room.

This busy one afternoon, seeing half of the mycelia of oyster mushrooms lost, Zheng Wei felt very distressed.

"Okay, big brother. It's already done. I've done everything I need to do. It should be fine." Song Yu persuaded.

Zheng Wei said: "I hope. Let's go, it's time to eat."

After a busy afternoon, Song Yu was also a little tired.

I looked up at the time, it was six o'clock.Fortunately, the eating time at home is after 06:30.

After leaving the mushroom shed, Song Yu was about to get on his bicycle and go home.

Where would Zheng Wei let people go, he immediately carried Song Yu to the front yard.

Zheng Wei's parents are already in their 60s. Although they are in good health, their strength is not as good as before.

Originally, the old couple wanted to help out in the mushroom shed in the backyard, but they were stopped by Zheng Wei.

I feel that my parents are old, and I and Song Yu can do this kind of work, and I don't need so many people.He told the elders to prepare dinner.

Seeing Zheng Wei's resolute attitude, Song Yu, who was held up, would seem unreasonable to refuse, and smiled helplessly: "Brother, let me go. If I don't leave, I will stay with you tonight. Let me Call your parents."

"Well, it's settled. Eat at my house, talk before leaving." Zheng Wei said seriously.

Song Yu could only nod with a wry smile, and took out his mobile phone to call Papa Song.

"Dad, it's me. Well, I won't be going home for dinner. I'll eat at a friend's house in Luoxi Village, so don't wait for me." Song Yu said on the phone.

After hanging up the phone, Zheng Wei invited Song Yu into the room.
