Rebirth on the top of the mountain, my herding career

After dinner.

Qin Xifeng left Gulidan's house and returned to his yurt on horseback. The first thing he did after entering the house was to receive the event props without hesitation.

A piece of note paper suddenly appeared on the coffee table. He picked it up and looked at it. Sure enough, it was the contact information of the researchers. It included mailing addresses, phone numbers, everything.

The words "response to all requests" are also specially marked on it. Obviously, as an event prop, the necessary preparations have been made in advance.

"Just by establishing contact with these researchers, I have already made money!"

Qin Xifeng was very happy. These researchers covered the fields of animal husbandry, veterinary medicine, feed, etc. If he had any questions in the future, he would definitely get satisfactory answers from them.

However, the top priority is to trial-produce silage as soon as possible. The first person to deal with will definitely be researcher Yu Beichen from the Feed Research Institute.

Qin Xifeng memorized the contact information of the three researchers and put the note away.

He sat in front of the coffee table and was still thinking about the next step. Compared with hay feed, silage had obvious advantages, but the disadvantages were also obvious.

Silage is tender and juicy, with high nutritional value and good palatability, but the production threshold is high and requires special facilities, fermentation lactic acid bacteria, etc.

And the risk of production failure is not small, especially in plateau areas.

In plateau areas, the temperature is low, the oxygen content is low, the atmospheric pressure is low, and the low temperature and pressure environment is not conducive to the fermentation of lactic acid bacteria, which may cause mold and deterioration of materials.

Therefore, the screening of low-temperature lactic acid bacteria is a key part of the trial production of silage.

Qin Xifeng plans to go to the countryside tomorrow and call researcher Yu Beichen to ask if there are currently fermentable lactic acid bacteria suitable for plateau areas.

The next day.

He got up early in the morning and greeted Atik and Gulidan respectively, then led two yaks and a horse and went straight to the countryside.

"Xifeng, why are you here? I'm planning to send you the flour and oil you need in the next two days..."

At noon, Qin Xifeng came to Wang Hai's house.

Wang Hai and his wife are not here, and only Wang Jianjun is preparing to cook noodles.

"I just came here to do some errands. When I go back, I will take it back myself, so you don't have to make a special trip."

Qin Xifeng did not enter the house. He then went to the corral and settled the horses and yaks before returning for lunch.

Lunch was relatively simple. The two of them cooked two bowls of noodles and a plate of cold vegetables to fill their stomachs.

"Jianjun, you can clean up yourself. I'm going to make a long-distance call."

Qin Xifeng ate the noodles in a hurry and went to the post office. There were not many people waiting to call at the post office, so he quickly dialed the number of Yu Beichen's office.

"Hello! I'm looking for Researcher Yu Beichen."

"I am, who are you?"

"Researcher Yu, I am Qin Xifeng from Taal County. I am looking for you to ask about making silage on the Palpaha Plateau..."

Yu Beichen's voice sounded not very old, probably less than 50 years old. When he heard Qin Xifeng announcing his family name, he smiled and said:

"It turns out it's you... I heard Old Tang from the Beijing Institute of Geography talking about you a few days ago. He has a glacier research project with your Provincial Academy of Sciences. He will go to your place in a few days.

.”

The Old Tang Dynasty mentioned by Yu Beichen is the Tang Wannian of the Institute of Geography.

Qin Xifeng has a cooperative relationship with the Beijing Institute of Geography. Before going to Taman Wetland, he had been regularly sending relevant meteorological data to the Institute of Geography, and the recipient was this person.

He had also been collecting meteorological data on his way to nomadic life. When he came to the countryside today, he planned to send the data he had accumulated for several months.

"Researcher Tang is coming? Welcome!"

Qin Xifeng said a few polite words, and then got down to business, talking about his preparations for trial production of silage, and asked Yu Beichen about the screening of low-temperature lactic acid bacteria.

"Xiao Qin, you really asked the right person. I have done research on this topic with my students before. After our screening, we determined that Lactobacillus plantarum, Lactobacillus casei, Pediococcus pentosaceus, and Lactobacillus coryneformis are the most resistant to low temperature.

Excellent lactic acid bacteria..."

Yu Beichen did not hide his secrets and explained his research results to Qin Xifeng in detail.

Finally, it was concluded that Pediococcus pentosaceus has the best low-temperature fermentation properties and is most suitable for silage production in plateau areas.

However, he also said that these are laboratory data, and since it is only a small subject, he has not yet conducted field verification.

But for Qin Xifeng, this is enough.

"Researcher Yu, I would like to take the liberty to ask, can you give me some samples of four types of lactic acid bacteria?"

"No problem, this thing is easy to prepare. I'll ask Old Tang to bring it to you later."

Yu Beichen laughed heartily on the other end of the phone. A sample of lactic acid bacteria was just a trivial matter, and he was happy to be a favor.

After Qin Xifeng expressed his gratitude again and again, he hung up the phone.

Knowing the four screened strains of lactic acid bacteria, he can actually prepare them himself. For example, Pediococcus pentosaceus is widely found in pickled cabbage jars, inside silage feed, etc.

But to isolate strains, you need very professional equipment and tools. He doesn't have any of these things, so naturally it's the easiest thing to have ready-made ones.

Adding lactic acid bacteria for fermentation for the first time is equivalent to the "introduction" of the biogas digester. It will not be so troublesome in the future, and he can solve it by himself.

After making the long-distance call, Qin Xifeng sent the weather information and then returned to Wang Hai's home.

"Xifeng, I have bought the flour and clear oil you need. Can you take it back yourself? I will go to your place in a few days. I plan to purchase a batch of live sheep this time."

When Wang Jianjun saw Qin Xifeng, he took out the prepared flour and clear oil.

He has been in the business of long-distance live sheep trafficking for a long time, and has been as far away as the provincial capital, and his ambition is even greater than that of his father Wang Hai.

"I have a lot of things to do recently, so I won't talk to you anymore. Please help me pack these things, and I will leave right away. If you want to buy live sheep, it's no problem. Let Mengzi take you to visit more villages later."

Qin Xifeng didn't hesitate, and immediately brought the yak, and together with Wang Jianjun, he put the items on the back of the yak and tied them up, before embarking on his way home.

When I got home, it was already past dinner time.

Gulidan was feeding six small border sheep outside the yurt. When he saw Qin Xifeng, he rushed up to him and helped him unload all the items and put them neatly.

"Is the matter settled?"

After packing her things, Gulidan learned that Qin Xifeng hadn't had dinner yet, so she rolled up her sleeves and made a pot of soup noodles.

After it was done, she also ate a small bowl with Qin Xifeng.

"Well, the matter is done! I estimate that there will be no problem with the fermented lactic acid bacteria for making silage feed. The next step is to directly conduct the test."

Qin Xifeng ate three large bowls of noodle soup in one go. Feeling that he was not full, he ate more than half of the butter naan bread and then put down his bowl and chopsticks.
