ps: Those who are familiar with Lao Yang know that Lao Yang actually likes PS very much, but now there are very few, and he doesn't dare to open a single chapter, just because the editor is afraid of criticism。。。。。。

Xiao Peng was surprised by the efficiency of the Institute of Zoology, and after lunch, the two sides negotiated the cooperation agreement and the treatment of Academician Liu and others, and signed the contract.

"Academician Liu, why do you believe so much that I can do a good job in beef cattle improvement?" Xiao Peng asked Academician Liu puzzled, this Academician Liu agreed too quickly, right?

Academician Liu shook his head: "To be honest, I really don't have much hope. ”

"Ahh

Academician Liu showed a sly smile: "Who made Qianliyan's seafood so delicious? You say I'm so old, I really don't have time to eat if I don't eat something delicious. I've decided, I'll go to your place to eat and drink, and I'll talk about it when I'm happy. ”

Xiao Peng was stunned for a long time, and raised his thumb: "Old Liu, you are awesome!"

Academician Liu laughed and said: "How can I say that I am also a scientific researcher of Qianliyan now, right? You can't just take money and not work, can't you? I'll introduce you to a kind of cattle, maybe it can make you get twice the result with half the effort." ”

"Oh?" Xiao Peng heard and asked, "Is it a native Chinese cow?"

"Of course it is, Boss Xiao, don't think that the local cattle in China are the 'five famous cattle', we have more cattle in China. There are more than 20 varieties of cattle breeds, such as Jiaxian Red Cattle, Dabie Mountain Cattle, Zaobei Cattle, Bashan Cattle, Wuling Cattle, Leiqiong Cattle, Panjiang Cattle, Gaofeng Cattle, Tibetan Cattle, Guangfeng Cattle, Zhoushan Cattle, Kazakh Cattle, Mongolian Cattle, Fuzhou Cattle, etc., as well as several yak cattle breeds!

Xiao Peng was taken aback: "So much, in my eyes, there is only beef。。。。。。 I don't know what kind of cattle Academician Liu recommends I use?"

"There are three big black-haired scalpers in the world. The Danma Cow is one of them, in fact, we also have one in China, that is, the Bohai Black Cow. It is the local cattle of your Qilu Province. Academician Liu said.

"Ah, we still have such a kind of cow in Qilu? I haven't even heard of it. "Xiao Peng has never heard of this kind of cow at all.

Academician Liu introduced: "The main production area of Bohai black cattle is Wudi County in Qilu. You haven't heard of this kind of cattle because the Bohai black cattle were almost extinct at that time. In the last century, all kinds of blind cattle improvement plans, to the Bohai black cattle breed brought a great impact, the central production area of the stock of a sharp decline, the distribution range is also shrinking, especially since the beginning of the 21st century, with the continuous improvement of the level of agricultural mechanization, the advantages of Bohai black cattle in agricultural production are becoming more and more diluted, coupled with the increase in breeding costs, so farmers no longer breed Bohai black cattle at all. The ridiculous result is that after the end of various cattle improvement programs, people found that it was better to still have Bohai black cattle, so they had to develop slowly little by little, and it took nearly ten years for Bohai black cattle to develop to about 10,000 people. ”

"That's it!" Xiao Peng clapped.

Academician Liu said: "Boss Xiao, don't worry, in fact, Bohai Black Cattle also has a problem, that is, its net meat rate is low, which is nearly ten percentage points lower than that of Luxi cattle and other cattle." ”

Xiao Peng smiled: "It's okay, I'm thinking about their number now, there are more than 10,000 in total, how many can I get? ”

Besides, Boss Xiao, raising cattle is not raising chickens, so you don't have to worry about throwing them there, and you have to do a lot of preparation for raising cattle. Academician Liu said.

"Huh, what else do you need to prepare?" Xiao Peng was puzzled.

Academician Liu smiled: "I only feel like I'm on a thief ship now." Boss Xiao, it turns out that you don't understand anything, and you want to play it out. ”

Xiao Peng shrugged: "So rely on you experts to help, otherwise why would I let you go to Qianliyan?"

Academician Liu said: "If you want to raise cattle, you must have a cowshed. If you want to raise more than 1,000 cows, it is best to have a cowshed that is 60 meters long and 10 meters wide, with double-sided troughs and good ventilation. Such a barn can raise about 100 cows, and you will also need to build a hay shed to store the hay. You also need to prepare a manure tank, otherwise so much cow dung will fill your Qianli rock for you. ”

When Xiao Peng heard this, he almost fainted, and when he thought of the picture of Qianliyan being heaped with cow dung, Xiao Peng shuddered: "Academician Liu, is there any way to solve this problem?"

"It's not impossible, like building a digester, but a few digesters can fill it for you. Academician Liu said. "So you really want to do it, you have to deal with it in several ways at the same time to solve this cow dung problem: first, build a few biogas digesters, which can solve part of it, and the other part, use compost fermentation to carry out non-toxic treatment and make organic fertilizer, because the composting process can form high temperatures, can kill all kinds of germs and insect eggs, and a variety of components in the manure can be converted into effective nutrients for plant growth, which can be directly applied to crop planting. The advantages of composting are low cost, large processing capacity, and no secondary pollution, but there are also disadvantages, that is。。。。。。 It doesn't smell good。。。。。。 ”

Xiao Peng thought of a strong smell of cow dung on Qianli Rock, and felt that the whole person was not very good. "Academician Liu, is there any other way?"

Academician Liu frowned: "Boss Xiao, after all, I am a biological expert, not an agricultural expert, and I really don't know the specific details." ”

Chen Zetao, who was on the side, spoke: "I still know two ways. ”

"Tell me about it. Xiao Peng hurriedly asked.

Di Wei said: "One way is to breed earthworms from cow dung, which is done by general cattle farms, you know, earthworm powder is a good feed additive, higher than the protein content of fishmeal, and the fertilizer made of earthworm manure is a good fertilizer with a high price! Another way is to build a greenhouse to grow Bisporus mushrooms with cow dung, the main reason why Bisporus mushrooms are expensive is because of the small planting area, and the main raw materials for planting Bisporus mushrooms are dried cow dung and straw. ”

Xiao Peng scratched his head, this Nima is not suitable, relatively speaking, the establishment of a biogas digester is the least polluting. Xiao Peng didn't want to be the smell of cow dung before he reached Qianliyan.

As if seeing Xiao Peng's embarrassment, Chen Zetao said: "Then you just use the simplest way." ”

"What's the way?" Xiao Peng hurriedly asked when he heard that there was another way.

"Sell cow dung!" Chen Zetao explained.

"Can cow dung still be sold?" Xiao Peng was dumbfounded.

Chen Zetao said with a smile: "Of course you can sell it, don't underestimate cow dung, this is a good thing that sells as much as there is, and now with the development of the edible fungus industry, the demand for cow dung is also increasing." You must know that cow dung is an excellent raw material for edible fungi, so cow dung is indispensable for the production of high-quality edible fungus products. So there's a lot of cow dung to buy. Basically, demand is in short supply. ”

Xiao Peng looked at Chen Zetao: "How do you know so well?"

Chen Zetao said: "My hometown is engaged in edible mushroom farming, of course I understand. Boss Xiao, if you really want to sell cow dung, I will contact you to ensure that you sell as much as you want. ”

"Damn, then you didn't say it earlier!" Xiao Peng said angrily: "I don't have to sell it to them, as long as I can guarantee to take it away, I will give it away for free!"

Chen Zetao said: "Boss Xiao, isn't your island a forest, don't you leave some cow dung to make organic fertilizer?"

"I want a fart organic fertilizer. There are so many on the island, except that the animals are birds. So much guano is not enough to make organic fertilizer?" Xiao Peng said: "No, I'll call, and the contact person will go to build the cowshed." ”

"So anxious?" Academician Liu asked.

"Of course, if you want to do it, you can do it, I'm a person who wants to play it out and forget about it when I turn around. Xiao Peng said with the phone.

"Can such a big investment be forgotten and forgotten?" Chen Zetao didn't believe Xiao Peng's words.

"Big, I took out a few fish, sold them, and came back. Xiao Peng said this definitely to pretend to be forced.

Academician Liu instructed: "Don't forget to install a manure scraper when building a cowshed, cleaning up the manure is fast and trouble-free." By the way, buy some alfalfa seeds to plant on the island. ”

Xiao Peng waved his hand, signaling that he knew about it, and called Yang Meng and asked him to find someone to build a cowshed, which was on the other side of Qianli Lake, far away from the place where people lived, and close to the water source.

After everything was arranged, Xiao Peng hung up the phone and said with a smile: "It's done." When are we going back to Qianliyan? Academician Liu. ”

Academician Liu said: "Preparations are being made now, do you think the transportation of the white-sided dolphin is so simple? The preparation work alone will take at least a few days! It will only require the cooperation of the relevant personnel on Qindao." ”

Xiao Peng was stunned: "So troublesome? Isn't it okay to load a plane and fly over? As for making preparations for so long?"

Academician Liu was drinking tea, and after listening to Xiao Peng's words, he sprayed out, fortunately Xiao Peng hid quickly, otherwise he would have to spray his face: "What you said is simple, you go and steal a plane for me?"

Xiao Peng looked at Lu Ya, and Lu Ya quickly shook his hand: "I don't think it's possible for my grandfather to help with this." You know my grandfather's man, the open-mouthed principle, the closed-mouth principle. ”

"Yes, it is better to ask for someone than for yourself. Xiao Peng sighed, and picked up the phone again after speaking: "Hey, I need to rent a plane to fly from the imperial capital to Qindao." Oh, there's cargo to transport, two white-sided dolphins, yes, live, we have a special entourage, yes, yes. The sooner the better. ”

Buttoning up the phone, Xiao Peng shook his mobile phone at Academician Liu and Chen Zetao: "That's it! Academician Liu, I suggest that you and your students prepare their luggage." ”

Chen Zetao was stunned for a long time and then said indignantly: "I really can't hold it back!
