In the middle of the ring, Zheng Qilin closed the small notebook and handed it to Old Man Qin.

"Grandpa Qin, any of these grafting results are sold to those scientific research companies, and it is a lot of income. It's all the technology they want to get by breaking their heads. I don't need to, though. ”

Zheng Qilin said seriously.

"You don't need to, you just need to plant any of my achievements on a large scale, too much to say, it's more than enough to earn tens of millions. You really don't want to?"

Old man Qin was suspicious.

Zhang Huan also looked at Zheng Qilin with wide eyes, wanting to remind him to choose one quickly. You know, a while ago, there were several scientific research companies that wanted to spend 5 million to buy one of the grafting results.

"I really don't need to. I just want to learn a little bit from you, if you want, graft on the spot once, and let me take a serious look at it. ”

Zheng Qilin said.

"Hehe, it's better to teach people to fish than to teach them to fish, the young man is good and has a vision. However, I have to remind you that the most important thing in grafting is not grafting technology, but variety breeding. The quality of grafting technology will only affect the survival rate of grafting, but the results of grafting need to be carefully cultivated for several times before they can be obtained. I'll take you over to graft a few first, grafting techniques or something, you can learn as much as you can. ”

Old Man Qin nodded with satisfaction and said.

"Okay, then thank you, Grandpa Qin. ”

Zheng Qilin smiled slightly.

"Come with me over there. ”

Old man Qin said.

Zheng Qilin and Zhang Huan followed Old Man Qin to the small courtyard that was fenced off separately, and the yard was full of fruit trees, including pear trees, peach trees, apricot trees, and so on......

There is a table in the open space, on which are placed some equipment commonly used for grafting fruit trees, including scissors, plastic wrap, blades, bamboo sticks, and grafting clips.

"Because it's summer, if you do grafting, the survival rate will be a little higher with the T-budding method, so I'm just grafting a slip of paper now. ”

Old Man Qin cut a branch from a nearby peach tree, and then cut a branch from the apple tree as well.

The scissors he used were special scissors, and the cut branches happened to be in a "T" shape.

"Lad, don't think I'm just cutting it out casually, in order to do a T-bud graft, you have to cut 1.3 cm below the branch and 1.8 cm above the bud. The depth of the cut should cover the soft green layer underneath the bark, but not deeper. In order to be successfully grafted, the green layer must be exposed to your scion. If you must store your scion, wrap it in a damp paper towel, put it in a plastic bag, and store it in the refrigerator. ”

Old man Qin explained carefully. He soaked the cut branch in a small water bottle on the table.

"Oh. ”

"Hmm. ”

Zhang Huan and Zheng Qilin nodded, looking and listening seriously.

"Don't think it's easy, the proportion and way of grafting will affect the quality and taste of the grafted branches. Choose a place on a branch or sapling, which should be between 0.6-2.5 cm in diameter. This place must be free of any buds, and it would be ideal if it could be kept away from any other buds. Make a vertical slice on the bark, deep enough to expose about 2.5 cm of green! Place the knife at the junction of the slice and turn it to move it up and down so that the green layer is visible. Use scion. Slide the scion containing the buds underneath the cut you just made on the rootstock, being careful not to bring any dust and bacteria with you. If part of the tarp of the scion sticks out above the T-cut, cut it off so that the parts fit together properly......"

Old man Qin talked earnestly while operating, and seemed to be the same as an ordinary farmer grafting fruit trees, but in fact, he inadvertently showed some special know-how.

Zheng Qilin has already remembered it for the first time.

"After tying the scion to the rootstock. Use a resilient rubber material to wrap around the rootstock to keep the buds in place. Be careful not to squeeze or cover the buds. Remove the straps that are tied. In about a month, the rubber you wrap around the rootstock may come loose and fall off. If not, gently unwrap it yourself so that the piece is not too tightly restricted...... Well, it's done. That's it. ”

Old man Qin put down the things in his hand and said calmly.

"Grandpa Qin, I want to ask you something, is this small bottle of ordinary water or nutrient solution?"

Zheng Qilin looked at the small porcelain vase on the table.

"Well, hehe, it's a kind of growth-promoting nutrient solution. ”

Old man Qin said with a smile.

"Can you give me some of your nutrient solution? ”

Zheng Qilin asked tentatively.

"This won't work. This is a special nutrient solution that I have been concocting for many years, and I can't give it to anyone. ”

Old Man Qin refused very seriously.

"Oh yes. It's okay, then I don't want it. ”

Zheng Qilin smiled slightly.

"This is very precious, young man, and it is important to me, so please understand. ”

Old Man Qin felt that his attitude was a bit too much, after all, Zheng Qilin had just healed his ear, which was a great kindness.

"It's really fine, I'll just ask. I can go back and make the nutrient solution myself. It's not too early, so Zhang Huan and I will go back first. ”

Zheng Qilin said.

"You really don't need my grafts?"

Old man Qin asked.

"Well, I've already learned what I want to learn, no need for it. ”

Zheng Qilin said calmly.

"Oh, okay. In that case, I won't force it. ”

Old Man Qin said a little embarrassed.

"Grandpa Qin, then let's go. ”

Zhang Huan also said.

"Okay, go ahead. ”

Old Man Qin nodded.

......

Zheng Qilin and Zhang Huan walked out of Old Man Qin's courtyard gate.

"Have you learned? Do you know that Grandpa Qin's grafting results can be sold for millions of dollars with just one of them. ”

Zhang Huan said regretfully.

"Would you believe it if I told you that the nutrient solution in that bottle was the most valuable?"

Zheng Qilin said.

“...... I believe. ”

Zhang Huan nodded.

......

After the two came out, they walked along the street for more than ten minutes, and finally returned to the hotel where they were staying.

In this way, until more than three o'clock in the afternoon, Zheng Qilin received a call from Liu Xiaoling, Liu Xiaoling said that she had taken the train and would go to Fengcheng at eight o'clock in the evening, so that Zheng Qilin would come to pick her up at that time. Zheng Qilin said yes, and then hung up the phone.

"Your girlfriend is here?"

Zhang Huan asked.

"No, it's my business partner. That, let's do it for both of us, I'll give you a million WeChat transfer later. As your guide fee for these two days and the overnight fee for last night......"

Zheng Qilin glanced at Zhang Huan and quipped, the dewy relationship between the two should also have an ending.
