More than ten minutes passed, and the four friends gathered around Grandpa Yuan to listen to the next arrangement.

Grandpa Yuan looked around and said, "There are two options for your practical activities, one is planting, being a little helper for technicians, and selecting vegetables of interest for planting and cultivating; The other is to pick vegetables, work as a little helper for the aunts, and pick vegetables under the guidance of the aunts. ”

When Ding Xuecheng heard Grandpa Yuan's plan, he immediately called Bei Bei in his heart: "Bei Bei, are you there?" How do I choose? ”

"It's here~ It's finally my turn to play a role, haha! If you choose to plant and cultivate, what can you get from picking vegetables? ”

"What is good to plant? I'm going to secretly use the culture liquid and exchange the precious vegetables and herbs I harvest for points! ”

"I've chosen three varieties for you: water chestnut, reishi and ginseng."

"Ganoderma lucidum and ginseng are precious Chinese medicinal materials, and they are definitely worth a lot of points! But how many points can water chestnut be exchanged for? Why not breed Cordyceps? ”

"Ignorance! Do you remember Tian Huangshi at the beginning? What you think is valuable is the value of your real world, and it may not be able to exchange for a lot of points; And what you think is worthless, your technology has not yet been discovered, but it can be exchanged for a large number of points. The essence of Cordyceps sinensis is that it is an insect and an animal, what is the use of using plant culture medium? Can Lord Bebe's guidance be wrong? ”

"I understand a little~...... But what exactly is water chestnut worth? ”

"The plant culture liquid can mutate the water chestnut, and the shell of the mutated water chestnut can be used to ......, you don't have to worry about it, and you will do it according to my instructions, just cultivate it well!"

"Mutation? Water chestnut shells? …… Okay, you can do what you say! Hey? Beibei, how can you interfere with the event this time? ”

"For the sake of my commission, I try to point as little as possible, and it's not a big problem."

"Babe, you are so cunning! But don't 'want money, don't die', I don't want to lose you!" ”

"I'll be careful! Don't worry~ Don't want to move me, I can't lose a single cent of the commission! ”

"You! …… It's too straightforward to ask for points, right? Somewhat brazen too! ”

"Hehe, points are not everything, but no points are impossible!"

“……！”

When Ding Xuecheng and Bei Bei were communicating, the three friends had already thought about it and began to make a choice.

Yeon-yeon raised her hand and said, "I go to pick vegetables, and I often help my mother choose vegetables at home." ”

Kiki also raised her hand and said, "I'm going to dig potatoes, and the baby potatoes in flower clothes are so cute!" ”

Bin Bin touched his fat face and said, "I want to learn edible mushroom cultivation techniques." ”

Ding Xuecheng said tentatively: "I want to plant and cultivate, ordinary vegetables, edible fungi and herbs." Grandpa Yuan, is it okay? ”

"Okay~ It's okay! As long as you observe and learn useful knowledge under the guidance of the staff, you can do it! I and the staff have explained it, and you go to them according to the choices you just made and start your practical activities. ”

Grandpa Yuan said that, and then said to Bin Bin and Ding Xuecheng: "You two little guys, you must follow the guidance of the technician and pay attention to disinfection before entering the cultivation room." ”

"Oh, we know, we'll do it!" Bin Bin and Ding Xuecheng hurriedly assured.

After the three friends left, Ding Xuecheng called out Beibei.

"Bebe, it's unlikely we'll be here for the night, the event will end in the evening at the latest. Time is tight, what to plant first? ”

"Ginseng is the best, go to the ginseng planting greenhouse first."

Ding Xuecheng had been staying in the ginseng planting greenhouse for a long time just now, and he was very familiar with it, so he ran over after a while and found the administrator of the greenhouse.

"Hello, uncle! I'm here to learn about ginseng cultivation. ”

"Oh, children, the ginseng seedlings here are germinated in batches, not cultivated every day, nor are the ginseng seedlings transplanted every day. During this time, my main job is management, and you have asked in detail about the daily management of ginseng? ”

Ding Xuecheng was dumbfounded when he heard this, and hurriedly asked in his heart: "Beibei, do you need to start cultivating from ginseng seeds?" ”

"It's best to start with seed cultivation, and it's best to find wild ginseng seeds."

"Uncle, can you explain to me the process of cultivating ginseng seeds into seedlings?"

"I have finished today's management work, and I am ready to continue to study how to improve the success rate of germination and shorten the germination time, come with me!"

Ding Xuecheng followed the administrator's uncle back to the institute and walked into a laboratory on the second floor. The entrance is an office with a desk on one side and a display table on the other. The display table is a large glass case, like a refrigerator in a supermarket, which is divided into many small compartments, in which seeds of different sizes and colors are placed. Some are shaped like cashew nuts, some like peanut kernels, some like pistachios, and even some like sunflower seeds; Yellow-white, off-white, gray-black, brown, black, and many more.

"Uncle, these are all ginseng seeds? How can there be so many kinds? ”

"There are four major categories of ginseng in the world: Jilin ginseng, Korean ginseng, oriental ginseng and American ginseng. According to the growth mode, there are three kinds of wild ginseng, moving ginseng, and garden ginseng; According to the origin of the name, such as Jilin ginseng, Korean ginseng, American ginseng, stone pillar ginseng, etc.; According to the processing method, such as: red ginseng, white sugar ginseng, raw and dried ginseng, fresh ginseng, active ginseng, etc.; There are also compound names, such as Korean red ginseng, Jilin wild ginseng, Kuandian pillar ginseng, etc. Different types of ginseng have different seeds. ”

"It's so complicated! Uncle, what kind of ginseng seeds are on here? ”

"This is the seed of wild ginseng in Changbai Mountain, no matter how you do it, it can't germinate, and it's scrapped!"

Ding Xuecheng hurriedly asked Bei Bei to come out and asked in his heart: "Bei Bei, are these seeds wasted?" ”

"Scrapped? Cut ~ look at the integrity of the seeds, it should be no problem, they didn't find the right way. ”

"Uncle, can you give me a few of these seeds? Hehe, keep it as a commemorative ...... for this event."

"No problem, there are so many, you can take a few!"

The administrator's uncle said that, he opened the display case and asked Ding Xuecheng to take a few.

"Bebe, how much?"

"You don't have too many points, don't be greedy, just take those pure black, intact and full seeds, seven or eight."

Ding Xuecheng hurriedly selected according to Beibei's guidance, and selected eight of the "discarded" seeds in most of the squares.

"I'm going to have these a few, thank you, uncle!"

The goal was achieved, and Ding Xuecheng didn't want his uncle to teach him the knowledge of seed germination, so he turned around and said goodbye.

"Uncle, I'm going to plant ginseng, and I'll observe the growth of ginseng again."

The administrator smiled speechlessly and muttered, "Grow ginseng? Not to mention that those seeds cannot be germinated, intact seeds will also go through 7~8 months before the seeds will crack and be taken out for sowing. Alas ~ children are messing around! ”

He thought of something, slapped his forehead, and then chased after Ding Xuecheng and shouted: "Children, play in the open space of the experimental field, don't touch those ginseng seedlings!" ”

"Got it, I promise not to touch any ginseng in the field!"
