Chapter 195 The Advantages of Technology
Chapter 190 Six Advantages of Technology
"So orchids generally use the dragon root tissue culture method and the bud point tissue culture method, which is the second reproduction method that simulates natural orchids."

"The dragon root tissue culture method first cuts out the budding dragon roots from the female parent according to the different varieties, and then cultivates more dragon roots on the medium, and then cuts again to get more and more dragon roots. seedling;"

"The bud point tissue culture method is to cut the bud point on the reed head of the orchid under aseptic operation, make it grow dragon roots on the culture medium, and then cut the dragon root to obtain a larger number. This work can also be cut multiple times. points, and finally the seedlings are cultivated on the dragon roots for transplanting."

"Then the problem is that the growth of orchid dragon roots and buds in nature must be accompanied by a probiotic flora, and the first step in tissue culture is sterilization."

"Dragon roots and buds are inherently fragile, and it is impossible to soak and sterilize like seeds. Even if the washing time is too long, the dragon roots and buds will die."

"But once the sterilization is not in place, the harmful bacteria will multiply in large numbers after being transferred into the culture cup, directly causing root rot. The technical term is 'browning'."

"When 'browning' occurs, the group of tissue cultured orchids will be ruined. If left alone, the whole cup of orchids will be completely browned in the end."

"Also, the sterilization process itself is a harmful process. Regardless of good or bad bacteria, they are all killed. After the sterilized dragon roots and buds are transferred into the culture cup, there will be a slow growth recovery. In the process, many dragon roots will not be able to recover, and they will also die."

"Even if we try our best to get the seed sprouts cultivated in a sterile environment, they are generally malnourished and have low disease resistance. After that, we need to uncover the lid of the cup for adaptive training, gradually cultivate robustness, and then go through wild training to get The seedlings that can be transplanted to Lanpuli will eventually grow into finished orchids."

"There will be countless deaths and eliminations during this process. Many unscrupulous sellers will sell the eliminated bluegrass to customers. This is one of the reasons why tissue cultured grass is not popular in China."

"So generally speaking, the tissue culture technology of Chinese orchids is not as simple as that of Dendrobium, and it is impossible to expand the seedlings of hundreds of thousands of plants a year. There are too many ways to form an excellent cultivation technology system. I have explored For decades, I still dare not say I have figured it out!"

Li Junge scratched his head and said, "I thought you would make such a bold statement and cover my Lijiagou with orchids!"

Lin Wangcai laughed and said, "If I had that ability, I would be Yuan Longping in the orchid world. There is no need to grow Ophiopogon japonicus in all the parks, and they can be replaced with orchid grass. Then go to the orchids all over the world. Collect good products in the field, set a small goal, Phalaenopsis alone, earn him one billion a year! Hahahaha!"

After laughing, Lin Wangcai said again: "However, you can't underestimate the tissue culture of orchids just because of this. It is to massively expand the number of culture medium, and one dragon root can produce dozens or even hundreds of seedlings, even if half of them die, you can still get dozens of seedlings, which is beyond the reach of traditional cultivation techniques.”

Li Junge thought about the advantages in the space, and said: "I just heard from you that Chinese orchid seeds are generally not easy to germinate. If I can find suitable seeds for you, can you grow them?"

Lin Wangcai said: "I didn't make it clear just now. The fruit of orchids is a capsule, commonly known as 'Orchid Sun'. After the fruit matures for six to twelve months, the peel will eventually turn brown, and the mature capsule will crack by itself. , Splash the seeds out. The seeds in each fruit are as many as hundreds of thousands or even millions, as fine as dust. Due to the incomplete development of the embryo of orchid seeds and the lack of endosperm, the seeds of orchids germinate The planting force is extremely low, and it is basically impossible for seeds to germinate under normal conditions. However, since we have the conditions of a scientific research laboratory, we can also try it, whether there are dates or not. "

Li Junge smiled and said: "Then we will do it. Your tissue training room has a budget of one hundred thousand yuan. We grit our teeth and get it down. If it succeeds, hahaha, it is really possible to see you using orchid grass to kill the Li family. The ditch is full."

Lin Wangcai shook his hands again and again: "I dare not think about this, I'd better plant the dendrobium first, and then explore step by step."

Li Junge said again: "By the way, there is an agricultural technology station in our village. The station manager is Wu Zhiqiu. That kid also likes to do agricultural research. When will you call me together? Do you know each other? In the past few years, the lychees in the village have been replaced by seedlings and covered with plastic film. , I can’t do without his guidance in raising fish, bamboo rats, and wild geese. When the time comes, let him look for it through the line of the Agriculture Bureau, and then I will go to the line of Director Wang of the Forestry Bureau to see if I can I can't get the technology of tissue culture of orchid seeds. It would be good if I can give some pointers."

The two made an appointment to go to the county seat tomorrow to pull laboratory equipment, so Li Junge went to sleep in his room on the pig farm.

Inspired by Lin Wangcai's words, Li Junge became very interested in orchid sunsun. He used to just appreciate flowers. Although he had seen a few plants of Wuxi Xianhuang and Bibo Yulong bear fruit, he never thought that orchids could be grown. Tissue culture propagation by fruit.

Wuxi Xianhuang is Chunlan, and Bibo Yulong is Xiahui. According to Lin Wangcai, the fruiting period is half a year to a year, that is, within one day on the island, the orchid fruit may mature.

There was no other way, Li Junge decided not to sleep tonight, and to wait for twelve hours first.

Cut into the space to check the results of Wuxi Xianhuang and Bibo Yulong, and found that each has six or seven fruits.

The Bibo Jade Dragon was placed on the top of the Qingmin stone warehouse in Space Dadi. Li Junge ignored it and went to guard the Wuxi Xianhuang on the island.

Staying outside until one o'clock in the evening, the first orchid sun of Wuxi Xianhuang finally burst open, and the orchid seeds drifted away like smoke.

Li Junge immediately cut into the island and picked the most ripe unpopped fruit.

Then cut out the island again, wait outside until the next orchid sun burst, and then cut in to get the most mature one.

After repeating this process, three Wuxi Xianhuang fruits that are closest to ripeness are finally obtained.

Then the Bibo Yulong was moved to the island, followed the same method, and two Bibo Yulong fruits were obtained.

Cut out the space, only to find that the sky is already bright.

Looking at the five fruits in his hand, Li Junge's confidence almost disappeared. With such a spiritual environment, Wuxi Xianhuang was planted on the island for two months, which is equivalent to six to seventy years of natural reproduction, and only a few dozen were bred. Plants are basically separated from the buds, and the seeds germinate and grow, and you can count them with a slap.

The Bibo Yulong was bred even less on the outside land, and there was not a single plant that germinated from seeds.

"Nature is so cruel." Li Junge thought about sunfish and coral reefs that ovulate wildly into the sea every year. With such a way of life, their population numbers are still not optimistic.

When I went out to wash, I saw that Grandma Lin had already woken up, had already made breakfast, and was picking up sweet-scented osmanthus with a small flower hoe.

Lin Wangcai has also gone to Lanchang and came back, and said: "It's still a rural child! It's a problem brought back from the big city to wake up so late! Hurry up and finish eating, and go to the city to pull equipment, Dendrobium The fruit has already begun to ripen, there is no delay!"

Li Junge lowered his head and gritted his teeth: "I worked all night in the space last night, you just don't know it!"

Breakfast is actually pasta, pork buns with scallion oil!This is very rare in Lijiagou. Li Junge praised Grandma Lin: "Oh, there are big buns to eat! Grandma Lin, where did you learn the craft? Our pasta in Lijiagou is usually wheat chicken soup. A pepper leaf pancake and scallion pancake will finish the job! Wow, this steamed stuffed bun tastes so good!"

Grandma Lin pursed her lips and smiled straight: "If you like it, eat two more. At first, there was a large collective noodle shop in Jiachuan. The main products in it were scallion oil buns with winter melon soup, and cuttlefish stewed chicken noodles. I worked there a few times. Years, these skills were learned at that time."

As soon as Li Junge remembered it, he said, "Is it the one from the North Gate Wharf? I said that the steamed stuffed bun smells so familiar! It must be that one, right?"

Grandma Lin said, "Hey! Do you still remember this?"

Li Junge said: "I'm just kidding, why don't I remember! Every year when school starts, my dad sends me there to eat once. When I went from elementary school to middle school, I passed the grade No. 3. When my dad was happy, he took me to that small shop." , said to let me eat it openly, but I ate seven of these big buns in one go, almost leaving my dad with no money to buy a boat ticket to come back."

Grandma Lin smiled happily: "Hahaha, you were only in your teens at that time, right? The kids in the countryside are so good, the two kids in the city can't eat it anymore, and the second one has to eat stuffing and adults eat skin."

Li Junge said: "By the way, why didn't that store open later?"

Grandma Lin said: "Well, that store was contracted later, and after Binjiang Road was repaired, the place disappeared, and the owner of the contracted store changed to another place, taking the opportunity to open us old ones, leaving only It killed a few young people, but later I heard that it also collapsed."

Li Junge said: "It deserves it. Originally, this kind of shop is supported by old skills. If the old man is opened, this skill will be gone. By the way, Grandma Lin, you are also good at making cuttlefish stewed chicken noodles? What about our Lijiagou stewed chicken? Don’t let it go, why don’t I go to the county today and bring back some dried cuttlefish, stew a pot of chicken, and eat cuttlefish stewed chicken noodles tomorrow morning?”

Grandma Lin smiled and said, "As long as you like it, then do it, it's not too difficult!"

Li Junge couldn't see his eyes with a smile: "Okay, okay, I didn't expect that the good taste I was familiar with when I was a child, actually settled down in my Lijiagou! I still remember a few signature noodles!"

Grandma Lin said: "At that time, our shop's business was very good, and there were chicken soup Chaoshou, beef sliced ​​noodles, Dandan noodles, small noodles, and burning noodles."

Li Junge said: "You know all these?"

Grandma Lin said: "Yes, I have been working for more than ten years, and I will watch the meeting if I don't."

Li Junge laughed loudly: "Oh, that's really a treasure! Now I'm confused, which one should I eat first?"

Lin Wangcai couldn't stand it anymore: "I know how to eat and drink all day long! Go to the pier quickly, the boat is about to sail!"

　The average is set to break the thousand mark in these few days, and Lao Zhou might as well make it three shifts earlier, just in time for the holidays... These are all the support you have always had!One update now, two updates tonight, I wish you all a happy holiday!
