"Therefore, orchids generally use dragon root tissue culture and bud point tissue culture, which is the second way to reproduce natural orchids. ”

"The dragon root tissue culture method first cuts the dragon root with buds from the mother parent according to the different species of the product, and then cultivates more dragon roots on the medium, and then cuts more and more seedlings again;"

"The method of bud point tissue culture is to cut the bud points on the head of the orchid reed under aseptic operation, make it grow dragon roots on the medium, and then cut the dragon roots to obtain more quantity, which can also be cut many times, and finally cultivate real seedlings on the dragon roots for transplanting. ”

"Then the problem comes, the growth of orchid roots and shoots in nature must be accompanied by probiotic flora, and the first level of tissue culture is sterilization. ”

"Dragon roots and sprouts are inherently fragile and cannot be soaked and sterilized like seeds, and even too long rinsing time will cause dragon roots and sprouts to die. ”

"But once the sterilization is not in place, the harmful bacteria, after being moved into the culture cup, will multiply in large quantities, directly leading to root rot, which is called 'browning' in professional terms. ”

"If there is 'browning', that group of orchid seedlings will be destroyed, and if left unchecked, the last cup of orchid seedlings will all be browned. ”

"There is also the process of sterilization itself is a process of harm, regardless of good and bad bacteria, they are all killed. After the sterilized dragon roots and buds are moved into the culture cup, there will be a slow growth and recovery process, and many dragon roots will not recover, and they will also die. ”

"Even if you try your best to get the seeds and sprouts cultivated in a sterile environment, they are generally malnourished and have low disease resistance, and then you have to open the lid of the cup for adaptive training, gradually cultivate robustness, and then go through rewilding training to get the actual seedlings that can be transplanted into Lanpu, and finally breed the finished orchid. ”

"There will be countless deaths and eliminations, and many black-hearted sellers will sell the eliminated bluegrass to customers, which is one of the reasons why tissue culture grass is not welcomed in China. ”

"So in general, 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 more ways in this, forming an excellent cultivation technology system, I have been exploring for decades, but I still dare not say that I have figured it out!"

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

Lin Wangcai laughed and said: "If I want to have that ability again, I am Yuan Longping in the orchid world, and all the green grass in the park does not need to be planted with wheat and black bean grass, and it is directly replaced with orchid grass." Then go to the world's major orchid farms to collect good products, set a small goal, phalaenopsis alone, earn him 100 million a year! Hahahaha!"

After laughing, Lin Wangcai said: "But you can't underestimate the tissue culture of orchids because of this, this is a matter of probability, under the traditional cultivation technology, a plant of orchid grass can be divided into a few seedlings at most a year, and tissue culture is to massively expand the cultivation base, a dragon root can be divided into dozens of hundreds of seedlings, even if half of them die, then you can get dozens of real grasses, which is not comparable to traditional cultivation technology." ”

Li Junge thought about the advantages of the space, and said: "I just heard you say that Chinese orchid seeds are generally not easy to germinate, if I can find suitable seeds and fruits for you, can you organize and cultivate them?"

Lin Wangcai said: "I didn't make it clear just now, the fruit of the orchid is the capsule, commonly known as 'orchid'. After the fruit matures in six to twelve months, the skin finally turns brown, and the ripe capsule will crack on its own, sputtering 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 embryo development of orchid seeds and the lack of endosperm, the germination power of orchid seeds is extremely low, and they basically cannot germinate under conventional conditions. However, since we have the conditions for a scientific research laboratory, we can also try it. ”

Li Junge said with a smile: "Then we will do it, the budget of your group training room is more than 100,000 yuan, we will grit our teeth and get it down, if it succeeds, hahaha, it is really possible to see you use bluegrass to spread Lijiagou all over." ”

Lin Wangcai shook his hand again and again: "Don't dare to think about this, let's plant the dendrobium first, and then explore it step by step." ”

Li Junge said: "By the way, there is an agricultural technology station in our village, the stationmaster is called Wu Zhiqiu, that kid also likes to engage in agricultural scientific research, when to call together you know each other, in recent years, the township of lychee seedlings, mulching, I raise fish, bamboo rats, wild geese, are inseparable from his guidance, when the time comes, let him find it through the line of the Agricultural Bureau, and then I will run the line of Director Wang of the Forestry Bureau, to see if I can get the technology of orchid seed tissue culture." It's good to be able to point in the right direction. ”

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

Inspired by Lin Wangcai's words, Li Junge had a strong interest in orchids, and used to just appreciate the flowers, although he had seen a few Wuxi Xianhuang and Bibo Jade Dragon fruits, but he never thought that orchids could be propagated by tissue culture through fruits.

Wuxi Xianhuang is a spring orchid, Bibo Yulong is Xia Hui, according to Lin Wangcai, the fruiting period is half a year to a year, that is, the orchid fruit may ripen in one day on the island.

There was no way to do it, Li Junge decided not to sleep tonight, and would stay for twelve hours first.

Cutting into the space to check the results of Wuxi Xianhuang and Bibo Jade Dragon, it was found that each of them had six or seven fruits.

The blue wave jade dragon was placed on the top of the Qingmin stone warehouse in the space and land, Li Junge didn't care about it first, and went to guard the Wuxi Xianhuang on the island first.

At one o'clock in the evening outside time, the first Wuxi Xianhuang orchid finally burst open, and the orchid seeds like smoke and mist floated away.

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

Then cut out the island, wait outside for the next lanson to burst, and then cut in again to take the most ripe one.

After repeating this, the three Wuxi Xianhuang fruits that were closest to ripe were finally obtained.

Then he moved the Jade Dragon to the island, and did the same to get the fruits of two Jade Dragons.

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

Looking at the five fruits in his hand, Li Junge's confidence almost disappeared, with the spiritual environment of space, Wuxi Xianhuang was planted on the island for two months, which is equivalent to sixty or seventy years of natural reproduction, and only a few dozen plants were reproduced, basically all of them were separated from the buds, the seeds germinated and grew, and a slap could be counted.

In the outer land, the jade dragon is even less bred, and there is not a single plant that sprouts by seeds.

"Nature is so cruel. Li Junge thought about the sunfish and coral reefs that ovulate wildly into the sea every year, and their populations are still not optimistic.

When I went out to wash, I saw that Grandma Lin had already gotten up, had already made breakfast, and was picking up osmanthus flowers with a small flower hoe there.

Lin Wangcai had also gone to Lanchang to go around and came back, and said: "It's still a rural baby! I got up so late, it's all a problem brought back from the big city! Hurry up and finish eating, and go to the city to pull equipment after eating, the fruit of Dendrobium has begun to ripen, and it can't be delayed!"

Li Junge rolled his eyes in his heart: "Lao Tzu was busy in the space all night last night, you just don't know!"

Breakfast is actually pasta, scallion oil and pork buns! This is very rare in Lijiagou, Li Junge praised Grandma Lin: "Oh, you can actually have big buns to eat! Grandma Lin, where did you learn the craft? Our noodles in Lijiagou are generally wheat chicken soup, and at most one pepper leaf cake and scallion oil cake will be finished! Wow, this steamed bun tastes so good!"

Grandma Lin pursed her lips and smiled: "If you like, eat two more, there was a big collective noodle shop in Jiachuan at the earliest, the main thing in it was scallion oil big bags with winter melon soup, and there was cuttlefish stewed chicken noodles, I worked in it for a few years, and these skills were learned at that time." ”

As soon as he said this, Li Junge remembered it and said, "Is it the one from the pier at the north gate?" I said that this steamed bun tastes so familiar! It must be that one, right?"

Grandma Lin said, "Yo! Do you remember this?"

Li Junge said: "Just kidding, why don't you remember! Every year at the beginning of school, my dad sent me over to eat once, and when I was promoted from primary school to middle school, I took the third place in the grade, and my dad was happy, so he took me to the small shop and said that I would open it up to eat, but I ate seven of these big buns in one go, and almost made my dad have no money to buy a ferry ticket back." ”

Grandma Lin smiled happily: "Hahaha, you were only ten years old at that time, right? The rural baby is so powerful, the two babies in the city can't eat it, and the second one has to eat the stuffing and the adults eat the skin." ”

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

Grandma Lin said: "Alas, the store was later contracted, and then the Binjiang Road was repaired, and the place was gone, so the owner of the contracted store changed the place, and took the opportunity to open a few of our old ones, leaving only a few young people, but later I heard that it also collapsed." ”

Li Junge said: "It deserves it, originally such a store was supported by old craftsmanship, and when the old man was opened, this craftsmanship was gone." By the way, Grandma Lin, you are also good at making cuttlefish stewed chicken noodles? We don't put anything in Lijiagou stewed chicken, why don't I go to the county seat today and bring some dried cuttlefish back, stew a pot of chicken, and eat cuttlefish stewed chicken noodles tomorrow morning?"

Grandma Lin smiled: "As long as you like it, then get it, it's not that difficult!"

Li Junge smiled so hard that he couldn't see his eyebrows: "Okay, well, I really didn't expect that the good taste that I was familiar with when I was a child actually settled down in my Lijiagou! I remember that there are still a few signature noodles!"

Grandma Lin said: "At that time, our store business was very good, and there were chicken soup and noodles, beef knife noodles, dandan noodles, small noodles, and burning noodles. ”

Li Junge said: "You will do all this?"

Grandma Lin said: "Yes, I've been doing it for more than ten years, so I won't see it too." ”

Li Junge laughed: "Ouch, that's really a treasure!

Lin Wangcai couldn't look at it: "I know how to eat and eat all day long! Hurry up to the dock, it's time to sail!"

Junding will break 1,000 in the past few days, Lao Zhou simply made three changes in advance, just in time for the holiday... Now one watch, two watches in the evening, I wish you all a happy holiday!
