It is not difficult to solve the problem of high purity oxygen.
It is not difficult to solve these problems by combining decomposition method with shield machine to advance 3 meters a day.
Even granite-grade hard rock decomposition corrosion is no different from ordinary loess layer
Huang Xiuyuan ordered, "As soon as possible, you and China Railway will build a shield machine to test one."
"Chairman, rest assured that China Railway is more anxious than we are, and the shield machine has gone."
Chapter three hundred and seven Species
Zitong County stayed for a moment, and Huang Xiuyuan’s motorcade continued northward through Guangyuan and entered Hanzhong area.
The motorcade came to the vicinity of Qingqiao Post on the north side of Hanzhong.
This seemingly ordinary town hides two very important institutions, Qingqiaoyi, about two kilometers west of the mountain. There is a building group near the mountain and water, and all of them have adopted new materials to build roofs and set up dense solar panels.
Huang Xiuyuan saw another elegant middle-aged man who had not seen Qin Lizhang for several months as soon as he got on the bus.
"Old Qin, long time no see"
Qin Lizhang held out his hand to shake his hand and said with a smile, "Xiu Yuan didn’t expect you to come in person."
"I came to inspect a kind of library and look at the situation of Qinling class."
The "chairman" is an elegant middle-aged man who is a botanist dug up by Fengmin Academy of Agricultural Sciences and is responsible for the construction of Qinling seed bank and species search.
Huang Xiuyuan turned his head and asked, "How is Dr. Lin He’s seed bank built?"
"The first phase of the project has been completed and the second phase is under construction." Lin He answered as he walked.
Huang Xiuyuan and his party came to the first phase of the seed bank project, where 12 professional seed banks were built. All the seed banks were semi-buried, and more than five-quarters of them were embedded in mountains and strata.
This is a doomsday defense level seed bank. Except for solar panels and storage pools, each seed bank has an independent diesel generator set, an independent refrigeration system and an intelligent system.
Strong enough to resist short-range nuclear explosion, the nuclear explosion distance should be 5 kilometers away from the surrounding seed bank, and the annual low-energy operation can be maintained without external energy.
Even without low-temperature freezing and energy, the seeds can still be preserved for hundreds of years.
These are just five large-scale doomsday seed banks in China. In addition to Fengmin Agriculture, Hanzhong Qingqiaoyi Seed Bank, COFCO Qinghai Qilian Mountain Ebao Seed Bank, Beidahuang Daxinganling Seed Bank, and the other two are Taihang Mountain and Dabie Mountain built by the Ministry of Agriculture and the Academy of Agricultural Sciences.
"How many kinds are there now?"
Without thinking, Lin He replied, "In 15735, species or tissues were planted, and on average, there were 3 species of each plant, which would be divided into three different species banks."
Thinking for a moment, Huang Xiuyuan ordered "to increase the collection of wild plants in China, Southeast Asia, Northeast Asia, Central Asia and Siberia in cooperation with the Academy of Agricultural Sciences"
"Chairman, it has always been our direction to protect the genetic resources of wild plants."
"A few years ago, due to industrial development in China, many biological resources were on the verge of extinction. You should be more concerned and try to keep these cherished plant genes as much as possible. Maybe it will be possible in the future."
"It is really very important for the chairman to think deeply about biological genetic resources." Experts in this field naturally know the current situation of the country, and it will be really regrettable if they do not step up protection of these genetic resources until these plants or animals become extinct.
Especially in recent years, many areas have planted genetically modified agricultural products, so the safety of genetically modified agricultural products will not be discussed in depth.
However, genetically modified agricultural products are generally super resistant to glyphosate, and farmers can kill weeds in farmland by spraying glyphosate. In this process, a large number of wild plant resources are killed together.
In addition, the genetic pollution of genetically modified agricultural products. Many people can’t keep genetically modified agricultural products as real organisms. The environmental adaptability of these things is very terrible. They seem to have lost their reproductive ability when they are "transformed", but they are not absolutely castrated.
German scientists directly planted genetically modified agricultural products in foreign farmland, which led to gene crossing between genetically modified agricultural products and related wild plants. This is called genetic pollution.
Genetic contamination was detected in 5% corn, 3% soybean and 3% rape in North America, the core producing area of transgenic technology.
Although the polluted normal species account for 5~1% of the yield, genetically modified agricultural products have been proved to cross genes with related plants.
This situation is definitely not good news for wild plants.
In particular, there are many wild soybean genetic resources in Northeast Asia, the origin of Chinese soybeans. Once genetically modified soybeans are planted in Northeast China on a large scale, the wild soybean resources in Northeast China may face extinction.
Perhaps some people will say that the extinction of wild species will not affect the cultivation of agricultural products, and what wild plants must be worried about.
If you really think so, the banana will say yes.
Back in 195, the most widely planted banana species in the world was called "Big Mike", which was thick, strong, durable and very popular for transportation.
However, a sudden epidemic wiped out the whole "Big Mike" species in a few years.
A fungus named Fusarium oxysporum was the culprit of this banana extinction. At that time, farmers called the disease "Panama disease" or "banana cancer"
Because of the infection with Fusarium oxysporum, Mike banana is a medicine that can be cured. Now we officially call this disease "Yellow Leaf Spot Tropical Type 1"
So what big Mike banana is resistant to Fusarium oxysporum?
The reason is that the big Mike banana is a typical triploid, which is artificially cultivated for sexual reproduction.
The real name of the banana we eat today is "banana with fragrant buds", which is a race cultivated in 1947.
However, banana with fragrant buds also has the fatal disadvantage of Big Mike, that is, once it encounters some deadly bacteria, it is the "neat rhythm of home"
Therefore, the importance of wild species is definitely not only to protect the ecological environment, but also has an important impact on the human table.
Once the genes of wild plants are contaminated by transgenic plants, there will be a large area of assimilation. If you encounter some deadly bacteria, the consequences may be that the whole species will receive lunch together.
Humans may lose a genus directly.
For example, the large-scale cultivation of genetically modified rice in Asia, the origin of rice, will produce genetic pollution to local wild rice.
At present, the promotion of small-scale peasant economic structure in China, without professional technology and isolation greenhouse, will definitely lead to the large-scale extinction of wild species
Therefore, Huang Xiuyuan ordered Fengmin Agriculture to establish a seed bank as soon as possible to protect the genetic resources of wild plants in the country.
Once the gene is extinct, it is very difficult to recover it.
It’s not that Huang Xiuyuan opposes genetic modification, but that he opposes blind genetic modification, especially that promoting genetically modified agricultural products before China has mastered independent genetic modification technology is to give the handle to ABCD.
