In addition to the rose garden, netizens also paid attention to another experimental project of the Biological and Life Sciences Research Center, which is the drought-tolerant plant cultivation project. Netizens found relevant paper materials published by Yang Fang and others, and
I don’t know where I found a video of an experiment. This is a test video. In the video, you can see that a Haloxylon ammodendron plant emerged from the sand like a bamboo, and it can grow to two or three meters high in two or three days.
Adult plant.
Before, everyone thought this was some kind of special effect, but after careful analysis, it was discovered that this was not a special effect at all, but a real video. And relevant papers and materials also verified the authenticity of this video, and this video also
It quickly became popular on the Internet and became a topic of concern to many people.
The reason why it has received so much attention is due to a combination of factors. First of all, let’s talk about the background. Our country has a vast desert and Gobi land. It can be said that desertification is very serious and the natural conditions are harsh.
Over the past few years, under the leadership of the state, basically the whole country has been working hard to return farmland to forest, return farmland to grassland, close mountains for afforestation, afforestation, windbreak and sand fixation, water and soil conservation and other ecological management work.
After these years of hard work, our ecological management work in this area has achieved world-renowned results. We have successfully resisted the expansion of deserts, and achieved anti-communist control of deserts, transforming some previously uninhabited areas full of yellow sand into
It has become an oasis forest with lush water plants and shady trees. We even spent decades successfully conquering a desert and turning a desert wasteland that has been famous for thousands of years into an oasis.
In the past, the sky was full of yellow sand in the north. Under the protection of the Three North Shelter Forest and the comprehensive management over the years, it has gradually decreased and disappeared.
Such achievements are certainly worthy of pride, but while we are proud, we cannot be complacent, let alone relax. Because we are now in a stage of wrestling between the desert and us. If we do not work hard to move forward, we will be hit by the desert and swallow us up.
All previous efforts.
Moreover, our country has vast desert areas. The current control area only accounts for a very small part of the increasingly desertified land. Therefore, the work of afforestation, wind prevention and sand fixation, and ecological management has a long way to go. It can be said that this is
A beginning.
In recent years, under the strong advocacy of the country, people's environmental quality has become higher and higher, and their enthusiasm for investing in environmental protection actions has become higher and higher. Various environmental protection projects have also emerged in an endless stream. In the afforestation of the northwest, this has also
It became a fashion.
Through the popularization of some APPs, everyone has gradually become clear about the plant and tree species planted in the area next to the northwest desert, such as the most common Haloxylon ammodendron, sea buckthorn, masson pine, salix, and some Populus euphratica, etc.
However, the growth rate of these plants is too slow, and the survival rate is not high. Even for Haloxylon ammodendron, which is the easiest to survive, this is still the case, and the growth situation is actually not good. Many people have worked hard to save points to receive seeds.
I picked up a Haloxylon ammodendron and hoped that it would grow into a big tree, even a big fir tree. But in fact, when many people actually looked at it, these Haloxylon ammodendron trees looked like half-dead trees.
The low weeds are very disappointing.
As for Masson pine and Salix euphratica, their growth rate is too slow. During the seedling stage, it is difficult to withstand the wind and sand. It is possible that these seedlings were buried after a sandstorm.
Some areas have tried to plant some fast-growing poplar varieties before, including those used in the Sanbei shelterbelts. However, in recent years, it has been discovered that these fast-growing poplars have various problems.
First of all, this kind of fast-growing poplar tree is relatively short-lived. It basically starts to wither after growing for 20 or 30 years, so it is not suitable for long-term planting. Secondly, fast-growing poplar will produce some lint, which will overflow into trees once spring comes.
disaster, which will cause a series of problems.
For example, in fires, these lint are very light and flammable, floating in the air, just like powder floating in the air. Once there is a little fire, a flashover is likely to occur, and even an explosion will occur in a sealed space. This
It also causes what we call dust explosions.
Secondly, these lint will gradually accumulate into clumps on the ground. These dry lint are natural ignition materials. When encountering a spark, they will flash fire and expand rapidly, leaving no time to stop the fire.
Especially in the northern region, there is drought and little rain in spring, often accompanied by northwest winds. Once Mars encounters, entire tracts of forest land may be ignited and burned to the ground, destroying decades of hard work.
In addition to being flammable, these woolen cloths can also seriously affect human health. Few of them have been discovered before. In recent years, the cases of allergic rhinitis and respiratory diseases related to people in these fast-growing poplar areas have increased a lot. Among them
Allergic rhinitis has increased exponentially, and it has been confirmed that these lint and another desertification control plant, Artemisia annua, have become the biggest culprits.
Therefore, in recent years, under the widespread appeal of local people, the local government has begun to change greening tree species and plants, and stopped planting fast-growing poplars and mugwort.
In addition, this kind of fast-growing poplar has poor resistance to diseases and insect pests, and is prone to large-scale pests and diseases, causing a large number of fast-growing poplar forests to die directly. Therefore, the planting of fast-growing poplar is now no longer recommended or even banned.
So now, whether in academia or desertification control departments, most people actually hope that an excellent windbreak and sand-fixing afforestation tree can emerge. As for the super Haloxylon ammodendron studied by the Haoyu Science and Technology Biological and Life Sciences Research Center,
This gave many people hope, and some even called it the "nemesis" of the desert.
Especially that video went viral online and was quickly forwarded and watched by many people, and was directly sent to relevant departments.
Faced with so many comments from netizens, the official had no choice but to respond.
The official response was also very detailed and specific. They responded that they had contacted the Haoyu Science and Technology Center for Biological and Life Sciences to confirm that the video information was official and that the Super Haloxylon ammodendron in the video really existed.
However, this super Haloxylon ammodendron is still in the experimental stage of breeding, and it was cultivated through genetic engineering. The reason why it grows so quickly is that researchers extracted the moso bamboo gene and implanted it into Haloxylon ammodendron, which gave Haloxylon ammodendron its
It has the same growth rate as moso bamboo, so it grows so quickly. It can grow from breaking ground to a plant two to three meters high in one or two days.
Although the performance of this super Haloxylon ammodendron is very good, it is a genetically modified new plant, because it is not yet certain whether its safety is reliable.
