Because of the high cold and lack of oxygen, strong wind and solid frozen soil, Nagqu, Tibet was once known as the only city in the country without trees. However, this will always be history. For the first time, Nagqu towns were stained with the greenery sprouted from tens of thousands of trees.
Nagqu Why is there an amazing change? Following the survey's perspective of Science and Technology Daily, readers are attracted by the deep answers. There are at least three important factors that have inspired and released the magical power of science and technology, which has changed the city of Nagqu on the plateau.
One is the belief that can only succeed without fail. It's not that the people in Nagqu haven't tried planting trees. However, if we want to break through the five major difficulties: cold weather, ground freezing, thin soil, strong radiation, and excessive wind and wind, there is no ready way to go, and we must continue to break the cognitive barriers-it is impossible to not have the spirit of daring to fight and daring to win. History is made by the brave. indeed so! Years of exploration proves that "planting trees in Nagqu" is a task that can only be achieved by pioneers and an answer that can only be found by the brave.
Second, the full-chain mechanism of "revealing the rankings". Why is it a full chain mechanism? This is because as an open innovation system, "Revealing the List" is not just about solving problems in a certain link. Among them, the most important thing is to coordinate scientific research management and scientific research incentives, adhere to the orientation of effects and results, and mobilize abundant resources and diversified forces. In November 2016, the Ministry of Science and Technology "Thirteenth Five-Year Plan" typical fragile ecological restoration and protection research key special project launched the key technology research and development and greening model demonstration project of urban tree planting in Nagqu, Tibet (hereinafter referred to as the Nagqu project). By revealing the rankings, the Inner Mongolia Kubuqi sand control enterprise Yili Group has successfully launched a challenge to the harsh natural environment of Nagqu in conjunction with a number of scientific research units. From soil improvement, sapling breeding to management and maintenance, in the face of the systematic project of planting trees on plateaus, only multi-unit cooperation and high-intensity investment can ensure that they overcome difficulties and successfully break through.

Third, follow the road which is a green development that respects nature, conforms to nature, and protects nature.Just take the breeding of saplings as an example. In order to make the trees shade, the roots must be taken down first. However, in Nagqu, the time to meet the temperature requirements for the breeding of poplar and willow cuttings is only from June to September, which is less than 100 days, and it is difficult to take root properly. Practice has proved that the seedlings used in Nagqu are best to be propagated in situ in Nagqu, and a suitable small environment is created in Nagqu according to the needs of plant breeding. If you do not respect, respect and conform to nature, it will be difficult to understand the local natural environment clearly, and it will be difficult to systematically find the correct way to solve the problem.
Today, the seedlings of the Nagqu project base have been successfully overwintered, with an average overwintering preservation rate of more than 75%, and the current stock of seedlings is more than 300,000. Only by continuing in-depth investigation and research and conscientiously summing up experience can we continue to innovate in practice, accelerate the transformation of technology and the implementation of results, and make the cities and towns in the vast alpine region full of greenery and vitality.
