[Explanation] In Qinghai, generations of forest and grass people have inherited and guarded the hard-won green waters and green mountains. They have become practitioners of plateau ecological construction with their day-to-day persistence.

Zhang Jinmei, director of the Xining Forestry Research Institute, is one of them.

Zhang Jinmei has been rooted in the plateau for more than 30 years, and has been sleeping in the wild all year round, with an average of more than 200 days of field work per year.

Carrying out hybridization experiments, selecting the most suitable varieties and breeding methods, Zhang Jinmei used her wisdom and sweat to write her own unique "scientific research paper" on the plateau.

　　The Qinghai-Tibet Plateau has such a good and unique natural advantage, so how can we make good use of the natural germplasm resource bank and write the paper on the earth? , Do it every year, month after month, then you may feel that, over time, there will always be something to reward you.

　　[Explanation] In the 1980s, Zhang Jinmei resolutely applied for the agronomy major of Qinghai Agriculture and Forestry School for her dream.

In the early years, in the face of the current situation of "the trees planted every year die every year, and the greenery is planted every year in a wasteland", Zhang Jinmei first started with the selection of excellent drought-resistant tree species, while going deep into the afforestation plot to check the tree species with high survival rate on the mountain, research The main points of soil preparation, water storage and moisture preservation, repeated experiments on methods to improve the survival rate of seedlings; while going deep into the fields, hand-in-hand teaching the workers to pick seeds, sow, pick strips, and cut, and do tree species hybridization experiments.

During the day, I run around the mountains and forests, and at night, I analyze data, find out the reasons, and summarize with my colleagues.

There are few locally bred varieties, so she introduced seedlings from other places to try to find the most suitable breeding method.

　　It is mainly aimed at the selection and breeding of some native tree species in Qinghai (poplar, Qinghai spruce), to solve the problem of a single tree species for afforestation and greening on the Qinghai-Tibet Plateau, so we have been focusing on local native tree species for so many years. , Some foreign tree species are used as embellishments and supplements (functions) in urban greening, and its (foreign tree species) stability cannot meet the needs of long-term sustainable management in all aspects.

　　[Explanation] In addition to studying poplar trees, Zhang Jinmei led the team to travel all over Qinghai to collect and introduce local tree species with drought tolerance, strong adaptability and good ornamental value, and promote and demonstrate after selection and cultivation.

Among them, the lilac, the flower of Xining, is the main object of collection and promotion.

In order to cultivate more varieties of cloves suitable for the special climate of Qinghai Plateau, the team she led has traveled to Qinghai, Gansu, Shanxi, Inner Mongolia and other places, and introduced a large number of high-quality varieties of cloves.

After years of hard work, the number of lilac varieties in Qinghai Province has increased from the initial single digit to 103, and there are 69 varieties that can be bred, and 36 lilac varieties have been recorded on the national lilac germplasm resource collection platform. Xining City has also built China's first lilac national forest tree germplasm resource bank.

The clove cultivation base extends from Xining to the high-altitude areas of Qingnan, which can meet the demand for cloves in the low-altitude to high-altitude areas of the Qinghai-Tibet Plateau.

　　After you go (to) the natural world, you (will feel) there are too many things that can be researched and utilized in the natural world. The longer we (research), the more we feel that there are too many things that we have not done.

I didn't do this, I didn't do that, it's a pity, it's a pity, I feel a kind of regret, as if it's too late.

I always feel (should) race against time to hurry up some things and time, and want to do this.

　　[Explanation] Zhang Jinmei once said that in work, you must be brave, dare to try, and be responsible. The more you have the spirit of seeking truth and pragmatism, the more confidence you have to start a business.

Today, as the city flower of Xining, the number of lilacs planted accounts for 70% of the total number of flowers and shrubs planted in Xining.

Xining has become one of the cities with many varieties of lilacs and a large planting area in China, and has become a veritable "city of lilacs".

　　The next step is to make better use of it on the basis of collection and protection (germplasm) and make use of it (germplasm bank).

Then there are so many germplasms to lay a germplasm foundation for the next hybridization and breeding of better varieties, suitable for the Qinghai-Tibet Plateau.

　　[Explanation] Zhang Jinmei's more than 30 years of perseverance and steadfastness have made her green dream come true.

Zhang Jinmei said frankly that although she has done a lot of work in the past 30 years, she always has a sense of mission that has not been completed.

She hopes to continue to stay on the front line of scientific research in the future, cultivate more tree species suitable for planting in Qinghai, and make green the most beautiful background color of the Qinghai-Tibet Plateau.

　　We still need the continuous struggle from generation to generation and continue to work hard to protect and make good use of the germplasm resources of our Qinghai-Tibet Plateau.
