Chrysanthemums were first successfully cultivated on the "roof of the world"

Xinhua News Agency, Nanjing, November 6 (Reporter Dong Jun) Garden chrysanthemums for the first time in the "roof of the world" on the Qinghai-Tibet Plateau - Nanjing Agricultural University researchers have successfully used this chrysanthemum for viewing and greening in the Chaidamu Basin in Qinghai Province for dew cultivation and natural wintering.
this is the reporter recently learned from Nanjing Agricultural University. According to
Wu Juyou of the School of Horticulture of Nanjing Agricultural University, the distribution range of chrysanthemums under natural conditions is less than 1600 meters above sea level, and the highest elevation of cultivated dew chrysanthemums also stops at 2300 meters. This time at an altitude of 3000 meters in the Chaidamu Basin successfully cultivated garden chrysanthemums, a new high altitude record for chrysanthemum cultivation, is a recent achievement of chrysanthemum research in China.
researchers have been testing species in Ulan County, Haixi County, Qinghai Province, since last year. After overcoming the large climate differences and variety adaptability differences, 100 of the 151 chrysanthemum varieties were suitable for local natural conditions. The researchers screened the Jinling series of chrysanthemums, as well as "South Agricultural Green" "South Farm Wasp Nest" and other chrysanthemums can be well adapted to the local natural environment.
Wang Haihai, the project leader and an associate professor at Nanjing Agricultural University, said that in addition to ornamental varieties, tea chrysanthemum varieties such as emperor chrysanthemum and golden silk
also performed well in the local area, with key ingredients such as chlorogenic acid and wood rhinoceros glycoside several times higher than the pharmacopeia standard. As the local winter temperature reached minus 20 degrees Celsius, chrysanthemum aphids can not naturally winter, so pests and diseases are very light.
on the basis of researchers working out a set of technical standards suitable for local cultivation, chrysanthemum cultivation and processing in Ulan County has become a new characteristic rich people's industry. According to Wulan County Deputy County Chief Du Jinbing, the local chrysanthemum-scale planting area has 30 acres, can provide about 500 people a year, each person about 150 yuan a day income. He hopes to provide an effective way for local farmers and herdsmen to get out of poverty by developing the chrysanthemum industry.
history of chrysanthemum research at Nanjing Agricultural University has been more than 70 years, and the China Chrysanthemum Resource Preservation Center has been built, with more than 5000 chrysanthemum resources preserved, ranking first in the world.
