Chinese blew the save Xinjiang Tianshan wild fruit forest precious gene pool horn – Beijing, Beijing, September 23 Urumqi Xinhua (reporter Sun Tingwen) Chinese Academy of Sciences, Xinjiang Institute of ecology and geography, party secretary Tian Changyan said 23, hosted by Xinjiang Institute of ecology and geography of the state key development program "Tianshan Mountain wild fruit forest degradation ecological conservation and health regulation" in June this year through the review, officially approved, and will be officially launched in October this year. At the national level for saving the wild fruit forest in Tianshan Mountain precious gene pool horn. 23, for the first time in the form of documentary science focusing on Xinjiang’s Tianshan wild fruit forest "save the gene pool" held film conference here. The documentary is the CCTV Science Channel and Chinese Academy of Science Communication Bureau of Chinese Academy of Sciences, Xinjiang Institute of ecology and geography science cooperation filming a documentary, will be broadcast on CCTV Science Channel in September 26th. Xinjiang Tianshan wild fruit forest as one of the world’s apple, walnut, apricot, plum and other fruit trees. The origin is an important distribution area of natural gene pool Chinese fruit resources in economy. According to the latest survey, 58 species of wild fruit plants of Xinjiang wild fruit forest, where the wild apples are the main edificators, there are 84 types of apple, is the world’s rare natural genetic treasure, important germplasm gene pool is also on the world temperate tree genetic diversity and gene evolution. It is reported that the wild fruit forest in Xinjiang wild apple, is the ancient subtropical broad-leaved forest tree species leaves generation third tertiary relict plant, have important significance in screening and molecular genetic breeding of fine varieties, improved fruit quality of modern economy. "Tian Changyan species rich, lush vegetation, healthy and stable ecological system" to describe the last century in 80s, the wild fruit forest in Tianshan mountain. But because of the last 50 years of human intervention, Xinjiang Tianshan wild fruit forest area decreased by nearly half, and in recent years the outbreak of epidemic diseases and insect pests, large dead trees in the wild fruit forest, Xinyuan County core area of dead rate as high as 80%. Even more frightening is that the Xinjiang wild fruit forest disease spread in area 400 hectares per year. At present, only about 5000 hectares of wild fruit forest in Tianshan mountain. Xinyuan County wild fruit forest improvement station responsible person Pang Jianzhong said, in order to protect the legacy of the medieval wild fruit forest, Xinyuan county has compiled "the wild apple forest protection and restoration project implementation plan", plan 10 years (2015-2024 years) to gradually complete the wild fruit forest protection and restoration work. In the future, Xinyuan county will fully implement grazing and artificial afforestation project. Da Nagasahiko said that in October this year will start the "Tianshan Mountain wild fruit forest degradation of ecological conservation and health control technology", to this day the wild fruit forest resources conservation principle, the key technologies of the wild fruit forest ecosystem degradation of important species population rejuvenation, mining special resistant genetic resources, the creation of new germplasm of agriculture, to provide scientific support for sustainable use of wild fruit resources China.
