China News Service, Chongqing, March 1 (Liang Qinqing) The Chongqing Forestry Bureau revealed on the 1st that as of now, 38 districts and counties in Chongqing have completed 1,598 transect surveys for the census of forest germplasm resources, with nearly 40,000 resources and excellent quality. 838 standard forest stands were surveyed, 4,480 excellent individual plant surveys were completed, 232 rare and endangered species, suspected new species and newly distributed species were found, 15,736 specimens were collected, and the census of forest tree germplasm resources will be completed in 2022. Municipal level acceptance.
According to the Chongqing Forestry Bureau, this census is the first time that Chongqing has carried out a comprehensive census of tree germplasm resources. Germplasm resources census technical expert group, and studied and issued the "Chongqing City Forest Germplasm Resources Census Implementation Rules", identified 118 key census tree species in the city, organized 38 district and county census technical teams and district and county forestry bureau census technicians to organize Special lectures on census technical training, explaining in detail the technical requirements of census.
In the next step, Chongqing will promptly start to formulate a plan for the protection and utilization of forest germplasm resources, vigorously carry out research on the rescue and protection of rare and endangered germplasm resources and breeding technology, and effectively maintain ecological diversity.
In view of the current situation that the afforestation space is declining and the forest quality needs to be improved, Chongqing will make full use of the survey results of excellent forest stands and excellent individual trees, and build a batch of seed collection bases based on local precious timber, characteristic economic forests or high-quality resources of tree species with special ornamental value to meet the needs of The current demand for scientific greening in the city has effectively promoted the precise improvement of forest quality.
At the same time, on the basis of continuing to build the current 7 tree germplasm resource banks, the Chongqing Forestry Bureau will build a batch of comprehensive tree germplasm resource banks to strengthen the collection and preservation of fine tree germplasm resources, so as to provide new resources for the next step. Variety creation and breeding of fine varieties provide abundant genetic materials.
The Chongqing Forestry Bureau will also establish a germplasm resource evaluation and utilization system, implement accurate identification and evaluation of germplasm resources, provide important support for resource collection and conservation and subsequent development and utilization, fundamentally solve the problem of "stuck neck" in provenance, and provide a basis for the realization of the Industry-powerful country contributes forestry power.
