The project “Construction and Breeding of Schima superba†presided over by assistant researcher Zhang Rui of the Institute of Asian Forestry Research collected nearly 1,000 excellent tree germplasm in the main distribution areas of Schima superba, constructed a core germplasm bank, and clarified the nutritional growth and reproduction of Schima superba Development and other related characteristics and mechanisms have broken through the breeding techniques of Schima superba, seed garden construction and high yield, tissue culture rapid propagation, container nursery, etc., effectively supporting the large-scale breeding of Schima superba, successfully achieving both sexual and asexual breeding of Schima superba way to go superba seed of the road.
The project “Team Breeding and Breeding and High-Efficient Propagation Technology†chaired by researcher Liang Kunnan of the Institute of Thermal Forestry created a multi-form germplasm resource collection, preservation and evaluation technology system, which broke through the comprehensive selection and evaluation of improved varieties and multi-objective breeding and the directional growth of different types of seedlings Seedling cultivation technology integrates tissue culture rapid propagation, tender branch cutting propagation and light matrix plug tray industrial clone breeding technology system, which solves the problems of narrow genetic foundation of teak in China and serious shortage of improved varieties.
The “Recovery Mechanism and Regulation Technology of Disturbance of Pinus sylvestris var. Mongolica Forest in Sandy Land†chaired by Shi Zhongjie, deputy researcher of the Institute of Desertification, clarified the mechanism of fire disturbance to promote the succession of Pinus sylvestris var. The response law of extreme drought has clarified the disturbance regeneration mechanism of Pinus sylvestris var.mongolica forest in sandy land, and constructed a technical system for restoration and management of ecological disturbance of Pinus sylvestris var.mongolica forest on sandy land, providing reliable technical support for restoration and management of Pinus sylvestris var.
The project “Construction and Application of China ’s Forest Certification Technology System†presided over by Xu Bin, a researcher of Kexin Institute, established a forest certification system framework that conforms to national conditions and is in line with international standards. It proposes the development path and mechanism design of China ’s forest certification and builds China ’s forests. certification standards, to achieve the systematic integration of a forest management certification standards and technical requirements, to promote China's sustainable forest management from theory to practice, and effectively safeguard and promote the rapid development of international trade in forest products.
Researcher Xu Junming, a researcher of the Institute of Forestry and Chemical Engineering, led the project "Research on the Fundamentals and Key Technologies of Plasticizer Materials for the Joint Production of Forestry Oils and Energy", which broke through the engineering of high-acid oils and fats by continuous transesterification coupled transesterification to produce biodiesel. Key technologies such as efficient separation of sensitive viscosity reduction and flash evaporation, coupling of autothermal directional cracking-rectification to prepare hydrocarbon-rich fuel oil, and preparation of high flash point bio-based epoxy plasticizers have further promoted biomass resources in energy and bulk An effective alternative to fossil resources in the field of chemicals.
The project "Research on Biological Control Technology of Forest Spotted Dry Pests and Spotted Beetles" presided over by Professor Yang Zhongqi of Senhuan Senbao Institute carried out basic research on the ecology, behavior and biology of the main natural enemies of Spotted Beetles, and on this basis, Carried out the research on the mass reproduction technology of natural enemies and the biological control technology research of Ceratopis nigra, and carried out the demonstration and promotion of the biological control technology, and achieved remarkable control effect and continuous control effect, and produced good social and environmental benefits.
Third prize (4 items):
The project “Key Technologies for the Construction and Function Enhancement of Coastal Shelter Forest System in the Yangtze River Delta†chaired by Yu Mukui, a researcher of the Institute of Asian Forestry, proposed a spatial pattern optimization technology and optimization plan based on the area, composition and protective function of the shelter forest, breaking through the subtropical muddy tidal flat The technical difficulties in the construction of the dissipation forest in the mangrove forest distribution area have developed a protection forest structure control technology that integrates density control, canopy structure control and vertical structure optimization technology, effectively maintaining the ecological safety of coastal areas and improving the quality of human settlements.
Mori Mori ring researcher Paul Liddy strong over the "China biological specimens resource sharing platform nature reserve" project, through the development of biological specimens and resource standards Nature Reserve, fully integrated biological specimens in the Natural Preserve and the establishment of biological resources sharing platform Nature Reserve so that results of the project to promote the use of multiple nature reserve provides a wealth of science materials for the public, to promote China's scientific and technological, economic and social development and make a positive contribution.
