Basic research: He has presided over the topic "Isolation and Functional Identification of Tree Stress Resistance and Insect Resistance Genes" in the National 973 Project "Research on Molecular Basis of Tree Breeding", and screened plants containing plant thiol protease inhibitors and For the insect-resistant gene resources of plant lectins, my country's unique insect-resistant tree species Populus tomentosa was selected. Two full-length genes of Populus tomentosa thiol protease inhibitors were cloned. The gene expression products were verified to kill beetle-killing functions, and the Robinia pseudoacacia seed lectin was identified. The mechanism of lethal action on gypsy moth larvae; he has chaired the National Natural Science Foundation project "Study on the molecular genetic diversity and adaptive evolution of tree canker pathogenic fungi" and "Study on the genetic diversity and molecular system of tree canker pathogenic fungi" ", taking large groups of tree branch cankers as the research object and finally forming a research system, using molecular biology technology to establish a molecular system that detects, describes and explains the diversity of organisms at the molecular level and their evolutionary rules. The research results prove the objectivity of the traditional classification status of the main genera at the molecular level and the differentiation types within species due to geography and host; he once chaired the D-type fund project for returned overseas students funded by the Ministry of Personnel, "Research on the taxonomy of foreign basidiomycete fungi in China" "(funded twice in a row), we have mastered the distribution, host, and damage symptoms of this genus of fungi in China. The traditional morphological research and molecular biology research results of the strains have initially shown the kinship of the basidiomycetes in China and their impact on host plants. Pathogenicity differentiation; and it was found that 4.3×106Da dsRNA virus was commonly found in each tested strain, which may be related to the pathogenicity of pathogenic fungi to host plants and the occurrence ecology of plant diseases.
In terms of applied research: He has presided over the national 863 project project "Research on Ecological Control Technology and Products for Major Pests and Pests of Planted Forests in Ecologically Fragile Areas of my country", focusing on major plant diseases and insect pests and arid semi-arid diseases in my country's main ecologically fragile areas. For host-dominated diseases in arid areas, we conduct research on disease control technologies and products based on bioinformatics and chemical ecology, research on disease control technologies and products based on coupled optimization of the root system-rhizosphere microecological environment, and research on disease control technologies and products based on optimizing the forest stand biodiversity structure. Research on disease control technology and models, developed a product that can continuously control host-dominant diseases in arid and semi-arid areas of my country - poplar disease-resistant health care agent, and obtained an invention patent; he has presided over the "Tenth Five-Year Plan" research project "Quarantine of major forest diseases and insect pests" "Research on pine wood nematode quarantine and early warning technology", which mainly studies pine wood nematode quarantine and early diagnosis technology, risk analysis and pattern recognition of pine wood nematode disease and red beetle, and space remote sensing monitoring technology of pine beetle; as a sub- The person in charge of the project has participated in the "Tenth Five-Year Plan" key research project "Research on Ecological Control Technology of Major Forest Diseases and Pest Disasters". In response to host-dominant diseases represented by canker and rotten skin disease, the stress resistance differences of individuals or groups of forest trees are used to Study the disease prevention and disaster control effects of different silvicultural management and protection measures, study the improvement of root-rhizosphere microbial flora and microecological environment, and improve the stress resistance of forest trees and the disease resistance of forest stands; as a sub-project leader, he participated in " The key project of the Tenth Five-Year Plan is "Research on Environmentally Coordinated Pesticides for Forestry Pests and Diseases and Their Aerial Spraying Technology" to study the insecticidal spectrum and insecticidal efficiency of plants such as neem and wolfberry, and conduct artificial production of plant-derived pesticides based on cell suspension culture technology. Pesticide research; has presided over the introduction of the 948 project of international advanced agricultural science and technology "New technology for forest pest control-Alamo production technology and application technology introduction", introduced and improved the Alamo locking pressure type trunk micro-injector from the United States, obtained a patent, and is currently starting Produced in small batches in China for prevention and control trials; has presided over the key science and technology project of the Ministry of Science and Technology "Research on Early Monitoring and Comprehensive Prevention and Control Technology of Pine Wood Nematode Disease", and studied the monitoring and prevention technology of pine beetle attractant, pine wood in Huangshan Scenic Area Nematode risk assessment; has presided over the State Forestry Administration’s emergency project “Research on Effective and Continuous Control Technology of Canker Disease on Urban Greening Trees such as Willow, Ulmus, Poplar and Other Urban Greening Trees” and the Ministry of Science and Technology’s Special Fund Project “Research on Prevention and Control Technology of Poplar Canker Disease and Canker Disease”.
In recent years, Researcher Zhang Xingyao has published dozens of papers in domestic and foreign journals. Among them, the 2005 paper "Research on Molecular Genetic Diversity of Tree Canker Pathogenic Fungi Groups II" was rated as the outstanding journal of the third China Association for Science and Technology Academic papers; published two monographs: "Ecological Mathematical Methods for Forest Pathology Research". China Forestry Press. 1999, "Major Biological Disasters in China's Forests". China Forestry Press. 2003; Served as an editorial board member of magazines such as "Forestry Science", "Forestry Scientific Research", "China Forest Diseases and Pests" and "Plant Quarantine"; In 1999, he won the fourth "Professor Liu Yejing Award Fund"; In 1998, he was selected into the former Ministry of Forestry A cross-century academic and technological leader; in 2004, he was selected into the first batch of national candidates for the New Century Talents Project by 7 ministries including the Ministry of Personnel; in 2007, he received a special allowance from the State Council.
