针对草莓、生姜、番茄、黄瓜、茄子、辣椒、人参等作物的土传病害问题,经过近20年的国际合作与攻关,中国农业科学院植物保护研究所相关研究团队实现了对上述毁灭性土传病害的温度控制和可持续治疗。(1)研究明确了毁灭性土传病害的病原物主要为镰刀菌、疫霉菌、腐霉菌和青枯菌及根接线虫,建立了土传病原物的分离、检测及鉴定方法,明确了传播规律。(2)研究筛选出高效、无残留、对非靶标微生物干扰可恢复的土壤熏蒸剂:硫酰氟、二甲基二硫、氯
After nearly 20 years of international cooperation and tackling the problems of soil-borne diseases such as strawberry, ginger, tomato, cucumber, eggplant, peppers and ginseng, the relevant research team of Institute of Plant Protection of Chinese Academy of Agricultural Sciences has realized the above- Disease temperature control and sustainable treatment. (1) The pathogen of destructive soil-borne diseases was identified as Fusarium, Phytophthora, Pythium and Ralstonia solani and root-knot nematode, and the methods of isolation, detection and identification of soil-borne pathogens were established. law. (2) Studied and screened soil fumigants with high efficiency, no residue and no interference with non-target microorganisms: sulfuryl fluoride, dimethyl disulfide, chlorine
