The research of sugarbeet root rot in china was reviewed and summarized in pathogenic germs , host , pathogenesis , control of agriculture and biochemistry 摘要对甜菜根腐病的病原菌、寄主、致病因子、农业防治、生物化学防治等研究成果进行了综述。
General drooping of the entire plant . . . crown , stem or root rot - caused by overwatering , especially during the winter months when plants are dormant and do not need much moisture 整株植物打蔫. . .顶部、茎部或根部腐烂,浇水过多造成,冬天植物处于休眠期,我需要太多水分。
The preliminary research showed that the symptom of soybean root rot could be caused by metabolic product in the soil under the condition of given consistency , and the soybean growth sickness could be caused 初步说明了在土壤中病原菌代谢产物达一定浓度的条件下可导致大豆根腐症状,造成大豆生长障碍。
Sudies on the trannsmission of phytophthora root rot of soybean had been carriedout with the soil debris and the seeds which came from natural diseased fields as well as thesoil and seeds which inoculated with the pathogen 对带菌土壤、病残体进行传病试验,研究了人工接种条件下种子带菌条件及带菌种子传病情况,结果表明,带菌土壤和病残体无论是在当年还是越冬后都可有效地传播大豆疫霉根腐病,是大豆疫霉根腐病的主要初侵染源和传播途径。
