| 摘 要： | 为有效防治辣椒疫霉病，对辣椒疫霉病田土壤进行了病菌分离、菌株配对培养、越冬存活形式等研究。结果表明：病田土壤中的疫霉菌数量有明显的季节性变化。以5-8月最多，冬季和初春最少；湖南长沙地区疫霉菌的配对型有A2和A1A2两种类型，多以卵孢子形态在土壤中越冬；病田土壤和植物病残体是辣椒疫霉病最主要的初侵染源。 |

| Abstract: | To provide a basis for the prevention and cure of Phytophthora capsici pathogen,pathogen isolation,quantitative detection, matching culture and over-wintering survival studies were carried out with soil infected with Phytophthora capsici.The results show that the number of Phytophthora capsici pathogens keeps the largest number in May,June,July and August,and the smallest in winter and early spring.Two matching types (A 2,A 1A 2) of Phytophthora capsici are identified in Changsha region of Hunan, and they often overwinter in the soil as oospore.Infected soil and remains of infected plants are the main primary infection sources of capsicum pathogen. |
