| 摘 要： | 白术黑斑病在白术全生育期均可发病，发生严重地块，重病株率可达50％～70％。通过对黑斑病系统调查研究，明确了该病的病原为细交链孢Alternaria alternata(Fr) Keissler，病害发生与植株长势、土壤肥力、气象条件关系密切。凡植株长势弱、土壤肥力不足、连续降雨或有较大降雨，均有利于病害发生。

| Abstract: | The disease of black spot can occur over the growth duration of the largehead atractylodesrhizome.The percentage of diseased plants whose leaves and stalks became black and died reached50%~70% in the severely diseased fields.Systematic surveys on this disease indicated that:(1) thepathogen causing this disease was alternaria (Fr);(2) the occurrence of this disease was closelycorrelated with growth vigor of the plant,the soil fertility and weather conditions.Bad growth vigor ofthe plant,barren soil and heavy rainfall enhances the occurrence of this disease. |
