辣椒病毒病发病原因分析

Analysis of the Outbreak Reason on the Capsicum annuum Virus Disease

调查研究表明,辣椒病毒病的发生主要与栽培方式、上茬作物、气候条件、品种等关系密切.日光温室和塑料大棚栽培条件下,病害发生轻、发生晚,前茬为茄果类和瓜类的田块发病重,蚜虫发生量大的年份发生重.在病毒病发生初期,及时防治蚜虫,对病毒病有很好的防治效果.

The virus disease in capsicum annuum was studied.It was clear that the occurrence of the disease is closely related to the culture mode,types of crops in previous season,weather conditions, varieties,and so on.Greenhouse could reduce the severity of the disease.Occurrence in plants grown in greenhouse was late and slight.The disease occurred heavily in the fields where the previous season crops are nightshades or melons.And so did the epidemic when aphid prevailed.And,for this reason,to control aphid population in time could lead to preventative result effectively.
