摘要:
红枣黑斑病是枣果成熟期的主要病害，为了调查该病害在新疆阿拉尔垦区的发病规律，以骏枣和灰枣为试材，应用孢子捕捉技术和多元逐步回归法分析阿拉尔垦区红枣黑斑病的初侵染源、病菌孢子扩散与田间病情的关系以及影响病害流行的主要因素。结果表明：上一年的枣树病残体是红枣黑斑病初侵染源。分生孢子在5月中下旬开始出现，7月中旬至 8月中旬为高峰期，随后进入消退期。分生孢子通常在枣树冠层附近分布较多，全天 24 h 内都可捕到分生孢子，但一般12:00左右捕捉量最多。分生孢子的扩散与温度、降雨量和累积降雨量呈正相关，而且与病害的发生关系较为密切。骏枣抗病性较弱，采用漫灌方式的枣园黑斑病发生较重；9月降雨是影响黑斑病流行程度的重要因子。因此，菌量、品种、灌水、温度和降雨等因素共同影响黑斑病的发生与流行。
Abstract:
Black spot disease of jujube is the main disease in fruit maturity.Incidence characteristics of the disease including primary infection sources,relationships between airborne conidial concentration and disease severity,and main factors affecting factors disease epidemic were investigated by capturing airborne technique and stepwise multiple regression analysis.The results showed that pathogenic fungi present in plant debris were primary infection sources of jujube black spot disease.The conidia initial diffusion was observed in later May and its epidemic was from middle July to middle August.Conidia mainly distributed in jujube canopy.Conidial diffusion peak of daily dynamics was 12:00.Airborne conidial concentrations were positively correlated with temperature,rainfall and disease severity.The identification for the resistance of cultivated jujube varieties to black spot disease showed that Zizyphus jujuba Mill.cv.Huizao was more resistant to Zizyphus jujuba Mill.cv.Junzao.Black spot disease grew worse when using flood irrigation in jujube orchard.Rainfall in September was one of the most important factors,which affect the epidemic scale of black spot disease.In conclusion,the amount of pathogenic fungi,varieties,irrigation,temperature and rainfall co-determine the incidence and epidemic of black spot disease of jujube.
