摘要
立足贵州省三大典型气候区2012年烟草青枯病发生流行的概况和新特点,采用系统调查和普查相结合的方法,阐述了不同气候区青枯病的发生规律,重点分析了三大气候区2012年度气候条件和不同品种对青枯病发生流行的影响。结果表明,烟草青枯病在贵州省天柱、开阳、威宁3个气候区始发时间逐渐延迟,为害程度呈逐渐减弱趋势。气候条件是影响青枯病的主要因素,而温度是引起3个气候区烟草青枯病发生流行早晚及轻重程度不同的关键因子。此外,不同品种在同一气候区的发病情况不同,同一品种在不同气候区的发病情况差异较大。
Based on the occurrence situation and the new characteristics of tobacco bacterial wilt in three typical climatic regions of Guizhou province in 2012, this paper expounded the occurrence regularity of the disease through systemic investigation and general survey, and especially analyzed the effect of climate condition in 2012 and different varieties on tobacco bacterial wilt. The results showed that the beginning period of the disease gradually delayed, and damage degree of the disease weakened gradually in Tianzhu, Kaiyang and Weining county of Guizhou. The main factor influencing the disease was climate condition, while the most important factor, influencing early or late occurence and the degree of the disease among the three climatic regions, was temperature. Moreover, the disease development in the same climatic region of different varieties were different, the disease development in different climatic region of the same varieties were quite different.
