【摘要】 分析了气象条件对闽西北烟草普通花叶病(TMV)发生发展的影响。分析得出:温度、湿度、降水及日照等气象因子对TMV发生发展均有明显的影响,但影响程度和关键时段不尽相同,影响最大的是湿度和降水,温度次之,日照最小;TMV始发时温度起主要作用,而流行时起主要作用的是湿度和降水。建立了闽西北地区TMV发生程度的中期预测模式,并提出了防治措施。更多还原

【Abstract】 The influence of meteorological conditions on the occurrence and development of tobacco mosaic virus(TMV) in Northeast Fujian is analyzed.The results suggest that some meteorological factors such as temperature,moisture,rainfall and sunshine have remarkable effects on TMV occurrence and development;but the degree of the effects and the key influencing periods are different.The most effective factors are moisture and rainfall,then temperature,and the least is sunshine.Temperature plays a major role,and minimum temperature has the most important role at the beginning of TMV attack;the moisture and the rainfall play a key role and sunshine has an obvious negative role during the prevailing period.A mid-term forecast model of TMV occurrence is developed and some prevention suggestions are presented.更多还原
