Jemporal epidemic dynamics and climatic factors of transmission of tobacco bacterial wilt in Qingjiang river basin
摘要
Abstract
In order to better forecast,prevent and control tobacco bacterial wilt in Qingjiang river basin,the occurrence,jemporal epidemic dynamics and climatic factors were determined,and the best control periods were put forwarded by using system investigation and statistical analysis.(1) The cubic equation model could well reflect the jemporal epidemic dynamics of tobacco bacterial wilt,thus helping predict occurrence of the disease.(2) Tobacco bacterial wilt in the area occurred relatively smooth at the beginning,spreading rapidly and growing sharply in late stages.The occurrence of the disease could be classified into three periods:starting period (45～67 d after transplanting),quickly spread period (67～97 d after transplanting) and entirely outbreak period (97 d after transplanting to the end of harvest).(3) The prevention period and the critical periods using medicamentosus method for tobacco bacterial wilt were put forward.The first was 45d before transplanting with mean temperature under 18.82 ℃;and the second was 67d before transplanting with mean temperature under 22.00 ℃.The control period for tobacco bacterial wilt with the occurrence stage and temperature into consideration would be more advantageous to effective prevention and control of tobacco bacterial wilt.关键词
