【摘要】用多项式模式模拟预测了2001年玉溪红塔区烤烟赤星病病指的趋势值,并与实测值进行了误差分析;同时已模拟预测了2002年烤烟赤星病病指的发生趋势值,为烤烟生产的综合防治工作服务。更多还原

【Abstract】 The polynomial model simulation was used to predict the year 2001′s tendency values of the disease indexes of fluecured tobacco brown spot in Hongta area, Yuxi and the error analysis was carried out by comparing with the actual values. Also the incidence tendency values of the disease indexes were simulated for the year 2002 and the results could service the comprehensive prevension and control of this disease in tobacco production.更多还原
