    Abstract:

    Based on the data of flue-cured tobacco yield from 1991 to 2017 in the nine tobacco producing counties of Lian ̄ gshan prefecture and the meteorological data of national meteorological observation station in the same periodꎬ the trend yield and meteorological yield of flue-cured tobacco were separated through the interannual trend processing. The dynamic effects of meteorological factors such as sunshineꎬ air temperature and precipitation on the yield of flue-cured tobacco were studied by integral regression methodꎬ and the comprehensive simulation model of meteorological yield of flue-cured tobac ̄ co was established. The results show that: (1) Air temperatureꎬ precipitation and sunshine can significantly affect the yield of flue-cured tobacco in Liangshan Prefecture. (2) The key meteorological factors affecting the yield of flue-cured tobacco are different among countiesꎬ while the influence of air temperature is more significant. (3) The key meteorologi ̄ cal factors in Ningnan County and Huidong County are the same and their dynamic effects are similar. (4) The accuracy of the model is high with the deviation of only 2.4%-4.6%.
