In 1988, the planting area of flue-cured tobacco in our county was 28,957 mu, with a total yield of 20,578 mu and a total output of 45,000 dwelling. The yield per unit area dropped by 20% over the previous year and the grade by 8.53%. The author through the investigation and analysis, that the weather this year affect the yield of flue-cured tobacco, the main reason for the decline in quality. Now the impact of climate factors on the production of flue-cured tobacco are analyzed as follows. First, the weather on the growth of flue-cured tobacco Flue-cured tobacco in my county transplanting period is generally in March, mid. The climate in March this year is characterized by: the average daily temperature of 9.6 ℃, 4.5 ℃ lower than the same period last year; effective accumulated temperature of 216.1 ℃, 127.5 ℃ lower than last year; sunshine hours 53.9 hours,
