Abstract

According to the survey data of the key growth period of tobacco in Fujian and the high temperature data of 28 meteorological observation sites in 1971–2017, the high temperature conditions were analyzed from days when the daily maximum temperature of flue-cured tobacco from June to July was ≥30 °C. Intensity, the total duration of high temperature process and other indicators to start with the use of GIS software of production of different spatial distribution maps, the local high-temperature hazards were analyzed. The results showed that during the mature period of Fujian flue-cured tobacco, both the high temperature value and the high temperature days increased with the passage of time, which was not conducive to the mature harvest of flue-cured tobacco. The spatial distribution of the high temperature of mature flue-cured tobacco in Fujian has obvious regional differences. The superposition effects of high temperature and high temperature days above 35 °C in the counties and cities in the eastern regions such as Nanping and Sanming are more detrimental to the maturity and harvest of flue-cured tobacco.
