鄂西北2023年秋季低温连阴雨特征及其对烤烟质量的影响
Characteristics of Low Temperature and Continuous Rainy Weather in Autumn of 2023 in Northwest Hubei and Its Impact on Quality of Tobacco
摘要
Abstract
The frequent occurrence of low temperature and continuous rain in autumn in northwest Hubei tobacco area posed a potential threat to the yield and quality of flue-cured tobacco.This article statistically analyzed the regional differences in the impact of low temperature and continuous rainy weather on the quality of tobacco in Shiyan and Xiangyang in autumn 2023.Based on the meteorological data of 6 national meteorological stations and 138 flue-cured tobacco samples,the influence of the event was analyzed by statistical analysis and ArcGIS interpolation.The results showed that from September 18 to October 7,2023,a severe regional continuous rain occurred in the tobacco growing areas of northwest Hubei.During this period,the sunshine hours were significantly reduced(65-82 h)compared with the same period of normal years,and the number of days with daily average temperature≤18℃reached 8-17 days.The single leaf weight of B2F grade flue-cured tobacco in Xiangyang tobacco area decreased significantly(13.3%),the stem content of C3F grade increased(9.3%),and the sensory quality decreased.Shiyan tobacco area was less affected,mainly due to the early transplanting period of about 20 days.The low temperature and continuous rain caused significant damage to the quality of flue-cured tobacco,and the influence degree of Xiangyang tobacco area was significantly higher than that of Shiyan tobacco area.It is suggested that the transplanting period of Xiangyang tobacco area should be 20 days in advance to effectively reduce the negative impact of continuous rain on the appearance and sensory quality of flue-cured tobacco.It is expected that the decrease of single leaf weight of B2F grade can be reduced by 5%.关键词
