Analysis about the Climate Variation Trend during Field Growth Period in Xiangnan Strong Flavor Type Tobacco Cultivation Area
摘要
Abstract
The linear fitting method was adopted to analyse the climate variation characteristic of field growth period in Xiangnan tobacco cultivation area with six meteorologic observation data(1981 -2010)from Guiyang and Jianghua tobacco cultivation area,including temperature,average temperature,sunshine hours,and precipitation,etc. Results showed that 1 ) The rising rate of temperature in field growth period was 0. 544℃/10 a and 0. 626℃/10 a in Guiyang and Jianghua tobac-co cultivation area respectively,and the rising rate of sunshine hours was 30. 672 h/10 a and 69. 744 h/10 a respective-ly. There was a rising trend in light and heat factor in Xiangnan area,which is advantageous to advance the stage of trans-planting and extend field growth period. 2)The rising rate of precipitation in field growth period was 23. 524 mm/10 a and 10. 685 mm/10 a respectively and the rising rate of evaporation was 23. 625 mm/10 a and 65. 811 mm/10 a respective-ly. While the declining rate of relative humidity was 1. 299%/10 a and 2. 589%/10 a respectively,indicating that the de-mand of water and humidity in field growth period would be satisfied in the days to come in Xiangnan tobacco cultivation area. It also an important measure to ensure adequate supply of rainfall simultaneously when the field growth period was ex-tended,to optimize structure of Xiangnan tobacco leaves.关键词
