Analysis of Tobacco Leaves Quality for Different Sunshine Duration in Honghe, Yunnan Province
By the parallelism investigation of the growth condition of tobacco and weather factors in various elevation heights, the correlation analysis is made. It is shown that in the various growth stages tobacco leaves request different sunshine duration. With quadratic curve, the variation of the sunshine duration with the elevation height is simulated. The most suitable time period and the elevation height for the fine quality of tobacco leaves growth are put forward.
