红河州中低海拔日照时数对烟叶品质的影响

Analysis of Tobacco Leaves Quality for Different Sunshine Duration in Honghe, Yunnan Province

通过对不同海拔高度烤烟生长状况与气象因子的平行调查,采用相关分析,揭示了烤烟大田生长期与日照时数的相关关系,表明烤烟不同生长时段要求日照时数不同。用二次曲线模拟了日照时数随海拔高度的变化情况,指出生产优质烟的适宜海拔界限和品质形成最佳时段,为优质烟生产提供科学依据。

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.
