气候变暖对云南烤烟生产影响的初步分析

Influence of Climate Warming to Tobacco Production of Yunnan

通过对云南6个烤烟种植区35a来烤烟大田生长期气温资料的初步分析发现：云南省6个烤烟生产区烤烟大田生长季平均气温呈明显升高趋势,热量条件有较明显的改善;各烟区烤烟成熟—采烤期气候变暖趋势一致性好、增温最突出、增幅最大,增温幅度达到了0.0155-0.0356℃/a,这在一定程度上缓和了云南省烤烟生产过程中烤烟生长中、后期高温不足这一制约云南烤烟品质提高的气候瓶颈问题,对提高云南省烟叶品质有十分重要的促进作用。

The paper analyzes the temperature data of tobacco growth at six planting areas about 35 years in Yunnan. Results show the mean temperature in the season of growth is increasing obviously and the heat condition is improved obviously. During the periods of tobacco maturation and baking, the consistency of the climate warming trend is fine; the elevated temperature and increase is large, which reaches 0. 015 5--0. 035 6 ℃/a. It is an advantageous tendency to relieve the bottleneck problem that the temperature is not high sufficiently at the metaphase and anaphase of tobacco growing, and it also promotes the tobacco quality of Yunnan .
