广西凤山烟区气候特征与烤烟种植适应性评价

Assessment on climate characteristics and flue-cured tobacco adaptability in Fengshan tobacco planting area of Guangxi

【目的】研究广西凤山县烤烟种植气候适应性,为凤山烟区烤烟种植季节安排提供理论依据。【方法】通过分析凤山烟区温度、降雨、光照等关键气候指标及其分布规律,研究不同移栽期(气温稳定通过13、15、18℃的日期)情况下关键气候指标与优质烟生长需求的吻合情况。【结果】凤山烟区温度、光照、降雨等条件均能满足优质烟叶生长需求,尤其在气温稳定通过18℃时(4月上旬)进行移栽,各项气候资源条件与优质烟生长需求高度吻合,十分有利于优质烟叶生长和质量的形成。【结论】凤山县具备生产优质烟叶的气候条件,适宜的栽期安排应在4月上旬左右。

[Objective ]The aim of this experiment was to study flue-cured tobacco adaptability to climate in Fengshan tobacco planting area in Guangxi and provide theoretical references for planting tobacco in appropriate season in Fengshan. [ Method ]Based on the analysis of key climate indexes such as temperature, precipitation, light and their distribution rule, coincidence degree of key climate indexes and demand for high quality tobacco growth was studied under different transplanting stages when temperature steadily passed 13, 15 and 18℃. [Result]The conditions of temperature, light, precipitation, and relative humidity in Fengshan tobacco planting area could all meet the demand for growth of high quality tobacco; particularly when transplanted at 18℃ in early April, key climate indexes coincided highly with the demand for growth of high quality tobacco, which was tremendously beneficial for the growth of elite tobacco leaves. [Conclusion]Climate of Fengshan County was suitable for growing tobacco, and the appropriate transplanting period was at early April.
