摘要
[目的]分析浏阳烟区烤烟适种的气候资源条件。[方法]利用浏阳气象观测站1981～2010年的气象资料,结合浏阳烟区生产的实际情况,总结了浏阳烟区的气候资源利弊并提出应对措施。[结果]浏阳烟区日平均气温>20℃的天数约140～150 d,>10℃积温为5 123～5 447℃.d,光照充足,雨量丰沛,满足优质烤烟生长发育所需要的气候环境。[结论]烤烟全生育期除苗床期处在低温阴雨寡照的不良生长环境中,4～7月气候都适宜烤烟生长,但最适宜的气候是4月下旬～7月上旬。
[Objective] To analyze suitable climate conditions for growing tobacco in Liuyang.[Method] By using meteorological data in observation station in Liuyang during 1981-2010,combining with actual production situation,the advantages and disadvantages of climate resource were summarized,corresponding countermeasures were put forward.[Result] The number of days with an average daily temperature above 20 ℃ is about 140-150 d,the accumulated temperature above 10 ℃ is 5 123-5 447 ℃ in Liuyang tobacco-growing areas where there is sufficient sunshine and plentiful rainfall satisfying the climate requirements necessary for the growth and development of quality flue-cured tobacco.[Conclusion] The seedbed period is in the adverse environment for growth which has low temperature,more overcastting and rainy days and insufficient sunshine,but apart from that period,the climate of April to July is suitable for flue-cured tobacco growth in the rest of the whole growth and development period,and the most appropriate climate in late April to early July.
