龙岩市烤烟最佳移栽期研究

摘要

The damage of low temperature on tobacco seedlings that just transplanted to field was analyzed in Longyan city,and then the freeze injury grades of tobacco seedling at transplant stage were determined.Meanwhile,the distribution characteristics of temperature from February to March in 1960-2005 were studied to determine the best transplant period at different areas.The results showed that the best transplanting period of flue-cured tobacco from south to north of Longyan City were before the middle of February,in late February,in early March and in late March in turn.%分析低温条件对刚移栽到大田烟苗的危害情况,确定龙岩市烤烟移栽期烟苗的冻害等级,同时利用1960～2005年2～3月龙岩的温度分布特征,确定各地烤烟最佳移栽期,结果表明：龙岩烤烟最佳移栽期由南向北依次为2月中旬以前、2月中下旬、3月上旬、3月中下旬。
