采用大田试验。在基肥中用部分氯化钾替代硫酸钾，追肥仍然使用原专用追肥。研究在不同氯浓度处理下烤烟三个重要的生理时期（团棵期、现蕾期、成熟期）对氯的吸收积累特性，以及对氮、磷、钾吸收的影响。结果表明：对烤烟烟叶各部位氯含量的测定分析得出：烟叶氯的积累量为下部叶＞中部叶＞上部叶。团棵期烤烟氯的积累量随氯肥替代的增加出现曲折下降趋势，20%氯替代时达到最大积累量0.36%，现蕾期和成熟期各部烟叶在50%氯替代下，烟叶氯含量分别超过0.2%和0.5%。上部叶的烟叶含氮量随氯替代的增加而降低，中、下部叶含氮量无明显变化；各处理下，下部烟叶的钾含量均较上、中部烟叶高，无氯替代、20%氯替代和30%氯替代处理下差异较为明显，而上部烟叶与中部烟叶的含钾量无明显差异。施氯处理与不施氯处理对烟株磷含量的积累，无太大影响。
採用大田試驗。在基肥中用部分氯化鉀替代硫痠鉀，追肥仍然使用原專用追肥。研究在不同氯濃度處理下烤煙三箇重要的生理時期（糰棵期、現蕾期、成熟期）對氯的吸收積纍特性，以及對氮、燐、鉀吸收的影響。結果錶明：對烤煙煙葉各部位氯含量的測定分析得齣：煙葉氯的積纍量為下部葉＞中部葉＞上部葉。糰棵期烤煙氯的積纍量隨氯肥替代的增加齣現麯摺下降趨勢，20%氯替代時達到最大積纍量0.36%，現蕾期和成熟期各部煙葉在50%氯替代下，煙葉氯含量分彆超過0.2%和0.5%。上部葉的煙葉含氮量隨氯替代的增加而降低，中、下部葉含氮量無明顯變化；各處理下，下部煙葉的鉀含量均較上、中部煙葉高，無氯替代、20%氯替代和30%氯替代處理下差異較為明顯，而上部煙葉與中部煙葉的含鉀量無明顯差異。施氯處理與不施氯處理對煙株燐含量的積纍，無太大影響。

Using Field experiment. With potassium chloride in the basal topdressing potassium sulfate substitution, still using the original special fertilizer.The absorption and accumulation of chlorine in three physiological stages (stage, budding stage and maturity stage) of flue-cured tobacco were studied under different chlorine concentrations,and the influence of nitrogen, phosphorus and potassium absorption. The results shows that:The contents of chlorine in the tobacco leaves were analyzed,the accumulation of chlorine in the leaves was lower than that in the middle leaves.The accumulation of chlorine in the stage of the tobacco group increased with the increase of chlorine fertilizer, and the trend of the increase of the chlorine fertilizer was 20%. The maximum amount of the chlorine was 0.36% when the chlorine was replaced.At the present stage and in the mature stage, the chlorine content of the tobacco leaves was more than 0.2% and 0.5% respectively in the 50% chlorine substitution.The content of nitrogen in the upper leaves decreased with the chlorine substitution, and the nitrogen content in the middle and lower leaves had no obvious change.Each treatment, the potassium content in lower leaves are more than, middle leaves high, no chlorine substitution, 20% chlorine substitution and 30% chlorine substitution treatment differences are obvious, and the potassium content of upper leaves and middle leaves no obvious difference.The accumulation of phosphorus in the tobacco plant was not affected by chlorine treatment and chlorine treatment..
