磷素营养供应不足或过剩都会影响烤烟正常生长。本试验采用盆栽试验研究不同有效磷水平的植烟土壤对烤烟生长及干物质积累的影响。结果表明，在土壤有效磷含量为13.29 mg · kg -1、土壤磷最大吸附量 Xm为67.3 mg · kg -1的潮砂田上，施磷1.35 g ·盆-1（P4）的烤烟农艺性状处于较高水平，干物质积累与P5处理差异不显著，可满足烤烟正常生长需求。在土壤有效磷为28.66 mg · kg -1、土壤磷最大吸附量 Xm为168.2 mg · kg -1的黄泥田，施磷2.00 g ·盆-1（P5）处理的烤烟农艺性状水平最好，与其他处理差异显著，且全株干物质含量最大（79.03 g ·盆-1），与P4处理差异极显著，说明 P5处理可满足烤烟正常生长需求。在土壤有效磷为54.50 mg · kg -1、土壤磷最大吸附量 Xm为104.0 mg · kg -1的灰泥田上，施磷1.35 g ·盆-1（P4）处理的烤烟农艺性状水平最好，与其他处理差异显著，且全株干物质积累最大（95.04 g ·盆-1），说明P4处理能满足烤烟生长。在同一施磷水平条件下，烤烟的农艺性状及干物质累积量大小为：灰泥田＞黄泥田＞潮砂田，说明植烟土壤的有效磷水平及磷最大吸附量不同对烤烟生长具有重要影响。

The regular growth of flue-cured tobacco is affected by phosphorus supply . The pot experiment was conducted to study effects of phosphorus rate in tobacco-planting soil with different available phosphorus levels on the growth and dry matter accumulation of flue-cured tobacco . The results showed that , in moist sandy land (available phosphorus 13.29 mg · kg -1 , soil phosphorus adsorption maximum 67.3 mg · kg -1 ) , phosphorus application was 1.35 g · pot-1 (P4) which the agronomic traits of flue-cured tobacco exhibited higher levels ,the dry matter accumulation of flue-cured tobacco was not significant with P5 treatment and could meet the demand of the regular growth of the flue-cured tobacco . In yellow clayey soil (available phosphorus 28.66 mg · kg -1 , phosphorus adsorption maximum 168.2 mg · kg -1 ) , the agronomic traits of flue-cured tobacco which applied 2.00 g · pot-1 (P5 ) phosphorus was at the best level significantly higher than other treatments . The dry matter accumulation of flue-cured tobacco could reach the maximum value 79.03 g · pot-1 significantly higher than P4 treatment ,which could meet the demand of the regular growth of the flue-cured tobacco .In paddy field (available phosphorus 54.50 mg · kg -1 , phosphorus adsorption maximum 104.0 mg · kg -1 ) , the agronomic traits of flue-cured tobacco which applied 1.35 g · pot-1 (P4) phosphorus was at best level significantly higher than others .The dry matter accumulation of flue-cured tobacco could reach the maximum value 95.04 g · pot-1 , which could meet the demand of the regular growth of the flue-cured tobacco , with the same phosphorus applied , the agronomic traits and dry matter accumulation of flue-cured tobacco were paddy field> yellow clayey soil> moist sandy land . Which showed that phosphorus fertilizer rate in tobacco-planting soil with different available phosphorus levels was significantly related to the growth of flue-cured tobacco .
