摘  要:
为优化烤烟节水灌溉模式,采用避雨控水试验研究了9种节水灌溉模式对烤烟干物质、养分积累与分配、产量及水分生产效率的影响。结果表明,干物质在叶部的积累比在其他器官中对水分调控更为敏感,处理3(50%θF-80%θF-60%θF)较其他处理更有利于提高烤烟叶片生产能力;烤烟氮、磷、钾元素积累受水分调控的影响程度由大到小依次为氮、磷、钾,处理6(60%θF-80%θF-70%θF)对氮、磷、钾元素吸收相对均衡;9个节水灌溉模式中,处理3节水增产效果明显。

摘  要:
To optimize the mode of water-saving irrigation for flue-cured tobacco,a rain-proof experiment was conducted to investigate the effects of 9 water-saving irrigation modes on accumulation and distribution of dry matter and nutrient、yield and water productivity of flue-cured tobacco.The results showed that the dry matter accumulation of leaf was more sensitive to water control than that of other organs,treatment 3(the mode of "50%θF-80%θF-60%θF") could improve the producing ability of leaf better than other treatments;the influence of water control to the accumulation of N,P and K was N>P>K;compared with those of other treatments,N,P and K of treatment 6(the mode of "60%θF-80%θF-70%θF") was balance;treatment 3 was more effective to increase yield and water saving than other treatments.
