摘要:: 以‘艳椒425’辣椒为试材，采用盆栽试验，设置2个CO2浓度（自然CO2（400±30）μmol·mol-1、CO2加富（800±30）μmol·mol-1）及3个施磷水平(P0 0 mg·kg-1、P50 50 mg·kg-1、P250 250 mg·kg-1），研究了CO2加富与磷配施对辣椒根系形态及磷含量的影响，以期为适应环境变化下辣椒种植及合理施肥提供参考依据。结果表明：1）CO2加富与磷配施显著促进辣椒根系生长及根冠比增加；2）CO2加富与施磷及二者配施均增加叶绿素含量，显著降低ACP活性；3）施磷显著增加辣椒根系及总磷含量，但过量施磷对磷含量无显著促进作用，而CO2加富则显著降低辣椒根系及总磷含量；4）CO2加富与施磷及二者配施显著增加辣椒根系磷吸收转运比例，CO2加富显著减少叶片磷吸收转运比例，而施磷是显著减少茎的磷吸收转运比例。综上所述，在实际生产过程中，要适量合理施肥，避免造成肥料浪费及土壤富营养化。

Abstract:: Taking ‘Yanjiao 425’ bulbs as experimental materials and the pot control experiment was carried out，two CO2 concentrations natural (CO2 concentration (400±30)μmol·mol-1，CO2 enrichment (800±30)μmol·mol-1) and three phosphorus levels(P0 0 mg·kg-1;P50 50 mg·kg-1;P250 250 mg·kg-1) were set to study the effects of CO2 enrichment and phosphorus application on the root morphology and phosphorus content of pepper，in order to provide reference for pepper planting and reasonable fertilization under environmental changes.The results showed that,1) CO2 enrichment and phosphorus combined application significantly promoted the root growth and root-shoot ratio of pepper.2) CO2 enrichment and phosphorus application and the combination of both increased chlorophyll content and significantly reduced ACP activity.3) Phosphorus application significantly increased the root and total phosphorus content of pepper，but excessive phosphorus application had no significant effect on phosphorus content，while CO2 enrichment significantly reduced the root and total phosphorus content of pepper.4) CO2 enrichment and phosphorus application and the combination of the two significantly increased the proportion of phosphorus uptake and transport in pepper roots，and CO2 enrichment significantly reduced the proportion of phosphorus absorption and transport in leaves，while phosphorus application significantly reduced the proportion of phosphorus absorption and transport in stems.To sum up，in the actual production process，it is necessary to apply fertilizer appropriately and reasonably to avoid fertilizer waste and soil eutrophication.
