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.
