摘　　要：通过盆栽和大田试验,研究了氮镉交互作用下不同改良剂(有机肥、双氰胺和石灰)对辣椒品质的影响。结果表明:在试验范围内,有机肥处理与对照相比均显著提高了辣椒中干物质和叶绿素的含量;3种改良剂的施用均降低了辣椒中Vc、可溶性糖、可溶性蛋白以及镉与硝酸盐的含量,对Vc的影响是对照】石灰】有机肥】双氰胺,但是盆栽中石灰、有机肥与对照间差异不显著;对可溶性蛋白来说:对照】双氰胺】石灰】有机肥,但盆栽中双氰胺、石灰处理间差异不显著,大田中3种改良剂处理间差异均不显著;对于可溶性糖来说:对照】有机肥】双氰胺】石灰,但在大田中双氰胺、有机肥处理间差异不显著;有机肥、石灰、双氰胺处理与对照相比,盆栽和大田中辣椒镉的累积量分别降低5.37%、30.99%、35.95%和52.75%、84.62%、86.26%;双氰胺、有机肥、石灰处理与对照相比,盆栽和大田中硝酸盐的累积量分别降低21.78%、31.37%、35.90%和12.67%、25.51%、34,68%。The effects of three soil amendment(organic fertilizer,dicyandiamide and lime) on quality of pepper in interaction of nitrogen nutrition and cadmium contamination soil were studied through pot and field experiments.The results showed that the organic fertilizer could significantly raise the contents of the dry matter and chlorophyll in pepper Compared with CK,and the three modifiers could all decrease the contents of Vc,soluble sugar,soluble protein,Cd and nitrate.The influence order on the Vc was CK>lime>organic fertilizer>dicyandiamide,but in the pot experiment,there was not significant difference among the lime,organic fertilizer and CK.The influence order on the soluble protein was CK>dicyandiamide>lime>organic fertilizer,and in the pot experiment the difference between the dicyandiamide and lime was not significant and in the field experiment the three improving treatments were not significant difference.The influence order on the soluble sugar was CK>organic fertilizers>dicyandiamide>lime,and in the field experiment the difference between the dicyandiamide and lime was not significant. Compared with CK,organic fertilizer,lime and dicyandiamide could make the contents of Cd in the pepper decrease 5.37%,30.99%and 35.95%(in the pot experiment ),and 52.75%,84.62%and 86.26%(in the field experiment),respectively;dicyandiamide,organic fertilizer and lime could make the contents of nitrate in the pepper decrease 21.78%,31.37%and 35.90%(in the pot experiment),and 12.67%,25.51%and 34.68%(in the field experiment),respectively.
