摘　　要：为提高蔬菜品质,减少过量的化肥投入,在土壤速效磷含量较高的情况下,通过配合施用有机肥,研究追施磷肥对甜椒产量、品质和土壤速效磷的影响。设4个处理,分别为处理1(T1):底肥不施用有机肥,不追施磷肥;处理2(T2):底肥不施用有机肥,追施磷肥纯量5 kg·667 m^-2;处理3(T3):底肥施用有机肥2000 kg·667 m^-2,不追施磷肥;处理4(T4):底肥施用有机肥2000 kg·667 m^-2,追施磷肥纯量5 kg·667 m^-2。结果表明,施用有机肥后,不追施磷肥情况下对甜椒的产量和品质没有显著影响。其中,处理4甜椒产量最高,为2430.75 kg·667 m^-2,处理1产量最低,为2019.80 kg·667 m^-2。处理3甜椒果实品质优于处理1和处理2,与处理4之间无显著差异,说明施用有机肥后,不追施磷肥对甜椒品质没有明显影响。不施用磷肥能够减少有效磷在土壤中的累积,处理4施肥后土壤有效磷含量最高,为247 mg·kg^-1,与其他处理相比分别增加40.34%、26.02%、13.30%。In order to improve vegetable quality and reduce excessive chemical fertilizer input,this study was conducted to evaluate the effects of phosphorus fertilizer topdressing on sweet pepper yield,quality and soil available phosphorus under high phosphorus content soil.A field experiment was carried out,four treatments were set up in this study,T1:base fertilizer was not applied organic fertilizer,no topdressing phosphorus fertilizer;T2:base fertilizer was not applied organic fertilizer,topdressing phosphorus fertilizer purity was 5 kg per 667 m^2;T3:base fertilizer was applied organic fertilizer 2000 kg per 667 m^2,no topdressing phosphorus fertilizer;T4:base fertilizer was applied organic fertilizer 2000 kg per 667 m^2,topdressing phosphate fertilizer was 5 kg per 667 m2.The results showed that the yield and quality of sweet pepper were not affected by the application of organic fertilizer without phosphate fertilizer.The yield of sweet pepper in T4 was the highest(2430.75 kg per 667 m^2),and that of T1 was the lowest(2019.80 kg per 667 m^2).The fruit quality of treatment 3 was found no significant difference with treatment 4,which indicated that no application of P fertilizer had no significant effect on the quality of sweet pepper.No application of phosphorus fertilizer could reduce the accumulation of available phosphorus in soil.The highest content of available phosphorus was 247 mg·kg^-1 in T4,which increased by 40.34%,26.02%and 13.30%respectively compared with other treatments.
