摘　　要：研究不同比例的植物生长调节剂对黄灯笼辣椒产量及养分吸收利用的影响,为植物生长调节剂的合理使用提供理论基础。以黄灯笼辣椒为试验对象,采用盆栽试验,施用不同比例的复硝酚钠、α-萘乙酸钠、胺鲜脂(DA-6),测定各处理对辣椒果实产量、氮磷钾养分累积量及利用率的影响。结果表明,在0.30%、0.50%两种添加浓度下,复硝酚钠、DA-6无论是单独使用还是两者等量复配,均能不同程度促进黄灯笼辣椒对氮、磷、钾养分的吸收,较大程度地提高辣椒产量;2种浓度下,均以复硝酚钠+DA-6组合处理产量最优,分别比常规施肥处理高出48.6%和38.1%。而α-萘乙酸钠无论是单独使用还是与其他调节剂复配,对辣椒养分吸收及产量提高均不及复硝酚钠和DA-6处理。复硝酚钠与DA-6等量复配对黄灯笼产量及生物量影响最大,大大提高了化肥利用率。Study the effects of plant growth regulator on the production and nutrient uptake of yellow lantern chili, in order to provide theoretical basis for the optimal use of plant growth regulator.Taking yellow lantern chili as experimental object,planted at the pot, adding different proportion of sodium nitrophenolate, α-NaNAA, amine fresh grease(DA-6) to study the determination of different processing on pepper fruit yield, and the influence of the cumulative amount of N、P、K nutrients and utilization.The results showed that 0.30% and 0.50% sodium nitrophenolate mixed with DA-6 or used alone could promote the Capsicum production, improving N、P、K absorption and acumulation respectively. Both concentrations of sodium nitrophenolate + DA-6 were the best combination to improve the Capsicum production which is higher than conventional fertilization 48.6% and 38.1%. Under the two concentrations, whenα-NaNAA was used separated or mixed, chili nutrient uptake and yield growth rates were lower than the sodium nitrophenolate and DA-6.Sodium nitrophenolate + DA-6 was the best combination to improve the amount of fruit yielding, biomass, and the utilization of fertilizers.
