NPK Fertilization Optimized for Cultivating Chili Peppers for Processing

  • 摘要:   目的  研究氮、磷、钾不同施肥量配比对加工型辣椒产量和品质的影响,明确加工型辣椒高产、优质的氮、磷、钾适宜施用量配比,为加工型辣椒合理施肥提供依据。  方法  采用氮、磷、钾三因素二次饱和D-最优设计,以加工型辣椒品种明椒9号为供试材料,建立氮、磷、钾施肥量编码值与产量、加工品质的效应函数。  结果  氮、磷、钾肥对辣椒产量和加工品质的影响显著,均表现为钾肥>磷肥>氮肥,表明钾是影响辣椒产量和加工品质的重要因素。单因子效应分析表明,当氮、磷、钾肥的最高施用量分别为151.10、59.28、306.78 kg·hm−2时,辣椒产量达到最高;当氮、磷、钾肥的最高施用量分别为148.59、59.34、291.66 kg·hm−2时,辣椒加工品质达到最佳。互作效应中,氮磷、氮钾、磷钾互作对辣椒产量和加工品质影响显著,两者配施对辣椒产量和加工品质的提高具有较强的促进作用。模型寻优表明,辣椒产量超过29000 kg·hm−2,在95%置信区间,氮、磷、钾肥适宜施用量分别为109.24~174.43 、44.40~78.95 、213.85~287.95 kg·hm−2;辣椒品质综合评分在80分以上,在95%置信区间,氮、磷、钾肥适宜施用量分别为63.08~115.23、 42.26~72.50 、211.23~292.23 kg·hm−2  结论  辣椒产量达29000 kg·hm−2、加工品质综合评分达80分以上的施肥方案为氮肥109.24~115.23 kg·hm−2,磷肥44.40~72.50 kg·hm−2,钾肥213.85~287.95 kg·hm−2,适宜的氮、磷、钾肥施用量比例约为1.00~1.05∶0.41~0.6∶1.96~2.64。
