摘要

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。

Abstract: Objective NPK fertilization to maximize the yield and quality of chili peppers for processing was formulated. 【Method】 An experiment of quadratic saturation D-optimal design with three factors of nitrogen, phosphorus, and potassium was applied to optimize the formulation targeted to maximize the yield and quality of Mingjiao 9 chili peppers for further processing. Result Significant effects on chili pepper yield and processing quality were found to be K＞P＞N. The optimal amount of N, P₂O₅, K₂O was 151.10, 59.28, 306.78 kg·hm⁻² to reach the greatest yield, and 148.59, 59.34, 291.66 kg·hm⁻² to achieve the most desirable quality. The combinations of N and P, N and K, and P and K also exerted significant enhancing effects on the chili pepper yield and quality. The optimized fertilizations with a predicted yield exceeding 29,000 kg·hm⁻² at 95% confidence level called for the application N, P₂O₅, and K₂O at 109.24–174.43 kg·hm⁻², 44.40–78.95 kg·hm⁻², and 213.85–287.95 kg·hm⁻², respectively, while for a score above 80 on overall chili pepper quality, the application of 63.08–115.23 kg·hm⁻², 42.26–72.50 kg·hm⁻², and 211.23–292.23 kg·hm⁻², respectively, were determined. Conclusion Experimentally optimized NPK fertilizations for chili pepper cultivation to provide a yield of 29000 kg·hm⁻² and a quality score of 80 or higher were formulated. To accomplish the goal on yield as well as quality, the formulation would include the ranges of 109.24–115.23 kg·hm⁻² on N, 44.40–72.50 kg·hm⁻² on P₂O₅, and 213.85–287.95 kg·hm⁻² on K₂O with a N∶P₂O₅∶K₂O ratio of 1–1.05∶0.41–0.6∶1.96–2.64.
