摘　　要：为解决氮磷钾肥配施比例不合理造成北方寒地珍珠红小豆肥料供给不足和产量低等问题,于2021~2022年采用三因素五水平二次正交旋转组合设计,研究氮磷钾肥不同肥料配比对红小豆产量性状的影响,并构建肥料效应函数模型及最佳施肥方案。研究结果表明:不同氮磷钾肥配施处理对珍珠红小豆产量产生显著影响,其中氮肥和磷肥对产量因子影响显著,钾肥对产量因子影响不显著,具体表现为磷肥>氮肥>钾肥;并通过氮磷钾三因子综合效能模型构建,确定红小豆产量大于1 750 kg/hm~2合理优化施肥模式,其中,N施用量76.071~81.203 kg/hm~2,P_(2)O_(5)施用量101.556~105.788 kg/hm~2,K_(2)O施用量63.275~69.242 kg/hm~2;各因素纯量N∶P_(2)O_(5)∶K_(2)O比例值1∶1.32∶0.843。In order to solve the problems of insufficient fertilizer supply and low yield of red adzuki beans in northern cold regions caused by the unreasonable proportion of nitrogen,phosphorus,and potassium fertilizers,a three factor five level quadratic orthogonal rotation combination design was adopted from 2021to 2022 to study the effect of different fertilizer ratios of nitrogen,phosphorus,and potassium fertilizers on the yield characteristics of red adzuki beans,and to construct a fertilizer effect function model and the optimal fertilization plan.The research results indicate that different combinations of nitrogen,phosphorus,and potassium fertilizers have a significant impact on the yield of red adzuki beans.Among them,nitrogen and phosphorus fertilizers have a significant impact on yield factors,while potassium fertilizer has no significant impact on yield factors.The specific manifestation is phosphorus fertilizer>nitrogen fertilizer>potassium fertilizer;And through the construction of a comprehensive efficiency model of nitrogen,phosphorus,and potassium factors,it was determined that the reasonable and optimized fertilization mode for red bean yields greater than 1750 kg·hm~(-2)was determined.Among them,the N application rate was 76.071~81.203 kg·hm~(-2),the P_2O_(5application) rate was 101.556~105.788 kg·hm~(-2),and the K_(2O) application rate was 63.275~69.242 kg·hm~(-2);The ratio of pure N∶P_2O_5∶K_(2O) for each factor is1∶1.32∶0.843.
