摘　　要：为揭示不同水肥管理下武都花椒幼苗的抗寒性差异,以武都花椒为试验材料,采用土壤水分和施肥量四因素四水平试验设计,土壤田间持水量(FWC)设置为25%、45%、65%、85%,肥料采用氮磷钾配施,施肥水平设置为氮肥(0、90、180、360 kg/hm~2),磷肥(0、50、100、200 kg/hm~2),钾肥(0、90、180、360 kg/hm~2),系统地观测了不同水肥组合下,武都花椒幼苗的抗寒性指标变化,并利用隶属函数法对各水肥处理下武都花椒幼苗的抗寒能力进行了排序。结果表明,H11(N_(180)P_(100)K_(180)+65%FWC)处理下,武都花椒幼苗的抗寒综合值最优,且施肥处理显著高于不施肥处理。说明适宜的土壤水分和施肥量配比能有效提高武都花椒幼苗的抗寒综合值。To explore the effects of different water and fertilizer management on cold resistance evaluation of Zanthoxylum bungeanum Maxim.A pot experiment with four factors and a four-level orthogonal design,Set the soil moisture 25%,45%,65%,and 85%field water capacity FWC,Set the fertilization level nitrogen(N 0,90,180,and 360 kg/hm 2),phosphorous(including P 2O 50,50,100,and 200 kg/hm 2),and potassium(K 2O 0,90,180,and 360 kg/hm 2).Systematically observed the changes in cold resistance indicators of Zanthoxylum bungeanum Maxim wuduseedings under different water and fertilizer combinations,A subordinate function was applied to comprehensively evaluate the impact of different water and fertilizer on the cold resistance of seedlings.The results showed that H11(N 180 P 100 K 180+65%FWC)treatment caused the optimal comprehensive cold resistance value of Zanthoxylum bungeanum Maxim wudu seedings and the fertilization treatment is significantly higher than the non fertilization treatment.The results suggested that appropriate soil moisture and N,P,and K fertilizer application are important for enhancing Zanthoxylum bungeanum Maxim wudu seedings cold resistance comprehensive value.
