在防雨棚人工控水条件下,采用盆栽试验模拟花生不同生育时期干旱胁迫,调查产量和农艺性状等抗旱性指标,利用抗旱系数法和多性状隶属函数方法分析、鉴定9个商花系列花生品种的抗旱性。结果表明,在苗期、花针期及全生育期干旱条件下,花生产量的下降幅度分别为9.91%~46.86%、16.80%~86.62%和63.99%~97.29%。干旱时期不同,通过抗旱系数法和抗旱性综合评价值(D)筛选出的抗旱品种存在差异。综合不同生育时期干旱,利用平均抗旱系数和平均综合D值筛选出强抗旱品种为商花21号、商花33号和商花43号。不同生育时期干旱条件下,去根生物量、结果枝数和单株果质量的隶属函数值均与抗旱系数呈显著或极显著相关关系,可作为鉴定花生品种抗旱性的指标。研究结果可为区域推广商花系列抗旱新品种及筛选优异抗旱种质资源提供理论参考。

As an effective strategy to improve the properties of electrocatalysts,magnetic field-assisted electrocatalytic water splitting has attracted increasing attention ***,the corresponding enhancements mostly depend on the exertion of an external magnetic field during electrochemical reactions,which results in a high cost of industrial production,and makes the magnetic field manipulation of electrocatalysis become a challenging *** this work,instead of the external magnetic field,a bias magnetic field is self-supplied by the remanence state of a ferromagnetic electrocatalyst of *** to the assistance of this bias magnetic field,the FePt film in the remanence state shows the overpotential of 229 mV during hydrogen evolution reaction,which is much lower than that in its demagnetization state(283 mV).Our findings demonstrate that the remanence in ferromagnetic electrocatalysts can improve the catalytic performance,which is attributed to the decrease in domain walls.
