以"湘花2008"为试验材料,通过大田试验,探究不同栽培方式下夏播花生Al、Mn、Cu养分吸收特性和分配规律.结果表明:与露地栽培相比,覆膜+遮阳栽培提高花生不同时期叶和根中Al含量、根中Cu含量,但降低叶、果针中Cu含量,降幅分别为1.20%～17.12%、1.25%～24.95%.花针期、结荚期,覆膜+遮阳栽培降低茎、果针、荚果中Mn和Al含量,而结荚之后茎中的Cu含量降低0.35～0.67 mg/kg.覆膜+遮阳处理有利于花生促进对Al、Mn、Cu的吸收、积累,但不同元素在不同生育阶段积累规律存在差异.覆膜+遮阳栽培显著提高苗期植株Al和Cu的积累量(P＜0.05);成熟期显著提高Mn和Cu的积累量,分别提高23.34%、13.29%.随生育进程的递...

Using Xianghua 2008 as the experimental material,the characteristics of nutrient uptake and distribution of Al,Mn and Cu in summer sowing peanut under different cultivation methods were explored through field experiments.Compared with open field cultivation,the film mulching with shading cultivation in-creased the contents of Al and Cu in peanut leaves and roots at different stages,but decreased Cu content in leaves and fruit needles by 1.20%～17.12%and 1.25%～24.95%,respectively.From the pod-pin stage to pod setting stage,the filming and shadi...
