Abstract

Abstract: With zinc（Zn） efficiency（Zhengdan 958，ZD958）and insensitivity types（Longping 638，LP638）as materials，the effects of nitrogen（N）rates［225 kg/ha（HN），180 kg/ha（MN）and 90 kg/ha（LN）］and foliar Zn［no Zn（Zn0），spraying Zn of 1∶1 at jointing stage and flare opening stage（Zn1）］on the yield and content，accumulation and distribution of mineral elements in grain at different positions of maize ear，so as to provide scientific basis for the N and Zn fertilization in summer maize production.The result indicated that in general，the kernel number，1 000‐grain weight，yield and mineral element accumulation showed upper grain<middle grain<basal grain.MN had the highest upper grain yield，and HN had the highest middle and basal grain yield.Foliar Zn improved the yield of upper，basal and whole grain；Compared with LP638，the upper and basal grain yields of ZD958 were higher.Overall，MNZn1ZD958 treatment had high upper，basal and whole grain yield，Zn content in whole grain，and potassium（K）and manganese（Mn）accumulation in upper grain. HNZn1ZD958 treatment had higher yield，N and Mn contents in whole grain，copper（Cu）and Zn contents in upper grain and Cu content in middle grain，and increased the proportions of Mn and Zn in upper grain and Cu in middle grain.There was significantly positive correlation between whole grain yield and basal grain yield；N content in whole grain was significantly positively correlated with middle grain yield，and significantly negatively correlated with Mn and Zn contents.By comprehensive consideration，spraying Zn of 1∶1 at jointing stage and flare opening stage can improve yield under 180—225 kg/ha N condition；Spraying Zn of 1∶1 at jointing stage and flare opening stage can promote N，Zn and Mn accumulation under 180 kg/ha N condition；Spraying Zn of 1∶1 at jointing stage and flare opening stage is conducive to the transport of Cu，Mn and Zn to basal grain under 90 kg/ha N condition；Spraying Zn of 1∶1 at jointing stage and flare opening stage is conducive to the transport of N，Mn and Zn to upper grain under 225 kg/ha N condition.

摘要： 以锌高效玉米品种（郑单958）和锌不敏感品种（隆平638）为研究对象，研究施氮量［225 kg/hm²（HN）、180 kg/hm²（MN）、90 kg/hm²（LN）］和喷锌［不喷施（Zn0）、拔节期和大口期1∶1 喷锌4.5 kg/hm²（Zn1）］对玉米果穗不同粒位籽粒产量和矿质元素含量、累积及分配的影响，为氮锌配施在大田玉米生产中的合理利用提供依据。结果表明，不同粒位的籽粒数、千粒质量和产量以及各矿质元素累积量总体上均表现为上部<中部<下部；上部粒位的产量以MN处理最高，而中、下部则均以HN处理最高；喷锌提高了果穗和上部、下部粒位的籽粒产量，郑单958上部和下部粒位籽粒产量均高于隆平638。总体上，MNZn1处理郑单958果穗和上部、下部粒位的籽粒产量均较高，且果穗籽粒锌含量、上部粒位籽粒中钾和锰累积量也表现最高；HNZn1处理郑单958果穗籽粒产量、氮和锰含量及上部粒位籽粒铜和锌含量、中部粒位籽粒铜含量较高，同时也能提高上部粒位籽粒中锰和锌占比、中部粒位籽粒铜占比。果穗籽粒产量与下部粒位籽粒产量呈显著正相关；果穗籽粒中氮含量与中部粒位籽粒产量呈极显著正相关，但与下部粒位籽粒中锰和锌含量呈显著负相关。总体来看，施氮量180~225 kg/hm²条件下拔节期和大口期1∶1喷锌4.5 kg/hm²能够提高锌高效玉米品种籽粒产量，施氮量180 kg/hm²条件下喷锌促进氮、锌、锰等元素积累，施氮量90 kg/hm²条件下喷锌有利于铜、锰和锌向下部粒位转运，施氮量225 kg/hm²条件下喷锌则有利于氮、锰和锌向上部粒位转运。
