摘要
在大田条件下,研究了不同基因型玉米对间作花生铁营养的影响。结果表明,与单作花生相比,玉米花生间作提高了花生茎、叶和籽仁铁含量,促进了花生单株铁积累量,与郑单958、登海661和甜单21间作的花生籽仁铁含量分别提高了42.77%～48.47%、16.42%～19.9%和53.83%～60.94%,均达到差异显著水平,单株铁积累量分别提高了45.27%～57.83%、7.07%～13.22%和98.47%～160.99%,除与登海661间作花生外,均达到显著水平;不同基因型玉米改善花生铁营养效果表现为:甜单21>郑单958>登海661。
In the field experiment, the effects of maize on Fe nutrition of intercropped peanut were studied. The results showed： Compared with the sole-cropping peanut, maize intercropped peanut improved the Fe concentration of intercropped peanut in stem, leaf and kernel, promoted the peanut Fe absorbing capacity; Fe concentration in seeds of peanut intercropped with ZD958, DH 661 and TD 21 was increased by 42.77%~48. 470/00, 16.42% ~19.9% and 53.83~ ~60.94%, respectively, which a- chieved significant difference level, and Fe accumulation of intercropped peanut was increased by 45.27 - 57.83%,7.07% - 13.22% and 98. 47% - 160.99%, respectively. The capacity of different genotype maize on Fe nutrition improvement of intercropped peanut was： TD21〉ZD958〉DH661.
