灭菌土壤玉米-花生混作对花生铁营养的影响研究

Effects of mixed cropping of maize and peanut on the Fe nutrition of peanut in sterilized soil

盆栽试验研究灭菌土壤玉米 花生混作对花生植株Fe营养与根际土壤有效铁的影响结果表明 ,玉米 花生混作可显著提高花生新叶叶绿素及活性铁含量 ,下针初期可增加花生地上部全Fe含量和根际土壤活性铁含量 ,混作在改善花生Fe营养过程中始终起主导作用 ;

Effects of mixed cropping of maize and peanut on the Fe nutrition of peanut plant and the available Fe content in the rhizophere of peanut were studied by pot experiment in sterilized soil. The results indicate that mixed cropping of maize and peanut can significantly improve the chlorophyll and active Fe contents in the young leaves of peanut, and the total Fe content of peanut shoots and the active Fe content in the rhizophere of peanut are also enhanced at the R_2 stage. Mixed cropping plays an important role in the improvement of the Fe nutrition of peanut. Soil sterilization can only improve the Fe nutrition of peanut at earlier growing stage.
