【摘要】 采用盆栽试验方法,研究了包膜缓释铁肥防治花生黄化的效果。结果表明,施用包膜缓释铁肥后,花生产量处理间差异达极显著水平,并影响花生体内活性铁和叶片中叶绿素含量。花生荚果产量与苗期新叶活性铁、叶绿素含量和开花下针期活性铁和叶绿素含量呈显著或极显著正相关。更多还原

【Abstract】 The effect of Coated-Release-Iron Fertilizers (CRIFs) on iron-deficiency chlorosis was studied by pot experiment. The results showed that yields increased significantly after applying CRIFs. Application of CRIFs affected peanut yield by the increase of chlorophll content and active iron content in young leaves. Furthermore, there was positive correlation between yields at maturity and chlorophyll or active iron content in young leaves, and the differences in yields of CRIFs treatments and chlorophyll or active iron content in youngest leaves were significant.更多还原
