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。 Pot experiments were conducted to study the effect of coated slow-release iron fertilizer on peanut yellowing. The results showed that the differences of peanut yield and yield were significant at the very significant level after application of coated slow-release iron fertilizer, and affected the content of chlorophyll in active iron and leaves of peanut. The peanut pod yield was significantly or very significantly positively correlated with the active iron and chlorophyll content of new leaf at seedling stage and the contents of active iron and chlorophyll at flowering stage.
