摘要
以大豆品种高丰1号为试材,采用田间试验方法研究了微量元素水溶肥料对大豆生物学性状及产量的影响。结果表明:微量元素水溶肥料对植株密度、单株分枝数、单株有效荚数、百粒重、单荚粒数都有显著影响。分别比常规对照和清水对照增产7.0%、23.8%,达到了显著和极显著差异,可进一步示范应用。
Taking soybean variety of Gaofeng No.1 as experiment material,the effects of water-soluble trace element fertilizer on soybean biological characters and yield were studied by field experiment.The result showed that the water-soluble trace element fertilizer had a significant effect on plant density,branch number,efficient pods number per plant,100-seeds weight and grain number per pod.Compared with CK1 and CK2,the yield could increase by 7.0% and 23.8%,respectively.The difference achieved significant and very significant level.Therefore,water-soluble trace element fertilizer was worthy of further application.
