摘要
为了提高油菜产量和质量,制备了微量元素水溶肥料(水剂)含有氮、磷、钾和硫[(N+P2O5+K2O+S)总量≥50 g/L],微量元素以硼、锌为主[(Zn+B+Cu+Fe+Mn+Mo)总量≥100 g/L]。在油菜上喷施的应用效果表明,该肥料能改善油菜生物学性状,优化油菜的产量结构,提高油菜的产量,产量可达9.23 kg/hm2(138.5 kg/亩),比常规对照和清水对照分别增产7.6%和6.7%。
In order to raise production and quality of rape, water-soluble trace element fertilizer （ aqueous solution） is prepared, which contains nitrogen, phosphate, potassium and sulfur [ （ N ＋ P205 ＋ K20 ＋ S）total content≥50 g/L], and trace elements mainly are boron,zinc,etc. [ （Zn ＋ B ＋ Cu ＋ Fe ＋ Mn ＋ Mo） total content≥100 g/L]. Application effect of spraying on rape indicates that this fertilizer can improve biological characteristics of rape, optimize production structure and increase rape yield, the yield can amount to 9.23 kg/hm2 （138.5 kg/mu）. Compare with routine and clear water treatment, the yield has increased by 7.5% and 6.7% respectively.
