图1 大田磷肥处理对水稻籽粒植酸磷、总磷含量以及植酸磷/总磷比值的影响 标以相同小写字母的柱值差异未达到0.05的显著水平。LP: 低磷处理; MP: 中磷处理; HP: 高磷处理; PAP: 植酸磷; Total P: 总磷; PAP/total P: 植酸磷/总磷。

Fig. 1 Differences in PAP, Total P concentration (mg g-1), and PAP/total P among various phosphorus fertilizer levels in field experiment Bars indicated by the same letter among treatments are not significantly different at the 0.05 probability level. LP, MP, HP mean the low phosphorus level, medium phosphorus level, and high phosphorus level. PAP: phytic acid-phosphorus; Total P: total phosphorus; PAP/total P: phytic acid-phosphorus/total phosphorus.
