- 摘要:
- 选用水稻品种空育131和牡丹江27，探讨了氮、钾、镁肥配比对水稻产量及稻米品质的影响。随着氮、钾、镁肥配比的变化，水稻在产量和米质上存在差异。不同的氮、钾、镁肥配比对2个品种产量影响总体趋势一致，只是在程度上有所不同，表明肥效应对2个品种的特性表达没有影响。同时，随着氮、钾、镁肥施用量的变化，籽粒蛋白质含量、直链淀粉含量、糙米的胶稠度等均有不同程度的改变，说明合理的氮、钾、镁肥管理措施可在一定程度上改善稻米品质。
- Abstract:
- In this study，Kongyu 131 and Mudanjiang 27 were used，effect of different ratio of nitrogen and potassium and magnesium fertilizer on rice yield and quality of grain had been investigatedWith the changing of ratio of nitrogen and potassium and magnesium fertilizer，there were differences in rice yield and qualityDifferent ratio have the same general trends on yield of the two varieties，difference only in degree，that was to say，the fertilizer response have no effect on the characteristics expression of the two speciesAt the same time，with the changing of their ratio，protein content and amylose content and gel consistence of grain have been changing in different degree，so appropriate management of nitrogen and potassium and magnesium fertilizer can improve the quality of grain to some extent
