研究施肥模式对水稻叶绿素含量及荧光参数的调节作用,对提高水稻光能利用效率及籽粒产量具有重要意义。本研究以水稻品种赣929为试验材料,比较长期定位施磷钾肥(PK)、施氮磷钾肥(NPK)、等养分条件下70%氮磷钾肥配合施用30%有机肥(70F+30M)、50%氮磷钾肥配合施用50%有机肥(50F+50M)、30%氮磷钾肥配合施用70%有机肥(30F+70M)条件下水稻叶绿素荧光参数和产量变化特征。结果表明,水稻旗叶叶绿素含量从齐穗期到成熟期呈下降趋势,且表现为30F+70M>50F+50M>70F+30M>NPK>PK。水稻叶绿素荧光参数Fv/Fm随水稻生育期的推进呈降低趋势,其中PK处理Fv/Fm值最低,而施氮处理比不施氮处理Fv/Fm值增加了2.85%~4.18...

The regulating effect of different fertilization modes on the chlorophyll content and fluorescence parameters of rice is of great significance for the improvement of light use efficiency and grain yield of rice. In this research, the characteristics of variation of chlorophyll fluorescence parameters and yield in rice under long-term located fertilization with the treatments of phosphate and potash fertilizer (PK), nitrogen, phosphate and potash fertilizer (NPK), 70% NPK fertilizer mixed with 30% organic manure (70F+30M), 50% NPK fertilizer mix...
