| Abstract: | 【Objective】To investigate the effects of nano-and ion-magnesium on rice grain yield,yield formation and nitrogen uptake and utilization.【Method】A pot experiment was conducted to study the effects of nano-magnesium and ion-magnesium on rice yield formation and nitrogen accumulation and utilization under nitrogen application rates of 0 kg/hm2,180 kg/hm2and 270 kg/hm2,respectively.【Result】Application of nano-magnesium and ion-magnesium can effectively increase rice yield at the same N application level.The yield of rice treated with nano-magnesium were significantly higher than that treated with sodium magnesium.Moreover,the same trend was also observed in LAI and the accumulation of dry matter in the late stage of rice growth.The application of nano-magnesium could improve the dry matter formation in the late stage of rice growth,increased the SPAD value,photosynthetic potential and net photosynthetic rate of the flag leaf after heading,promoted the synthesis of rice dry matter and the accumulation in grains,and finally achieved the goal of increasing rice production.At the same level of nitrogen fertilizer application,the application of nano-magnesium and ionic-magnesium increased the nitrogen concentration and nitrogen accumulation in rice stems,leaves,and grains,and promoted the partial productivity of nitrogen fertilizer,nitrogen agronomic utilization rate,nitrogen physiological utilization rate and nitrogen absorption and utilization.These promotion effects of nano-magnesium were better than that of ionic-magnesium in this study.【Conclusion】In summary,nano-magnesium can be used as a fertilization measure for green and high-efficiency rice cultivation. |
