- Abstract:
- [Objective] The aims of this study are to explore the effect of short-term rainstorm on phosphorus loss of rice, clarify the utilization effect of rice phosphorus under straw and biochar return, and provide scientific basis for soil phosphorus management in paddy fields.[Methods] Based on pot experiment and artificial rainfall simulation, we set the rainstorm intensities respectively at 4 mm/h(20 h)and 80 mm/h(1 h), selected straw(NPK+S)and biochar(NPK+B)as two kinds of returning materials in order to analyze the effects of different treatments on phosphorus content, accumulation and apparent utilization efficiency of rice. [Results] Under the condition of short-time rainstorm, the addition of straw and biochar can improve the phosphorus content, accumulation, apparent utilization efficiency of rice. Compared with the NPK treatment, the NPK+B treatment increases the TP content of root by 41.84% and straw by 38.43%, the NPK+S and NPK+B treatments increase the phosphorus accumulation in the rice by 21.95% and 60.14%, the apparent utilization efficiencies of rice in the NPK+S and NPK+B treatments increase by 21.96% and 60.10%, all reach to the significant level. Under the condition of long-time rainstorm, compared with the NPK treatment, the NPK+S and NPK+B treatments increase the root TP content by 28.67% and 33.59%, the TP contents of the straw NPK+B treatment increases by 48.52%, NPK+S and NPK+B treatments increase grain TP content by 17.15% and 39.28%, NPK+S and NPK+B treatments increase phosphorus accumulation by 35.70% and 74.71%, apparent utilization efficiencies of NPK+S and NPK+B treatments increase by 35.66% and 74.70%, they all reach to the significant level. [Conclusion] Under different rainstorm intensity conditions, the addition of straw and biochar can effectively retain the phosphorus nutrient of rice, improve the apparent utilization efficiency of phosphorus, and reduce the risk of nutrient loss. The effects of adding biochar are better than those of adding straw. Moreover, based on the premise of the same amount of rainfall, the retention effects of long-time rainstorm are better than that of short-time rainstorm.
