请各位高手能否帮小弟修改润色一下我的英文摘要，感激不尽！ Taking single plant of corn (Zea mays) as research object, this study used an indoor rainfall simulator, and systematically measured the corn stemflow amount in different rainfall intensities and different test phases. The results showed that the mean ratio between stemflow and total ranfall is 65%. The stemflow amount from corn increased as corn leaf area and rainfall intensity increased, stemflow ratio increased as the leaf area increased, but not changed significantly as the increased rainfall intensity. Models of corn stemflow were constructed by the analysis of the relationship, including a theoretical model, a semi-empirical model and an empirical model. These three models are applicable to estimate the corn stemflow in the different growth stages and achieve the desired accuracy requirements which has been tested and verified. The semi-empirical model is more simple and accurate in the actual measurement and application. Models of stemflow constructed in this study can provide a calculation method for those who study water redistribution, soil moisture movement and soil erosion, and meanwhile provided theoretical guidance for water balance in irrigation and fine management of water and fertilizer in corn planting. |

| Taking single plant of corn (Zea mays) as the research objective and using an indoor rainfall simulator, this study systematically measured the corn stemflow amount in different rainfall intensities and different test phases. The results showed that the mean ratio between stemflow and total rainfall is 65%. The stemflow increased as corn leaf area and rainfall intensity increased. Besides, the stemflow ratio increased as the leaf area increased, but not changed significantly as the rainfall intensity increased. By the utilizing the above mentioned relationships, models of corn stemflow were established, including a theoretical model, a semi-empirical model and an empirical model. The three models are applicable to estimate the corn stemflow in the different growth stages and achieve the desired accuracy requirements, which has been tested and verified. The semi-empirical model is simple and yet accurate in the actual measurement and applications. Models of stemflow constructed in this study can provide a calculation method for those who study water redistribution, soil moisture movement and soil erosion. Moreover, they provide theoretical guidance for water balance in irrigation and fine management of water and fertilizer in corn planting. |
