摘　　要：通过探讨不同灌溉方式下施肥量对水稻生长质量的影响,以期为水稻的优质高产高效栽培提供理论依据。研究选取了常规灌溉、土壤浸润灌溉、控制灌溉三种方式,并设置了三种不同的施肥量水平,通过田间试验观察了水稻的生长状况。研究结果表明,不同灌溉方式下施肥量对水稻生长质量的影响机制存在差异,相比常规灌溉、土壤浸润灌溉,控制灌溉方式下水稻的生长质量更为稳定。在控制灌溉条件下,高量的施肥可以显著提高水稻的分蘖数、株高指标。因此,为了实现水稻的优质高产高效栽培,应根据具体的灌溉方式选择合适的施肥量。By exploring the effect of fertilizer application rate on the growth quality of rice under different irrigation methods,this study aims to provide theoretical basis for the high-quality,high-yield,and efficient cultivation of rice.The study selected three methods:conventional irrigation,soil infiltration irrigation,and controlled irrigation,and set three different levels of fertilizer application.The growth status of rice was observed through field experiments.The research results indicate that there are differences in the impact mechanism of fertilizer application on rice growth quality under different irrigation methods.Compared with conventional irrigation and soil infiltration irrigation,the growth quality of rice is more stable under controlled irrigation methods.Under controlled irrigation conditions,high fertilization can significantly increase the tiller number and plant height indicators of rice.Therefore,in order to achieve high-quality,high-yield,and efficient cultivation of rice,the appropriate amount of fertilizer should be selected according to the specific irrigation method.
