研究不同灌溉条件下水稻植株对氮素的吸收和利用。结果表明，在研究条件下，薄浅湿晒和间歇灌两种灌溉方式有利于水稻形成健壮的根系、增强吸氮能力，有利于氮素向生长中心转移，增加生长后期叶面积指数和叶片含氮量，提高水稻产量。 To study nitrogen uptake and utilization of rice plants under different irrigation conditions. The results showed that under the conditions of the study, two kinds of irrigation methods, thin and light wet and intermittent irrigation, were conducive to the formation of robust root system in rice and enhanced the ability of nitrogen uptake, which was conducive to the transfer of nitrogen to the growth center and increased the leaf area index and leaf content Nitrogen content, increase rice yield.
