| 摘 要： | 对杂交稻中优218不同灌溉方式和氮肥管理下水稻生长和根际环境的变化进行研究,结果表明,水稻好气灌溉条件下各施肥处理产量均高于传统灌溉处理,产量比淹水灌溉增产10.5%~11.3%,主要表现在每穗粒数增加而提高产量。好气灌溉与淹水灌溉比较各生育期地上部干物重和叶面积指数均增加,土壤氧化还原电位提高,放线菌数量显著增加。增加有机肥降低土壤氧化还原电位和提高放线菌数量,在好气灌溉条件下施相同氮素有机肥放线菌数多于化肥。

| Abstract: | A field experiment was conducted to investigate the effects of irrigation and fertilization on the growth and root environment of hybrid rice.The results showed: The yield of rice grain was increased by 10.5%~11.3% under aerobic irrigation than under flooding irrigation,relying on more grain number per panicle mainly.Aerobic irrigation promoted dry matter and LAI at every growth stage as compared with traditional irrigation under different management of N Fertilizer.Both Eh and actinomyces of the soil under... |
