| 摘 要： | 通过大面积踏田调查,分析了水稻不同苗质、不同品种、不同种植方式灭顶受淹后的主要性状及受淹时间与产量的关系.结果表明:无论是杂交籼稻还是常规粳稻,受淹后壮秧的耐淹性好于弱秧和中间素质的秧苗.常规梗稻比杂交籼稻耐水淹,其茎蘖存活数、绿叶数均多于杂交籼稻.粳稻中,中熟中粳与迟熟中粳耐淹程度相似.手插、机插、直播3种种植方式中,手插秧苗的存活茎蘖数和绿叶数较多,耐淹性较好.淹水后水稻生育进程推迟.3种种植方式中,水稻均随灭顶受淹时间的延长,茎蘖存活数、绿叶数显著减少.水稻减产程度与淹水天数呈极显著正相关,淹水对产量的影响主要表现为降低有效穗数和每穗实粒数. |

| Abstract: | In 2006,the main properties of the submerged rice of different varieties,seedlings and cultivation styles,and the yield connection to the submergence time were studied by investigating the submerged rice paddy in Jinhu county.The results showed that the resistance to submergence of Japonica was greater than that of India,vigorous seedling was greater than puny seedling,transplanting by hand was greater than direct sowing and transplanting by machine.The rice that drowned not out of 4 day could resume,yield ... |
