摘要： 本文研究了日本水稻旱育秧与本地水育秧栽培技术不同移栽叶龄对秧苗素质和产量的影响。结果表明:3.5叶移栽的旱育秧亩产368.4kg,比同期移栽的水育秧亩增47.7kg,经方差分析差异达到极显著水平,旱育秧根系发达白根多,秧苗矮健,分孽早,低位分蘖多,有效穗增加,穗大粒多,成熟期提早1至3天,社会经济效益好。

Abstract: The effects of rice Seedling culture under dry condition and wet condition were compared by examining their seedling qualities and yields.The suitable leaf age of transplauting was also studied.The results showed that the seedling culture under dry condition has the merits of vigorous root growth with more white roots, shorter and healthy seedling earlier tiooering with lower tillering nodes, more productive Paniclues, more grains per panicle and 1-3 days earlier maturing.Transplauting at 3.5 leaf age, the dry coudltion can produce 47.7kg per mu more than that of wet comdition and th difference is significant at 1%.
