摘要
旨在筛选适宜机收再生稻栽培的杂交籼稻品种,以晶两优丝占等13个品种为研究对象,通过小区比较试验,从生育期表现、主要农艺性状、丰产性、再生能力表现等方面进行研究和综合分析.结果表明,晶两优丝占等5 个品种综合性状表现优势明显,建议重点推广;隆两优晶占等3个品种再生能力较弱,但丰产性好,建议适度推广;创两优茉莉占等 3 个品种再生能力较弱,丰产性一般,但稻米品质优,建议小规模试验种植.
Abstract
The aim was to screen hybrid Indica rice varieties suitable for machine-harvesting and regrowing rice cultivation.Thirteen varieties,such as Jingliangyousizhan were selected as the research subjects.The comprehensive analysis was carried out from the aspects of growth peri-od,main agronomic characters,high yield and regeneration ability through the plot comparison test.The results showed that 5 varieties,such as Jingliangyousizhan,had obvious advantages in comprehensive characters,which were suggested to be promoted;Longliangyoujingzhan and other 2 varieties had relatively weak regeneration ability,but had high yield,so they were suggested for moderate promotion;Chuangliangyou-molizhan and other 2 varieties had relatively weak regenerative capacity and moderate yield,their rice quality were excellent and pilot cultiva-tion was recommended.
