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。
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 period,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;Chuangliangyoumolizhan and other 2 varieties had relatively weak regenerative capacity and moderate yield,their rice quality were excellent and pilot cultivation was recommended.
