以Y两优9918为供试品种,比较研究了长期淹水与间歇灌溉对头季和再生季产量与镉积累转运的影响。结果表明,间歇灌溉显著提高水稻有效穗数和千粒重,使头季稻增产6.35%,再生季增产23.33%,两季合计增产11.83%。灌溉...展开更多 以Y两优9918为供试品种,比较研究了长期淹水与间歇灌溉对头季和再生季产量与镉积累转运的影响。结果表明,间歇灌溉显著提高水稻有效穗数和千粒重,使头季稻增产6.35%,再生季增产23.33%,两季合计增产11.83%。灌溉方式对再生季产量各节位贡献的影响不大。间歇灌溉显著提高土壤有效镉含量、头季与再生季植株各器官镉含量,且成熟期各器官镉含量增幅有差异,头季表现根>茎>穗>叶,而...

The effects of long-term flooding and intermittent irrigation on yield and cadmium accumulation and transport in main crop rice and ratooning rice were compared with Y Liangyou 9918 as the material.The results showed that intermittent irrigation significantly increased ...MORE The effects of long-term flooding and intermittent irrigation on yield and cadmium accumulation and transport in main crop rice and ratooning rice were compared with Y Liangyou 9918 as the material.The results showed that intermittent irrigation significantly increased the number of effective panicles and 1000-grain weig...
