播期对不同类型水稻生长及产量构成因素的影响
Effect of seeding time on growth and yield components in different rice types
摘要
Abstract
Effect of sowing date on rice growth and yield components were studied by sowing and transplanting on different dates in this study.The research were carried out in three rice types,named Liangyoupeijiu,6 Liangyou 9386 and IIyou 084.Rice growth and yield component indexes,such as chlorophyll,soluble sugar and nitrogen con-tent,were measured during heading stage and maturity stage.Results show that date of May 25 is the most suitable sowing time for Liangyoupeijiu and 6 Liangyou 9386,while the date of June 12 is the most suitable sowing time for IIyou 084.The sowing date has influence on panicles per plant,grains per panicle,seed setting rate,grain weight.The effect is significant on seed setting rate of Liangyoupeijiu,and grains per panicle of 6 Liangyou 9386. This research will provide theoretical basis and technical reference for climate resource utilization,reasonable arrangements of see-ding time and even rice yield improvement.关键词
