摘要
试验结果表明,春优84在浙西南山区作单季晚稻种植,在5月20日至6月9日期间播种均可正常抽穗结实。不同播期处理间产量存在显著或极显著差异,以5月30日播种的处理产量最高;不同播期处理间日产量亦存在显著或极显著差异,以6月9日播种最高。随着播种期的推迟,齐穗期、成熟期也相应推后。
Field experiment was carried out to study the effects of sowing date on yield and economic characters of Chunyou 84.The results showed that Chunyou 84 in mountainous southwestern Zhejiang Province for single-season rice planting,sowing between May20 to June 9 can be normal heading.There were significant or very significant difference of yield and daily yield among different sow-ing date treatments.With the delayed sowing date,the heading stage and maturity stage accordingly postponed.
