摘要：

采用大田试验方法,以淮稻5号、津稻263、盐粳7号、镇稻99、徐稻4号和金粳1号为试验材料,分5期播种,研究了不同播期条件下各品种的生育期、产量和品质变化,探讨用粳稻做中稻在江汉平原的适宜栽培期。结果表明,供试品种全生育期随播期推迟而缩短。各期产量受播期影响较小,产量构成要素中,各品种不同播期条件下毎穗总粒数差异不显著,结实率整体随播期推迟升高,千粒重变化较小。稻米品质随播期的推迟无显著变化,稻米品质主要参考因子中,糙米率和精米率相同品种各期之间无显著差异,整精米率、垩白度、直链淀粉含量随播期的推迟呈上升趋势。

摘要：

The suitable cultivation period of japonica as middle-season rice in Jianghan Plain was studied. 6 japonica rice varieties including Huaidao No.5, Jindao 263, Yanjing No.7, Zhendao 99, Xudao No.4 and Jinjing No.1 were used. The changes of growth period, yield and quality were studied under condition of 5 different sowing dates. The results showed that growth period of six rice varietied was shorten by the delay of sowing date. The yield of each variety was less affected by sowing date. In yield components, the total grain number per panicle had no differences. Rate of seed setting increased.1000-grain weight changed little in each variety with the delay of sowing date. The quality of the tested cultivars did not change very much. Among the main reference factors of rice quality, there were no significant differences about the brown rice rate and the refined rice rate. The whole refined rice rate, chalkiness degree and amylose content was increased with the delay of sowing date.
