摘　　要：以宜香优2115为材料,在正安、贵阳和兴义试验点,设置了S1、S2和S3三个播期和常规施肥(CF)、精确施肥(AF)施肥模式,研究播期和施肥模式对宜香优2115产量及品质的影响。结果表明,播期对于产量和品质的影响三个地点趋势不一致,正安点和贵阳点S3产量最高,兴义点S1处理产量最高。精确施肥模式会显著提高正安、贵阳和兴义点的水稻产量,并提高稻米的加工品质和营养品质。Three sowing dates(S1,S2 and S3) and two fertilization modes(conventional fertilization(CF) and precise fertilization(AF)) were set up to study the effects of sowing date and fertilization mode on yield and quality of Yixiangyou 2115 at Zheng’an,Guiyang and Xingyi experimental sites.The results showed that the effects of sowing date on yield and quality were inconsistent in three locations.The yield of S3 was the highest in Zheng’an and Guiyang,and the yield of S1 was the highest in Xingyi.Precision fertilization mode could significantly improve rice yield in Zheng’an,Guiyang and Xingyi and improred the processing quality and nutritional quality of rice.
