摘要
以空育131为试材通过裂区试验,研究不同肥料和密度水平对水稻农艺性状、产量及产量性状的影响,结果表明,密度在行株距为30 cm×10 cm和30 cm×13 cm,产量相差不大,以行株距30 cm×13 cm在高肥力水平下产量最高,田间施肥量450kg/hm2比375 kg/hm2农艺性状有所改善,产量及产量性状有不同程度的提高,所以建议在生产中推广密度为30cm×13 cm并搭配施肥量450 kg/hm2。
The split-plot experiment was carried out to study the effect of fertilizer amount and density on agronomic traits, yield and yield components of rice variety Kongyu 131. The results showed that the agronomic traits were improved and the yield was increased when the fertilizer amount was increased from 375 kg/hm^2 to 450 kg/hmz whereas, the yields showed no difference between transplanting patterns 30×10 cm and 30×cm. The yield was the highest when the transplanting pattern was 30×13 cm accompanying with fertilizer amount 450 kg/hm^2.
