摘　　要：以2011年云南高产潜力鉴定水稻品种为试验材料,应用多种统计分析方法,研究水稻在超高产条件下各主要农艺性状间关系及其与产量间的关系。结果表明,水稻在超高产条件下,应适当控制全生育期,提高有效穗及穗粒数,才能达到更高产量。With high yield potential of rice varieties in Yunnan in 2011 as experimental materials,using a variety of means of statistical analysis,the relationship between the main agronomic traits and the relationship between yield and these agronomic traits in the super high-yielding conditions were studied. The results showed that： rice in super high-yielding conditions should appropriately control the growth period,improve effective panicles and grains per spike,in order to achieve a higher yield.
