| 摘 要： | 依据2006年在安徽省杂交中籼稻主产区利用地理与分期播种法得到的试验数据和相关气象资料,运用灰色关联分析方法探讨气象要素对杂交中籼稻产量及其产量构成因素的影响.结果表明,在移栽-始穗期,平均日照时间对有效穗数影响最大,在始穗-齐穗期,平均气温对结实率和千粒重以及平均相对湿度对有效穗数影响最大,在齐穗-成熟期,平均最低气温、平均日照时间和平均相对湿度分别对结实率、每穗总粒数和有效穗数影响最大.而对产量影响最大的是在始穗-齐穗时期的平均最低气温和空气相对湿度.

| Abstract: | The effects of meteorological factors on yield and its components of indica hybrid rice in main production area of Anhui Province were investigated using grey correlation method on base of the meteorology and test data obtained by geographical sowing and interval sowing experiments.The results showed that mean sunshine hours had the most significant impact on effective panicles from transplanting to initial heading stages;mean temperature and relative humid had the most significant impact on setting percent... |
