【摘要】 本文通过对20个不同气象因子与黔草1号种子产量相关分析研究,结果表明:各气象因子与种子产量之间有一定的相关性,其相关作用差异明显。其中,春季均温与种子产量呈极显著正相关(p<0.01),≥10℃的积温和秋季均温与种子产量呈显著正相关(p<0.05),说明春季均温高、≥10℃的积温多、秋季均温较高对黔草1号增产较显著;在与黔草1号种子产量呈负相关的气象因子中,冬季日照时数与种子产量关系较大,说明冬季日照时数少对增产有利,反之亦然。更多还原

【Abstract】 Correlations of 20 meteorological factors and seed yield have been studied in the paper.The result show that the influence of each meteorological factors on seed yield was obvious difference,vernal mean temperature showed correlation with seed yield at significance level(p<0.01),≥10℃accumulated temperature and autumnal mean temperature showed correlation with seed yield at significance level(p<0.05),this showed that high vernal mean temperature, accumulated temperature and autumnal mean temperature have evident effects on increasing yield;among meteorological factors that negatively correlated with seed yield,hiemal daylight hours showed evident negatively correlation with seed yield at significance level,these showed that fewer daylight hours was benefit to increasing production of seed.更多还原
