摘要: 以生产上大面积推广应用的‘鲁棉研28号’为试材,探讨年际间气象因子变化对棉花产量的影响。结果表明,年际间棉花生育期内的积温变化不显著,日照时数间的变异系数为7.4%,降水量的变异系数达到18.4%;日照时数与籽棉产量、霜前籽棉产量、皮棉产量呈正相关;降水量与籽棉产量、霜前籽棉产量、皮棉产量呈负相关,均达到显著水平,表明降水量是影响棉花产量因素的关键气象条件。

Abstract: The experiment was carried out in Liaocheng of west Shandong Province from 2009 to 2013 with‘Lumianyan 28’, which widely applied in production, as the test material. The author discussed the influence of meteorological factors change on cotton yield in different years. The results showed that: firstly, the accumulated temperature change was insignificant in growth period, the coefficient of variation of sunshine hour was 7.4%, the coefficient of variation of precipitation was up to 18.4%; secondly, sunshine hour and seed cotton yield, seed cotton yield before frost, lint yield were positively correlated; last, precipitation and seed cotton yield, seed cotton yield before frost, lint yield were negatively correlated, all reached significant level. It was showed that precipitation was the key meteorological factor affecting cotton production.
