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。

The experiment was did in Liaocheng of west Shandong Province from 2009 to 2013 with ‘Lumianyan 28’ which widely popularized and applied in produc-tion as test materials. The author discussed the influence of meteorological factors change on cotton yield characteristic in different years. The results were as fol ow:firstly, the accumulated temperature change was not significant in growth period, the coefficient of variation of sunshine hour was up to 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 cor-related, al reached significant level. It was showed that precipitation was the key meteorological conditions affecting cotton production.
