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.
