摘要： 为了研究温度和降水对玉米生长发育及产量的影响，为合理利用不同气候条件保证玉米生长提供依据，采用大田试验数据和气候资料，分析了辽宁地区玉米生长发育及产量特征对温度、降水和热量条件的响应。结果表明：玉米各生育期生长天数，七叶—拔节期受平均温度影响，三叶—七叶期受降水量影响，播种—三叶期和乳熟—成熟期受前期积温影响；降水量与播种—三叶期的玉米地上干重相关显著，平均气温与三叶—七叶期的叶面积指数相关显著，前期积温对玉米生物量增长影响最大；在同等积温增加条件下，辽东地区地上生物量增加最多，辽西地区最少。不同生育期玉米受到播期和气候条件的影响程度不同，不同地区间的果实性状及产量差异较大。

Abstract: In order to study the effect of temperature and precipitation on maize growth and yield, and provide reference for ensuring maize growth under different climate conditions, this paper analyzed the growth and yield in different climatic conditions of Liaoning and its response to air temperature, precipitation and heat based on field experiments and climate data. The results showed that maize growing days were influenced by the average temperature from seven leaf to jointing stage, influenced by the precipitation from three leaf to seven leaf stage, and influenced by the accumulated temperature from sowing to three leaf and milk to mature stage. The correlation between precipitation and maize shoot dry mass was significant from sowing to three leaf stage, the correlation between leaf area index and average temperature was significant from three-leaf to sevenleaf stage. The accumulated temperature was the most significant factor of maize biomass. In the same increasing accumulated temperature, the maize biomass increased most in Eastern Liaoning and least in Western Liaoning. Influenced of sowing time and climatic conditions on the maize growth in different periods was different, and the fruit characters and yield differs significantly in different regions.
