[目的]研究气象因子与油菜产量及其构成的关系。[方法]采用田间试验设计，通过 Excel表格汇总整理从气象局获得气象资料，在 DPS数据处理系统下利用逐步回归分析研究气象因子与油菜产量及其构成的相关性。[结果]单株有效角果数与苗期气候因子关系密切，与苗期降雨量显著正相关，而与平均气温和日照时数呈显著负相关。每角粒数与苗期降雨量呈正相关，而与苗期气温和花期日照时数负相关。千粒重与苗期日照时数正相关、与花期降雨量负相关。[结论]栽培上应增加地表覆盖等措施保证土壤适宜的水分条件，促进幼苗生长，保持田间通风透光性好，减少降雨对油菜开花的影响。通过壮苗培育提高商品油菜籽产质量。

[Objective] The aim was to research relationship of meteorological factors with rapeseed yield and yield components. [Method] A field test was carried out, with meteorological information col ected from local Meteorological Administration. The data were then through statistical work and regression analysis was made on correlation of meteorological factors with yield and yield components supported by DPS. [Result] The number of pod per plant is closely related to meteorological fac-tors in seedling stage. Specifical y, the number is of positive correlation with precipi-tation in seedling stage and of negative correlation with average temperature and sunshine hour. The number of grain per pod is of positive correlation with precipita-tion in seedling stage and negative correlation with temperature in seedling stage and sunshine hour in anthesis. Thousand-seed weight is of positive correlation with sunshine hour in seedling stage and negative correlation with precipitation in seedling stage. [Conclusion] Moisture of soils should be guaranteed by surface cov-erage in order to promote seedling growth, maintain ventilation in fields and reduce effects of rainfal on rapeseed flowering.
