淮北油菜一般年份的安全越冬,早已被大面积栽培结果所证实。但就冷冬年越冬,合理利用气候资源,提高单产以协调粮、油、多种经营之间争地矛盾,需要进一步研究。为此,我们于1980、1981两年进行了油菜安全越冬农业气象试验,并对苗期气象条件与产量的关系进行了统计学分析,现将分析结果初报如下: Huaibei rape general winter safety, has long been confirmed by large-area cultivation results. However, it is necessary to further study the wintering winter in the cold winter, the rational use of climatic resources and the improvement of yields to coordinate the contradictions between grain, oil and diversified operations. To this end, we carried out winter rapeseed overwintering agricultural meteorological experiments in 1980 and 1981, and conducted statistical analysis on the relationship between the meteorological conditions and yield at the seedling stage. The results of the analysis are as follows:
