| 摘 要： | 以青海省门源县为例,分析小油菜生育期气候变化规律.观测资料表明,小油菜生育期气温升高,气候变暖,4～8月降水量以每10年1.64～20.70 mm的幅度下降,9月降水以每lO年20.16 mm的幅度增加;气候变暖使小油菜播种期提前,成熟期推迟,生育期延长,为提高气候资源利用率和单位面积产量提供了保证;增温对各发育阶段的影响差异明显,除出苗至现蕾间发育进程加快外,其余各发育期生长发育出现迟缓变化;气候产量主要受4、6月和年平均气温及6月降水的影响.

| Abstract: | The regularity of climate change during the growing period of spring rape is analyzed, taking the Mengyuan county as an example. The result shows that the temperature is rising during the growing period of spring rape in Mengyuan, and precipitation is dropping at a rate of 1.64 of 20.70 mm per 10 years from April to August and rising at a rate of 20.16 mm per 10 years in September. The climate warming advances the seeding date and the mature stage of spring rape, lengthens the growth season, improves the use efficiency of climate resources, and enhances the output per unit in average. The influence of climate warming at each growth stage varies, and all growth stages are postponed except the seedling stage. The climatic yields are influenced mainly by temperature of April and June, annual mean temperature, and precipitation of June. |
