昆明蚕豆气候因子适宜性分析(英文)

目的]分析昆明蚕豆气候因子适宜性。方法]该研究结合昆明蚕豆生理生态特征,建立了温度、降水和日照对蚕豆生长发育的适宜度模型,进而分析气象条件的适宜程度。结果]多年平均气候条件下,在蚕豆整个生育期内,温度和日照适宜度总体较高,降水适宜度较低,开花结荚期温度较低和降水不足是蚕豆产量形成的限制因子。对2013年蚕豆气象因子适宜度分析表明,2013年蚕豆温度适宜度和日照适宜度总体较高。降水适宜度除苗期在0.6以上外,其余生育期的水分适宜度都较低。结论]2013年蚕豆在整个生育期中综合气象条件为中等偏上水平。作物气候适宜度模型能客观反映气象条件对作物生长发育的适宜程度,可为提高气象服务质量提供了依据。

Climatic Factors Suitability Analysis of Broad Bean in Kunming

Objective] The aim was to analyze the suitability of climatic factors for broad bean in Kunming. Method] The suitability model of broad bean growth and development was established, involving temperature, rainfal , and sunshine, with consideration of bioecology characters of broad beans, in order to make further analysis of suitability of meteorological factors. Result] Under average climate condition, temperature and sunshine suitability kept higher in the whole growth stage, but rainfal suitability was lower. Hence, lower temperature and insufficient rainfal are limiting factors of broad bean yield. Based on analysis of meteorological factors in 2013, it suggested that temperature and sunshine suitability kept higher in 2013, but rainfal suitability only reached over 0.6 in seedling stage, with rest below. Conclusion] In the whole growth stage of broad bean in 2013, comprehensive meteorological factors kept middle or higher level and the suitability model reflects suitability of meteorological factors to crops in an objective way, which provides references for improving meteorological services.
