中文摘要: |
采用数理统计和多元回归方法,主要分析了临夏地区油菜气候生态条件以及气候条件对油菜产量及其构成因素的影响。发现影响该地区油菜生长
发育的主要气候要素为降水、气温和日照;根据临夏地区双低油菜不同生长阶段所需气候条件,把双低油菜从春播到成熟,划分为五个生育期,建立了气候生态适生种植区划综合指标
体系和各生育期时空动态气候预测模式,实现双低油菜产量气象预测。 |
英文摘要: |
Using mathematical statistic method, we analysed physiological characteristics and requirements of the ecological climate condition to rape yield in Linxia. The results showed that the precipitation, temperature and sunshine coditions were main climatic factors affecting the growth of rape. According to the requirements to climatic conditions at different growth stages of double-low rape, we divided its growth period into 5 stages from sowing to harvest, and then established a system of suitable conditions for rape growth a
nd a model of forecast of spatial and temporal dynamics which realized the prediction of rape yield. |
