Abstract:
      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.
