宁夏农业生产潜力模型建立

Establishment of Ningxia Agricultural Productivity Potential Model

根据已建立的作物生产潜力模型,对宁夏主要农作物生产潜力进行了计算,并分析了影响作物现实生产力的因素。结果表明,宁夏小麦、玉米现实生产力分别达到了气候生产潜力的52%、67%,平均为59.5%,说明各作物的现实生产力还有较大的提高空间;在可控环境因素中,水分对作物气候生产潜力的影响最大,温度次之。

According to the established crop productivity potential model, the productivity potentials of main crops in Ningxia are calculated, and the influence factors of the crop practical productivity are analyzed. The results show that the practical productivities of wheat and corn are up to 52% and 67% of the climate productivity potentials respectively,and the average is 59.5%. It means that the practical productivities of the crops have a large room to be improved. In the controllable environment factors, the water content has the biggest impact on the crop climatic potential productivity,and the temperature rows second.
