摘    要:加强花生气候生产潜力的开发利用,是提高当地花生生产的一个关键因子。通过鹰潭地区花生气候生产潜力模型,结合坡地实际产量资料,计算了花生气候生产潜力利用率(PUE),结果表明花生坡地PUE平均值为55.2%,上坡PUE平均值高于下坡2.7%,这对区分上下坡灌溉条件,努力提高花生气候生产潜力有较大参考意义。

关 键 词:花生  坡地  产量  气候  生产潜力  利用率  PUE

Study on the Utilization of Peanut Climatic Productive Potentiality on the Slope Land
Abstract:Yingtan hilly area is one of major bases for peanut production in Jiangxi Province. How to improve the climatic productive potentiality is one of local concerns about increasing peanut production. The climatic productive potentiality use efficiency (PUE) of peanut was calculated based on the model and actual yield data from slope land. The results showed the PUE for peanut on slope land is 55.2% on the average, with 2.7% higher on upper slope than lower slope. It provides some references to distinguish upper slope irrigation conditions from that of lower slope, and to achieve better climatic productive potentiality.
Keywords:peanut  slope land  yield  climatic productive potentiality use efficiency (PUE)
