【摘要】 黑龙港地区是黄淮海平原的干旱中心,四季均可发生干旱,尤以春旱最严重;这里辐射资源丰富,但形成的作物产量不高;本文引入相对光合速率、呼吸消耗率和水份影响函数,分别对黑龙港地区农作物的光能生产潜力、光温生产潜力和气候生产潜力进行了计算。更多还原

【Abstract】 Heilonggang areas are the main drought core of the Hwang-Huai-Hai plain, the drought may happen in four seasons. The Solar radiation resources are Abundant, but the yield of the crops are poor. The relative photosynthetic rate, the respiration consumption rate and the moisture affecting function is inducted. The author have estimated radi-ant potential productivity, radiant-tempe-rature potential productivity and the climatic potential productivity of the crops, respectively.更多还原
