摘要： 本试验在河西绿洲灌区进行，研究水肥耦合条件下间作小麦灌期浆光合特性对其的响应。结果表明，间作小麦灌浆期的肥水组合以灌溉量370m3/亩、N肥28kg/亩，370m3/亩、42kg/亩和450m3/亩、28kg/亩这3个肥水组合的光合特性表现较为突出。不同的水肥处理其中，370m3/亩的灌溉水平与其他肥料水平相结合或28kg/亩（N肥）的肥料水平与其他灌溉水平相配合具有一定的节水性且光合特性也良好。

Abstract: The test is carried out in oasis irrigation area of hexi, and study the response of intercropping wheat photosynthetic characteristics during the water and fertilizer coupling condition. The results indicate that photosynthetic characteristics of three water coordinating fertilizer are better than others during the filling stage of intercropping wheat. They are 370m3/mu(irrigation quantity) 28kg/mu(fertilizer rate), 370m3/mu、42kg/mu and 450m3/mu、28kg/mu. Under different treatment with fertilizer and water, irrigation quantity (370m3/mu) combined with other treatments of fertilizer or fertilizer rate (28kg/mu) combined with other treatments of water showed not only good water saving ability but also good photosynthetic characteristics.
