| 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 was carried out in oasis irrigation area of Hexi, and studied on intereropping wheat photo-synthetic characteristics during the filling stage in the water and fertilizer coupling condition. The results indi-cated that variation of photosynthetic characteristics were different in the different water and fertilizer condi-tions. Irrigation quantity (5550 3/hm2) combined with other treatments of fertilizer were better than other treat-ment including photosynthetic characteristics and WUE. Leaf photosynthesis rate of intercropping wheat was in positive correlation with the WUE. Optimum scheme of fertilizer and water management were irrigation water 5550 3/hm2, nitrogen 420kg/hm2or irrigation water 5550 3/hm2, nitrogen 630 kg/hm2. |
