在不同肥水条件下,对间作小麦灌浆期的光合特性进行了研究,结果表明,间作小麦灌浆期的光合特性在不同肥水组合下的变化不同,灌溉量5550 m5/hm2条件下的各肥料处理对间作小麦光合特性和水分利用效率(WUE)的提高显著高于其他肥水处理.灌溉量5550m3/bm2条件下,间作小麦Pn与WUE呈正相关.肥水管理以灌溉量5550 m3/hm2、氮肥施用量420 kg/hm2或灌溉量5550 m3/hm2、氮肥施用量630 kg/hm2的方案最优.

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.
