图1 不同耕作措施及水氮耦合模式下小麦干物质积累动态 NT: 免耕地膜两年利用; CT: 传统耕作; I2: 传统灌水(2400 m3 hm-2); I1: 传统灌水减量20% (1920 m3 hm-2); N3: 传统施氮(225 kg hm-2); N2: 传统施氮减量20% (180 kg hm-2); 传统施氮减量40% (135 kg hm-2)。误差线表示标准差(n = 3)。

Fig. 1 Dynamic of dry matter accumulation of wheat in different tillage practices and water-nitrogen coupling patterns NT: no tillage with plastic mulching; CT: conventional tillage with plastic mulching; I2: conventional irrigation (2400 m3 hm-2); I1: reduced 20% irrigation (1920 m3 hm-2); N3: conventional nitrogen application (225 kg hm-2); N2: reduced 20% nitrogen (180 kg hm-2); N1: reduced 40% nitrogen (135 kg hm-2). The error bar indicates standard error (n = 3).
