图2 不同灌溉量、种植密度和品种的产量及耐旱性分类 红色横向虚线表示D1密度条件下W1、W2灌溉水平的平均产量；蓝色横向实线表示D2密度条件下W1、W2灌溉水平的平均产量。红色纵向虚线表示D1密度条件下W3灌溉水平的平均产量；蓝色纵向实线表示D2密度条件下W3灌溉水平的平均产量。

Fig.2 Yield and drought tolerance classification of different irrigation amounts, planting densities, and cultivars The red horizontal dashed lines indicate the average yields under W1 and W2 irrigation amounts at D1 planting density, while the blue horizontal solid lines indicate the average yields under W1 and W2 irrigation amounts at D2 planting density. The red vertical dashed line indicates the average yield under W3 irrigation amount at D1 planting density, and the blue vertical solid line indicates the average yield under W3 irrigation amount at D2 planting density.
