图3 不同磷水平下玉米与大豆间作对大豆不同组织磷素浓度的影响 缩写和处理同表1。不同大小写字母分别表示在P50和P100水平下单作与间作之间的差异显著性(P < 0.05)。

Fig. 3 Effects of maize and soybean intercropping on P concentration of soybean organs under different P rates Abbreviations and treatments are the same as those given in Table 1. Different uppercase and lowercase letters mean the significant difference between monocropping and intercropping at the 0.05 probability level under P50 and P100 rates, respectively.
