图3 栽培模式对夏玉米花后叶片气体交换参数的影响 SH: 超高产模式; HH: 高产高效模式; FP: 农户管理模式; R1: 吐丝期; R1+15: 吐丝后15 d; R1+30: 吐丝后30 d; R1+45: 吐丝后45 d。 *和**分别表示在0.05和0.01水平上处理之间差异显著。不同小写字母表示P < 0.05差异显著。

Fig. 3 Effects of cultivation modes on gas exchange parameters of summer maize leaves at post-flowering stage SH: super high yield mode; HH: high-yield and efficient mode; FP: farmer management mode; R1: silking stage; R1+15: 15 days after silking stage; R1+30: 30 days after silking stage; R1+45: 45 days after silking stage. * and ** indicate significant differences at P < 0.05 and P < 0.01, respectively. Different lowercase letters indicate significant difference at P < 0.05 among the treatments.
