图5 不同时期灌水处理对吐丝期春玉米穗位叶光合速率(A)和开花吐丝间隔期(B)的影响 图中不同字母代表处理间差异显著(P < 0.05); CK、IV6、IV12、IS、IS15分别代表不灌水对照、拔节期、大口期、吐丝期和吐丝后15 d灌水处理。

Fig. 5 Effects of irrigating at different growth stages on ear leaf photosynthesis at silking (A) and ASI (B) in spring maize The different letters above the bars are significantly different among the different treatments at the 0.05 probability level; CK, IV6, IV12, IS, IS15 indicate the control without irrigation, irrigating at when the 6th and 12th leaf collar is visible, silking and 15 day after silking stage, respectively.
