图4 不同时期灌水处理对春玉米生物量的影响 图中不同字母代表处理间差异显著(P < 0.05); V12、R1、R6分别代表大口期、吐丝期、成熟期; 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. 4 Effects of irrigating at different growth stages on biomass in spring maize The different letters above the bars are significantly different among the different treatments at the 0.05 probability level; V12, R1, R6 indicate the 12th leaf collar is visible, silking and maturity stage, respectively; CK, IV6, IV12, IS, IS15 indicate the control without irrigation, irrigating at V6, V12, R1, and R6, respectively.
