图2 播期对不同熟期夏玉米干物质积累量的影响 不同小写字母表示同一生育时期不同播期间在5%水平显著差异。E：6月5日播期;N：6月15日播期;L：6月25日播期。V6：拔节期;V12：大喇叭口期;VT：抽雄期;R3：乳熟期;R6：成熟期。下同

Fig. 2 Effects of sowing date on dry matter accumulation of summer maize hybrids differing in maturities Different lowercase letters indicate that the difference between different sowing dates under the same growth stage is significant at 0.05 level. E: Sowing in June 5th; N: Sowing in June 15th; L: Sowing in June 25th. V6: Six-leaf stage; V12: Twelve-leaf stage; VT: Tassel stage; R3: Milk stage; R6: Maturity stage. The same as below
