图2. 不同种植模式下单株干物质积累速率和积累量
不同小写字母表示P<0.05下差异显著。柱状图上的数字表示该生育时期与上一生育时期之间的干物质积累速率。玉米的V3,V4,V6,V12,R1,R3和R7分别对应3叶期,4叶期,拔节期,大喇叭口期,吐丝期,灌浆期和成熟期。大豆的V3,V4,V5,R2,R5和R7分别对应苗期,分枝前期,分枝后期,盛花期,鼓粒期和成熟期。下同

Fig. 2. The per plant dry matter accumulation rate and amount under different planting patterns
Different small letters mean significantly different at P<0.05. The number on the column indicates the rate of dry matter accumulation between the growth period and the previous growth period. V3, V4, V6, V12, R1, R3 and R7 of maize correspond to the three-leaf,four-leaf stage, jointing, big flare, silking, filling, and maturity stage, V3, V4, V5, R2, R5 and R7 of soybean correspond to the seedling, early branching, late branching, flowering, filling, and maturity stage. The same as below
