图4 2019—2020年不同种植密度对R1时期大豆叶片光合参数的影响 散点的密集程度代表2年重复试验间的差异大小,*、**和***分别表示在P<0.05、P<0.01和P<0.001水平上不同种植密度及不同种植模式间的差异极显著。下同

Fig. 4 Effects of different planting densities on photosynthetic parameters of soybean leaves at R1 in 2019-2020 The density of scattered spots represented the difference between two-year repeated trials. *, ** and *** indicated significant difference among different planting densities and different planting patterns at P<0.05, P<0.01 and P<0.001, respectively. The same as below
