图4 不同施磷量和遮光处理对花后大豆叶片气体交换参数的影响 不同字母表示处理间差异在0.05水平差异显著。R1: 始花期; R3: 结荚初期; R5: 鼓粒初期; R7: 成熟初期。处理同表1。

Fig. 4 Effects of different phosphate fertilizer application and light environment treatments on gas exchange parameters of soybean leaf after anthesis Different letters indicate significant differences among treatments at the 0.05 probability level. R1: beginning of flowering; R3: beginning of podding; R5: beginning of grain filling; R7: beginning of maturity. Treatments are the same as those given in Table 1.
