图2 有机无机肥配施对晚稻旗叶叶绿素含量的影响 “FHS”表示齐穗期, “10DAFH”表示齐穗后10 d, “20DAFH”表示齐穗后20 d, “30DAFH”表示齐穗后30 d。处理缩写同表1。图柱上不同小写字母表示处理间差异显著(P < 0.05)。

Fig. 2 Effects of organic and inorganic combined fertilization on SPAD value of late rice flag leaves “FHS” shows full heading stage. “10DAFH”, “20DAFH”, and “30DAFH” showed 10, 20, and 30 days after heading stage respectively. Treatments described as in Table 1. Bars superscripted by different letters are significantly different among treatments at P < 0.05.
