图4 施用脱硫废弃物后大田种植油葵苗期、成熟期叶片细胞膜透性(%)的年际变化(平均值±标准误差, n = 5)。 同一年份同一生育期中不同字母表示在0.01水平上差异显著(p < 0.01); F (0.01) = 4.43。CK、T1、T2、T3、T4, 同表2。

Fig. 4 Annual variation of leaf cell membrane permeability (%) in oil-sunflower field trial after added desulfurated waste residue in seedling and maturity periods (mean ± SE, n = 5). Ma: maturity period; Se: seedling period. Different letters in the same year and period indicate significant difference at 0.01 level. F (0.01) = 4.43. CK, T1, T2, T3, T4, see Table 2.
