图4 机施模式下5—40 cm各深度间MITC溶度 a：气体MITC溶度MITC gas solubility;b：土壤残留MITC溶度MITC soil residual solubility。安徽-40 Anhui-40：安徽试验地棉隆用量40 g·m-2 Dazomet application dosage was 40 g·m-2 in Anhui experimental field;山西-40 Shanxi-40：山西试验地棉隆用量40 g·m-2 Dazomet application dosage was 40 g·m-2 in Shanxi experimental field;河北-40 Hebei-40、河北-60 Hebei-60：河北试验地棉隆用量分别为40、60 g·m-2 Dazomet application dosage was 40, 60 g·m-2 in Hebei experimental field, respectively。MITC气体及土壤残留溶度为3个重复样本的平均值和标准误;柱上小写字母代表差异显著性水平（P=0.05）Mean values and standard errors of MITC solubility were calculated by three replaces. Lowercase letters on the bars represent the level of significance difference (P=0.05)
