图3 两种施药方式下异硫氰酸甲酯气体溶度在不同深度土层（5—40 cm）中差异比较 a：安徽长丰,棉隆用量为40 g·m-2 In Changfeng, Anhui, the application dosage of dazomet was 40 g·m-2;b：山西运城,棉隆用量为40 g·m-2 In Yuncheng, Shanxi, the application dosage of dazomet was 40 g·m-2;c：河北满城,棉隆用量为40 g·m-2 In Mancheng, Hebei, the dosage of dazomet was 40 g·m-2;d：河北满城,棉隆用量为60 g·m-2 In Mancheng, Hebei, the dosage of dazomet was 60 g·m-2。其中蓝色柱子代表手撒,黄色为机施,柱子长度代表标准化后MITC溶度值,平均值误差及95%置信区间用线段长度表示（n=5）,样本间差异采用秩和检验（Welch’s t-test）The blue column represents hand-sprinkling and the yellow column represents machine application. Column length represents the MITC solubility value after standardization. The mean error and 95% confidence interval are expressed by the line segment length (n=5). Welch’s t-test is used for the difference analysis among samples。图5同The same as Fig. 5
