图2 2015—2017年食葵全生育期0—30 cm土层土壤温度变化及显著差异性特征 CK：无秸秆隔层;S3：厚度3 cm秸秆隔层;S5：厚度5 cm秸秆隔层;S7：厚度7 cm秸秆隔层。图中数值为探头温度加权平均值。下同 图2-a表示的是食葵全生育期0—30 cm土层温度,图2-b表示的是各处理下0—30 cm土层温度有差异的部分。下同

Fig. 2 Variation of soil temperature and significant difference in 0-30 cm soil layer during the whole growth period of sunflower from 2015 to 2017 CK: With no straw interlayer; S3: Straw interlayer with a thickness of 3 cm; S5: Sraw interlayer with a thickness of 5 cm; S7: Straw interlayer with a thickness of 7 cm. The value in the figure is the weighted average temperature of the probe. The same as below Figure 2-a shows the temperature of 0-30 cm soil layer during the whole growth period of sunflower, and Figure 2-b shows the part of temperature difference in 0-30 cm soil layer under different treatments. The same as below
