图1 不同温度播种棉花播前和播后气温及膜下土壤温度的变化 图中从横坐标延伸的虚线代表不同播种日期（分别为2016年4-8、4-16、4-22,2017年4-8、4-12、4-21、4-29）。MST为土壤平均温度,MDT为平均温度,HT为最高温度,LT为最低温度

Fig. 1 Changes of air temperature and soil temperature under mulching film before and after different sowing dates Dot lines in the figure represent the onset time of different sowing dates (4-8, 4-12, 4-21, 4-29 in 2016, 4-8, 4-16, 4-22 in 2017, respectively). MST: Mean soil temperature; MDT: Mean daily temperature; HT: The high temperature; LT: The low temperature
