SFM:夏闲期覆盖;YM:周年覆盖;RM+FS:垄覆沟播;PM:全膜穴播;SM:秸秆覆盖
图中误差线表示标准差。不同大写字母表示不同覆盖时期间差异显著（P<0.05）;小写字母表示同一覆盖时期不同覆盖方式之间的差异显著（P<0.05）。下同
Fig. 2. Winter wheat yield under different mulching periods and mulching practices
SFM: Mulching during the summer fallow; YM: The year-round mulching; RM+FS: Ridge-furrow plastic mulching; PM: Whole field plastic mulching; SM: straw mulching
Error bars indicate standard error. Different capital letters mean significant differences between different mulching periods (P<0.05); different lowercase letters mean significant differences between different mulching practices in the same mulching period (P<0.05). The same as below
