图1 不同地膜覆盖模式示意图 玉米生长在宽窄行垄沟结构的沟中。A: FM, 宽(80 cm)窄(40 cm)行垄沟全膜覆盖; B: NM, 宽(80 cm)窄(40 cm)行垄沟无覆盖。

Fig. 1 Schematic diagram of the different plastic film mulching modes in the study The maize was grown in the furrows of ridge-furrow construction with wide - narrow rows. A: FM, ridge-furrow construction with alternating wide (80 cm) and narrow (40 cm) ridges and full plastic film mulching; B: NM, ridge-furrow construction with alternating wide (80 cm) and narrow (40 cm) ridges and no mulching.
