图6 玉米叶片的代谢网络变化情况 红色圆代表在地膜覆盖处理下总体上调的物质, 绿色圆代表在地膜覆盖处理下总体下调的物质。8个不同的色块从左到右依次代表FMZL、FMZH、FMXL、FMXH、NMZL、NMZH、NMXL、NMXH, 处理同图2。其中绿色色块代表较低的含量, 红色色块代表较高的含量。

Fig. 6 Changes in the metabolic network of maize leaves Red circles represent substances that are generally up-regulated under plastic film mulching treatment, and green circles represent substances that are generally down-regulated under plastic film mulching treatment. Eight different color blocks from left to right represent FMZL, FMZH, FMXL, FMXH, NMZL, NMZH, NMXL, and NMXH, respectively. Treatments are the same as those given in Fig. 2. Among them, green block represents lower expression abundance, and red represents higher expression abundance.
