图4 不同物料还田对夏玉米光合色素的影响 CK: 无物料还田; FS: 蚕豆秸秆还田; RS: 油菜秸秆; PM: 猪粪还田。误差线为标准误。不同小写字母代表处理间差异显著(P < 0.05)。(a)为叶绿素a; (b)为叶绿素b; (c)为总叶绿素; (d)为类胡萝卜素。6 leaf为六叶期; Silking为吐丝期; 20 d after silking为吐丝期后20 d。

Fig. 4 Effects of different organic materials returned on photosynthetic pigments of summer maize CK: no material; FS: faba bean straw; RS: rape straw; PM: pig manure returned to the field. Error bars are standard errors. Different lowercase letters represent significant difference in treatments at P < 0.05. (a) is chlorophyll a; (b) is chlorophyll b; (c) is total chlorophyll content; (d) is carotenoid. 6 leaf is six leaf stage; silking is silking; 20 d after silking is 20 d after silking.
