图1 不同土壤耕作方式对水稻叶片SPAD值的影响 CT: 双季水稻翻耕+秸秆还田; RT: 双季水稻旋耕+秸秆还田; NT: 双季水稻免耕+秸秆还田; RTO: 双季水稻旋耕+秸秆不还田。SS: 苗期; TS: 分蘖期; BS: 孕穗期; HS: 齐穗期; MS: 成熟期。标明不同小写字母的柱值在不同处理之间差异达0.05显著水平。

Fig. 1 Effects of different soil tillage treatments on SPAD of rice leaves CT: conventional tillage with residue incorporation; RT: rotary tillage with residue incorporation; NT: no tillage with residue retention; RTO: rotary tillage with residue removed. SS: seedling stage; TS: tillering stage; BS: booting stage; HS: heading stage; MS: maturity stage. Bars superscripted by different letters are significantly different at the 0.05 probability level.
