Determination of photosynthetic pigments used 80% of acetone extraction method directly and the photosynthetic characteristics of using Li-6400 portable photosynthesis detector. Results showed that Returning the right amount maize straw stem into field was able to significantly restraint this year winter wheat flag leaf Chla degradation, to raise the flag leaf Chla/Chlb in the watery metaphase and late stage, to effectively restraint the photosynthesis rate decrease in the watery stage, to increase the pertinence of photosynthesis rate and pigment compared to others. However returning more maize straw stem into field was able to accelerate the retrogradation of chlorophyll and photosynthesis rate decrease then the yield declined.

结果表明：适量的玉米秸秆还田(9 000 kg/hm^2)可显著抑制接茬冬小麦灌浆中后期旗叶Chla降解，提高小麦灌浆中后期旗叶Chla/Chlb的比值，有效抑制灌浆期旗叶光合速率的下降，与其他处理相比，其光合速率与叶绿素的相关性得到加强；过量的秸秆还田(15 000 kg/hm^2)，加速了光合色素的降解，使得光合速率下降，产量降低；在各处理中，处理Ⅱ(9 000 kg/hm^2)产量最高。
