以春小麦品种永良15号为材料，研究了全膜覆土穴播对春小麦旗叶光合生理特性和产量的影响。结果表明，全膜覆土穴播提高了春小麦灌浆期旗叶净光合速率（Pn）和叶绿素（SPAD）含量，延长了净光合速率高值持续期（PAD）和叶绿素含量缓降期（RSP）；也提高了灌浆中后期旗叶的蔗糖磷酸合成酶（SPS）活性，在灌浆期能保持相对较高的蔗糖供应能力。经济性状优良，产量较全膜不覆土穴播提高12.4%。

Spring wheat varieties Yongliang 15 as material,the effects of hole sowing mulched with plastic film on photosynthetic characteristics and yield of flag leaves of spring wheat is studied. The result shows that dynamic changes of net photosynthetic rate (Pn)and photosynthetic active duration (PAD)of flag leaves are significantly increased during the grain filling period under the whole plastic-film mulching combined with soil overlying. Moreover,the extended steady phase of chlorophyll content (RSP) and the increased photosynthetic active duration in flag leaf might decelerate the aging of flag leaf,which could significantly increased its photosynthate supplying duration. Compared with the control,both sucrose phosphate synthetase (SPS) activity and sucrose supplying capability of flag leaves in spring wheat are significantly increased during the early and middle grain filling period.
