全膜覆土穴播对春小麦光合及产量的影响
Effects of Hole Sowing Mulched with Plastic Film on Photosynthetic and Yield of Spring Wheat
摘要
Abstract
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.关键词
