| Abstract: |
| Comparative experiments were conducted to investigate the effects of conversation tillage on photosynthesis characteristic, dry matter accumulation and WUE in wheat of purple hilly areas. The results showed that straw mulching and using decomposing agent incresed LAI at later growth stage of wheat, and net photosynthetic rate were incresed by 2.90% and 5.74%; two treatments could control plant height at certain extent and promote dry matter accumulation from heading to maturing stage, and partitioning index of spike was increased by 238.46% and 242.31%; application of straw mulch + decomposing agent increased wheat yield, WUE and rainfall use efficiency by 8.07%, 5.80% and 8.02% respectively. |
