| Abstract: |
| Through an experiment on water saving technology of pepper under furrow irrigation in ridge culture with
full film-covering combined with water-holding agent in Minqin region during the months of May to Sept. in 2009，the soil moisture diffusion, water consumption and yield effect of pepper were tested under transplanting with water condi-tions. The impacts on soil moisture were analysed in matching application of water-holding agent. The result showed that in Minqin，using technology of transplanting pepper with water under furrow irrigation in ridge culture conditions and matching application of water holding agent would increase pepper production by 19.73%， save water by 30. 79%, and improve water use efficiency by 42.33%. Appropriate use of water holding agent ccould reduce water consumption of crops，and the results were more obvious in using it in the rational range. |
