| Abstract: |
| In order to choose a water-saving and water conservation pattern suitable for Weibei apple orchard, the trees of Shannxi Fuji 6 were used as research materials to study the effects of different types of irrigation on soil water dynamic and soil water storage within 0～1 m soil layer. The results showed that: (1) As for soil water content, drip irrigation under mulch was the highest among 5 treatments, then irrigation under mulch and drip irrigation, the furrow irrigation third, while they were all higher then no-irrigation. (2) After an irrigation on J
une 15, the soil water content decreased with the increase of days after irrigation, while the fluctuation got smaller in deeper soil layer; the fluctuation of soil water in drip irrigation under mulch and furrow irrigation under mulch was smaller then that in drip irrigation and furrow irrigation. (3) The water content in drip irrigation under mulch was higher than in drip irrigation, while that in furrow irrigation under mulch was higher than in furrow irrigation. (4) The apple yield and WUE in drip irrigation under mulch were higher than in other methods of irrigation. The apple yield and WUE in drip irrigation under mulch were higher than in drip irrigation, and those in furrow irrigation under mulch were higher than in furrow irrigation. In a ward, irrigation under mulch could improve soil water content and WUE, and drip irrigation under mulch was a suitable water-saving and water conservation pattern for Weibei apple orchard, which could not only save water, but also maintain higher soil water content. |
