| Abstract: |
| In the irrigable areas in Hexi oasis of Gansu, study was made on yield, water use efficiency (WUE) and soil fertility in different irrigation and cultivation pattern combinations for malting barely. The results show that the ridge planting with furrow mulching increases the barley yield by 695 kg/hm2 caompared to tra
ditional tillage and the rate of growth is 10.2% when the irrigation amount is 330 mm. Compared with CK, ridge planting with furrow mulching treatment does not reduce the yield at 270 mm irrigation, while it can save water by 60 mm. The water use efficiency increases first and then shows a falling trend when irrigation amount increases from 210～330 mm, the maximum is in 280 mm, and the best is 17.57 kg/(mm·hm2) in ridge planting with furrow mulching. Ridge planting with straw mulching can significantly improve the soil nutrient content. So ridge planting with furrow mulching is the best water-saving cultivation mode for malting barely in the irrigable oasis. |
