| Abstract: | The irrigation on the film mulching provided crops with a warm-humid environment and laid a foundation for water-saving and yield-increasing.The effects of different plastic film mulching width and discharge per unit width on the water consumption amount during whole growth period,yield components,yield and WUE of plastic film mulched spring wheat in the Inland Irrigation District of He Xi was studied.The results showed that 125 cm plastic film width and 1.3 L·s-1·m-1 discharge per unit width had the most significant water-saving and yield increasing effects on spring wheat in the region.Thus technique supervises and scientific basis were offered for the popularization and application of irrigation on the film mulching in Hexi region. |
