| Abstract: | Film mulch can effectively meliorate the root entironrnent of crop and decrease ground roughness and evaporation. Based on the conditions of rainfall, evaporation and crop cultivation in different regions, this paper put forward that the suitable irrigation method in north region of the Great Wall wind and sand line, which is high evaporation and little rainfall region, included drip irrigation under film and film hole irrigation with flat film mulch et al, while the film irrigation method suitable to strip cultivation crops in south region of the Great Wall wind and sand line, which is middling evaporation and rainfall region, and suitable for planting wheat, included film slot irrigation with film mulch on the ridge, film hole irrigation and film hole irrigation with flat film mulch et al. |
