| Abstract: | A field experiment is carried out to explore the cotton with drip irrigation under mulch and field irrigation.The results showed that the former can save 46 percent water than the latter,and the seed cotton output of drip irrigation under mulch is 6 percent less than field irrigation and it increases 217 percent more than dry land.Water productivity of drip irrigation under mulch is about 4.0kg per cubic.Water productivity of field irrigation is about 2.2kg per cubic.Water productivity per cubic drip under mulch is 82 percent higher than field irrigation. |
