棉花膜下滴灌在新疆已广泛应用,截止2011年底,新疆棉花膜下滴灌面积达到12 333千米2,由于覆膜和灌溉会导致土壤氧气降低,而棉花又是低氧敏感作物,曾有人利用空气注射器将空气加入大豆和棉花根区进行灌溉,结果表明:新鲜大豆产量增加了82%~96%,棉花产量增加了14%~28%,增氧灌溉有利于根区微生物的活动和矿物质的运移,最终导 Cotton drip irrigation has been widely used in Xinjiang, as of the end of 2011, Xinjiang cotton drip irrigation area reached 12,333 km 2, due to the film and irrigation will lead to reduced soil oxygen, and cotton is hypoxia sensitive crops, it was used The air injector added air into the root zone of soybean and cotton for irrigation. The results showed that the yield of fresh soybean increased 82% ~ 96% and that of cotton increased by 14% ~ 28%. Aerobic irrigation was beneficial to the activities and minerals of root zone microbes The migration, the final guide
