Experiments were carried out on the experiment farm of Anhui agricultural university with pot culture from 2003 to 2005.Effects of waterlogging at different stages on N

P and K nutrition metabolism were studied applying simulation waterlogging method.The results showed that waterlogging at different stages significantly influenced N and P nutrition absorption content and transportation and distribution ratio and less influenced K nutrition of different cultivars

injury degree of waterlogging at booting stages more than other stages.Waterlogging before booting stage mainly influenced N and P and K nutrition absorption content and less influenced transportation and distribution

waterlogging at filling stages mainly influenced N and P and K nutrition absorption content and N and P nutrition transportation and distribution ratio and less influenced K nutrition transportation and distribution ratio of different organ.So applying rich P and K fertilizer at basal fertilizer and rapidly available N fertilizer form jointing stage to booting stage and KH_2PO_4 at filling stage and it is very important that to culture strong stem and large spike and to reduce waterlogging injury and to increase grains yield of waterlogging wheat.
