Drip irrigation fertilization (DF) technology is a comprehensive management measure for sustainable development of modern agriculture. Its merits include economy water and fertilization, prevent soil and environment pollution, etc.Therefore,this paper in the drip irrigation under the condition of fertilization, through the effects of different level of fertilizer field experiment, the main research drip irrigation fertilization for Sweet-waxy maize yield quality and nutrient absorption. The results showed as follow:(1)Before silking stage, drip irrigation fertilization (reduce30%and40%) Reduce the dry matter accumulation and NPK accumulation in Sweet-waxy Maize have significant reducer than Conventional fertilization; There are not significant differences in dry matter accumulation and NPK accumulation at maturation stage.(2) There are not significant effect in nitrogen, phosphorus, potassium PUE and NHI in drip irrigation fertilization (reduce30%and40%).It increase the PFP, AE and RE of nitrogen, phosphorus, potassium.(3) Compared to CK1,DF100-DF50treatments reduce Available P and Available K content.But there are not effect on alkali solution nitrogen.(4) Reduction Drip irrigation fertilization (reduce30%and40%) has not obvious influence on ear length and plant height in waxy maize.Ear diameter and stem diameter are increased, bald pointed length is decreased Compared to CK1.DF100-DF50treatments have no obvious influence in corn100-kernel weigh、harvest index、Soluble sugar、Protein and Residue ratio. The corn yield and fertilizer productivity are increased。Therefore,70%and60%of conventional fertilizer combined with irrigation seems to be a good practice for production of sweet-waxy maize under certain soil fertility condition.
