Abstract: Under whole quantity of straw returning condition, this study was to research the appropriate balanced fertilization technology using the positioning experiments .The different fertilizers logistics have an effect on yield under the condition of wheat-corn continuous cropping and whole quantity of straw returning. The results indicated that different fertilizer treatments have extremely significant on wheat yields and other factors but ears of K Fertilizer. Straw returning of corn under one year have no significance on wheat yields and production factors but weight of 1000 grains, with the N fertilizer application increasing, the tread of the weight of 1000 grains descended. The high weight of 1000 grains was N24P12K12 with 41.5 g. Straw returning and N interactions have no effect on yields and other yields of factors. Straw returning and P interactions have a significant effect on wheat grain number, and have an extremely significant effect on wheat grain yields and other production factors. Straw returning and K interactions have significant effect on wheat grain number and grain number but other factors. The high yield of different fertilizers was N30P12K12, N36P18K12 and N36P12K12, with 8572.5 kg/hm2, 9028.5 kg/hm2 and 8500.5 kg/hm2.
