【Objective】The effect of different base-topdressing ratios of phosphate fertilizer on nutrient absorption and yield of drip irrigation corn was studied through field plot experiments, which provided a experimental basis for efficient phosphorus application technology of drip irrigation maize. 【Method】The experiment has a total of 5 treatments. P0(no phosphate fertilizer), Pb100(base: topdressing at 1:0), Pb50(base: topdressing at 1:1), Pb25(base: topdressing at 1:3), Pb0(base: topdressing at 0:1). 【Result】Under the same phosphorus application, base-topdressing ratios of phosphate fertilizer have different effects on P uptake amount, yield and phosphate recovery rate of drip-irrigated maize. P applied with 25% base fertilizer and 75% topdressing performance best P recovery rate and corn grain yield. The P absorption in the middle and late growth stages of maize was higher than the other four treatments. Yield increased by 18.05%, and phosphate recovery rate was 23.90%. The research found that the N and P uptake peak were at middle and late stages of maize growth (spinning to filling stage). And the absorption of phosphorus and nitrogen by maize showed significant positive correlation during silking and filling stages. It showed that increasing the proportion of P applied in the later stage is conducive to driving N absorption by mazie. 【Conclusion】Under the condition of drip irrigation, 25% phosphate base and 75% topdressing is the best P application strategies, it guarantee the P supply of the maize during the various growth periods, promote the growth of maize and the formation of yield.
