摘　　要：在山东潮土进行田间试验,研究过磷酸钙和磷酸二铵施用对冬小麦-玉米轮作体系下作物磷吸收和土壤无机磷形态组成的影响。结果表明:施用磷肥处理小麦、玉米产量高于不施磷肥处理,磷肥种类与用量处理之间没有显著差异;过磷酸钙和磷酸二铵两种磷肥处理土壤不同形态无机磷含量之间差异不明显;P2O5 90和150kg/hm2过磷酸钙和磷酸二铵施用效果相当,因此磷肥施用量可以适当减少。The field experiment is conducted in fluvo aquic soil in Shandong. The effects of superphosphate（SP） and diammonium phosphate （DAP） application on phosphorus absorption of crop and soil inorganic phosphorus forms in winter wheat-maize rotation system are studied. The results show that： the yield of wheat and maize of DAP and SP treatment is higher than the treatment without P application. There is no significant difference of crop yield between DAP and SP. Various forms of P contents in soils have no obvious differences between DAP and SP; P2O5 90 and 150 kg/hm^2 DAP and SP has similar effects, so the amount of phosphate fertilizer could be reduced to P2O5 90 kg/hm^2.
