摘　　要：研究了磷肥、磷肥和有机肥配合在油菜和大白菜上的产量(生物量)效应、土壤中磷素的积累状况及磷肥对蔬菜全磷量的影响。结果表明,适量施用磷肥和有机肥均显著增加油菜和大白菜的产量。随磷肥用量的增加,油菜和大白菜产量按报酬递减率增加,大量施用磷肥时导致油菜和大白菜对磷素的奢侈吸收,随着磷肥用量的增加油菜和大白菜全P量及土壤Olsen-P均显著增加,而油菜和大白菜产量无显著变化。The yield response of vegetable to phosphorus fertilizer were studied. The status of accumulating phosphorus and the content of phosphorus in vegetable were also investigated in this paper. Results showed that the yield (biomass) of vegetable was increased obviously by applying phosphorus and manure rationally. Phosphorus was absorbed luxuriously accompanying with applying high level phosphorus fertilizer. The content of total P in vegetable and Olsen-P in soil were enhanced gradually adding phosphorus fertilizer, but the yield(biomass) of vegetable was not changed significantly.
