摘要：

针对土默川平原玉米生产体系磷肥利用效率低，存在面源污染的风险，本研究开展了黄腐酸（FA）配施磷肥的研究，通过测定玉米产量、植株各器官干物质累积量、磷素吸收量，计算玉米的磷肥利用效率，明确黄腐酸对玉米磷素吸收及产量的影响，确定该地区适宜的黄腐酸用量。结果表明，（1）适宜的磷肥配施黄腐酸（P1+FA3，96 kg/hm2 P2O5配施450 kg/hm2黄腐酸）可显著提高玉米的产量，增产7.49%~27.96%。（2）P1+FA3处理可以提高玉米地上部各器官的生物量，茎的生物量比其他处理增加了18.85%~35.26%，叶的生物量比其他处理增加了13.46%~23.64%，籽粒的生物量比其他处理增加了9.68%~27.41%。（3）P1+FA3处理可显著提高玉米的磷肥吸收利用率、磷肥农学效率和磷肥偏生产力。综上，对于土默川平原玉米生产体系，在适宜的磷肥施用下，配施450 kg/hm2的黄腐酸可实现玉米产量和磷肥利用效率的协同提升。

Abstract:

In light of the low phosphorus fertilizer utilization efficiency and the potential risk of non-point source pollution in the corn production system of the Tumochuan Plain, this study investigated the effects of combined application of fulvic acid and phosphorus fertilizer. Corn yield, dry matter accumulation in various plant organs, and phosphorus uptake were measured to calculate phosphorus fertilizer utilization efficiency. The effects of fulvic acid on phosphorus absorption and corn yield were analyzed, and an appropriate application rate of fulvic acid for the region was determined. The results indicated that (1) the appropriate application of 96 kg/hm2 P2O5 combined with 450 kg/hm2 fulvic acid (P1+FA3) could significantly enhance corn yield by 7.49% to 27.96%. (2) The P1+FA3 treatment promoted the biomass accumulation of various above-ground organs of corn. Specifically, stem biomass increased by 18.85% to 35.26%, leaf biomass by 13.46% to 23.64%, and grain biomass by 9.68% to 27.41% compared to other treatments. (3) The P1+FA3 treatment significantly improved the absorption and utilization efficiency of phosphorus fertilizer, enhanced agronomic efficiency of phosphorus fertilizer and partial productivity of phosphorus in corn. In conclusion, within the corn production system of the Tumochuan Plain, the combined application of 450 kg/hm2 fulvic acid under an appropriate phosphorus fertilizer rate could synergistically improve both corn yield and phosphorus use efficiency.
