The effects of phosphorus (P) and lime application on yield and biomass and P uptake and utilization of sweet corn were evaluated with a field experiment. Research on the appropriate rate of P application would provide a theoretical basis in improving sweet corn yield and P use efficiency. The field experiment was a split-plot design with main-plot randomly assigned into each of four blocks. The main-plot treatments were four P application rates (0, 60, 120 and 180 kg/hm2, expressed as P0, P60, P120 and P180). The split-plot factors were two lime levels (0 and 750 kg/hm2, expressed as L0 and L1). The responses of sweet corn yield, P uptake, soil available P and P fertilizer utilization efficiency to P fertilizer application and lime application were studied. The yield of sweet corn increased significantly under P120 and P180 treatments without lime by 19.4% and 18.5%, respectively, compared with P0 treatment. Compared to P0, the yield of sweet corn increased significantly by 14.0% under P60 treatment with lime. Under P60 treatment, lime increased the yield of sweet corn significantly by 12.7%. P fertilizer application increased both total biomass and P uptake of sweet corn significantly. After two sweet corn growing seasons, soil available P under P60 treatment had no significant difference comparing with the original value. Soil available P basically maintained a balance under P60 treatment. Soil available P in P120 and P180 treatments increased by 103.8% and 228.4%, respectively, compared with the original value, and soil available P increased obviously in 0-20 cm soil layer. The fresh ear yield per P uptake and P physiological efficiency decreased significantly with P application rates. Also, the P use efficiency of sweet corn declined with P application rates. P agronomic efficiency, recovery efficiency, and partial factor productivity increased significantly under lime treatments with P60 treatment, compared with no-lime treatments. Together, these results indicated that the application of 60 kg/hm2 P fertilizer combined with lime can be an efficient way to obtain high yield and P utilization efficiency of sweet corn and maintain the balance of soil available P.

采用田间肥料定位试验研究了磷肥用量与石灰配合施用对甜玉米产量、生物量、磷素累积及磷肥利用效率的影响,旨在为甜玉米高产及磷素高效利用途径提供理论依据。试验采用裂区设计,主区为磷肥用量,设置P0(0 kg/hm2)、P60(60 kg/hm2)、P120(120 kg/hm2)、P180(180 kg/hm2)4个磷肥水平;副区为石灰处理,设置L0(0 kg/hm2)和L1(750 kg/hm2)2个石灰水平,研究甜玉米鲜食期产量、磷素累积、土壤速效磷及磷肥利用效率对磷肥用量和石灰施用的响应。结果表明,L0处理下,与P0处理相比,P120和P180处理甜玉米鲜穗产量均显著提高,分别增产19.4%和18.5%,P0与P60处理间差异不显著;L1处理下,P60处理较P0处理甜玉米鲜穗产量显著提高,增产14.0%,而P60、P120和P180处理间差异不显著。且在P60处理下,L1处理较L0处理甜玉米鲜穗产量显著提高,增产12.7%。与P0处理相比,施磷处理甜玉米总生物量和磷素累积量显著提高。连续种植2季甜玉米后,P60处理的土壤速效磷含量较初始值无显著差异,土壤速效磷含量基本维持平衡;P120和P180处理的土壤速效磷含量较初始值分别增加了103.8%和228.4%,土壤速效磷在0~20 cm土层积累明显。施磷显著降低1 kg磷素生产鲜穗产量和磷素生理效率,且随施磷量的增加磷肥利用率显著下降。在P60处理下,与L0处理相比,L1处理甜玉米磷肥农学效率、磷肥利用率和磷肥偏生产力均显著提高。因此,磷肥用量60 kg/hm2配合石灰施用不仅能满足甜玉米高产需求,同时可以达到较好的磷肥利用效率和维持土壤速效磷平衡,可作为该地区甜玉米高产增效与环境友好的磷肥管理措施。

采用田间肥料定位试验研究了磷肥用量与石灰配合施用对甜玉米产量、生物量、磷素累积及磷肥利用效率的影响,旨在为甜玉米高产及磷素高效利用途径提供理论依据。试验采用裂区设计,主区为磷肥用量,设置P0(0 kg/hm2)、P60(60 kg/hm2)、P120(120 kg/hm2)、P180(180 kg/hm2)4个磷肥水平;副区为石灰处理,设置L0(0 kg/hm2)和L1(750 kg/hm2)2个石灰水平,研究甜玉米鲜食期产量、磷素累积、土壤速效磷及磷肥利用效率对磷肥用量和石灰施用的响应。结果表明,L0处理下,与P0处理相比,P120和P180处理甜玉米鲜穗产量均显著提高,分别增产19.4%和18.5%,P0与P60处理间差异不显著;L1处理下,P60处理较P0处理甜玉米鲜穗产量显著提高,增产14.0%,而P60、P120和P180处理间差异不显著。且在P60处理下,L1处理较L0处理甜玉米鲜穗产量显著提高,增产12.7%。与P0处理相比,施磷处理甜玉米总生物量和磷素累积量显著提高。连续种植2季甜玉米后,P60处理的土壤速效磷含量较初始值无显著差异,土壤速效磷含量基本维持平衡;P120和P180处理的土壤速效磷含量较初始值分别增加了103.8%和228.4%,土壤速效磷在0~20 cm土层积累明显。施磷显著降低1 kg磷素生产鲜穗产量和磷素生理效率,且随施磷量的增加磷肥利用率显著下降。在P60处理下,与L0处理相比,L1处理甜玉米磷肥农学效率、磷肥利用率和磷肥偏生产力均显著提高。因此,磷肥用量60 kg/hm2配合石灰施用不仅能满足甜玉米高产需求,同时可以达到较好的磷肥利用效率和维持土壤速效磷平衡,可作为该地区甜玉米高产增效与环境友好的磷肥管理措施。

The effects of phosphorus (P) and lime application on yield and biomass and P uptake and utilization of sweet corn were evaluated with a field experiment. Research on the appropriate rate of P application would provide a theoretical basis in improving sweet corn yield and P use efficiency. The field experiment was a split-plot design with main-plot randomly assigned into each of four blocks. The main-plot treatments were four P application rates (0, 60, 120 and 180 kg/hm2, expressed as P0, P60, P120 and P180). The split-plot factors were two lime levels (0 and 750 kg/hm2, expressed as L0 and L1). The responses of sweet corn yield, P uptake, soil available P and P fertilizer utilization efficiency to P fertilizer application and lime application were studied. The yield of sweet corn increased significantly under P120 and P180 treatments without lime by 19.4% and 18.5%, respectively, compared with P0 treatment. Compared to P0, the yield of sweet corn increased significantly by 14.0% under P60 treatment with lime. Under P60 treatment, lime increased the yield of sweet corn significantly by 12.7%. P fertilizer application increased both total biomass and P uptake of sweet corn significantly. After two sweet corn growing seasons, soil available P under P60 treatment had no significant difference comparing with the original value. Soil available P basically maintained a balance under P60 treatment. Soil available P in P120 and P180 treatments increased by 103.8% and 228.4%, respectively, compared with the original value, and soil available P increased obviously in 0-20 cm soil layer. The fresh ear yield per P uptake and P physiological efficiency decreased significantly with P application rates. Also, the P use efficiency of sweet corn declined with P application rates. P agronomic efficiency, recovery efficiency, and partial factor productivity increased significantly under lime treatments with P60 treatment, compared with no-lime treatments. Together, these results indicated that the application of 60 kg/hm2 P fertilizer combined with lime can be an efficient way to obtain high yield and P utilization efficiency of sweet corn and maintain the balance of soil available P.
