| 摘 要： | 通过两年田间试验,研究覆膜滴灌等磷量投入条件下,不同施用时期及比例(P1,100%基肥;P2,40%基肥+60%拔节肥;P3,40%基肥+40%拔节肥+20%大喇叭口肥;P4,40%基肥+20%拔节肥+20%大喇叭口肥+20%开花肥)对玉米产量、物质生产与磷素吸收利用的影响。结果表明,分次施磷处理(P2、P3、P4)玉米产量均高于P1处理,P4处理玉米产量与P1处理差异达显著水平(P0.05)。施磷显著提高玉米吐丝期至成熟期干物质量和磷素吸收量,吐丝期干物质量与磷素吸收量以P1处理最高,灌浆期至成熟期干物质量与磷素吸收量以P4处理最高。

| Abstract: | A field experiment was conducted to investigate the effects of different P application periods and proportions on maize yield, matter production, P absorption and utilization among the same amounts of P fertilizer under mulched drip irrigation in 2014-2015. The treatments included P1(100% basal fertilizer), P2(40% basal fertilizer + 60% jointing fertilizer), P3(40% basal fertilizer + 40% jointing fertilizer + 20% belling fertilizer) and P4(40% basal fertilizer + 20% jointing fertilizer + 20% belling fertilizer + 20% flowering fertilizer). The results showed that maize yields of split P application treatments(P2, P3 and P4) were better than that of P1 treatment, respectively. The yield of P4 treatment was significantly higher than that of P1 treatment(P<0.05). P fertilizer application could improve the amounts of dry matter and P absorption from silking stage to maturing stage significantly, in which P1 treatment arrived at the highest at silking stage, and P4 treatment was the highest from filling stage to maturing stage. Compared with P1 treatment, split P application treatments(P2, P3 and P4) reduced P translocation amount, its rate and contribution rate of translocation P to kernels before silking stage of maize. Split P application improved the contribution rate of accumulation P to kernels after silking stage significantly, and P4 treatment reached the highest value. Compared with P1 treatment, P recovery efficiency, agronomic efficiency and partial factor productivity were increased under split P application treatments(P2, P3 and P4), and which of P4 treatment was the highest value. |
