摘要: Little is known about the interactive effects between biochar application and phosphorus (P) fertilization on plant growth and P uptake. For this purpose, five wheat straw biochars (produced at 25 degrees C, 300 degrees C, 400 degrees C, 500 degrees C and 600 degrees C for 4 h) with equal P (36 mg kg(-1)) amount, with and without additional P fertilization (100 mg kg(-1)) were applied in a pot experiment to investigate the growth of Suaeda salsa and their uptake of P from biochar and P fertilization amended saline sodic soil. Soil P fractions, dry matter yield, and plant P concentrations were determined after harvesting 90 days. Our results confirmed that relatively lower pyrolysis temperature (<400 degrees C) biochar retained P availability and increased plant growth. The plant P concentration was significantly correlated with NaHCO3-P-i (P < 0.05), and NaOH-P-i (P < 0.1) during early incubation time (4 days) for biochar amended soil. As revealed by statistical analysis, a significant (P < 0.05) negative (antagonistic) interaction occurred between biochar and P fertilization on the biomass production and plant P concentration. For plant biomass, the effects size of biochar (B), P, and their interaction followed the order of B x P (0.819) > B (0.569) approximate to P (0.568) based on the partial Eta squared values whereas the order changed as P (0.782) > B (0.562) > B x P (0.515) for plant P concentration. When biochar and P fertilization applied together, phosphate precipitation/sorption reaction occurred in saline sodic soil which explained the decreased plant P availability and plant yield in saline sodic soil. The negative interaction effects between biochar and P fertilization indicated limited utility value of biochar application in saline sodic soil. (C) 2016 Elsevier B.V. All rights reserved.
