چکیده انگلیسی
Although the root/mycorrhizal processes determine phosphorus (P) uptake by crops and P fertilizer use efficiency, knowledge of the plasticity of cotton root/mycorrhizal processes in response to changes in soil P content is lacking. A field experiment was conducted in 2015 and 2016 to investigate the effects of P fertilizer treatments (0, 75, 150, and 300 kg P2O5 haâ1) on root/mycorrhizal processes and P uptake by cotton plants. The main aim was to explore the possibility of achieving high P fertilizer use efficiency and high yield simultaneously by optimization of P fertilizer application. A low P application rate (75 kg P2O5 haâ1) not only increased root length and hyphal density simultaneously, but also enhanced the spatial distribution of cotton roots in the soil, thereby also increasing the apparent phosphorus recovery (APR). However, P uptake and cotton yield were highest under treatment with 150 kg P2O5 haâ1. Thus, it is difficult to maximize APR and cotton yield simultaneously. If the production target is to obtain a relatively high yield (80-90% of the highest potential yield), then root/mycorrhizal efficiency in P acquisition can be maximized through optimization of the soil available P content. The optimum soil available P content observed in this study was 15-20 mg kgâ1.
