Abstract:

Phosphorus fertilizer application depths are extremely important for increasing phosphorus uptake and utilization efficiencies. In the present study, root distribution, biomass, grain yield, phosphorus uptake and utilization efficiencies were determined in field experiment and soil column experiment, with five treatments including CK (no P applied), P5 (phosphorus application depth was 5 cm), P10 (phosphorus application depth was 10 cm), P15 (phosphorus application depth was 15 cm), and P20 (phosphorus application depth was 20 cm). Phosphorus fertilizer application depths significantly affected root dry weight and root length of summer maize with a trend of P15>P10>P20>P5>CK. Compared with P5 treatment, averaged grain yield of P15 treatment increased by 23.1% in two years, averaged root dry weight and total root length increased by 13.1% and 22.9% in two years. Both P15 and P20 treatments increased the proportion of root dry weight and root length in the soil layer below -20 cm. The proportion of root dry weight of P15 and P20 treatments reached 35.4% and 36.4%, and the proportion of root length reached 58.7% and 59.3% in soil column experiments; the proportion of root dry weight both reached 19.0% and the proportion of root length reached 39.8% and 39.9% in field experiment, respectively. The optimization of root distribution promoted the accumulation and transport of phosphorus in plants. Compared with P5 treatment, P10, P15, and P20 treatments increased the averaged phosphorus accumulation in two years by 10.6%, 25.2%, and 14.7%, the average phosphorus transport amount in two years by 46.9%, 76.6%, and 57.6%, and the grain yield by 12.9%, 23.1%, and 10.6%, respectively. Compared with P5 treatment, P15 treatment increased the averaged P partial factor productivity, P agronomic efficiency and P apparent utilization efficiency by 19.1 kg kg -1, 19.1 kg kg -1, and 25.2% in two years, respectively. In summary, deep fertilization of phosphorus could increase the distribution of root in deep soil layers, improve the absorption and utilization efficiencies of phosphorus in plants, and significantly improve the grain yield of summer maize. Under the condition of this study, the suitable P fertilizer application depth was 15 cm from the soil surface.

Key words: summer maize, phosphorus application depth, root, yield, phosphorus utilization efficiency
