Abstract

Abstract:

In order to explore the effects of combinations of sowing date and nitrogen rate on yield components and nitrogen utilization of high-quality rice variety Nanjing 9108, three sowing dates were set as May 23^rd (B1), June 2^nd (B2), and June 12^th (B3), four nitrogen application rates were set as 0 (N0), 180 kg·hm^-2 (N1), 270 kg·hm^-2 (N2), and 360 kg·hm^-2 (N3) in the field experiment. It was shown that the 1 000-grain weight and yield of rice increased with the delay of sowing date, and the number of panicles increased with the increasing nitrogen application rate. The nitrogen distribution ratio of grains in the three sowing dates all reached the highest under N1 treatment. With the delay of the sowing date, the nitrogen partial productivity and nitrogen use efficiency in grain of rice increased, and the agronomic nitrogen use efficiency and the nitrogen physiological efficiency first decreased and then increased. Under the same sowing date, the nitrogen partial productivity, agronomic nitrogen use efficiency, nitrogen uptake and utilization efficiency and nitrogen use efficiency in grain of rice all showed a downward trend with the increasing nitrogen rate. Under the experiment condition, delaying the sowing date with appropriate nitrogen rate were conducive to obtain high yield. Considering the rice yield and nitrogen utilization, B2N2 or B3N2 treatments were suitable choices.

Key words: rice, sowing date, nitrogen application rate, yield, nitrogen utilization
