Abstract:

To explore the tolerances of compact hybrid rice (CHR) and loose hybrid rice (LHR) varieties to nitrogen fertilizer, three split-plot designed experiments were applied with main plot of four rice varieties (Longliangyou 1206, CHR; Y Liangyou 1, CHR; Yixiangyou 2115, LHR; and Fyou 498, LHR), and the sub-plot contained four N application rates (0 kg hm-2, N0; 90 kg hm-2, N90; 150 kg hm-2, N150; and 210 kg hm-2, N210). The results revealed that CHR was more tolerant to high nitrogen than LHR, and when the applied nitrogen was not higher than 150 kg hm-2, the yields of LHR were higher than those of CHR. When the applied nitrogen reached 210 kg hm-2, the single panicle weight advantage of CHR increased to 14.46%, while the effective panicle disadvantage decreased to 12.46%, then the yield of CHR was 1.43% higher than that of LHR. Partial least squares regression analysis showed that peak seedlings, growth rate from elongation to heading stage, leaf area index (LAI) and extinction coefficient (K-value) which characterized the degree of leaf stretching were positive contributions to CHR and LHR. The effective panicle rate at elongation and heading stages contributed negatively to the yield, but had the opposite effect on the agronomic efficiency of nitrogen fertilizer. Except K-value, the other indicators contributed similarly to yield, as did the agronomic efficiency of nitrogen fertilizer. Under N0 and N90, LAI and K-values of CHR were smaller than LHR, and the radiation interception rate was also lower than LHR. When nitrogen applied increased from 150 kg hm-2 to 210 kg hm-2, the K-value of CHR increased significantly, while LHR almost unchanged, resulting in the higher radiation interception rate at heading stage of CHR than LHR, indicating that the leaf stretching of CHR was sensitive to high nitrogen.

Key words: rice, compact hybrid rice, loose hybrid rice, nitrogen application rate, nitrogen tolerance
