Abstract: 【OBJECTIVE】The objective was to reveal characteristics of nutrients accumulation and distribution in early and ratoon rice under different cultivation models; 【METHOD】Dry weight and nutrients contents in the rice plants were determined at different developmental stages, using a new combination hybrid rice II Youhang 1 under super high-yield cultivation (SHC) and conventional cultivation(CC) models;【RESULTS】The results showed that the accumulated N, P and K in the plant were 15.06 g/m2, 4.58 g/m2 and 15.8 g/m2 at the fully ripening stage under SHC models, which were 47.2%, 21.2% higher and 9.1% lower than those under CC models respectively. The nutrients partitioned into grain were 50.5%, 47.8% and 25.3%, they were approximately equal to those as mentioned above. The production efficiencies of N, P and K were 75.39 kg/kg, 247.9 kg?kg-1 and 71.9 kg/kg respectively, showing higher use efficiency of P and K. The accumulated N, P and K in ratoon rice plants were 10.9 g/m2, 4.05 g/m2 and 12.9 g/m2respectively at fully ripening stage, which were 38.0%, 30.5% and 78.3% higher than those CC models. The partitioned ratio of nutrients into grain were 51.0%, 68.1% and 15.5%, which was 9.1% lower for N and 7.0% lower for K than that in rice under CC models. The use efficiencies of N, P and K were 75.60 kg/kg, 203.5 kg/kg and 63.9 kg/kg respectively, showing lower use efficiency of N and K for SHC models. The demands for N, P and K in the early season rice in SHC models were 17.9 g/m2, 6.77 g/m2, 34.9 g/m2, which were 54.3%, 35.4% and 73.6% higher than those in CC models respectively, and 9.59 g/m2 N, 3.61 g/m2P, 17.20 g/m2 K were needed in the ratoon rice crop, showing 61.2%,43.8% and 361.1% higher than those in CC models;【CONCLUSION】In a word, a higher nutrients demand, accompanying with more smoothly absorption and translocation of N, P and K which were beneficial to nutrients partition in the plants and enhanced production, but further effort must be made to enhance the utilization efficiency of N and K.
