摘　　要：在中国科学院桃源农业生态试验站进行了长期定位试验,以研究在等量化肥氮条件下,NP、NPK、NPK+C(养分循环)等处理对水稻生长发育的影响。结果表明,等量化肥氮条件下配施NPK+C对水稻生长影响最为明显,各项指标均为最高,早稻和晚稻产量分别是CK的2.5倍与1.6倍左右。NP、NPK、NPK+C处理均可显著促进水稻生长发育并提高产量;增施肥料主要通过增加单位面积穗数来提高稻米产量。Based on a long-term fertilization experiment at Taoyuan Station of Agro-Ecology Research, the Chinese Academy of Sciences, the effects of different treatments including NP, NPK, NPK＋C （nutrient cycling）, etc. on paddy soils and the rice growth were studied. The results showed that under the same N condition,the change of soil nutrient content with NPK＋ C was the most obvious. Treated with NP,NPK and NPK＋C,the rice growth and development and the total output could be significantly promoted. By increasing the number of spikes per unit area, adding ~ertilizers could promote the rice yield. All the growth and development indicators were the highest under NPK＋ C treatment, and compared with CK, the production of early rice and late rice was increased by 2.5 times and 1.6 times,respectively.
