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。

摘  要：
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 fertilizers 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.
