Abstract

In order to explore the effects of different reducing fertilizer application modes on nutrient use efficiency of wheat in rice-wheat cropping system to provide theoretical basis for achieving high efficient application of chemical fertilizer and its zero increase in China, this paper carried out 3 years field positioning experiment of rice-wheat cropping system. The experiment set 6 treatments including no fertilizer(T1), conventional chemical fertilization (T2), combined application of organic; manure and chemical fertilizer (T3), reducing 20% Chemical fertilizer plus increasing nitrogen fertilizer synergist application (T4), reducing 20% chemical phosphorus fertilizer long with phosphorus activator application (T5), and reducing 20% chemical nitrogen fertilizer and 20% Chemical phosphorus fertilizer along with nitrogen fertilizer synergist plus phosphorus activator application (T6). The results showed that T4 treatment was beneficial to enhance the nitrogen absorption capacity of wheat, improve the nitrogen absorption efficiency, enhance the nitrogen use efficiency, improve the potassium use efficiency; T5 treatment could significantly increase the total phosphorus uptake, phosphorus uptake efficiency, partial productivity and absorption efficiency of wheat. T6 treatment could significantly improve the nitrogen absorption capacity, phosphorus partial productivity and potassium use efficiency of wheat. T3 treatment had no significant effect on the absorption and utilization of nitrogen and phosphorus in wheat, and significantly reduced the partial productivity of potassium in wheat. In conclusion, theT6 treatment was beneficial to coordinate nutrient uptake and stabilize wheat yield. It could be a preference pattern for reducing fertilizer application and increasing efficiency in rice-wheat cropping system at the Middle and Lower Reaches of the Yangtze River and with similar ecological conditions.
