Abstract:

The field experiment was conducted to study the Effect of phosphorus optimized management method on Grain Quality of Winter Wheat in order to supply theoretic basis for nutrient optimized management with the aim of high yield, excellent grain quality, high efficiency of nutrient resource and friendly environment. The main results were as follows: There was no significant differences in the winter wheat grain yield among different P rates. No significant differences of winter wheat grain gross protein and gluten contents was also found between optimized P rate（39 kg hm-2 P）and higher P rate（79 kg hm-2 P）, Phosphorus optimized management method with the aim of high yield, high efficiency of nutrient resource and friendly environment effect got excellent grain quality of winter wheat.
