The grain yield and quality of waxy wheat variety Huanuo 1 under different nitrogen application rate and plant density were studied.The results showed that the grain yield increased and the grain coarse protein content decreased significantly,with the number of basic seedlings increased from 1.2million to 2.4 million per hm2.While with the number of basic seedlings increased from 2.4 million to 3.0 million per hm2,the grain yield increased with no obvious variation,the flour dough development time was shortened and the farinogram parameters value decreased obviously.The grain yield,the content of grain coarse protein and wet gluten and the farinogram parameters value increased simultaneously,with nitrogen application rate improved from 75 kg/hm2 to 225 kg/hm2.However,with nitrogen application rate increased to 300 kg/hm2 ,the grain yield and the farinogram parameters value reduced,the content of grain coarse protein and wet gluten improved slightly.Under this experimental condition,2.4 million basic seedlings per hm2 and 225 kg/hm2 nitrogen application rate were the optimal combination for obtaining higher grain yield and better quality of waxy wheat variety Huanuo 1.
