摘要
Abstract
Objective]To screen nitrogen management for high yield and superior quality cultivation of wheat Guangmingmai 1.[Method]Effects of nitrogen amounts and ratio of nitrogen on population traits and grain yield were studied.[Result]With the increase of nitrogen content,stem tiller number and grain yield showed a changing trend of up at first and then down .Under the same nitrogen application level,the stem tiller num-ber and stem tillers earing rate under the ratio of 5∶5 treatment were the highest,grain yield was also significantly higher than the treatment of 6∶4、7∶3 and 8∶2.[Conclusion]Under the conditions of this experiment,when the nitrogen amounts was 300 kg/hm2 and the ratio of base N to dressing N was 5∶5,the percentage of internode length below spike was the highest,and the grain yield was also the highest.关键词
