Abstract: The study aims to improve the cultivation technology system of strong gluten wheat. The strong gluten wheat‘Zhou yuan9369’was used as test material, the effects of nitrogen application amount, topdressing proportion, topdressing time on yield and quality of strong gluten wheat were studied. The results showed that the yield and crude protein content increased with the increasing of nitrogen application amount within a certain limit. The yield and nitrogen application amount showed quadratic curve relationship, and 300 kg/hm2 was the best nitrogen application amount in this experiment. The yield increased firstly with the decreasing of topdressing proportion, and then decreased. The crude protein content decreased with the decreasing of topdressing proportion, 3:7 was the most appropriate topdressing proportion in this experiment. Different topdressing time had different effects on grain yield and quality of strong gluten wheat, topdressing at jointing stage was the best in this experiment. The optimal plan of this experiment was nitrogen application amount 300 kg/hm2, topdressing proportion 3:7, and topdressing at jointing stage.
