Abstract:In order to explore the best tillage method and nitrogen rate of strong gluten wheat in western Shandong Province and to provide a basis for its high -quality and -yielding cultivation technology,the field experiment was conducted to research the effects of three tillage methods (zero tillage,deep tillage and rotary tillage)and four nitrogen treatments (165,225,300,360 kg/hm2 )on Zhouyuan 9369.The results showed that under the three tillage methods,the wheat population in every period increased with the increase of nitro-gen rate,and slowed down when the nitrogen rate reached a certain level.With the same nitrogen rate,the deep tillage treatment showed the largest population.However,the leaf area index (LAI)wasn’t in accord-ance with wheat population with the increase of nitrogen rate.Especially after overwintering,the LAI was in-versely proportional to nitrogen rate.With the same nitrogen rate,the protein content in wheat grain of deep tillage treatment was the highest.Under three cultivation methods,the protein content,wet gluten content, sedimentation value,the development time and stability time all increased with the increase of nitrogen rate.It was proved that the strong gluten wheat had the highest yield under the conditions of deep tillage and 300 kg/hm2 nitrogen fertilizer.
