Abstract: After several years of study, the authors have proposed: (1) The concept, index and suitable model of the superior tiller group of super-high yield wheat; (2) Kinetic index of nitrogen cumulation in super-high yield wheat and high efficient fertilization strategy; (3) Population structure and quality index of super-high yield wheat; (4) Soil basic nutrition index required by super-high yield wheat cultivation and optimized fertilization technique index; (5) The super-high yield cultivation technique with the superior tiller as the core part, which includes three good points, two promotion methods, one control treatment and the moderate management. The three good points mean using high quality super-high yield varieties, properly using superior tiller group and optimizing population kinetic structure and population quality. The two promotion methods mean promoting the strengthening of seedling before winter and promoting more and bigger ears and heavier grains,to get high yeild and high quality. The one control treatment means controlling watering and fertilization. The moderate management means strengthening seedling in late phase and preventing immature decline.
