In order to explore the adaptability of strong-gluten wheat under different soil types and the differences in yield and quality among varieties, the pot experiments were conducted with three strong-gluten wheat varieties Gaoyou 2018, Shiluan 02-1 and Shiyou 20 as materials in fluvo-aquic soil environment and black soil environment. The changes of flag leaf chlorophyll content, grain weight and nitrogen content of various organs of the strong-gluten wheat varieties from flowering stage to maturity stage under fluvo-aquic soil and black soil were compared. The similarities and differences of stem number per plant, yield and its components, grain protein and component content, and protein yield at maturity stage were compared; Since the flowering period began, the nitrogen content of various plant vegetative organs gradually decreased, while the nitrogen content of grains showed a trend of first decreasing and then increasing. The results showed that the chlorophyll content of wheat in the two soils increased first and then decreased from flowering to 25 days after flowering, and reached the maximum at 5 days after flowering. Compared with the fluvo-aquic soil, the leaf staying green time and grain filling time of wheat were prolonged under the conditions of black soil, and the duration of grain filling gradual increasing period of the three varieties was prolonged by an average of 3.0 days. The stem number per plant, effective spike number and 1 000-grain weight increased by 10.91%, 18.62% and 3.85%, respectively; the number of ineffective spikes decreased by 1.35%; the non-gluten protein content and gluten protein content in grain increased by 0.18% and 1.48%, respectively; and the protein yield increased by 0.51 g·pot-1. In summary, under the conditions of this experiment, black soil significantly promoted wheat tillering, protein content, and increased yield compared with fluvo-aquic soil.
