Based on 'forage-grain ratoon rice', the planting pattern of high grain yield of ratoon crop (RC), supplemented by fodder, can be regulated by cutting time and stubble height. In 2021 and 2022, using Xiangliangyou 900 as the experimental material, field trials were conducted to investigate the differences in yield formation of regenerated tillers from different nodal positions under varying cutting times (10 d and 30 d after heading) and stubble heights (10 cm and 30 cm). The results showed that,the average grain yield of T10 was 80.48% higher than that of T30, while the average grain yield of...
