Different lowercase letters indicate that the difference between different treatments of the same index is significant (\(p<0.05\)), and ** indicates that the difference reached a very significant level (\(p<0.01\)). LSP: light saturation point; LCP: light compensation point; Pmax: the maximum net photosynthetic rate; AQE: apparent quantum yield; Rd: dark respiration rate; R\({}^{2}\): coefficient of determination.

Table 1: Cotton light-response characteristic parameters at different growth periods. During the same growth period, different allocation patterns affected the distribution ratio of the vegetative and reproductive organs. In 2020, the proportion of dry matter distribution in the reproductive organs of each treatment was as follows: CM2 > CM1 > CK > CM. The distribution and accumulation of dry matter in the CK treatment were the largest at the other growth periods.
