Biochar Improves Yield by Reducing Saline-Alkaline Stress, Enhancing Filling Rate of Rice in Soda Saline-Alkaline Paddy Fields.

Biochar treatments were not consistent in their effects on rice leaf O 2 − content, which generally showed that rice leaf O 2 − content under B1, B2, and B3 treatments showed an increasing trend in both reproductive stages; the B2 treatment especially differed from the B0 treatment to a significant level in the heading stage ( Figure 3 B); however, the high-biochar treatment (B4) significantly decreased rice O 2 − content ( p < 0.05) under the N225 treatment at the heading stage and the N0 and N225 treatments at the filling stage, with O 2 − content under the treatments ( p < 0.05).

The positive correlations ( p < 0.01) between SuSase, AGPase, StSase, and SBE and the filling parameters were highly significant.
