Table 2 SPAD values of rice leaves under different cultivation modes.

From: Film mulching combined with chemical fertilizer increased rice yield by promoting the accumulation of photosynthetic substances in the vegetative growth stage

  1. Note: NMF0:no mulching, organic fertilizer; MF0: mulching, organic fertilizer; NMF1: no mulching, chemical fertilizer; MF1: mulching, chemical fertilizer. The data in the table are mean standard deviation, and different lowercase letters in the same column indicate that the difference between different treatments of the same variety has reached a significant level (P < 0.05, Duncan’s method).
