  1. CK, no crop straw and K fertilizer were applied as the blank control treatment; K150, 150 kg·ha−1 K2O was applied before transplanting the cotton seedlings; and W9000, 9000 kg·ha−1 wheat straw was crushed and incorporated in 010 cm soil before transplanting. Values followed by different letters within the same column are significantly different at P = 0.05. Each value represents the mean of three replications
