Effects of residue incorporation and K fertilization on soil β-glucosidase activity (p-nitrophenol g− 1·h− 1). Control, neither crop residue nor K fertilizer; W1C0, 0.9 t·ha− 1 wheat straw incorporation alone, W0C1, 0.7 t·ha− 1 cotton straw incorporation alone; W1C1, 0.9 t·ha− 1 wheat straw incorporation + 0.7 t·ha− 1 cotton straw incorporation; K150, 150 kg·ha− 1of K2O; K300, 300 kg·ha− 1 of K2O. F values were given for SS, seedling stage; FS, flowering stage; BS, boll-setting stage and BOS, boll-opening stage. ** means P < 0.01; * means P < 0.05 and ns indicates P ≥ 0.05
