Fig. 2 Dynamic change of soil water storage in 0-200 cm layer under different treatments PP: plastic-covered ridges and plastic-covered furrows; PS: plastic-covered ridges and straw-covered furrows; PL: plastic-covered ridges and liquid-covered furrows; PF: plastic-covered ridges and bast fiber-covered furrows; PB: plastic-covered ridges and biodegradable-covered furrows; PN: plastic-covered ridges and no-covered furrows; CK: flat plant without mulching. Different lowercase letters above the bars indicate significant difference among the treatments at P < 0.05.
