Abstract:: The experiment was conduced to study the effect of unary or binary coverage of three micro-catchment patterns in comparison with the traditional cropping pattern.The results indicated that T₂(ridge and ditch mulched film) water conserved best,T₃(ridge mulched film and ditch mulched straw) was the next-best pattern,and T₁(ridge mulched film and ditch no-mulched) was the third.In compared with the control,the volume of soil water consumption of T₂,T₃ and T₁ decreased by 49.87mm,43.06mm and 29.39mm.and the volume of water requirement of T₂,T₃ and T₁ decreased by 81.66mm,69.20mm and 48.45mm,the average of crop coefficient decreased by 0.12,0.16 and 0.09.Micro-catchment patterns can increase maize production and water use efficiency in varying degrees,especially T₃ and T₂.
