Abstract: In order to understand the effects of different furrow and mulched ridge combined farming practices on water moisture conversation and water saving of spring Mung bean planted farmland, the study investigated the soil water contents, yield, water use efficiencies and economic efficiencies of spring Mung bean under five different furrow and mulched ridge combined farming practices in two consecutive years. The study found that during the whole growth period of spring Mung bean, the two year average 0-100cm soil water storage under the different farming practices significantly increased by 7.96-22.76mm compared with that under the flat farming practice (T-Test P<0.05), respectively. The two-year average seed yield under the different farming practices significantly increased by 0.63%-24.53% compared with that under the flat farming practice respectively. The annual WUEs and yield-based incomes and net incomes under the different practices increased by30.03%-68.80% and 27.66%-51.16% and 28.99%-78.92% compared with those under the control practice, respectively; and at the same yield of Mung bean, the percentage of saved water and water saving efficiencies of Mung bean increased by 22.73%-40.38% and 339.48-603.12RMB Yuan /hm2 compared with those under the flat farming practice, respectively. The study indicated that double-furrow and mulched ridge combined water micro-collecting practice (practice 4) performed best in water retention and conservation, suitable to promote and adopt in semi arid regions and ecologically similar regions.
