Abstract: In order to alleviate the serious shortage of water resources in the area of reducing groundwater mining in Hebei Province and improve the water use efficiency of spring maize, a field of different coverage methods on spring maize were conducted. Using Xianyu 335 as the material, and the two kinds of water conditions were set up:irrigated 75 mm (W) at bell stage and rain-fed (R); four mulching treatments such as sub-soil mulch film covering (PM), ssub-soil mulch film covering with porous on film (P0M), corn stalk covering (SM), and normal planting (NP), were carried after autumn ploughing to examine spring maize of growth and development, soil water consumption and yield. Results showed that under rain-fed condition, mulching increased yield by 18.0%-24.9% compared with NP, however, the difference between SM and NP in the yield was not significant. Under rain-fed condition, the water use efficiency during growing season of PM, P0M and SM increased by 50.5%, 41.0% and 12.0% than NP, respectively; The annual water use efficiency was increased by 63.2%, 54.6% and 19.1% than NP, respectively. Additionally, the water saving effect of PM and P0M were significantly better than SM. The results under irrigation at bell stage were the same as those under rain-fed cultivation. The irrigation increased both of yield and water consumption, but relatively reduce the water use efficiency, which indicated that irrigation under mulch produced extravagant water consumption. Taken together, under the rain-fed condition, the sub-soil plastic film mulching was a new way for spring maize production as it can considerably coordinate annual water distribution, improve water use efficiency and increase yield in Hebei Plain.
