摘      要：Amplifying drought stress and high precipitation variability impair dryland wheat *** problems can potentially be minimized by using plastic mulch(PM)or straw mulch(SM).Therefore,wheat grain yield,soil water storage,soil temperature and water-use productivity of PM and SM treatments were compared with no mulch(CK)treatment on dryland wheat over a period of eight *** to the CK treatment,PM and SM treatments on average significantly increased grain yield by 12.6 and 10.5%,*** to the CK treatment,SM treatment significantly decreased soil daily temperature by 0.57,0.60 and 0.48℃for the whole seasons,growing periods and summer fallow periods,*** contrast,compared to the CK treatment,PM treatment increased soil daily temperature by 0.44,0.51 and 0.27℃for the whole seasons,growing periods and summer fallow periods,*** soil temperature under SM allowed greater soil water storage than under *** water storage pre-seeding was 17%greater under the SM than under the PM *** water storage post-harvest was similar for the PM and SM treatments,but evapotranspiration was 4.5%higher in the SM than in the PM ***,water-use productivity was 6.6%greater under PM than under the SM ***,PM treatment increased dryland wheat yield and water-use productivity,while straw mulch increased soil water storage.
