[Objective] We selected the cucumber to study the coupling effect of surface coverage with plastic film and maize straw on root growth and rhizosphere nutrients during fruiting period in greenhouse in order to provide the theoretical and technical support for the sustainable production of facility agriculture in cold and arid regions of North China.[Methods] Greenhouse experiment and laboratory test were used in this study.[Results] Treatments of combined coverage with plastic film and maize straw improved the content of organic matter

and promoted root growth of cucumber. Compared with the control treatment in later fruiting period in the experiment
the treatment with 0.72 kg/m2 of straw and covered with film produced the best effect
