摘　　要：在充分灌溉、轻度水分胁迫和重度水分胁迫条件下,秸秆覆盖可以有效降低作物需水量,同无秸秆覆盖对照相比分别降低了14.42%、9.58%和6.47%。秸秆覆盖可以提高土壤的保墒作用;各种水分条件下,秸秆覆盖对于作物产量都有着显著影响。The effects of deficit irrigation and straw mulch on the growth parameters of winter wheat were studied in the greenhouse. The result showed that straw muIch decreased root biomass by 14. 42% ,9.58% and 6.47% respectively under full irrigation, mild water stress and serious water stress compared with no straw mulch. It also showed that straw mulch had significant effects on the yield of winter wheat.
