| 摘 要： | 通过田间定位试验研究了水泥极硬覆盖对棉田和玉米田土壤蒸发、作物蒸腾、土壤温度变化、作物生长发育状况及产量和水分利用效率的影响。结果表明：硬覆盖能减少农田土壤无效蒸发，调节土壤水分、降低土壤温度变化幅度，促进春播作物全苗壮，提高作物产量和水分 效率。

| Abstract: | The effects of concret mulch on evaporation,transpiration,evapotranspiration,soil temperature,yield of cotton and corn,water use efficency were studied by field experiments.the results showed that concret mulch cover effectively increased transpiration,yield and water use efficency and greatly reduced soil evaporation loss and the amplitude of daily and seasonly soil temperature,water content variations. |
