摘　　要：通过小区试验研究了不同覆盖保墒灌溉措施对土壤水分动态变化、土壤温度、葡萄生长状况、生理生态指标以及产量等的影响。结果表明:与对照相比,覆盖措施明显减少了土壤水分蒸发,提高了蓄水保墒作用;覆盖措施可明显提高土壤表层温度,但随深度的增大,影响程度逐渐减小;保墒处理的果树生长势强、枝条增长量大、果粒大、产量高。草帘子覆盖措施与塑料薄膜覆盖措施效果相当。Based on the experiment, we studied the effect of different mulching on soil moist, soil temperature, status of grape growing and final yield. The results showed that, compared with CK, soil moisture evaporation significantly decreased at coverage measures, which enhanced water reserving and soil moisture keeping. Topsoil temperature were obviously enhanced. But with increased depth of soil, the impact degree of soil temperature gradually reduced. Comprehensive analysis the growth vigor, growth, fruit size and yield in coverage measures were superior. The effect of Straw cover and plastic film cover was equal.
