摘　　要：采用单因素随机区组试验，以微成水直接灌溉为对照，研究不同微成水利用方式对番茄生长发育、产量和品质、土壤理化性质等的影响。结果表明，与微成水直接灌溉相比，净水灌溉增产44．78％，0～20、20～40cm土层电导率分别降低67．21％、10．61％，果实中Vc、可溶性糖、可滴定酸、可溶性固形物差异均极显著，净水灌溉能够提高水分利用效率，但影响果实品质的提高；混灌模式增产26．56％，果实中营养物质量高于净水灌溉，但低于微咸水直接灌溉，根系分布密集层盐分累积不明显，生产成本降低50％。混灌模式为微成水淡化处理后最佳利用模式；高品质番茄生产以微成水直接灌溉为宜。According to the experiments designed by single factor randomized block, the effects of different brackish water utilization modes on tomato growth, yield, quality and soil physicochemical property prop- erties were studied with the brackish water irrigation as the control. The results showed that compared to brackish water irrigation, the yield under purified water irrigation was improved by 44.78%, soil electrical conductivity in 0-20 cm and in 20-40 cm decreased 67.21% and 10.61% respectively, and Vc, total sugar, titratable acid, dissolvable solid content all had an extremely significant differences; Water use efficiency increased and fruit quality was affected under purified water irrigation. Under mixed irrigation, the yield increased by 26.56 %, the nutrient content of fruit was higher than that under purified water irrigation but it was less than that uner brackish water irrigation, the salt in concentrated root layer was not obviously accumulated, and the production cost reduced by 50%. The mixed irrigation could be treated as the best utilization pattern after brackish water being purified and brackish water irrigation was suitable for high-quality tomato production.
