摘　　要：[目的]研究民勤地区樱桃番茄的合理灌溉方法。[方法]试验设4个灌溉处理(C、T1、T2和T3),C为淡水灌溉,T1为先淡水后咸水灌溉,T2为先咸水后淡水灌溉,T3为咸水灌溉,研究不同生长阶段咸水灌溉对樱桃番茄生长、产量及质量的影响。[结果]T2处理为先咸水后淡水灌溉,负效应明显。T1和T3的作物产量明显降低,影响果实上市产量的土壤电导率临界值为4.10 d S/m。高于此值时每增高单位土壤电导率樱桃番茄产量下降7.85%。可溶性固形物总量在所有处理中不断上升。[结论]在生殖生长期使用淡水,在营养生长期使用咸水进行膜下滴灌是民勤地区种植樱桃番茄较为合理的灌溉方法。[ Objective] To establish a proper water irrigation strategy for cherry tomato. [ Method] A field experiment with four treatments was conducted to study the growth, yield and fruit quality of cherTy tomato irrigated with saline water at different growth stages. [ Result ] Saline irrigation at vegetative stage had obviously negative effect. Yield was significantly reduced in T1 and T3. The maximum ECe without yield reduction （the salt tolerance threshold） was 4.10 dS/m for the marketable yield. Above this threshold, the total yield was reduced by 7.85% per unit increase of soil salinity. TSS increased in all saline treatments. [ Conclusion ] It is feasible to irrigate cherry tomato using saline water at the vegetative stage and fresh water at the reproductive stage in Minqin area.
