摘　　要：试验设置5个灌水处理:每桶浇水量分别为2000(CK),1500(T1),1000(T2),500(T3),300mL(T4),研究不同水分亏缺程度对番茄生长发育、产量和果实品质的影响。结果表明:随着浇水量的减少番茄株高、株幅、茎粗、干物重、单株产量均明显下降,总灌水量与番茄的第1、第2穗果的单果重和单株产量之间均呈极显著相关关系,与果实中Vc、可溶性糖呈极显著负相关关系,与有机酸含量呈显著负相关关系。T1、T2处理产量下降幅度较小,而果实中Vc、可溶性糖含量较对照有显著的增加,是较好的处理。Five treatments of different irrigation level were conducted. The amount of irrigation per bucket was 2000,（CK）, 1500 （T1）, 1000（T2）, 500（T3）, 300（T4） respectively. The effects of different water deficit levels on the growth and development, yield and quality of tomato were studied. The ,esults indicate that the plant height, plant diameter, stalk diameter, dry matter accumulation and yield decrease obviously with the decline of irrigation amount. There was significant positive relation between total irrigation volume and the singe fruit weight of 1st, 2nd cluster and yield. Vc and soluble sugar content have significant negative relation with the total irrigation volume, organic acid content had negative relation with the total irrigation volume. T1 and T2 were better treatments than others which Ve, soluble sugar and organic acid content in fruit increase obviously and yield decrease slightly.
