为确定番茄冬春茬生产中的适宜灌水量，以日光温室番茄为试验材料，从定植缓苗后开始至收获进行不同灌水量处理，试验设每次灌水量300m^3／hm^2（CK）、225m^3／hm^2、150m^3／hm^2和75m^3／hm^2计4个处理，共灌水8次，研究不同灌水量对番茄产量和品质的影响。结果表明：随着灌水量的减少，番茄果实可溶性固形物含量、可滴定酸含量和Vc含量以及灌溉水利用率均呈逐渐增加趋势，产量呈逐渐降低趋势。其中，每次灌水量为225m^3／hm^2 处理的产量较CK降低了0．45％，灌溉水利用率却提高了26．12％，而且增加了果实的可溶性固形物、可滴定酸和Vc含量；每次灌水量为150m^3／hm^2和75m^3／hm^2处理的产量较CK极显著降低，分别降低了10．08％和21．01％。综合分析认为，番茄冬春茬生产中较适宜的灌水量为每次灌水225m^3／hm^2。

In order to determine the suitable irrigation amount for the spring-winter production of tomato, 4 irrigation volume including 300 ma/hm^2 （CK） , 225 m^3/hm^2, 150 ma/hm^2 and 75 m^3/hm^2 were set, and the effects of different irrigation amount on the yield and quality of tomato in greenhouse were studied. The results showed that with the decreasing of irrigation amount, the soluble solid content, titratable acid content, Vc content and irrigation water use efficiency of tomato increased, while the yield decreased gradually. When the irrigation amount was 225 m^3/hm^2, the yield decreased by 0. 45% , while the irrigation water use efficiency increased by 26. 12%, and the soluble solids content, titratable acid content and Vc content increased. The yield decreased significantly when the irrigation amount was 150 m^3/hm^2 and 75 m^3/hm^2, which decreased by 10. 08% and 21.01%, respectively. It was concluded that the optimum irrigation amount was 225 m^3/hm^2
