摘　　要：以桃太郎为试材,研究了追肥期间不同灌水量对番茄生长、品质和产量的影响。试验结果表明,加大灌水量可提高株高和单果质量,但对茎粗和坐果数没有明显改善。每667 m^(2)每次灌水量为2400、3000 L的番茄平均株高分别较灌水量1200 L显著提高12.05%和19.04%;每667 m^(2)每次灌水量为2400 L比每次灌水600 L单果质量提高19.85%。每667 m^(2)每次灌水3000 L的番茄产量较每次灌水600 L增长44.02%,而每667 m^(2)每次灌水3000 L的番茄较每次灌水1200 L糖度降低12.97%~32.56%。5个处理中,追肥期间以每667 m^(2)每次灌水1200 L的效益最高,推荐上海地区在番茄生产上实施,共灌2次。Taotailang was used as the test material to study the effects of different irrigation amounts on the growth,quality and yield of tomato during topdressing.The results showed that increasing the irrigation amount could improve the plant height and single fruit weight,but there is no significant improvement in the stem diameter and fruit set number.The average plant heights of tomatoes with irrigation amounts of 2400 and 3000 L/667 m^(2) were significantly increased by 12.05%and 19.04%compared with 1200 L/667 m^(2),respectively.The single fruit weight with the irrigation amount of 2400 L/667 m^(2) increased by 19.85%compared with 600 L/667 m^(2).The yield with the irrigation amount of 3000 L/667 m^(2) increased by 44.02%compared with600 L/667 m^(2).While the sugar content of tomatoes with the irrigation amount of 3000 L/667 m^(2) decreased by 12.97%-32.56%compared with 1200 L/667 m^(2).Among the five treatments,irrigation amount of 1200 L/667 m^(2) during topdressing had the highest benefit,which was recommended for tomato production in Shanghai,with a total of two irrigations.
