摘　　要：为探明日光温室越夏番茄在纸膜覆盖下的适宜定植期,试验开展不同定植期对番茄生育期、果实品质、产量及经济效益的影响研究。结果表明,7月5日定植的番茄生育期为174 d,生长期间活动积温为3 576.41℃,产量达6 626 kg/667 m^(2);8月5日定植的番茄生育期为192 d,活动积温为3 416.76℃,产量达7 332 kg/667 m^(2)。7月定植的番茄生长时期积温较高,番茄前期产量高,但后期产量较低。8月定植的番茄中后期产量稳定,其产量较高,经济效益也优于7月定植的番茄。In order to explore the suitable planting period for over-summering tomatoes in solar greenhouses under paper film coverage,experiments were conducted to investigate the effects of different planting periods on tomato growth period,quality,yield and economic benefits.The results showed that the tomato planted on July 5th had a growth period of 174 days,with an active accumulated temperature of 3576.41℃ and a yield of 6626 kg/667 m^(2).The tomato planted on August 5th has a growth period of 192 days with an active accumulated temperature of 3416.76℃ and a yield of 7332 kg/667 m^(2).Tomatoes planted in July have a higher accumulated temperature during their growth period,resulting in higher yields in the early stages but lower yields in the later stages.Tomatoes planted in August have stable yields in the middle and later stages,with higher yields,good prices and higher economic income than tomatoes planted in July.
