温室樱桃番茄水分效应及水分生产函数

以温室樱桃番茄为试验材料,通过对全生育期5个土壤水分水平的控制,研究了不同灌水水平对日光温室樱桃番茄产量?品质及水分利用效率的影响。结果表明,樱桃番茄的产量?品质与土壤水分含量密切相关,土壤相对水分含量为50%～60%、60%～70%、80%～90%和90%～100%的产量与70%～80%的相比,分别减少了39.70%、22.53%、3.43%和20.30%。土壤水分适宜(70%～80%)不仅可以提高樱桃番茄的产量,而且可以提高水分利用效率,水分利用效率随灌水量的增加先增加后降低,且在70%～80%水分利用效率最高。

Water Use Efficiency and Water Production Function of Cherry Tomato in Greenhouse

In order to seek for suitable irrigation control index for cherry tomatoes in sunlight greenhouse,a field plot experiment was conducted in greenhouse in this paper.By controlling the different soil moisture in the whole growing season,tomatoes yield,fruit quality and water use efficiency in greenhouse were studied under different irrigation treatment,designed to select the best soil for irrigation,provide a theoretical basis for agricultural production.The experimental result showed that yield and quality of processed tomato had close relation with soil moisture content.The yield of 50% to 60%,60% to 70%,80% to 90% and 90% to 100% compared to 70% to 80%,decreased by 39.70%,22.53%,3.43% and 20.30%.While suitable soil moisture(70% to 80%) can not only increase tomatoes yield,but also increase water use efficiency and irrigation use efficiency,water use efficiency increased with irrigation water increased and then decreased;in 70% to 80% treatment was the optimization.
