摘　　要：为探讨科学合理的灌溉技术,用田间小区栽培试验的方法,研究了日光温室栽培番茄,普通渗灌、节点渗灌、滴灌和沟灌等4种灌溉方法对番茄生长、品质和产量的影响。结果表明:不同灌溉方法对番茄的株高、茎粗均无明显影响,而对果实膨大速度影响显著。其中,第一穗果果径的大小顺序是滴灌>普通渗灌>节点渗灌>沟灌;第二、第三穗果果径的大小顺序相同,均为普通渗灌>节点渗灌>滴灌>沟灌。不同灌溉方法番茄果实的Vc、可溶性糖含量以及总酸度和糖酸比均有显著差异,总的来看滴灌、普通渗灌和节点渗灌的Vc、可溶性糖含量较高而总酸度较低。番茄产量的顺序为普通渗灌>节点渗灌>滴灌>沟灌。节点渗灌水分生产效率最高。由此可以得出,从灌溉方法的效果而论保护地栽培番茄应优选节点渗灌。A experiment was conducted to study the effect of four irrigation methods： filtration irrigation, drip filtration irrigation, drip irrigation and furrow irrigation on plant growth, fruit quality and tomato yield in greenhouse in order to discuss scientific and optimum irrigation methods. Results showed that different irrigation methods were not related to plant height and plant stem of tomato significantly, but related to fruit diameter significantly. The first fruit diameter was drip irrigation〉filtration irrigation〉drip filtration irrigation〉furrow irrigation and the second and the third fruit diameter was filtration irrigation〉drip filtration irrigation〉 drip irrigation〉furrow irrigation. There were significant relationships between different irrigation methods and vitamin C content, soluble sugar content,total acidity and sugar-acidity ratio. Vitamin C content and soluble sugar content in drip irrigation, filtration irrigation and drip filtration irrigation was higher and more preferable, but total acidity was lower. The tomato yield was filtration irrigation〉drip filtration irrigation〉 drip irrigation〉furrow irrigation. Water productivity of drip filtration irrigation was the highest. The results indicated that drip filtration irrigation was more preferable for tomato production in greenhouse.
