封闭式管道栽培番茄新技术节水性研究

为研究新型全封闭式管道栽培模式对番茄品质、产量以及水肥利用率的效果，以‘欧官’番茄为试验材料，研究全封闭管道栽培与膜下滴灌土壤栽培2 种栽培模式对番茄植株生长、果实品质和产量、耗水量以及水分利用效率等方面的影响。结果表明，与膜下滴灌土培番茄相比全封闭管道栽培不仅促进了番茄植株株高、茎粗，而且提高了番茄果实中可溶性糖、维生素C以及糖酸比，提高了番茄果实的风味，增加了产量；在对番茄前四穗果的测产中，全封闭管道栽培模式比膜下滴灌土培高产15.0%，耗水量相应减少764.0 m3/hm2，水分利用效率提高了49.3%。

Study on the New Water Saving Technique in Closed Pipeline Culture of Tomato

In order to study the effects on tomato cultivation mode quality, yield and fertilizer use efficiency of new fully enclosed pipeline, with‘Ou Guan’tomato as test material, we studied the effects of the closed pipeline soil cultivation and drip irrigation cultivation of two modes on tomato plant growth, fruit quality and yield, water consumption and water use efficiency and other aspects. The results showed that closed pipeline not only promoted the tomato plant height, stem diameter, but also improved the tomato soluble sugar, vitamin C and sugar-acid ratio, improved tomato fruit flavor and increased production. In tomato fruit yield monitor, yield of closed pipeline soil culture cultivation mode was 15.0% higher than that of drip irrigation, water consumption reduced accordingly 764.0 m3/hm2, water use efficiency was improved by 49.3%.
