摘要
为探索滨海盐碱地区温室蔬菜的水、肥、氧管理模式,对温室番茄进行不同的滴灌处理试验,分析了施肥灌溉和加氧灌溉对番茄生长、产量、品质和水分利用效率的影响。结果表明,不同水肥处理对番茄株高和茎粗的影响差异不显著;中水低氮处理产量最高,较高水高氮处理增产45.3%;各处理间的灌溉水利用效率和果实品质都有明显的差异,综合考虑产量及成本等因素,中水低氮和低水低氮灌溉为滨海盐碱地区最适宜的滴灌施肥模式。滴灌加氧对盐碱地番茄生长有明显的促进作用,与不加氧处理相比,株高、茎粗增加4.6%和4.3%,增产12.1%,可溶性固形物、总糖、可滴定酸和Vc质量分数均提高。
In order to investigate the management mode of water, fertilizer and oxygen on greenhouse＇s vegetable in coastal salt-alkali region, experiments were conducted under the different treatments of drip irrigation on greenhouse tomato, and the effects of fertigation and oxygation on tomato growth, yield, fruit quality and water use efficiency were analyzed. The results indicated that the effects of different ferti- gation on tomato plant height and stem diameter were not significant; the highest yield was obtained under the treatment of medium water and low nitrogen, and increased by 45.3~ compared to the treatment of high water and nitrogen. There were obvious differences between the treatments on WUE and fruit quali- ty~ Giving that production cost and other factors, treatment of medium or low water and low nitrogen were the most two appropriate fetigation patterns in coastal salt-alkali region. There was obviously promoted ef[ect of oxygation on tomato growth~ Compared to the contrast, plant height, stem diameter and the yield increased by 4.6%, 4.3% and 12.1%, while the contents of soluble solids, total sugar, organic acid and Vc were obviously improved.
