摘要： 以高垄覆膜水肥一体化技术(FG+H)为试验处理，膜下沟灌(FP)为对照，通过田间试验研究了高垄覆膜水肥一体化技术对设施土壤理化性状及蔬菜产量的影响。结果表明，定植后26 d～55 d， FG+H处理明显提高了20 cm处地温；定植后118 d～154 d，5 cm、10 cm、15 cm、20 cm、25 cm处地温均低于FP。FG+H处理的表层土壤饱和导水率明显提高，是FP的2.2倍。FG+H处理可明显降低0～60 cm土壤硬度，而对土壤容重无明显影响。FG+H处理0～20 cm土壤全氮、有效P、速效钾、有机质含量比FP分别提高18.4%、47.6%、34.9%和20.9%，且明显降低了0～200 cm土壤剖面硝态氮含量。FG+H处理相对FP有缓解土壤酸化和盐化的趋势。FG+H处理番茄采收期相对FP推迟约10 d左右，但FG+H处理番茄总产量相对FP提高了19.9%。本研究结果表明，FG+H处理不仅明显改善了设施土壤理化性状，而且番茄产量也明显提高。

Abstract: The experimental treatment is combination of plastic mulching and high-ridge and fertigation (FG H), membrane under furrow irrigation (FP) as the control, a field experiment was carried out to study that effect of combination of plastic mulching and high- ridge and fertigation on soil physiological and chemical characteristics and yield of vegetables in sunlight greenhouse. The results showed that: the soil temperature in 20 cm of plastic mulching of high-ridge combination fertilization(FG H) increased significantly at 26 to 55 days after planting, The soil temperature of plastic mulching of high-ridge combination fertilization (FG H) lower than membrane under furrow irrigation (FP) in soil depth of 5, 10, 15, 20, 25 cm separately, after 118 to 154 days planting. Plastic mulching of high-ridge combination fertilization (FG H) increased significantly surface soil saturated hydraulic conductivity, that was 2.2 times of membrane under furrow irrigation (FP). And soil hardness reduced significantly in 0-60 cm soil depth, but had no effect on soil bulk density. Plastic mulching of high-ridge combination fertilization (FG H) reduced significantly nitrate nitrogen in 0-200 cm soil profile, And reduce the risk of soil acidification and salinization. FG H treatment tomato harvest period relative FP delayed about 10 days, but The FG H treatment tomato yield increased by 19.9% relative to FP. Research results showed that, combination of plastic mulching and high-ridge and fertigation (FG H) not only significantly ameliorated the soil physical and chemical properties and the yield of tomato increased significantly in sunlight greenhouse.
