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.
