Abstract Aiming at obstacles of vegetable soil after successive cropping and deterioration of vegetable
quality in greenhouse，this paper takes tomato（Lycopersicon esculentum Mill.）grown in a greenhouse at
outskirts of Beijing in spring as research objective，and studies the effect of wood peat and other material as soil
conditioners on tomato yield，quality and facility soil improvement．The results showed that the yield of tomato
treated with wood peat plus potassium hydroxide（WP+KOH）increased 16.73%，and the VC content increased
55.77%．Meanwhile，the WP+KOH treatment also increase the contents of soil available nutrients and pH．The
treatments of wood peat，wood peat plus fungicide had no significant effects on fruit yield and quality and available
nutrients．All treatments by wood peat and other additional material had the trend of reducing soil surface salt
accumulation．Therefore，wood peat and its material mixture had a positive effectiveness on greenhouse tomato
growth and soil improvement．The WP+KOH treatment was the best.
