Abstract: The vegetable f ields topsiol( 0- 20 cm) of solar greenhouse and the outdoor open field topsoil were collectedin Jinan, Shandong province to measure the content of the organic C, alkal-i N, avai-l P, avai-l K, pH, electric conductiv-ity rate etc.The result showed that: the averaged content of organic C in the vegetable f ield siol of solar greenhouse was 21.6 g/ kg, higher than that in the open field soil by 77%. The soil alkal-i N content, the avai-l P content, the avai-l K contentin the greenhouse were 115.4, 122.4, 455.5 mg/ kg respectively, and the increased percentage were 66.7%,472.0%and 173.4% respect ively compared with the open field soil.The soil alkal-i N accumulation and the greenhouseage have no obvious relation,The solar greenhouse soil avail Pcontent and the solar avail K content were positive with thegreenhouse age. The solar greenhouse soil pH averaged 7.90, lower than that of the open field soil by 0??23. The electric conductivity of the siol was 0.457 ms/ cm, the soil electric conductivity rate was consumedly higher than that in the opef ield soil, increased by 60.9% than that of open field soil. The vegetable soil of the solar greenhouse were acidify and salted and the nutrient greatly accumulated.

Key words: Solar greenhouse, Soil, Nutrient accumulation
