This experiment was done to evaluate the effects of green manure cropping in green house soil on the changes of soil nutrients and soil microorganisms. The biomass of green manure crop was the highest in ryegrass and nitrogen absorption was the highest in hairy vetch. After cropping, soil phosphate content was the lowest in ryegrass, however, biomass C was the highest of all the green manures. Nitrogen uptake of plant and nitrogen content of the soil after the experiment showed a negative correlation. Total N content of soil was increased in hairy vetch plot, but decreasing tendency showed in the ryegrass and common crabgrass plots. In this results are summarized that green manure cropping greatly reduced salt accumulation in green house.
