Through research on salt accumulation, variation of pH and nutrient status of heliogreenhouse soils under mushroom cultivation in summer and autumn, it would found that mushroom cultivation affected salt accumulation, soil pH and soil nutrient status. The nutrient status of the soil under mushroom cultivation is characterized by soil NO₃^--N content ranging in a proper proportion of the soil available nitrogen, which could efficiently prevent excessive accumulation of nitrate in greenhouse soil from polluting the environment and doing harm to the plants and the human health.
