大棚多年连续栽培蔬菜，会使土传病害发生严重，土壤有机质下降，并由于覆盖农膜，雨水冲洗减少，下层无机盐上升，土壤盐碱化加重，严重影响蔬菜生产。如果在冬季轮作金针菇，可促使土壤盐分向下层移动，并由于保持了土壤潮湿，土壤的生态环境得到改变，使土传病菌基数下降。
Continuous cultivation of vegetables for many years in greenhouses will cause soil-borne disease serious, soil organic matter decreased, and due to cover plastic sheeting, reducing irrigation, lower inorganic salts, soil salinization aggravated, seriously affecting vegetable production. If the winter mushroom rotation, can promote soil salt to move to the lower, and due to keep the soil moist, the ecological environment of the soil is changed, so that the number of soilborne bacteria decreased.
