用 Ｅ Ｍ 制成的发酵肥，在矿毒土的水稻盆栽试验中，能有效的恢复矿毒土壤的生产能力，水稻产量显著地高于施用化肥等其他处理的产量，但后茬油菜仍会受重金属毒害不能生长，土样化验结果表明： Ｅ Ｍ 发酵肥对土壤中重金属的降解，在一季试验中效果不显著，虽有缓慢降解趋势，但土壤中重金属含量仍旧很高。
The fermented fertilizer made of E M can effectively restore the production capacity of mineral soils in rice pot experiments of mines and soils. The yield of rice is significantly higher than that of other treatments such as chemical fertilizers, but the rape remains after The test results of soil samples showed that the degradation of heavy metals in soil by E M fermented fertilizer was not significant in one season. Although the trend of slow degradation was, the content of heavy metals in soil was still high.
