The agricultural series products of VRMQE can stimulate the natural ecological response in the soil, inhibit the reproduction of pathogenic bacteria through the biological antagonism of natural probiotics, enhance the immunity of plants, and form an early biological barrier. At the same time, various trace elements such as nitrogen, phosphorus and potassium in the soil are activated through microbial metabolism, which improves the nutrient absorption rate of crops and reduces the application of chemical fertilizers and pesticides. This project is suitable for all kinds of fields, greenhouses, horticultural planting.
