Study and Demonstration on the Key Technique of the Soil Improvement Impact by BGB Microbial Blends

摘要

There are a lot of gravel and abandoned mine land in Mentougou District. The structure of its topsoil is poor, and the nutrient content is very low. The plow layer is shallow, only about 15-18 cm (Figure 1) . Year precipitation is only about 300 mm. Due to the drought , insufficient rainfall and other climatic factors, there is hardly natural vegetation cover. And it is even more difficult for the plant with a certain economic value to grow. Because of the low vegetation coverage, when it rains, it is very easy to create soil erosion, making soil more infertile and plow layer lighter. It impacts local ecological environment and the agricultural sustainable development seriously.
