Microbial soil conditioner for lithified soil

Abstract

The invention provides a microbial soil conditioner for lithified soil, which is prepared from the following strains in percentage by mass: 5-45% of Bacillus megaterium ACCC No.11011, 15-40% of Bacillus subtilis ATCC No.6633, 5-30% of Rhodopseudom onas Palustris ATCCNo.33872, 10-30% of Candida utilis ATCC No.22023 and 20-35% of Azotobacter chroococcum ACCC No.10096.

Description

technical field [0001] The invention relates to a soil conditioner and a preparation method thereof, in particular to a microbial soil conditioner for lithified soil. Background technique [0002] Due to decades of predatory farming, the quality of cultivated land in many areas of our country has been seriously damaged due to the loss of nutrients. Too much reliance on the use of chemical fertilizers has led to soil degradation, shallower plow layers, poor arable performance, and reduced water retention capacity in cultivated land. The birth of chemical fertilizers brought farmers hope for a good harvest in a certain period of time. However, the disadvantages of long-term use of chemical fertilizers followed, and a series of problems such as soil compaction, chemical element residues, and environmental pollution surfaced, and even land lithification and desertification occurred. And with the rapid economic and social development and the acceleration of urbanization, China'...

Problems solved by technology

These bare soils have been exposed for a long time, water loss, and these soils are repeatedly compacted by large machinery during the infrastructure construction process, resulting in further loss of soil water and further compaction of the soil, resulting in soil lithification, which not only affects the ecological environment landscape, but also destroys the area. Moreover, some lithified soils still have serious hidden dangers of geological disasters, affecting the safety and stability of the main project, and even endangering people's lives and property safety
