AI Technical Summary
Technical Problem
Newly reclaimed farmland has low soil fertility, especially low organic matter content, which leads to poor crop growth and low yield. Existing technologies are insufficient to effectively improve soil fertility.
Method used
A combination of microbial strains, including Bacillus amyloliquefaciens WK1, white-rot fungus NDM3-2, and Trichoderma spirulina HJR7, was applied in combination to soil containing straw and shiitake mushroom residue for an open-field pot experiment on rice to promote soil organic matter accumulation and microbial activity.
Benefits of technology
It significantly increased soil organic matter content, promoted rice growth, improved soil fertility, increased crop yield, and enhanced soil microbial abundance and diversity.

Abstract
The invention discloses microbial combined bacteria and a method for improving fertility of newly-cultivated land. The method comprises the following steps: combining every two of bacillus amyloliquefaciens WK1, white rot fungi NDM3-2 and trichoderma helichum HJR7 to form three combined bacteria; the three combined bacteria are applied to soil containing straw and lentinus edodes residues respectively, and a pot experiment (rice and white clover crop rotation) for two years is carried out with no addition of any bacteria as a contrast; analyzing the physical and chemical properties of the soil and the microbiological indexes of the soil; and according to an analysis result, the combination of the white rot fungi NDM3-2 and the trichoderma helichum HJR7 is confirmed to be an ideal scheme for improving the fertility of the newly-cultivated land.
