[0026] A method for preventing and controlling banana fusarium wilt based on bacillus subtilis NCD-2, comprising the following steps: 1) applying 1000 kg / mu of organic compost in the banana orchard experimental plot 1 soil, turning and mixing into the soil, and sprinkling water to control soil moisture at 30%;
[0027] 2) Transplant the banana seedlings to the experimental plot 1 in the banana orchard, and use diluted to the total strain concentration of 10 4 The bacillus subtilis NCD-2 bacterial agent of cfu / mL is sprayed to seedling rhizome, 1.5kg / plant, apply once every 20 days;
[0028] 3) Use 0.1 mg / L sodium binitrate at a ratio of 1:1.5:1, 300 times the polmeaxyl water solvent, and 400 mL of 2% MgSO4 nutrient solution for root irrigation, once every 15 days, for 7 consecutive times.
[0029] Specifically, the Bacillus subtilis NCD-2 bacterial agent contains silicate bacterial strains, phosphorus bacterial strains, and the total amount of nitrifying bacterial strains is ...

[0032] A method for preventing and controlling banana fusarium wilt based on bacillus subtilis NCD-2, comprising the following steps: 1) applying 1500 kg / mu of organic compost in the banana orchard experimental plot 2 soil, turning and mixing into the soil, and sprinkling water to control soil moisture at 30%;
[0033] 2) Transplant the banana seedlings to the experimental plot 2 in the banana orchard, and use diluted to the total strain concentration of 10 5 The bacillus subtilis NCD-2 bacterial agent of cfu / mL is sprayed to seedling rhizome, and 2kg / plant is applied once every 20 days;
[0034] 3) Use 0.1 mg / L sodium binitrate at a ratio of 1:1.5:1, 300 times the polmeaxyl water solvent, and 400 mL of 2% MgSO4 nutrient solution for root irrigation, once every 16 days, for 7 consecutive times.
[0035] Specifically, the Bacillus subtilis NCD-2 bacterial agent contains silicate bacterial strains, phosphorus bacterial strains, and the total amount of nitrifying bacterial strai...

[0038] A method for preventing and controlling banana fusarium wilt based on bacillus subtilis NCD-2, comprising the following steps: 1) applying 1500 kg / mu of organic compost in the banana orchard experimental plot 3 soil, turning and mixing the soil, and sprinkling water to control soil moisture at 32%;
[0039] 2) Transplant the banana seedlings to the experimental plot 3 in the banana orchard, and use diluted to the total strain concentration of 10 4 The bacillus subtilis NCD-2 bacterial agent of cfu / mL is sprayed to seedling rhizome, 1.5kg / plant, apply once every 26 days;
[0040] 3) Use 0.03 mg / L sodium binitrate at a ratio of 1:1.5:1, 320 times the bolaxyl water solvent, and 500 mL of 3% MgSO4 nutrient solution for root irrigation, once every 20 days, for 7 consecutive times.
[0041] Specifically, the Bacillus subtilis NCD-2 bacterial agent contains silicate bacterial strains, phosphorus bacterial strains, and the total amount of nitrifying bacterial strains is more t...
