The invention discloses preparation of a
trichoderma composite
flora and application of the
trichoderma composite
flora in prevention and control of
crop fusarium wilt and improvement of soil, and relates to the field of agricultural production, and the composite
flora is prepared by mixing
trichoderma asperellum (5 * 10 < 7 > CFU / L),
streptomyces (108 CFU / L), Chinese monospora (108 CFU / L), ensifer adhesion (108 CFU / L),
pseudomonas nitroreducens (108 CFU / L) and
paenibacillus alvei (108 CFU / L) according to the volume ratio of 6: 1: 1: 1: 1: 1: 1: 1 (V: V). According to the composite flora in the scheme, the composite flora is used for promoting growth of cucumber plants, and compared with a clear water control group (Foc), the
fresh weight of cucumbers is increased by 55.51%, the stem
diameter is increased by 12.76%, and the
plant height is increased by 34.25%. The composite flora can also effectively prevent and treat
fusarium wilt of cucumbers, and the prevention and
treatment effect reaches 71.43%. Compared with the
Trichoderma asperellum FJ035
treated group, the
Trichoderma asperellum FJ035 has the advantages that the
Trichoderma asperellum FJ035 is better than the
Trichoderma asperellum FJ035 which is independently applied in the aspects of promoting the growth of cucumber plants and preventing and treating cucumber
fusarium wilt, and compared with the
Trichoderma asperellum FJ035
treated group, the
control effect is improved by 56.25%. Meanwhile, the composite flora can be used for improving soil and preventing and treating multi-
crop fusarium wilt.
