Embodiment 1
[0045] 1) Ditch circularly within the radius of 0.8-1.5m of the beech tree trunk; the position of the ditch expands outward year by year according to the age of the beech tree, the excavation width is controlled at 60-100cm, and the excavation depth is controlled at 40-50cm;
[0046] 2) 13 parts of Streptomyces flavinus CICC 23627 fermentation broth, 12 parts of 300 times liquid Condirad (Paenibacillus polymyxa fine granule), prepared solution for root irrigation, 1500 mL per plant, as treatment 1;
[0047] 3) Streptomyces flavinus CICC 23627 fermentation broth 13 parts by mass, 300 times liquid Condilet (Paenibacillus polymyxa granule) 12 parts, citral fungicide 5 parts, 500 times liquid carbendazim for sterilization 3 parts of prepared solution for root irrigation, 1500mL per plant, as treatment 2;
[0048] 4) 13 parts by mass of Streptomyces luteus CICC 23627 fermentation broth, 5 parts of citral fungicide, and 3 parts of 500-fold liquid carbendazim fungicide were prepared ...
Embodiment 2
[0058] The medicament for the prevention and treatment of beech root rot comprises the following components in parts by mass: 18 parts of Streptomyces luteus CICC 23627 fermented liquid, 15 parts of Condirad, 8 parts of citral fungicide and 6 parts of carbendazim fungicide .
[0059] The method for using the above-mentioned control agent to prevent and treat beech root rot may further comprise the steps:
[0060] 1) each component is prepared the prevention and treatment agent of beech root rot according to the ratio of parts by mass;
[0061] 2) Ditch circularly within the radius of 0.8-1.5m of the beech tree trunk, the width of the ditch is controlled at 60-100cm, and the depth of the ditch is controlled at 40-50m;
[0062] 3) Pour the control agent of zelkova root rot into the annular ditch, and carry out the root irrigation treatment according to 1000-1500mL of each zelkova;
[0063] 4) After the root irrigation is completed and the control agent penetrates into the soil...
Embodiment 3
[0066] It is basically the same as Example 2, except that the control agent includes the following components in parts by mass: 15 parts of Streptomyces flavinus CICC 23627 fermented liquid, 13 parts of Kangdirad, 6 parts of citral bactericide and multibacterial Ling bactericide 5 parts.
[0067] The various components of the prevention and control agent of the present application cooperate with each other to increase efficiency, and the control effect is obvious, and the microbial agent effectively inhibits the growth and reproduction of pathogenic bacteria of beech root rot and provides a favorable environment for the reproduction of beneficial microorganisms .
