Embodiment 1
[0025] The parts by weight of the raw materials in the invention are: 80 parts of weak acid electrolyzed water, 20 parts of absolute ethanol, 3 parts of allicin, 1 part of Cnidium chinensis extract and 1 part of emodin methyl ether.
[0026] The concrete preparation steps of this technical scheme are as follows:
[0027] 1) After uniformly mixing 1 part of emodin methyl ether and 1 part of Cnidium chinensis extract with 80 parts of weak acid electrolyzed water, keep it warm at 50°C for 20 minutes to obtain solution a for later use;
[0028] 2) Evenly mix 3 parts of allicin with solution a, let it stand for 20 minutes, and obtain solution b for later use;
[0029] 3) Evenly mix 20 parts of absolute ethanol with solution b to obtain the special organic fungicide for Dendrobium officinale;

[0041] The parts by weight of the raw materials in the invention are: 100 parts of weak acid electrolyzed water, 40 parts of absolute ethanol, 7 parts of allicin, 5 parts of Cnidium chinensis extract and 3 parts of emodin methyl ether.
[0042] The concrete preparation steps of this technical scheme are as follows:
[0043] 1) After uniformly mixing 3 parts of emodin methyl ether and 5 parts of Cnidium chinensis extract with weak acid electrolyzed water 100, keep it warm at 50°C for 20 minutes to obtain solution a for later use;
[0044] 2) Evenly mix 7 parts of allicin with solution a, let stand for 20 minutes, and obtain solution b for later use;
[0045] 3) uniformly mix 40 parts of absolute ethanol with solution b to obtain the special organic fungicide for Dendrobium officinale;
[0046] Soil was extracted from seedbeds with serious brown spot and soft rot diseases of Dendrobium candidum, and then Fusarium oxysporum, European bacillus and pathogenic bacteria in the soil ...
