The invention discloses a deodorizing bacteriostatic agent based on zeolite and plant extracts and a preparation method of the deodorizing bacteriostatic agent, and relates to the field of deodorizing and bacteriostasis. The deodorizing bacteriostatic agent based on the zeolite and the plant extract is prepared from the following raw materials in parts by weight: 40 to 70 parts of zeolite, 10 to 30 parts of montmorillonite, 2 to 7 parts of metal ion antibacterial compound and 5 to 15 parts of macleaya cordata extract concentrated powder. According to the technical scheme, the zeolite and the montmorillonite are used as base materials, and the metal ion antibacterial compound and the macleaya cordata extract concentrated powder with specific contents are added, so that the prepared odor-removing bacteriostatic agent has excellent odor-removing and bacteriostatic effects, is wide in antibacterial spectrum, and can better play a role in balancing odor-removing and bacteriostatic effects.

The invention discloses a sanguinarine sterilization composition containing a macleaya cordata extract and application of the sanguinarine sterilization composition. The sanguinarine sterilization composition mainly comprises sanguinarine and pydiflumetofen. The two components do not have cross resistance, the two medicaments have obvious synergistic effect after being combined according to a certain ratio, and a common agricultural bactericide dosage form is prepared by adding a proper amount of agricultural bactericide auxiliaries and has higher control effect on fungal diseases of crops. Through combined use of the formula, the dosage can be reduced, the drug resistance of germs to a single agent can be delayed, ecological damage and environmental pollution are effectively reduced, and the yield and quality of crops can be improved; the composition can efficiently prevent and control crop sickle root rot, increases a disease prevention spectrum, and can prevent common crop diseases such as anthracnose, leaf spot, early blight, brown blotch and gray mold at the same time.

The invention belongs to the technical field of animal feed, and particularly relates to a natural plant feed raw material capable of replacing aureomycin and a preparation method of the natural plant feed raw material. The traditional Chinese medicine composition is prepared from the following natural plant raw materials in parts by weight: 15 to 25 parts of radix astragali seu hedysari, 10 to 20 parts of fructus crataegi, 10 to 18 parts of fructus hippophae, 8 to 15 parts of fructus schisandrae chinensis, 8 to 15 parts of herba portulacae, 6 to 12 parts of flos lonicerae, 10 to 18 parts of radix codonopsis and 6 to 12 parts of macleaya cordata. The natural plant feed raw materials are from pure traditional Chinese medicines / natural plants, are free of antibiotics and chemical additives, and are used for replacing aureomycin to serve as feed additives or premix for fattening monogastric / ruminants such as pigs, cattle, sheep and horses.
