Embodiment 1

[0038] The preparation method of described antibacterial agent comprises the steps:

[0039] (1) be that the active carbon powder that mass volume ratio is 1:20 and mass percentage be 4% bamboo vinegar liquid mix, stir 0.5h, leave standstill 3 days, take out supernatant liquid namely bamboo vinegar liquid;

[0040] (2) The supernatant obtained in the step (1), that is, bamboo vinegar, was mixed with 0.5% chitosan in a volume ratio of 10:1, stirred for 3 minutes, and mixed uniformly to prepare the bacteriostatic agent.

Embodiment 2

[0042] The preparation method of described antibacterial agent comprises the steps:

[0043] (1) The activated carbon powder with a mass-volume ratio of 1:10 is mixed with 5% bamboo vinegar in mass percentage, stirred for 0.2h, left to stand for 1 day, and the supernatant is taken out, which is bamboo vinegar;

[0044] (2) The supernatant obtained in the step (1), that is, the bamboo vinegar, is mixed with a volume ratio of 1:1 and a mass percentage of 1% chitosan, stirred for 1 min, and mixed uniformly to prepare the antibacterial agent.

Embodiment 3

[0046]The preparation method of described antibacterial agent comprises the steps:

[0047] (1) be that the active carbon powder that mass volume ratio is 1:15 and mass percentage be 2% bamboo vinegar liquid mix, stir 0.8h, leave standstill 2 days, take out supernatant liquid namely bamboo vinegar liquid;

[0048] (2) The supernatant obtained in the step (1), that is, bamboo vinegar, was mixed with 0.3% chitosan in a volume ratio of 3:1, stirred for 5 min, and mixed uniformly to prepare the bacteriostatic agent.

Abstract

The invention relates to the field of biological agents, mainly relates to a bacteriostatic agent and a preparation method and application thereof and specifically relates to a bacteriostatic agent for preventing and treating bacterial brown spot and a preparation method and application thereof. The bacteriostatic agent is prepared from bamboo vinegar and chitosan, wherein the volume ratio of the bamboo vinegar to the chitosan is (1 to 20):1. The bacteriostatic agent disclosed by the invention has strong pertinence, can specifically aim at pseudomona tolaasii of bacteria through mutual action of the specific proportion of the bamboo vinegar to the chitosan, can effectively kill the pseudomona tolaasii and can prevent and treat brown spot of bacteria.

Description

technical field [0001] The invention relates to the field of biological preparations, and mainly relates to a bacteriostatic agent, its preparation method and application, in particular to a bacteriostatic agent for preventing and treating bacterial brown spot, its preparation method and application. Background technique [0002] Pleurotus ostreatus is one of the four largest edible fungi in the world, and it is also the most cultivated edible fungus. It is difficult to estimate the economic losses caused by pests and diseases every year. In recent years, Pseudomonas tolaasii Paine caused by Pseudomonas tolaasii Paine has caused serious damage and has a wide range of hosts. It can also infect many edible fungi such as Agaricus bisporus and Flammulina velutipes. With the implementation of annual production and the gradual expansion of cultivation scale, the bacterial brown spot of Pleurotus ostreatus is becoming more and more serious, especially in spring and autumn. Once b...
