How can mushroom cultivation be contaminated by miscellaneous bacteria?

How is mushroom cultivation contaminated by miscellaneous bacteria? What are the ways to prevent it? Hope experienced netizens help introduce Generally, mushrooms are often contaminated by miscellaneous bacteria during cultivation, resulting in serious yield reduction and harvest failure of mushrooms; miscellaneous bacteria are generally Trichoderma viride, Qulu, etc., which are one of the most common miscellaneous bacteria in seed production and clinker production. Miscellaneous bacteria can survive in soil and organic materials or gaps in walls in sheds for a long time, spread through air, soil covering materials, tools, etc., The cultivation network sorted out the mushroom planting process in the prevention and control of miscellaneous bacteria methods, the following detailed list for netizens reference. Method 1: Prevention in advance: You can use the hundred diseases to eliminate the trace to completely kill the mushroom shed; spray the bactericidal medicine every 5 days or so during the period of fungus development and fruiting, and alternately use the hundred diseases to eliminate the trace and the mushroom killing disease spirit during production. Method 2: Open all vents and strengthen ventilation at the inlet and outlet of the contaminated mushroom shed; spray all diseases at the same time, and then treat the contaminated bacteria bag. Method 3. Miscellaneous bacteria spot pollution: Take 100 times Xiaomei Wang solution injection to kill measures, such as miscellaneous bacteria spores germinate from the base material, increase the concentration to about 50 times, and deeply insert the needle, so that the liquid medicine oozes from inside to outside, killing effect can reach 100%. Note that the needle insertion point should be above the contaminated point, obliquely inserted and injected, so that the contaminated point is close to the ground. Method IV. Contamination of miscellaneous bacteria: When it is difficult to inject drugs, the plastic film can be cut open at the contaminated place, the plastic film can be opened, and the liquid medicine can be applied. This is only suitable for the miscellaneous bacteria germinating on the surface of the base material, and must be discovered early. Otherwise, it can be sprinkled with powder, and then the plastic film is returned to its original position, and its killing effect is good. Method 5. About 50% of the bacteria bag contaminated by miscellaneous bacteria: flexible treatment according to the situation, such as more than half of the edible fungi seedlings have been sent, that is, the base material has been connected by hyphae, the plastic bag can be removed, the bacteria column is soaked with 150 times of Xiaomei Wang solution, and then the plastic film is covered for bacterial culture; if the pollution occurs heavily, the number of edible fungi hyphae is small, the bacteria bag can be cut longitudinally for 3 to 5 openings, the plastic film is loosened and then soaked for a longer time, and then the bacteria are allowed to grow. Method VI, such as large areas of contamination of miscellaneous bacteria, pollution time more than 15 days, contaminated bacteria bags accounted for about 70%, then the batch of bacteria bags almost no retention value, all bacteria bags cleaned out of the shed, there are two treatment methods: 1. Set up a sunshade, carry out normal disinfection treatment, carry out drug treatment on unpolluted or lightly polluted bacteria bags according to the above, put them in the sunshade for bacteria culture, and directly compost the lost culture value; 2. Pour the contaminated bag, take advantage of fine weather, add lime powder according to 2% of the dry weight, mix well and dry it, and use it as raw material for clinker cultivation or fermentation cultivation. 3. After clearing the shed, thoroughly clean up the sanitation, continuously spray twice every 2 days to eliminate all diseases, remove the covering such as grass cover, close all ventilation holes and inlets, and close the shed. After 3 days of high temperature, the ideal sterilization effect can be achieved; then it can be re-cultured in bags.
