Mushroom cultivation of the main bacteria are green Trichoderma, Qujiao, etc., is one of the most common hybrid bacteria in seed production and clinker production. This type of fungal high temperature and humid environment. Prevention can be used to "kill all diseases without a trace" completely kill the mushroom shed. During the period of germination and mushrooming, a bactericidal drug is sprayed every 5 days or so. The production can be used interchangeably with “without disease†and “mushroom killing disease spiritâ€. For the mushroom sheds that have already been contaminated, all ventilation openings are opened, and the import and export are enhanced for ventilation. At the same time, “blasts without trace†are sprayed, and then the contaminated bacteria bags are treated. For spot contamination, take 100 times the "Kamiyawang" solution for injection and killing measures. For example, if the germination of the fungus spores is raised from the base material, raise the concentration to about 50 times and insert the needle deeper so that the liquid can seep from the inside out. The effect of killing can reach 100%. The method of injecting drugs can also be used for plaque contamination, but the dose should be increased. Injecting and killing the solution should be noted that the insertion point of the needle should be located at the upper side of the contamination point, and be inserted obliquely and injected to make the contamination point close to the ground. When contaminated pollution is difficult to inject drugs, the plastic film at the pollution site can be cut open at the intersection, the plastic film can be opened, and the drug solution can be applied. This only adapts to the germs that germinate on the surface of the base material and must be discovered early. Otherwise, it can be directly sprinkled powder, and then plastic film to the place, the killing effect is good. About 50% of the bacteria bag area pollution, depending on the situation flexible treatment, such as edible mushroom seedlings have been sent to more than half, that is, the base material has been connected by the mycelium, can remove plastic bags, matching 150 times "Mill" The solution is immersed in the fungus and then covered with a plastic film to be cultured; if the pollution is heavy and the number of edible mycelium is small, 3 to 5 ports can be cut longitudinally on the bag, and the film can be washed after loosening. Slightly longer, then let it settle. If there is a large area of ​​pollution, the pollution time is more than 15 days, and the contamination bag accounted for about 70%, the batch of bacteria bags will have almost no reserve value. After the bacteria bags are all cleared out of the shed, there are two methods of disposal: 1 In the shed, after the normal killing treatment, the uncontaminated or less polluted bacterium bags are subjected to drug treatment and placed under the awning to grow bacteria and culture, which will lose the direct cultivation of the cultivation value; 2 the pollution bags will be poured and the lice will be sunny. In the weather, lime powder is added at 2% of the dry weight, mixed and dried, and used as a clinker cultivation or fermentation material for cultivation. After clearing the shed, thoroughly clean the sanitation, spray 2 times in a row on two consecutive days, “everything goes without a trace,†and remove the coverings such as grasshoppers, close all the ventilation holes and the import and export, and put it in a stuffy shed, after about two days of high temperature Straw shed, you can achieve a better killing effect of bacteria, and then you can re-bag culture.
