Eliminate virus treatment of Edible Mushroom greenhouse

The most important thing to pay attention to in the cultivation of edible fungi is the prevention and control of diseases and insect pests, and the essence of the problem, in the final analysis, is actually a problem of prevention. Therefore, in the whole production process of edible fungi, we always adhere to the principle of "prevention first". For every producer, it is very necessary. Through the hotline consultation content, combined with the actual investigation, the author found that a large number of mushroom farmers saw the disinfection (disinfection) (germicidal) treatment in the mushroom shed very vaguely, even ignored, although some had some consciousness, but the treatment measures could not be put in place, so they were "unsure" about the occurrence probability or trend of diseases and insect pests in cultivation and production, and appeared to be in a hurry when diseases and insect pests attacked, even using drugs indiscriminately. It is not only a waste of manpower and financial resources, but also makes mushroom products contain a lot of drug residues. This article focuses on the treatment of mushroom shed to discuss with the majority of mushroom farmers, hoping to be helpful to the production of readers.

Principles of requirements for the construction of mushroom shed

The construction of the mushroom shed should be determined according to each person's production plan and production direction, and cannot be generalized. For example, the mushroom farmers planning annual cultivation can raise the standard of the mushroom shed, preferably a winter-warm greenhouse; when giving priority to out-of-season production, the walls should be thickened as far as possible, and "greenhouse water temperature air conditioning" should be installed, which can not only maximize heat preservation, but also achieve free temperature control, laying the foundation for out-of-season production. Up to now, there are still some mushroom farmers who only engage in a batch of cultivation in autumn and winter, so there is no need to build high-standard mushroom sheds. They can build single-slope, plane-type greenhouses, or even simple facilities built on slopes and walls, and the cost is much lower. However, no matter what kind of mushroom shed, it is necessary to grasp a principle, that is, it can basically achieve the purpose of ventilation, heat preservation and moisture preservation, especially the ventilation hole, so that it is better to be as close to the ground as possible. In the past, some "earthen mushroom sheds" were surrounded by airtight walls and rampant diseases, causing too great losses to mushroom farmers. The lesson is profound.

Eliminate virus treatment of Mushroom shed Environment

Strengthen the concept of "environment" and strictly disinfect and sterilize. It is worth noting that our production environment has begun to go from bad to worse, such as contaminated bacterial bags, diseased mushroom bodies and cultivation waste, making it a new "disease source base", resulting in frequent diseases and cross-infections. making sustainable production more and more difficult, this phenomenon has appeared since the 1990s and has not been effectively controlled so far. For base production, we have always emphasized the improvement of this "environment". Under the condition that large area control cannot be achieved, disinfection and sterilization measures can be strengthened in the base: outside the cultivation shed, including the periphery of the operation site, cleaning up sanitation, stable toilets, garbage, etc., especially thoroughly clean up contaminated bacterial bags and bacterial chaff waste, and spray high concentration carbendazim dichlorvos mixture to sterilize and kill insects. People with poor environment should use the medicine twice in a row.

Eliminate virus treatment of new mushroom shed

Drugs such as phoxim and phoxim can be used in the shed. The general dosage is 1 bag of phoxim without trace and 50 g phoxim, spraying about 30 square meters. The target of the medicine is the ground, wall, column, etc., which requires carpet spraying, and then seal the mushroom shed. Roll up the grass to bask in the shed, and after 2 days of sealing, you can put bacteria into the bag or produce mushrooms. During the period of fungus and mushroom emergence, the preventive medicine can be sprayed every 5 days or so, but be careful not to spray the fruiting body directly.

Eliminate virus treatment of old mushroom shed

In the mushroom shed which has been used continuously for many years, it is inevitable that there are a considerable number of miscellaneous bacteria and pathogen spores as well as insect pests in the shed. Therefore, it is very necessary to carry out eliminate virus treatment thoroughly. Generally, 40 grams of phoxim can be dispensed without trace according to a bag of all diseases, about 20 square meters of carpet spray, then seal the mushroom shed, roll up the grass to bask in the shed, seal it for 2 days, use the medicine again and continue to seal the shed, 2-7 days later, the bacteria can be sent into the bag.

Finally, a special point is put forward for readers' reference: cultivation in autumn, especially in early autumn, it is suggested that mushroom farmers cultivated from August to October had better pour heavy water into the shed before dealing with the shed, with underwater infiltration, and carry out drug eliminate virus with reference to the above. Then, before entering the grid, spread the fresh lime powder according to the dosage of 0.25kg per square meter in the shed, and then move it into the bag. In this way, the greenhouse temperature can be reduced, and the activity of some miscellaneous pathogens can be inhibited to the maximum extent, thus reducing the probability of disease occurrence.
