New technology helps Pleurotus ostreatus outbreak

The so-called "outbreak of mushrooms", that is, when the edible fungi are cultivated, artificially regulate the growth conditions, so that the mushroom formation "explosion", so that the original 3 to 5 months, the mushroom 3 to 4 tide, biology With an efficiency of about 100% growth, once the “outbreak of mushrooms” occurs, 80% or even 100% of the total output of traditional cultivation can be produced at one time, and the biological efficiency can exceed 150%, which can shorten the cultivation management time and increase the mushroom. Product quality, input-output ratio has been greatly improved. The technical points of Pleurotus ostreatus "outbreak of mushrooms" are introduced as follows:

1. Detoxification treatment or introduction of detoxification strains

The strains that have been detoxified by scientific methods do not carry any virus pathogens themselves, and during the detoxification operation, after continuous high-temperature-low temperature exercise, the resistance of the strains is also improved accordingly. There are problems such as species degradation.

Second, adjust the nutritional composition of the base and its level

In general production, the formula can be designed according to the cultivation materials. In general, it should mainly be supplemented with nutrients mainly composed of trace elements. For example, when cottonseed hull is used as the main material, 120 g of edible fungus three-dimensional nutrient concentrate (mixing type) can be added per 250 kg of dry material, so that the nutrient components of the base material can be scientifically rationalized and comprehensively balanced, which provides strong growth for mycelium growth. The material basis.

3. Sterilization and sterilization of strict cultivation environment

At present, a large number of studies have shown that the addition of Saibai 09 and other antiseptic drugs in the base material can improve the success rate of the bacteria. While sterilizing the base material, it is necessary to carry out strict disinfection and sterilization treatment on the spray site.

Fourth, strengthen the mycelial culture

Once the mushroom is finished, it will soon be budded, but if the mushroom is not good, it will cause headaches such as difficulty in mushrooming and disease. Of course, the occurrence of the problem is not the result of a single factor, such as insufficient number of hyphae and less biomass reserves. Experiments have shown that under a certain range, under the same variety, base material and other conditions, the post-maturation period of mycelium has a very close relationship with the biological efficiency of the first mushroom. Therefore, under the premise of adjusting the nutrients of the base material, it is possible to extend the post-ripening time of the hyphae as much as possible, generally about 15 days. This method maximizes the bioenergy of the mushroom.

5. Fruiting stage combined with foliar fertilization

Generally, when the diameter of the cap is about 2cm, the edible mushroom three-dimensional nutrient sperm (spray type) can be sprayed, and the fruit body can be directly sprayed, and each mushroom can be sprayed 3 times to achieve the best yield increasing effect, and at the same time Improve the quality of mushroom products and enhance the advantages of resistance, so as to enhance the effect of "outbreak of mushrooms".

6. Preventive use of drugs to prevent and control pests and diseases

Since only a mushroom is erupted, the time is short, and the pests and diseases are basically not likely to occur. Therefore, it is only necessary to carry out preventive medication, and there are many headaches such as loss due to pests and diseases.
