The so-called "eruption of mushroom", that is, in the cultivation of edible fungi, through the artificial regulation of growing conditions, making it mushroom out of the "burst" trend, so that the original up to 3 to 5 months, 3~4 tide mushroom, biology With an efficiency of 100% or so, once the “eruption of mushroom†is performed, 80% or even 100% of the total yield of the traditional cultivation can be produced at one time. The biological efficiency can exceed 150%, which can shorten the cultivation and management time and increase the mushroom productivity. Quality of products, input-output ratio greatly improved. The technical highlights of the "explosive mushrooms" of Pleurotus ostreatus are described below:
I. Detoxify strains or introduce detoxification strains
The strains that have been detoxified by the scientific method will not carry any virus pathogens themselves, and after a continuous high-temperature and low-temperature exercise during the detoxification operation, the resistance of the strains will be correspondingly improved. There are problems such as species degradation.
Second, adjust the nutritional composition of the base material and its level
In general production, formulas can be designed based on cultivation materials. Overall, they should mainly be supplemented with nutrients mainly composed of trace elements. If cottonseed husks are used as the main ingredient, 120g edible fungi can be added into the three-dimensional nutrient auxin (mixing type) per 250 kg of dry material, so that the nutrient components of the basal material can be scientifically reasonable, fully balanced, and provide strong growth for mycelium growth. The material basis.
III. Sterilization and sterilization of strict cultivation environment
At present, a large number of studies have shown that adding bacteriostatic drugs such as Saibai 09 to the base can increase the success rate of bacterial infection. While sterilizing the base material, it is necessary to strictly disinfect and sterilize the germination site.
Fourth, strengthen the hyphae after maturing culture
Once the mushroom has completed its germination, budding will occur quickly. However, if a mushroom does not produce well, it will cause problems such as difficult mushrooms and many diseases. Of course, the occurrence of problems is not the result of a single factor. There are constraints such as insufficient number of hyphae and low biomass reserves. Experiments have shown that within a certain range, under the conditions of the same variety, base material, etc., the hyphal ripening period has a very close relationship with improving the biological efficiency of the first tidal mushroom. Therefore, under the premise of adjusting the nutrient content of the base material, the post-ripening time of the hyphae can be extended as much as possible, generally about 15 days. This method can maximize the reserve of bioenergy burst mushroom.
Fifth, fruiting stage with leaf surface fertilization
Generally, when the diameter of the cap reaches about 2cm, the edible fungus can be sprayed on the three-dimensional nutrient essence (spray type), and the fruit body can be directly sprayed, and each wave mushroom can be sprayed three times to achieve the best yield increase effect, and at the same time Improve the quality of mushroom products and increase the resistance, which can strengthen the "eruption mushroom" effect.
Sixth, preventive use of drugs to prevent pests and diseases
Since only a single mushroom erupts, the time is short, and there is no chance of occurrence of diseases and insect pests. Therefore, it is sufficient to apply preventive medicine alone, and there are no headaches such as loss due to pests and diseases.
