A Cultivation Technology of Dictyophora edulis with Free Bundling and Secondary Fermentation Layer Sowing

Abstract

The present invention provides a second fermentation layer sowing cultivation process for red-carved bamboo fungus without making bags. The process adopts secondary fermentation, and reasonably controls the fermentation temperature and time, etc., so as to realize the red-carved red-carved second-fermentation layer sowing without bagging. The production process of bamboo fungus, through the use of two fermentation and layer sowing operations, eliminates the process of bagging and sterilization, and greatly reduces the pollution rate, reduces production costs, and increases the output of bamboo fungus.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation, and in particular relates to a secondary fermentation layer-sowing cultivation technique of red-twisted bamboo fungus without making bags. Background technique [0002] Dictyophora, also known as bamboo fungus and bamboo ginseng, is a cryptogamous fungus parasitic on the roots of dry bamboos. Its shape is slightly reticulate and dry white snake skin. It has a dark green cap and a snow-white cylindrical stipe. The pink egg-shaped receptacle has a delicate white mesh skirt on the top of the stipe that spreads downward from the cap. It is called "Snow Skirt Fairy", "Flower of Mountain Treasures", and "Flower of Fungi". , "Queen of bacteria". Dictyophora is rich in nutrition, rich in fragrance and delicious in taste. It has been listed as one of the "Eight Treasures of Grass" since ancient times. [0003] Hongtuo bamboo fungus is a characteristic edible fungus in Guizhou, and it ca...

Problems solved by technology

The common cultivation process of Dictyophora edulis in China is as follows: use polyethylene plastic as the container to fill the medium with manual or semi-mechanized equipment, then sterilize at 100 degrees Celsius under normal pressure for 48 hours, cool down to make a support rod and transfer it to the inoculation room After inoculation, transfer to the culture bank for 100-120 days and then cover with soil for cultivation. This process has a long production cycle, huge labor, and high pollution rate, which has become a bottleneck restricting the development of Guizhou Hongtuo Dictyophora industry. Specifically, the existing production process has the following disadvantages : (1) The labor cost is high. The existing mode uses manual or semi-mechanized bagging to produce bamboo fungus sticks. After 120 days of cultivation, the plastic is removed and the soil is planted in a greenhouse. During this period, the sticks need to be made manually, inoculated manually, and Soil-covered cultivation leads to high labor costs in the entire production process; (2) high energy consumption. In the existing production mode, raw and auxiliary materials must be steam sterilized after being bagged and packaged. Usually, atmospheric pressure sterilization requires 100°C steam Continuous sterilization for 48 hours consumes a lot of energy during the period; (3) pollutes the environment, the existing production mode uses polypropylene or polyethylene bags to produce mushroom sticks, and the bags need to be removed again in the later fruiting stage, and the delayed bags are easy to cause Environmental pollution; (4) The contamination rate of bacteria sticks is high. The production of traditional bacteria sticks relies on the aseptic environment inside or outside the bacteria bag to maintain the production of Dictyophora mycelium, such as incomplete sterilization, microporous bags, and poor cultivation environment. If it is qualified, it will cause a large area of ​​pollution. The pollution rate of conventional red-tuo bamboo fungus sticks is 40% higher.
